Rewilding the abandoned thoughts on master thesis1 Estonian cityscapes are being developed as fast as left behind. After many different changes in administrative laws during the 20th century there is now over 102 totally abandoned villages in Estonia. People are moving to the bigger cities, Tallinn is growing continously. But even in the middle of Tallinn one can find abandoned spaces here and there. By spaces I mean not only buildings but parks, streets, rooms, playgrounds, furniture etc. I wouldn’t dig into the question why they are left unused or how to keep spaces useful but the processes happening after the abandonment. I think that ruining processes keep the city alive, they shouldn’t be stopped. What is the meaning of spatial abandonment? Does it mean, that the man-made boxes aren’t taken care of anymore or does it mean that they are being used differently. Why are buildings used by homeless people abandoned even though someone can now call them a home? Does it mean that a space that starts making its own rules, it is useless? What about spaces full of municipal waste? Are they living or are they dead? The same question arises when looking at deserted and overgrown man-made spaces. The spaces that are overgrown by nature and left for free usage, start to lose their initial built borders. The windows break, the walls become ruins, the plants grow indoors, the exterior-interior definition becomes questionable. A new life grows in, abandonment becomes questionable. Our sense of space has developed in wilderness without borders. Losing artificial borders encourages freedom of spatial interpretation and imagination. Jaan Kaplinski: „Inimese instinktid sündisid suures osas metsikus maailmas – ebamäärasuses, kus igal hommikul ärgates tuli teha otsuseid vastavalt end ümbritsevale keskkonnale. Nüüd on meil kadunud selline vajadus, me oleme ise loonud endale süsteemi, teame igal hommikul ärgates, mis meid ees ootab ning teame isegi seda, kuidas veedame oma vanaduspõlve. Aga tegelikult me vajame sellist ebamäärast keskkonda, inimene on olend, kes tahab otsida ja avastada, aga tal pole enam aega või paikagi kus seda teha.“ Architect Marco Casagrande has said: «Nature is the only reality» and I belive that design should not replace reality but step into a dialouge with nature. I would like to invesigate how create a changing mixture of a ruin and a construction site in alliance with wilderness. How to connect unpredictable nature and regulated artificial worlds in a place, that no longer serves its initial purpose? What would a systemized way of thinking, or even a modular „first-aid kit“ look like? I would like to find „an Estonian way“ of dealing with abandoned spaces. What for me is essential creatng a estonian space is nature but besides that, an ambition to develop the infrastructure and become a real Scandinavian country. Here I belive we could be one step ahead (even though our cities now are at least one step behind of every scandinavian city) - we could bring nature back to the city before we destroy it totally. Besides green thinking, 0-energy building, reusing, reducing, recycling... rewilding the cities is becoming a new trend. Although „rewlding“ is generally used to refer to big-scale conservation efforts to protect, restore, and connect wilderness areas, rewilding is equally applicable to cities and surrounding natural areas. The notion can also be applied to nature uncontrollable overgrowing artificial spaces, in my field of intrest – spaces that are claimed to be useless.

Artificial space built

used space what ?


abandoned space / unused space

if it is unused (the way it was built for), is it useless?

abandoned characteristics

city, street, time, money, building, estate, unnecstreet, park, essary element, etc

the initial value and purpose is gone. the borders start to blur, the space starts to merge with the surrounding when there is no human care. the space is named useless for society, but useful for the repelled.


rewilding restoration vandalism: isolation: recycling: nature taking random / concious or People taking over, breaking intentional unconcious over ( hooliborders, overgans, homeless growing people). new breaking down articial elements, waste, space garbage etc new spatial situations, is dead new life Still useless, dead, limited?

- “The juxtaposition of new growth against old structure creates a nice tension, and the dead leaves and stems on the wrought iron step create a nice bridge.” Chris McGee, Lam Art Director - Marco Casagrande: „Design should not replace reality.“ His method: Invesigating, creating a constantly changing mixture of a ruin and a construction site. - Do we need urban wilderness? We have studies showing that people tend to be healthier and happier, and can enjoy longer lives, in areas where they have access to nature, including green urban spaces. Outdoor spaces are some of the least expensive to create and can pay some of the highest returns on investment—in terms of community life, health and wellness, and the generation of economic activity in surrounding areas. As more people—from young professionals to retirees—move back into cities, green public spaces and vibrant streetscapes are often cited as key factors for attracting residents and businesses. Despite this, we do not give outdoor spaces the same value and financial support that we give to buildings and interiors. We calculate the square-foot dollar value of buildings and interiors but don’t do the same for a square foot outdoors. We have not made a strong business case for designed outdoor spaces—we can and should be making this case. I also believe that design and innovation in public and privately owned outdoor space is lagging. - What happenes with abandoned buildiing? When a building is abandoned, it is no longer sealed in a way to keep environmental elements out. Even if the building is well sealed, simply having the temperature drop to levels that would normally be controlled by human comfort standards, will create an environment that will be more likely to promote organic growth, which leads to mould and decay. Humans will naturally protect their home without even realizing it.

Näiteid hüljatud hoonete ja linnaruumi ajutistest kasutustest Tallinnas Kaija-Luisa Kurik “Väita, et linnas on liiga palju ruumi tundub lihtsustav, kuid Tallinnat on pikalt iseloomustanud omapärane laialivalguvus ning linnasisese tiheduse puudumine. Hõredusse on pikitud mõned keerulised kuid põnevad hüljatud maamärgid, funktsiooni kaotanud tähenduslikud hooned, problemaatilised elamualad. Südalinna areng ning äärelinnade mitemekesistumine on kindlasti olulised teemad Tallinna tänases ja tuleviku arengus. Ajutised kasutused on kõikjal ja mitmekesised, kuid urbanistile on just huvitav küsimus, millistel tühjade ruumide ajutistel kasutustel võiks olla kestev linna arengut suunav ja soodustav mõju ning kuidas seda erinevate osapoolte koostöös rõhutada.” Kuidas saaksid uued kasutusstrateegiad hõlmata ühe paiga varasemat identiteeti?

ghts thouLoodus – näide piiridest, mis pole küsitavad Loodus on inimestele kõige ühiseltmõistetavam keskkond, sest meie ruumitaju ja instinktid on välja arenenud metsikus looduses, kus pole piire. Tehislike piiride kaotamine annab võimalusi tõlgendamiseks, vabadustundeks. Tõlgendusvabadus laseb igal indiviidil luua ühisesse ehitatud keskkonda oma maailm. Loodus hägustab (linna) piire füüsiliselt, kaotab meie loodud geomeetriad, looduslik keskkond jätab meile ruumitunnetusliku tõlgendusvabaduse. Looduse toomine linna tagasi aitab meid viia tagasi oma ideaalruumi, mida me saame sõnastada enda tahtmise järgi, annaks inimesele näiliselt rohkem vabandust kujundada ise maailm enda ümber.

EIK: “Do you want to restrain (and make use of) an abanoned space or rewild (let it grow) an abandoned space ?” Andrea: “...REWILD”

A RFFERENCE FELING OF THE DAY 12.10.2016: “An animal was taken to WILDerness to CALM down” WILD / CALM RESTRAIN / REWILD

THE WILDERNESS CITY: An Essay on METAPHORICAL EXPERIENCE by Arnold Berleant - “Thc city is a fact in nature, like a cave, a run of mackerel or an ant-heap. But it is also a conscious work of art, and it holds within its communal framework many simpler and more personal forms of art. Mind takes form in the city; and in turn, urban forms condition mind.” Mumford 1938, Introduction - “Just as language has no longer anything in common with the thing it names, so the movements of most of the people who live in cities have lost their connexion with the earth; they hang, as it were, in the air, hover in all directions, and find no place where they can settle.” Rainer Maria Rilke, Worpswede (1903) - W. R. Burnett, The Asphalt Jungle, 1949; “The city is not a concrete jungle, it is a human zoo.” - THE GARDEN CITY MOVEMENT The ‘garden city’ conveys a fusion of nature and culture, a cultivated nature in which control takes a quietly benevolent course in promoting the flowering of people’s lives in an Edenic urban setting (Howard 1945, Stein 1957). This idealised garden city would house 32,000 people on a site of 6,000 acres (2,400 ha), planned on a concentric pattern with open spaces, public parks and six radial boulevards, 120 ft (37 m) wide, extending from the centre. The garden city would be self-sufficient and when it reached full population, another garden city would be developed nearby. Howard envisaged a cluster of several garden cities as satellites of a central city of 58,000 people, linked by road and rail. - Finnish forest communities. Munkkiniemi,Tapiola. Tapiola’s planners aimed at demonstrating a new direction for Finnish town planning and housing. The aim of the Housing Foundation was to create a garden city which would be a microcosm of Finnish society: all social classes would live there and there would be different types of buildings, ranging from detached houses to terraced and multi-storey blocks

quotes from author Arnold Berleant: - Over the past hundred years, ‘wilderness’ is becoming a place to be valued and protected, a source of values and of human connections with the rest of the natural world (Rolston 1989: 118–143). - “wilderness” as a methapor: Thinking of the city as wilderness leads us in unusual directions. We may, at times consider the city overwhelming and hostile, not a place for preserving and promoting human values. Its unfamiliarity makes the city appear confusing, threatening in its very strangeness. - Constant concern over making a misstep influences our passage through both city and wilderness, while the background apprehension of danger from motor vehicles and muggers parallels the constant threat, real or imagined, from the deadly creatures thought to inhabit a wilderness. In both city and wilderness, feeling out of place is a vivid component of the experience. With familiarity, the wilderness city may change into something different, such as a park or jungle. The last of these finds common ground between tribal warfare and the urban dangers of gang wars. As a metaphor, wilderness preserves its darkness. - When traffic becomes a torrent and urban crime is endemic, the city is described as a jungle, the reference being to the threatening features of wild nature. - We have noted how the idea of wilderness is historically conditioned, changing in the eighteenth century from a wild place by darkness, danger, and desolation, to one where we can encounter, admire, and enjoy nature. This transformation in meaning is part of a process that still continues, as we reconfigure nature from a threat into a resource, from a source of wealth into a haven of respite from the pressures of urban life, from a playground into a domain demanding respect for its own inherent values. - Wilderness as a natural environment exists more in history and imagination than in fact. Withthe disappearance of most of the primeval forests we have left only what are called, oxymoronically, wilderness parks. These are usually secondary ‘wildernesses,’ land grown over after the original logging and farming activities have been abandoned. Even these wildernesses are cultivated in the sense of being protected, often managed, always surrounded and impinged upon by human activities. - Perhaps, in a similar fashion, the primeval wilderness has been overgrown in human experience by the city. The metaphor suggests that the city has become the new wilderness, evoking, on the one hand, feelings of intimidation and awe, a sense of the infinite, and the experience of absolute dependency; and on the other, danger and the wild behavioral traits of hostility, aggression, and violence. - When we speak of a garden city, we are not merely using a figurative expression. We are extolling the garden as a model for urban life and a qualitative goal of urban design. The wilderness city has not, to my knowledge, been taken as such a model. It stands not as a goal but as a graphic expression of anguish at what urban experience has become for many less fortunate inhabitants of the modern city.

rewilding the abandoned research and action plan Can wilderness vitalize the vacant cityscape? .... is the research question ?


....are the core questions I would like to answer? I want to achive?

- What are the alternative solutions for abandoned spaces? - What qualities could nature add to the vacant cityscape? - How to build a city / create an interior in collaboration with nature? - When nature starts breaking the artificial borders how does it change the meaning of space? - How does an overgrown building change in time (grow further, react to seasonality, weather, human activity etc)? - How would an Estonian wild urban space look like? I want to - explore the aesthetics of decay - give and abandoned space a new quality. - rewild not to restrain the abandoned space. - rethink the meaning of urban green areas not build new parks - create a direct connection between landscape and interior architecture - create a wild interior space. - break the artificial borders that do not represent the meaning of the space as we perceive them. - learn from nature, work with not against it

rewilding the abandoned research and action plan


....did I choose the topic? ....why is the topic relevant?

I started with questioning the way we artificially and verbally build borders around us. I am intrigued by man-built spaces but I am also intrigued by the freedom of boarderless wilderness. I believe that every person has a need for wilderness. Green lifestyle and development of parks is becoming more and more popular and needed around the world. But superorganised parks are far from wilderness aesthetics.

- The amount of vacant buildings on high-cost sites in Tallinn centre is quite big. Many of the buildings are in ruins and cannot be renovated and are already overgrown by nature - Rethinking the green areas might be a solution for the vacant spaces in dense cities, bringing natural freedom to the cityscape. - Although vast majority of Estonia is still covered natural forrest and not much consideration is given to nature while developing cities, Tallinn is becoming landscape more and more artificial. Here we could be one step ahead and contribute rewilding the unused vacant spaces rather than pushing the nature out.

PLANTS AND TREES OF TALLINN - Tallinna piirest on leitud suuremat osa Eesti looduslikke liike. /.../ Inimene avab elupaiku, kus saavad kasvama hakata ja koduneda kaupadega toodud võõramaa taimed. Peaaegu kõiki Eesti tulnukliike on leitud ka pealinnast. Looduslikud liigid on omased eelkõige linna äärealadele, mida pole jõutud täis ehitada. - Rannataimed – looduslikud liigid keset linna. Palju tulnukliike, millest paljud Eesti niiskes kliimas ka enamasti ei valmi, sest lähevad enne hallitama - Tallinna süda paikneb paelaval. Looalade taimi on säilinud Lasnamäe servas ja Kadaka küla juures. Lasnamäe klindineemik on ainus alpi kadakkaera elupaik Eestis. Lootaimed (nt Lasnamäe loopealsetel aladel) ei karda üldiselt linna, neid lämmatab vaid prügi laotamine või ehitustegevus. - Salumetsade taimed peaksid ennast linnas kõige paremini tundma. Metsaalused varjutaimed ei armasta peale tallamise ka niitmist. Seetõttu on ka salutaimi rohkem linna ääres.

tõelised linnatänava taimed - suur teeleht, aasnurmikas ja murunurmikas, vesihein

Linnamüüri pragudes:

põisjalg, müürilill (pärit Kesk-Euroopa kaljudelt)

Linnas levivad salutaimed:

salukõdrik, kõrvenõges, naat,

looalade taimed - alpi

kadakkera, aasnelk, püstkivirik, alpi nurmik, rannamõisa tuhkpuu (ainult Lasnamäel)

-Rabade muutused linnas on sarnased liivaste metsade omadega: inimene oma tahtliku tegevusega, samuti õhusaaste ning koduloomad ja inimkaaslevad linnud on muutnud keskkonna toitainerikkamaks kui tavalises laguneva turbaga raba-kõdusoos. - Linnadesse loovad liigirikkust ka tulnuktaimed. Suurtesse linnadesse jõuavad nad enamasti ikka – siin on kaupade laadimist ja põllumajandustoorme töötlemist. Need on peamised inimkaaslevate taimede levitajad. Tulnuktaimedel on linnas hea püsima jääda selle tõttu, et siin on palju rikutud elupaiku, vaba pinda, kus seemned saavad konkurentsitult idaneda. Ka linna soojem kliima soodustab lõunamaalaste ellujäämist. Suurem osa tulnuktaimedest ongi pärit lõuna poolt. - Tulnuktaimedel on linnas hea püsima jääda selle tõttu, et siin on palju rikutud elupaiku, vaba pinda, kus seemned saavad konkurentsitult idaneda.

FRAGMENTS of URBAN WILDERNESS tallinn september 2016

interesting note: a building starts overgrowing from the ground and the roof


How can plants grow out of concrete or abandoned buildings? - Air etc. dispersed seeds of certain plants would land in the cracks and crevices of buildings and establish there. These range from ephemeral (ühe-aastane) types to perennials (mitme-aastane). - Water: intermittent rainfalls, episodes of dew or leaking plumbing/drainage. Some plants survive through prolonged intermittent droughts. - Soil: A lot of plants need sheltered conditions but not much soil to start growing in. Plant roots are really really thin they can easily extend through the bottom of the crack in concrete into the soil below.

Ruderaaltaimed on kiirekasvulised ja tõhusa seemnelise uuenemisega taimed, mis kiiresti asustavad taimkattest vabanenud kasvukohti. Ruderaaltaimedeks võidakse nimetada ka umbrohutaimi. Ruderaaltaimede asustatud ala nim. ruderaalpaigaks.

RUDERAL PLANTS in TALLINN ruderal - a plant growing in waste places, along roadsides or in rubbish.

1st to grow

Moss (sammal)

Japanese knotweed (Sahhalini konnatatar)

Moss grows naturally in areas that are shady, acidic, moist, sheltered, It spreads like fire, and will take and free from other plant compe- over gardens and parks, illegal in tition. The urban landscape is a some contries natural fit for moss.. The soils are typically compacted and deficient. Moss likes hard, compact soil. Moss will not survive a pH higher than 6.5.

Dandellion (võilill) Spreads quickly, strong roots, can grow almost everywhere

Naat, Teeleht, Jasmiin (tugevad juured), Luuderohi (annab värvi), metsviinamari

Pihlakas, Vaher, Pärn


Kahjustusprotsessid grupeeritakse: - füüsikalised kahjustused tekivad materjalide niiskusesisalduse muutumisel kaasnevate mahumuutuste ning soojus- ja valgusenergia põhjustatud mõõtmete ja molekulaarstruktuuri muutuste tõttu. Talvised külmumis- ja sulamistsüklid, Kivimaterjalide soolakahjustused, valguskiirgus. - keemilised kahjustused mitmesugused reaktsioonid (hüdrolüüs, oksüdatsioon, korrosioon jpt), mis on esile kutsutud nii materjalide endi keemiliste koostisainete reageerimisest kui ka väliskeskkonnast materjalidesse sattuvate ainete toimest. Väävedioksiid jm saasteained, korrosioon, karboniseerumine. - mehaanilised KAHJUSTUSED põhjustatud mehaaniliste jõudude toimest (deformatsioon, purunemine, rebenemine, kulumine, abrasioon) ja pinna määrdumisest. Tegemist on sageli esinevate, küllaltki suurte ja väga mitmepalgeliste kahjustusprotsessidega, mis osaliselt kattuvad ka teiste kahjustusprotsessidega. Tuul, erosioon, sadenevad soolad, - bioloogilised KAHJUSTUSED Bioloogilised kahjustusprotsessid tekivad mitmesuguste organismide (bakterid, aktinomütseedid, mikroseened, putukad, närilised jne) elutegevusest, enamasti on tegemist olemuselt keemiliste või mehaaniliste kahjustustega, mis on tekitatud organismide poolt.

BIOKAHJUSTUS: H. J. Huecki (2001) pakutud klassikalise defi nitsiooni kohaselt on biokahjustus igasugune ebasoovitav muutus materjalide omadustes, mis on esile kutsutud organismide elutegevusega. Biokahjustusprotsessid saavad toimuda ainult siis, kui keskkonnatingimused on sobivad neid põhjustavate organismide kasvuks ja arenguks. Igasuguse biokahjustuse korral on olulisteks osalisteks selles protsessis (joonis 3): - materjal, mida kahjustatakse; - organismid, kes kahjustavad (biokahjustajad) - keskkond, mis mõjutab nii organisme kui ka materjale. Organisme mõjutavatest keskkonnateguritest on olulisimad: - niiskus - temperatuur - hapnik - valgus.

Jäätmaade puhul eristatakse nelja suktsessioonijärkjärku (üksteisele järgnevat protsessi): 1. avatud kooslus arvukate üheaastaste pioneertaimedega. 1-2 aastat 2. avatud kooslus mitmeaastaste rohttaimede ja üksikute põõsastega 3. poolavatud kooslus arvukate põõsaste ja üksikute puudega. 4. Vanimad jäätmad on peaaegu täielikult kaetud metsaga Jäätmaa on ala, mida inimene on varem kasutanud, mis aga seejärel on olnud inimtegevusest vähemalt aasta puutumata. Sellised alad on tühjad krundid, laoterritooriumid, tagahoovid jne. Jäätmaadel kujuneb välja iseloomulik taimestik, kus valitsevad mitmeaastased suured rohttaimed. Jäätmaade mullad on enamasti toitaine- ja mullaelustikuvaesed, kuivad, hüdrofoobsed (halvasti vett imavad) ja oma koostise, kuivuse ning segipööratud struktuuri tõttu keskmisest soojemad. Sageli on jäätmaa muld kas kokku pressitud, kaetud hoonete ja asfaldiga, kooritud, asendatud või segunenud mujalt toodud kasvupinnasega. See mõjutab mulla omadusi, mis omakorda tingib iseloomuliku taimestiku. Näiteks killustiku- ja betoonirikkas pinnases võib leida kasvamas keskmisest rohkem lubjalembeseid taimi. TaimeSTIK. Eesti taimkattetüüpide klassifikatsiooni järgi on jäätmaade taimkate arvatud ruderaaltaimkonda (pärismaised taimeliigid + tulnuktaimed, 1- ja mitmeaastased). Jäätmaad ilmestavad väidet, et loodus ei salli tühja kohta. Aja jooksul muutuvad nad aina lopsakamaks, võsastuvad ja metsastuvad. Elurikkamad jäätmaad väärivad suisa kaitse alla võtmist, ülejäänud tasub kujundada paljuotstarbeliseks rohe- ja virgestusalaks.

KUIDAS HINNAA PUITMAJA TERVIST? Kalle Pilt (puidu biokahjustuste ekspert) Puithoonet mõjutavad enim: - Niiskus - seened - putukad - biokihid - taimed - närilised, loomad - puidu deformatsioonid

Kuidas kaardistada puitmajade seisukorda? 1. VÄLJAST - Määrake ilmakaared ning hoone paiknemine nende suhtes. - Vaadake, kuhu valgub maja ümber olev pinnavesi: kas maja poole või majast eemale. - Vaadelge, kuidas paikneb hoone ümbruses olev haljastus (puud, põõsad, ronitaimed jne) ning kus puutuvad need kokku hooneosadega. - Vaadake üle hoone katus. Kontrollida tuleks katusekatte terviklikkust ning kinnitust, pragusid ja lõhesid katusekattes. - Sadevee äravoolusüsteemi toimimise juures vaadake, kas rennid on kenasti kaldu äravoolukohtade suunas - kas torud on terved ning lõpevad maapinna lähedal. - Vaadake, kus puutub pinnas kokku vundamendiga ning ehk isegi seina alaosaga ning kui suur osa jääb pinnase vastu. - Kui vundamendis on tuulutus­avad, tuleks kõik läbi käia ning kontrollida, kas avad on puhtad ning kas õhk nendes liigub. - Vaadake üle seinakattematerjal. Krohvi puhul tuleks otsida pragusid ning lahtiseid osasid. Laudise juures on tähtis laudade ühtlus ning kindlasti laudisejoon – kas see on kogu hoone ulatuses sirge või on kusagil kõrgemaid või madalamaid kohti. - Eraldi tuleks vaadelda igasuguseid väljaehitisi ning juurdeehitisi: kas ühendus põhihoonega on kogu piirde ulatuses tihe. Kuidas kaardistada puitmajade seisukorda? 2. SEEST - Esik. välisuks: kas see sulgub tihedalt ning kas lävepakk on vastu ukse alumist äärt. Siis kindlasti põrandakattematerjal ning selle korrashoid, sest esikus on jalgadega sisse toodav vee kogus suur. - Uurige, kas kusagil on puitpõrand vajunud või õõtsub ning kas kivipõrandal on tekkinud pragusid või lohkusid. - Esiku seintel ning laes võiks otsida hallitust ning niiskusekahjustusi (laigud, vöödid seintel, värvierinevused). Samuti sõltuvalt seinakattematerjalist selle korrasolekut – praod krohvis ning lahti tulnud või mädanenud laudis. ... - kelder - niisked ruumid - eluruumid - pööning

Green walls can be often categorized into two types: green facades and living walls. Green facades are a type of green wall system in which climbing plants or cascading ground covers are trained to cover specially designed supporting structures. Rooted at the base of these structures, in the ground, in intermediate planters or even on rooftops, the plants typically take 3-5 years before achieving full coverage. Green facade can be anchored to exiting walls or built as free standing structures, such as fences or columns. Factors for a successful green wall - How the system will be secured to the wall surface - Calculation of loading capacity, waterproofing and substrate layer. - Source of irrigation and mineral nutrients for plants - Appropriate plant selection with consideration of plant spacing, desired coverage, light exposure, hardiness and amenity context. - Plant maintenance plan to secure the health of these living systems - Water recycling and drainage - Light sources Living walls are artificial systems, composed of pre-vegetated panels, often vertical modules or planted blankets that are fixed vertically to a structural wall. Plants are usually rooted directly in the structure / growth medium and they often require irrigation system to addition of mineral nutrients. Any plant species, even moss can be grown on a living wall system. Indoor walls are usually planted with tropical species due to the constant mild temperature and the lack of light while outdoor walls are more restricted to rustic plants. The common systems in this category are felt pocket system & mat media system.


WILLIAM LEE Surface design BIOGRADABLE SEEDED CONCRETE William studied Textiles and Surface Design at Bucks New University. He has a strong interest in material development which allows him to work with individuals both within and outside his chose field. “In collaboration with a materials scientist and Shire Green Roof Substrates Ltd, I have developed a biodegradable ‘seeded’ concrete, which further combines architectural design with nature. Creating specially developed concrete material, with seeds embedded within it, provides a unique opportunity to welcome nature within architectural design. As well as provide a solution to lost habitats of native wildlife and flower species, together with getting people to reconnect with nature in an otherwise ‘baron’ landscape for plants. With a similar consistency of ‘regular’ concrete, seeds start to germinate once water is added to the material. Plant growth through the substance slowly breaking down the material, which decomposes into soil. Becoming completely biodegradable.”

books to read - book “Material Senescence” by Benjamin Busch Borrowing a term from biology, the author uses senescence to describe the ecological aging of architectural fabric in Material Senescence. Text and photographs draw from instances of failing architecture in Berlin to speculate upon the unpredictable breaking down of materials in the built environment. Foreword by Mark Minkjan titled “Transience: the Nature of Architecture”.

- book “The Aesthetics of Decay: Nothingness, Nostalgia, and the Absence of Reason” by Dylan Trigg In The Aesthetics of Decay, Dylan Trigg confronts the remnants from the fallout of post-industrialism and postmodernism. Through a considered analysis of memory, place, and nostalgia, Trigg argues that the decline of reason enables a critique of progress to emerge. In this ambitious work, Trigg aims to reassess the direction of progress by situating it in a spatial context. In doing so, he applies his critique of rationality to modern ruins. The derelict factory, abandoned asylum, and urban alleyway all become allies in Trigg’s attack on a fixed image of temporality and progress. The Aesthetics of Decay offers a model of post-rational aesthetics in which spatial order is challenged by an affirmative ethics of ruin. - book “Industrial Ruins: Space, Aesthetics and Materiality” by Tim Edensor Standing in contrast to these aesthetically and socially regulated spaces are the neglected sites of industrial ruins, places on the margin which accommodate transgressive and playful activities. Providing a different aesthetic to the over-designed spaces of the city, ruins evoke an aesthetics of disorder, surprise and sensuality, offering ghostly glimpses into the past and a tactile encounter with space and materiality. Tim Edensor highlights the danger of destroying such evocative sites in order to build new developments. It is precisely their fragmentary nature and lack of fixed meaning that render ruins deeply meaningful. They blur boundaries between rural and urban, past and present and are intimately tied to memory, desire and a sense of place. Stunningly illustrated throughout, this book celebrates industrial ruins and reveals what they can tell us about ourselves and our past.

Transience: the Nature of Architecture book “Material Senescence” by Benjamin Busch In contemporary society, people have come to see the relationship between city and nature as a dichotomy. In our naivety, we are led to believe that the two exist in mutual exclusivity. Since cities are human products, this belief is an overestimation of our own abilities and endurance. Richard Sennett wrote in Conscience of the Eye that cities are man’s attempt at mastery over nature. Indeed it is an attempt. Once a city is created, man’s superiority is never entirely in place and remains utopian, because urbanization is a continuous battle with ecological processes. The attempt at mastery is a sign of modernity. But as Marshall Berman explains in the classic All That is Solid Melts Into Air, the fact that destruction is always inherent to ‘the new’ is often overlooked. The tragedy of the modern hero in Faust comes “precisely from his desire to eliminate tragedy”. The same goes for architecture, which by nature promises progress, but in its creation already carries destruction. Not only of the structures and landscapes that existed before—it also holds the seed of its own destruction, either by socio-economic processes or by ecological forces.

nature in ruins by Tim Edensor (British Industrial Ruins)

USE OF ruins by Tim Edensor (British Industrial Ruins)

Walking through a ruin is to experience the collapse of boundaries in which the outside and the inside merge, and nature mingles with culture. The urban-rural dichotomy is violated by the invasion of flora and fauna into the previously ordered space of urban industrialism. In the city, nature is usually confined to the controlled spaces of parks and gardens and can only flourish in the cracks and unpoliced spaces. Factories are places in which raw nature, extracted from its environment, is then transformed into something else, but in the ruin, nature appears in less adulterated form. And plants and animals poisoned and persecuted by farmers are able to seek temporary refuge from an often equally intensively policed countryside.

Despite their position in the margins of the city, ruins are spaces where people can carry out activities without the surveillance of police or the increasingly ever-present CCTV cameras. Although we are warned to keep out because of unspecified danger, ruins accommodate a wealth of activities and are used as unofficial resources by city-dwellers.

As things fall apart, out of their remains emerge new forms of growth. Plenty of birds build their nests amongst the debris and in the formerly prohibited insides of buildings. Bats, rats and mice, as well as smaller insects and arachnids, colonise nooks and crannies, and butterflies and dragonflies flutter amongst the quick-growing shrubs such as buddlea, which settle rapidly on wasteground. Other invasive plants include rosebay willowherb, giant hogweed, rhodedendron, Japanese knotweed and Himalayan balsam, not to mention small birch and ash saplings. Mosses, lichens and fungus infest the damp interior spaces. Ruins thus provide opportunities for urban wildlife to prosper, creating oases of protection within the city.

... / description of opprtunities / ... The expanses of overgrown surroundings, previously well-pruned gardens and verges of factories, serve as realms in which plants can be grown, ranging from vegetables to cannabis. Outside the usual routes designated for pedestrians, there is also the chance to walk amongst un-manicured space, with dogs and other companions, whilst unregulated space can also be utilised for grazing horses and parking cars. Ruins are also places that because they are unused and slated for demolition, provide opportunities for pleasurable destruction and spectacular acts of vandalism (often called ‘mindless’). Moreover, ruins act as a storehouse for all sorts of useful materials that is free. Very often, shortly after buildings are abandoned, the informal lead merchants, scrap iron freelancers and stonemasons move in to rescue valuable stuff which can be sold on.

Liina Liis Pihu Tühjade aknaaukudega majad Kasutuseta hooneid on Eestis üsna palju ning see peegeldab ja põhjustab probleeme paljudes valdkondades. Mahajäetud hoonest saab tihti kodutute, narkomaanide või tegevuseta noorte kogunemispaik. Tühjade aknaaukudega majad mõjuvad moraalselt rusuvalt, majanduslikus mõttes väljendub see piirkonna kinnisvara hinna languses. Omavalitsusel või eraomanikul tuleb kulutada hulk raha trahvide maksmiseks, hoone sulgemiseks või konserveerimiseks, turvateenuse eest ja lõpuks energiakulukaks lammutamiseks. Kasutuseta hooned on mitmeti ohtlikud: varisemised, põlengud, mürgised hallitusseened jms. Inimeste püstitatud ning seejärel hüljatud objektid reostavad loodusmaastikku visuaalselt, aga ka füüsiliselt võimalike toksiliste ainete tõttu, mis olid kasutusel hoone ehitamise või selle kasutamise ajal. Peamiste kitsaskohtadena tuuakse välja kompetentse tööjõu puudumine olukorra kaardistamiseks ja juhtumite menetlemiseks, aga pole ka piisavalt raha, et hooned korrastada ja avad sulgeda või need lammutada. Riigikontroll soovitab kohalikel omavalitsustel esiteks kaardistada 2016. aasta jooksul nende territooriumil kasutuseta seisvad ohtlikud ehitised ning seejärel planeerida konkreetne tegevus ohu ennetamiseks, hindamiseks ja likvideerimiseks. Ohtlike hoonete järelevalve on suunatud tagajärgedele, mitte probleemi ennetamisele. Kasutuseta hooned ei pea kõik olema tingimata ohtlikud, kuid suur osa ohtlikest hoonetest on seda just seetõttu, et on jäänud tühjaks ja heaperemeheliku hooleta. Ennekõike tuleks vältida hoonete kasutusest väljalangemist. Üks võimalus hoida hooned kasutuses on vahekasutus: neile leitakse ajutine funktsioon kahe pikemaajalise (sihtotstarbelise) kasutuse vahepeal. Eestis vahekasutust uuriv ja propageeriv mittetulundusühing Ruumiringlus4 on püstitanud endale ülesande viia kokku tühi ruum, kasutajad ja tegevus. Riigikontrolli aruande järgi on paljuski puudujääke tühjade hoonete kaardistamises. Seega puudub teave, mille alusel saaks vahekasutust kavandada, ei ole tõest ülevaadet kasutuseta ruumidest, mida ettevõtlikele inimestele mingi funktsiooni täitmiseks pakkuda. Vahekasutus pole planeeritud teadliku tegevusena Eestis veel levinud nähtus, puuduvad tugistruktuur ning positiivsed näited. Raskusi ruumide ajutise kasutamise korral on ka juriidilistes küsimustes, näiteks puudub üürilepinguga sarnase ajutise kasutuse lepingu vorm jms.

ESSAY mid.presentation 13.10

REWILDING THE ABANDONED I would like to find „an Estonian way“ of dealing with abandoned spaces and work with local flora, maybe even fauna. For me nature is essential when creatng an „estonian space“. Here I beileve we could be one step ahead from the biggest megacities - we could bring nature back to the city before we destroy it totally. Besides green thinking, 0-energy building, reusing, reducing, recycling... rewilding the cities is becoming a new trend. Although „rewlding“ is generally used to refer to big-scale conservation efforts to protect, restore, and connect wilderness areas, rewilding is equally applicable to cities and surrounding natural areas. The notion can also be applied to nature uncontrollable overgrowing artificial spaces, in my field of intrest – spaces that are claimed to be useless. ABANDONMENT Estonian cityscapes are being developed as fast as left behind. After many different changes in administrative laws during the 20th century there is now over 102 totally abandoned villages in Estonia. People are moving to the bigger cities, Tallinn is growing continously. But even in the middle of Tallinn one can find abandoned spaces between restaurated or new buildings. There are numerous vacant houses in the centre of Tallinn that have been empty or will be staying empty for at least 5 more years, for example the ghost houses of Old Town, factory buildings in Rotermanni or Vineeri district and many other individual houses here and there. Ofcourse, at one point they will be renovated, but until that time these buildings represent just an unused emptiness in a valuable area. I wouldn't dig into the question why they are left unused processes happening after the abandonment, rather give the spaces a new (temporary) quality. WILDERNESS Either we see wilderness as a get-away from pressures of our fast-paced, industrialized society, a space where we can seek relief from the noise, haste, and crowds that too often confine us or is it a personal connection, every human being has a need for wilderness. Jaan Kaplinski: „Inimese instinktid sündisid suures osas metsikus maailmas – ebamäärasuses, kus igal hommikul ärgates tuli teha otsuseid vastavalt end ümbritsevale keskkonnale. Nüüd on meil kadunud selline vajadus, me oleme ise loonud endale süsteemi, teame igal hommikul ärgates, mis meid ees ootab ning teame isegi seda, kuidas veedame oma vanaduspõlve. Aga tegelikult me vajame sellist ebamäärast keskkonda, inimene on olend, kes tahab otsida ja avastada, aga tal pole enam aega või paikagi kus seda teha.“ Green cities and creating balanced combination between artificial and natural space is something that represents an ideal modern living environment. Building parks is a nice step towards that ideal but for me parks do not represent the typology of wild nature and are therefore fake nature. They are stricktly planned and trimmed and are just as artificial as the buildings around us. With my work I would like to rethink and create an alternative for the typology of an urban park.

THE COMBINATION Nature starts breaking the artificial space as soon as it is not maintained anymore. The spaces that are overgrown by nature and left for free usage, start to lose their initial built borders. The windows break, the walls become ruins, the plants grow indoors, the exterior-interior definition becomes questionable. A new life grows in, the notation abandonment becomes questionable. There is a certain beauty in decay. Nature intruding into a building creates a straight connection between landscape and interior architecture, therefore questiones the borders of these fields. Our sense of space has developed in wilderness without borders. Losing artificial borders encourages freedom of spatial interpretation and imagination. Building green areas is not in the field of interest of any real estate developers, because you can’t but a price tag to a square-meter of wilderness but you can sell a property with a high profit in the downtown area. Thatswhy I would like to connect the idea of urban wilderness and the unused buildings in densly built areas and temporary rewild the vacant houses until they will be restored for buisnesses and luxury appartments. The closed vacant spaces in densely built cityscape have the potential to improve our living environment if they would only be used differently – opened up to the public. And, for example, conrasting the artificial street fronts, filled with fast-growing ruderal plants, becoming temorary urban wilderness parks. I am also intrigued by learning from the nature and not working against it, building a artificial space that would initially become „wild“ itself by experimenting with biogradable and growing materials. I think that ruining processes keep the city alive. They shouldn’t be stopped, on the contrary - maybe even forced?

Casagrande laboratory - 3. gen city, paracity From Urban Acupuncture to the Third Generation City Marco Casagrande (2015) Published in “La ville rebelle. Démocratiser le projet urbain”, 2015 Gallimard ISBN : 9782072619564

The First generation city were the human settlements in straight connection with nature and dependent on nature. The fertile and rich Taipei Basin provided a fruitful environment for such a settlement. The rivers were full of fish and good for transportation, with the mountains protecting the farmed plains from the straightest hits of the frequent typhoons. The second generation city is the industrial city. Industrialism granted the citizens independence from nature - a mechanical environment could provide everything humans needed. Nature was seen as something unnecessary or as something hostile - it was walled away from the mechanical reality. The Third Generation City is the organic ruin of the industrial city, an open form, organic machine tied with Local Knowledge and self-organized community actions. The community gardens of Taipei are fragments of third generation urbanism when they exist together with the industrial surroundings. The Third Generation City is a city of cracks. The thin mechanical surface of the industrial city is shattered, and from these cracks emerge the new biourban growth which will ruin the second generation city. Human-industrial control is opened up in order for nature to step in. A ruin is when manmade has become part of nature. In the Third Generation City we aim in designing ruins. Third Generation City is true when the city recognizes its local knowledge* and allows itself to be part of nature.

Paracity is a biourban organism that is growing on the principles of Open Form: individual designbuilt actions generating spontaneous communicative reactions on the surrounding built human environment. This organic constructivist dialog leads to self-organized community structures, sustainable development and knowledge building. Open Form is close to the original Taiwanese ways of developing the self-organized and often “illegal” communities. These micro-urban settlements containe a high volume of Local Knowledge, which we believe will start composting in. Paracity, once the development of the community is in the hands of the citizens. The pilot project of the Paracity grows on an urban farming island of Danshui River, Taipei City. The island is located between the Zhongxing and Zhonxiao bridges and is around 1000 meters long and 300 meters wide. Paracity Taipei celebrates the original first generation Taipei urbanism with a high 12-level of “illegal” architecture, self-organized communities, urban farms, community gardens, urban nomads and constructive anarchy.

MY IDEA: In case of overgrowing the abandoned *Local Knowledge `= Genius Loci (of the precise place) means that the urban lanscape starts following the natural landscape that existed before the artificial space. For example: in a vacant building only the (ruderal) plants that were growing in this area before. When the abandoned spacehas overgrown toally, or decayed totally the pre-existing landscape is achived. The plants follow the logic of Genus Loci.

third generation city MORE RUINS - Phyllis Richardson Grandmothers, Academic Squatting, Urban Acupuncture-these are some of the ideas behind the Ruin Academy (see previous blog) in Taipei. Founded by Finnish architect Marco Casagrandeand a group of fellow researchers, as well as designers, journalists, academics to help guide Taipei through its journey to become a ‘Third Generation City’, the Ruin Academy is growing, as are its ambitions. When first generation cities refer to the development closest to the original nature of a site (‘dependent on nature’ or the natural terrain, one supposes), those that reflect rather than suppress or overcome the natural setting, Second Generation is where most cities are now, according to the Ruin Academy manifesto, overbuilt and largely disconnected from the inhabitants, as well as from the natural order of things. The Ruin Academy is a harbinger of Taipei’s status as a Third Generation city, one that is returning to its roots, so to speak. While some of the Academy’s positions might seem a bit radical, the idea that we need a new way of considering human beings and the built environment is certainly timely. As Casagrande points out, ‘Taipei has the highest number of 7-11 convenience stores in the world.’ That statistic alone, if accurate, should be enough to bring about a pause in the development frenzy. What are Third Generation cities? - Lee-Michael J. Pronko Third Generation cities are those that have grown from the ruin of industrial society but lie beyond its fordist structure of social and economic organization. Elements of Third Generation cities include:Anarchist Gardening (the spontaneous and nomadic construction of community gardens and urban farms that operate outside official urban development), Urban Acupuncture (the design of architecture that is placed in positions throughout the city in order to act as “needles” for producing and increasing the urban Qi), and River Urbanism (a form of landscape urbanism). Principally, Third Generation cities can be conceived of as rhizomatic in nature and ultimately, bound up with pre-existing and future conditions of human construction. Extracted from the website, “modernism is lost and the industrial machine will become organic. This happens in Taipei and this is what we study. Ruin Academy is an organic machine.” It would seem that it is the atrophy of the city that illumines the naature of the city and defines our age—what will we do with all of the buildings already built, considering by 2050 70% of the world’s population will be living in urban areas and “space” continues to become limited? In the end, it may not only be a matter of design or perspective in terms of how we look at the city, but what actions we take alongside the natural processes that unfold and transform the spaces we have inhabited, do inhabit, and will come to inhabit. It would seem that the collective space Ruin Academy has created may be just the right start for building, dwelling and thinking.

Zero City, Marco Casagrande

URBAN ACUPUNCTURE Urban Acupuncture is an urban environmentalism theory of Finnish architect Professor Marco Casagrande which combines urban design with traditional Chinese medical theory of acupuncture.[1] He developed his theory in Taipei after attending the Urban Flashes symposium before being invited back by the Taipei City Government to study the human/ organic layer of the city and how to react to it by means of urban planning. The focus was an illegal settlement, an urban farming community enclave inside the modern city named Treasure Hill. Marco Casagrande noticed this area was full of human energy that was being destroyed by the government. He states that the energy had been turned negative and had to be redirected positively towards construction, “like turning over the compost that has been the smelly part of the farm just to become the most fertile top soil. I was careful to manipulate these hidden energy flows and the small elements that I introduced to Treasure Hill can be compared to the needles in acupuncture.”[2] “Urban acupuncture is an architectural manipulation of the collective sensory intelligence. The city is a multi-dimensional organism with sensitive energies, a living natural environment whose points of contact - the energy flows beneath the visual city – are sought out by urban acupuncture. Both architecture and environmental art are in a position to produce the needles. A weed which plants its roots in the smallest crack in the asphalt can eventually ruin the city. Urban acupuncture is the weed and the acupuncture point is the crack. The ruin, a man-made process, returns to being part of nature.”

Case study: taiwan, taipei The busy and modern city of Taipei is home to a unique type of urban agriculture, not just for the purpose of producing and supplying agricultural products, but also for recreational, educational, social and environmental functions. Taipei, May 7 (CNA) New Taipei, Taiwan’s most populous city, is promoting urban farming amid its dense collection of residential buildings in a bid to encourage citizens to transform idle spaces on rooftops and in public areas into vegetable gardens.

TAIPEI Land use and buildings


Taipei City ranks above average in the land use and buildings category. The city’s population density of 9,800 people per square kilometre is above the Index average of 8,200 people per square kilometre.Given the limited availability of land, the conflict between land conservation and development is ongoing in Taipei City. But still the city manages to maintain more green spaces than the Index average, at 50 square metres per person. This is one of the highest rates in the Index, compared to the average of 39 square metres. City officials are conscious of the need for green spaces, and receive good marks in the Index for protecting them. Regarding eco-building standards, Taipei City has improved from the lax regulations during its early development in the 1960s and 1970s. The city now has strong policies on green standards for public buildings, incentives for households and businesses to lower energy use, and is promoting awareness of the value of energy efficiency in buildings. In addition, the authorities are encouraging neighborhoods to improve their local environment by providing engineers free of charge to create roof gardens and improve landscaping. Urban organic farming takes root in Taipei City (2013)

New Taipei promotes urban ‘community farms’ (2014) Taipei, May 7 (CNA) New Taipei, Taiwan’s most populous city, is promoting urban farming amid its dense collection of residential buildings in a bid to encourage citizens to transform idle spaces on rooftops and in public areas into vegetable gardens.

Mayor on Farm City Initiative: Roofs to Go Green Next Year Mayor Ko Wen-je reiterated that promoting Farm City is an essential part of his administration. Answering media questions on his objective of the Farm City initiative, Ko pointed out that the priority will be to promote “green roof” across schools, public institutions, and private buildings. He invited residents to visit the green roof booth at an expo slated to be held at Taipei Expo Park for more information at the end of the year.

Secret City: Illegal Architectural Interventions in Tawian “Beyond the ‘official city’ of Taipei, where modernization and beautification efforts are glossing over the city’s natural and historical origins, there is Instant City. Using Taipei’s conventional modern architecture as a platform and energy source, this network of illegal architecture attaches itself ‘like a parasite’ to create unsanctioned urban farms, night markets and other social gathering places.“ Marco Casagrande (2010)

The Community Gardens of Taipei The community gardens and urban farms of Taipei are astonishing. They pop up like mushrooms on the degenerated, neglected or sleeping areas of the city, which could be referred to as urban composts. These areas are operating outside the official urban control or the economic standard mechanisms. They are voids in the urban structure that suck in ad-hoc community actions and present a platform for anarchy through gardening. For the vitality of Taipei, the networks of the anarchist gardens seem to provide a positive social disorder; positive terrorism. They are tuning the industrial city towards the organic, towards accident and in this sense they are ruining the modern urbanism. They are punctual organic revolutions and the seeds of the Third Generation City, the organic ruin of the industrial city.
