INTRODUCTION This academic year Unit 2 have focused on the development of a landmark for Worthing, a city that is currently going through an extensive regeneration. The aim was to explore the social and architectural issues related to high density housing and how high rise structures can affect local community and the architectural context of Worthing as a whole.

BRIEF The brief is to design a residential development at Worthing’s sea front. The aim is to propose 140 apartments within a 0.6ha site. The apartments are intended for over 55-year-old downsizers as well as starter and affordable homes. A requirement for 160 parking spaces including 60 spaces for public use has to be met. The brief seeks to propose 20 affordable apartments to the northeast corner of the site and 20 starter homes in the market block. In addition to the apartment requirements, a provision for residents amenities (bin stores, cycle stores, reception areas and stores) has to be considered.

The proposals should instigate spaces for creative industries as well as 600sqm of commercial units.

WORTHING Worthing is a large seaside town in England, with borough status in West Sussex. It is situated at the foot of the South Downs, 10 miles west of Brighton. With an estimated population of 104,600 and an area of 12.5 square miles the borough is the second largest component of the Brighton/Worthing/Littlehampton conurbation, which makes it part of the 15th most populous urban area in the United Kingdom.

The area around Worthing has been populated for at least 6,000 years and contains Britain’s greatest concentration of Stone Age flint mines, which are some of the earliest mines in Europe.

Worthing was a small mackerel fishing hamlet until in the late 18th century it developed into an elegant Georgian seaside resort and attracted the well-known and wealthy of the day. In the 19th and 20th centuries the area was one of Britain’s chief market gardening centres.

Modern Worthing has a large service industry, particularly in financial services. It has three theatres and one of Britain’s oldest cinemas. Writers Oscar Wilde and Harold Pinter lived and worked in the town.

Currently the site is occupied by a the former Aquarena swimming pool complex. The 0.6ha site fronts the Brighton Road to the north and Beach Parade to the south. The north-west corner of the site is occupied by Splashpoint Leisure Centre with a small civic space. The north-eastern edge of the site is occupied by an informal terrace of shops, currently the only retail spaces on the eastern end of the city centre. Sea front vistas are formed by two sides; Merton Road, at the east side and narrow ‘corridor’ touching directly against the Splashpoint Leisure Centre.

SITE HISTORY Worthing; the largest town in West Sussex is situated at the foot of South Downs between the sea and the hills. In the Middle Ages, Worthing settled as a small agricultural and fishing village. It’s development as a seaside resort began between the 18th and 19th centuries, developing into an elegant Regency town as known now.

The popularity of the town started to increase at the beginning of 19th century; attracting more visitors including well known novelists and future Kings. Worthing’s development continued throughout the 19th century. Expansion also continued northward and westward. The towns eastward development did not fully progress until after the Second World War; proneness to floods, combined with the development of industrial uses near the railway and westerly winds bringing fumes towards the east restricted any developments from taking place on the east side of the town.

DESIGN EVOLUTION The design evolution started with exploration of the tower and low rise/slab building forms and their position on site. I have studied various arrangements in plan and mass to understand the visual qualities that can be achieved within the given site.

High rise ‘marker’ to the north-west.

The idea was to create a visual marker with the use of a large tower building to the north-west of the site with the addition of low rise building to the south-west and south-east. I have looked for an appropriate balance between the height of the marker and the low rise buildings, with the respect and sensitive approach to context.

Further, I have looked at creating a public square that would act as a visual node between Brighton Road and the Promenade.

TOWER The tower design came from the study of Westkaai high rise residential project. The project designed by Tony Fretton Architect uses the principle of central core with 4 apartment units formed around it. This arrangements helps to distribute living spaces around the perimeter of the tower, allowing for dual aspect views.

My intention was to follow the same layout principle with the addition of a circulation 360 degree circulation space around the core.

At this stage the design lacked entrance lobbies that would separate the communal circulation with the apartment spaces.

EASTERN BLOCK

7 apartments per core

The idea for both the east and west blocks was to create narrow volumes that would allow every apartment to have views towards the street and the public square. With the benefit of oblique views towards the beach. I have studied a residential project by Gabriel Verd Architect which explores the same layout principles.

Through the design development of the low rise buildings I aimed to create an economic way of positioning cores within the overall mass. The intention was to design the ‘narrow’ layout in a way that would allow me to allocate 2-4 units per core.

Stage 2 - Working on duplex apartments with dual aspect facing street and public square.

Stage 4 - Resolving issues with ‘corner’ apartments.

Working on improving the previous corner layout with multiple single aspect units.

Stage 3 - Progressing development of dual aspect apartments within a narrow building mass. 2 apartments per core with the cores stacked next to each other.

Stage 5 - Improving the general arrangements.

Reducing the amount of cores and creating a communal corridor that wraps across the western facade facing the public square.

WESTERN BLOCK Initially the eastern block was formed as a slab building with 2 cores and a central corridor.

Apartment units were situated on each side of the corridor. This principle allowed for a large number of units to fit within a low building.

The challenge here was to reduce single aspect units to 0. and have a minimum of dual aspect.

In the process I have decided that the western block should follow the same principle as the eastern block to meet the requirements.

While the ‘narrow’ arrangement of these two blocks allows for a good quality apartments with multiple views, it creates an issue with the mass of the buildings. By reducing the width of the volumes, the buildings had to go higher.

Stage 1 - Arranging cores within the volume and exploring possible apartment positions. Single aspect issue was identified.

Stage 2 - Exploring the cores further and trying to rearrange the volume to reduce circulation space.

Stage 3 - Creating a long central corridor with 2 central cores. Exploring the impact on apartment locations

Stage 4 - Attempting to create apartment layouts within the previous arrangements. I was still facing the single aspect issue.

Stage 5 - Introducing external terrace around the internal perimeter.

Stage 5 - Exploring winter gardens and attempting to break down the terraces.

As the development progressed further, I decided to minimise the impact this created on the context by creating ziggurat volumes.

FACADE DEVELOPMENT The approach to the site was to improve existing and introduce new urban and seafront spaces.

The architectural intention was to create an appearance that would emphasize on the idea of a landmark. A landmark that would work in together with the existing character and appearance of Worthing, and its own individual context.

The simple idea of a public square surrounded by primitive geometry of proposed mass has influenced the quality of the faรงades. The proposal is designed to this language of simplicity of form and appearance.

The intention is to create a monolithic and flat appearance with sophisticated fenestrations.

LOCALE - RETAIL STRATEGY “The current quality of Worthing’s town center and seafront, existing retail and leisure offer, tourism attractions and visitor facilities and the quality of the environment, are all below the standard that Worthing deserves and aspires to. However, there is significant potential for positive and sustainable change to bring about the renaissance of Worthing as a vibrant town, with a more balanced mix of land uses, a stronger retail offer, economic and commercial growth, a more attractive seaside and leisure destination, and a cultural hub with strong education, arts and learning facilities” - Worthing Retail Core Development Plan

COMMERCIAL UNITS DEVELOPMENT

WORTHING RETAIL CONDITION Worthing is one of the most important shopping centers in West Sussex. The town’s retail function is extremely important in terms of both employment and attracting expenditure into the town.

However, in recent times Worthing has come under increasing pressure from its neighboring and competing centers such as Brighton, Chochester and Crawley where new retail developments are already being brought forward.

Proposed retail units within general massing

However, whilst the town suffers from a low quality primary retail offer, it does benefit from a relatively strong secondary and tertiary retail offer.

Warwick Street and Brighton Road offers a range of niche retailers that provide a specialist retail offer set within a distinctive historic environment.

This niche retail offer benefits from a number of cafe and bars, and is fast developing a cafe culture. Cafe culture and food and drink uses are an important ingredient in the overall mix of center.

Leisure activity encourages dwell time, which as a result helps to encourage additional spend and therefore in important in terms of viability for retailers. Food and drink uses add to the viability and vitality of a hub not just during the day but also into the evening.

Rents in Worthing for retail space have seen a steady increase in Prime Zone A’s since 2003.

As at mid 2007, local agents estimated prime Zone A rents in Worthing were at £115 per sq ft which represents no change on the end 2006 level. Rent in 2016 is expected to be an average of £130 per sq ft.

PROPOSED COMMERCIAL UNITS The intention is to provide commercial facilities that would fit within the immediate site context and not have a negative impact on existing shops and catering around the site. The proposed units start at the corner of Brighton Rd and Merton Rd creating a continuity of shops that already exist at Brighton Rd. Currently the area around the site feel detached from the town center in terms of retail and catering. Providing a number of smaller units would decrease that gap and increase the quality of the site and its context.

Interior atmosphere sketch studies

The proposed units would be leased at an average price as shown below. Worthing is significantly cheaper than London in monthly lease prices for commercial units. For example: a 160sqm unit in Worthing is £1600 compared to £2000-2500 in London.

Creating smaller units decreases the lease price and allows smaller businesses to establish their trade.

LOCALE - CREATIVE INDUSTRIES The East Beach Studios are located in one of three strips of beach chalets on the seafront.

Five chalets were originally converted in 2010, allowing local artists to work collaboratively in the public arena and grow their businesses.

Initially, the chalets were part of a two-year pilot project to see if this new use would be sustainable and have now become a part of the Active Beach Zone Attraction.

Their popularity has been not only with the artists’ community but also with the local residents & businesses and visitors to the area.

In 2013, the scheme expanded to 15 chalets (currently 12) with funds from WSCC Kick Start Programme which have allowed them to remain affordable today.

More than 50 artists and crafts people are on a waiting list, which has resulted in many studios being time-shared.

Activating the beach front further, a number of events are regularly organized, involving the local community creatively and ranging from book binding classes to art auctions.

Current Occupants:

The local authority has at this stage ceased plans to acquire the remaining chalets for conversion as many of the long standing tenants want to maintain their leases.

COLONADE HOUSE In 2014, the ‘Commit to Culture’ project was born following a successful application by Worthing Borough Council requesting Coastal Community funding to transform ‘Colonnade House’ into an Arts and Culture Hub. This resulted in the refurbishment of Colonnade House into a creative hub providing affordable workspace for predominately applied artists such as graphic designers, Illustrators, jewellery makers. The programme includes month long residencies and a ground floor gallery, creatively engaging with the community.

In October 2016, the first tenants moved in and the programme of events began.

The local authority continues to provide a small subsidy in support of the hub.

LOCALE - CREATIVE INDUSTRIES

CREATIVE INDUSTRIES DEVELOPMENT

The proposal of creative industries is a continuation of the creative realm created by East Beach Studios. The intention is to continue, expand and improve the creative characteristics of the area.

The proposal combines small artist workshops that could be rented and shared by various artists on a similar basis as East Beach Studios. In addition, these would also have an access to a gallery space that would allow the artist working within the site as well as at East Beach Studios to display and sale their work.

Part of the creative industries are artist quarters.

These work on a similar principle as Colonade House. Living/Working spaces are being rented out to artists. Communal living/dining spaces are part of the accommodation.

Workshops, gallery and the artist quarters are located at the south west of the site. The intention is to keep these activities closer the west to keep the creative continuity on the promenade.

ARTIST WORKSHOPS & GALLERY The artist workshops are 20sqm each allowing for a generous space for work, but also to display and sale work. The intention is to keep the workshops open to the public during the opening hours. Facing the public square, the creative industries add a quality to the space and increase the activity around and within the site. The gallery space can be accessed both from the promenade and from the square, connecting the two realms together.

TECHNICAL INFORMATION The intention was to test a building system for passive house with a cross laminated timber as structural element. Designing a tall wood structure becomes much more complicated at higher levels and additional construction is required. Whilst developing my design I have had a look at different methods of creating a hybrid building using CLT and steel.

The super structure of the building is made out of structural wood core and shear party walls (green) and steel perimeter columns (red) The use of structural party walls has proven to diminish some freedom in designing of my apartments, but these can also be placed accordingly to the design approach. The absence of structural external walls was beneficial for my design due to the large amount of fenestrations within the facade.

CLT is a massive wood construction element that consists of bonded single layer panels arranged at right angles to one another. These single boards are than compressed to form a panel. Panels are usually made up of 3-8 single layers and can range between 60-320mm thick. Maximum size achievable is 16m x 2.95m.

Single CLT panels are mechanically fixed together using self tapping screws and bolts. Each panel join is sealed and taped to achieve air tightness of the structure. CLT’s thermal performance is determined by its U-value, which relates to panel thickness.

Thicker panels have lower U-values. The use of cross laminated timber is efficient and allows for easy and quick construction.

Bay study of low rise building Scale: 1:60

75

WORKING DRAWINGS While working on the detail design, I have looked at different methods of using CLT within the construction. One of the methods was the use of Rib slab. Rib slab is a factory made structural component constructed of laminated veneer lumber panels and beams.

Potentially that method of construction seemed appropriate for the design, but further research proved that even though rib slab provides more flexibility for horizontal spread of services it its prone to deformation at higher loads/levels. Understanding the key construction elements of CLT was a key factor while developing the design and learning how certain connections can be achieved was explored.

This diagram explores the structural differences between the uninsulated cold space of winter garden and insulated space of an apartment. The biggest challenge was to achieve an airtight ‘secondary’ facade and avoiding any cold-bridging between the two spaces. I have attempted to achieve that by separating the winter garden slab from the main building structure and insulating any gaps between the two. Please see Detail 2.

WINTER GARDEN & CLIMATE CONTROL The plan design of the buildings allows for most of the apartments to have access to a winter garden. Integration of the winter garden within the envelope of the building, decrease the space heating demand of the apartments. In the autumn-winter period, a winter garden have a positive effect on energy balance, through so-called greenhouse effect. It acts as a thermal buffer using a natural source of energy - the sun’s rays.

Winter garden is an additional barrier against the winds from the north and reduces street noise coming to your house. In addition, built-in openable window at roof garden level helps natural ventilation in summer (the chimney effect). The winter gardens create a atmospheric balance between the apartments and the garden. The thermal conditions can be additionally controlled with the introduction of planting. During summer the water vapour from plants helps to keep the temperature within the garden lower than the outside temperature and thanks to open-able windows which provide ventilation.

POST CRITIQUE DEVELOPMENT PUBLIC SQUARE The final critique concluded with two main comments relating to my scheme. The first comment referred to the public space. It was noted to me that there is a large amount of space that is being unused which should be utilised by introducing more activity or an additional architectural element.

I responded to this comment by introducing 3 elements. A private residents garden; shared by all residents and accessible through a residents lounge. A public garden (as introduced in the scheme originally) This would be a public green space with an additional use as an outdoor exhibition space for the artists work.

The third element is an architectural object. I have explored two options:

eastern block

public garden

- Pergola; an external corridor that ties the green spaces together.

central pergola

- Coffee shop which sits beside the public garden, creating more activity around the square.

POST CRITIQUE DEVELOPMENT FACADE DESIGN After the critique I made a further attempt on improving the design of my faรงades. One of the comments made during the critique was to reduce the number of different sizes of windows and to make the fenestrations uniform.

I responded to the comment by exploring further arrangements of windows. I have looked at possible introduction of panels and bay windows.

The aim was to simplify the facade layout, but to also stick to the idea of chequered window arrangement.

simple grid with uniform openings.

while keeping to the simple grid. I have increased the size of the protrusions within facade..

large protrusion consists of a small glazing unit and a solid panel
