About me My passion for the built environment started off at an early age working alongside my grandfather on a small scale church restoration project, spending summers on wooden roof reconstructions and learning to love the hands-on approach of the vernacular.

During my time at the TU Berlin I grew to love the moments between abstract and inclusive discussions and the material translation that follows it. Passionate and open-minded about new ways of transformative human-scale design.

Disappointment Enttäuschung An emotion study

Disappointment /ˌdɪsəˈpɔɪntm(ə)nt/ (noun) sadness or displeasure caused by the non-fulfilment of one’s hopes or expectations.

This emotional study was designed to deepen one’s understanding of the existing with the fictional. Split up between two semesters the students must design an architectural representation of a received emotion (pride, envy, sadness, happiness, etc.). This design must fit into an allotted 5 meter space inside of the architectural faculty building. In my case I had the opportunity of dissecting the emotional states of disappointment and attempting to translate them accurately to a 5 meter section of stairway. The second part of the case study would then be to translate the existing original concept into an otherworldly or said otherwise foreign contextualization where the materiality, functionality, and spatial language must be revised to fit the new.

Segmentation of Emotion

Defining the three stages of disappoinment

Translation into plan form

Change in perception

What makes up disappointment is correlated into space and time. The defining moment in perceptual change is when our understanding and prejudice of the moment is met with the relentless strength of reality. When our understandings are tested and we must adapt to the new or be crushed by it in a state of nostalgia.

Hand Drawings: Section 1:25, Plan 1:25, Axonometry 1:33

9 still sequences Model Photos, 1:25

The chosen design is constructively split into multiple wooden frames, dissecting the 5 meter span into 9 spatial fragments. The viewer / actor must tread upwards, not knowing what is behind the transfigured corner in the middle of the piece. This same middle is the epicenter of the emotional change and as such draws the eye towards it. Metaphorically the point of no return, where one must come to face reality and rise up to the new real.

The change in shape and form of the “average” and “mundane” rectangular frames follows the crushing, instant force of disappointment. This must not be taken as discouraging but as a test to which the final “balcony” (consisting of the last two frames) is horizontal, peaceful and calm.

Adapting itself to the outside the elements have now changed, the wooden frameworks steps aside and in its place, metal galvanized pipes are pre-bent and fitted into metal joinery tubes. The whole framework is now the leaning element, bent by the change in perception brought on by the impact of disappointment.

The verticality is no longer there, now flat on its’ side the architectural implementation is a platform for viewing the outside world, in this case the natural, wild flora of a outskirts of Hanoi City, Vietnam.

People are free to strow around with no break in sight, having their full attention set on the beauty of nature.

Bauhütte 4.0 New European Bauhaus

Part of the City Planning and Urbanization faculty the course covers the topic of Bauhütte 4.0 A research hub, centered around closed material cycles and using wood as a catalysator for urban transformation. Taking inspiration from Bauhaus, in the way in which concrete was introduced as the leading material of the future, used to construct many Weimar Republic settlements during the early 20th century, we take a similar approach this time with our attention focused on wood and timber solutions.

The project is part of New European Bauhaus and is to be used as a first-glance inspiration piece for the reuse of the old Tegel airport to construct a new Quartier, made entirely from renewable materials.

FOLLY “A structure, such as a pavilion in a garden, that is chiefly decorative rather than practical in purpose.”

To start off the project the task of constructing a FOLLY set was given. In the construction set there are two primary units: the first is a radial cut platform, the variations in this grouping is formed by adding additional 60 degree radial parts to the previous. Together they build a honeycomb. The second grouping of pieces consist of slat cuts with an indentation on the long sides to allow the aforementioned radial cuts to fit in snugly. The constructor was built with Balsa wood. See bellow images for construction reference.

Build Create

Live Concept With a modular grid, people are free to design their own space within their living quarters.

Therefore the idea of having a simple modular system was top priority, so that the buildings live on past their creation date: 5 , 10 , 15 years into the future, they should not remain the same. An openly accessible environment without ballast and unnecessary complexity.

9

Taking inspiration from the folly construction the principle of introducing wooden slabs and slats to modularly construct load-bearing walls was implemented together with the 60 degree rasterization of the floor plan. Using the two grouping units new interesting ground forms and niches are to be seen.

Scan this QR Code for an animation of the building construction.

10

The loadbearing walls are connected horizontally as well as vertically using dowel fits.

Each piece is 60 cm in height making them easy to handle during the construction phase. For the implementation of windows the same individual elements can be removed and a steel pane frame for the window can be introduced, removing their load bearing capabilities. The idea of keeping the construction set as simple as possible defines the small contrast between load and non-loadbearing walls.

Float 浮く: A place to rest Starting off our architectural journey during COVID-19 we had many challenges ahead of us but also opportunities. Our first design course will always hold a special place in my heart. The FGVANRIJS faculty had a most different context planned for us. During the semester we would have to research, cartograph and analyze the forested area around Müggelsee, Berlin. The GENIUS LOCI was empowered by a lake surrounded by marshlands and multiple wooden walkways on top of the water surface. For this project we took inspiration from the walkability and movement provided by these jetties.

Taking example from japanese tea ceremonial traditions we decided to provide a place to rest, in the mids of said movement - rethinking our connection to nature during the pandemic. Allowin g oneself to remove the every day and tedial and focus on truly and fully enjoying his surroundings. Combined with the stillness of January, the sense of floatability and ease was central in choosing our typology.

Course: Entwerfen + Baukonstruktion I Faculty: FGVANR Supervisor: Prof. Jacob van Rijs

The Tsukubai 蹲踞 (ceremonial wash basin) is positioned in the central circle platform of the structure.

Deconstructing the way of water, there is a clear symbolic relationship of spaces in ancient japanese tea ceremonies. First one must wait and change clothes in a waiting room. After the waiting room visitors use the Tsukubai 蹲踞 ( a traditional japanese wash basin). These spaces can be attached to the central tea ceremony building structure or be separate. They are meant to privide one with the time to disconnect from what was.

Second, one must walk the pathway littered with stones.The third position is the highlight this is where the tea ceremony takes place. It is often the most secluded part of the experience but line of sight is present with openings towards the garden.

The construction is kept light with hollow aluminum profiles and metal sheet roofing. Since the jetties are floating, a more conceptual approach was implemented - With air filled plastic canisters, similar to Christo’s Floating piers in Sulzano. The column and roof finish is kept minimal to act as a frame for what is happening around us. The natural landscape is the painting, the structure is the frame. For the waiting room and tea ceremony the walls are covered by a vertical greenery system so they blend into the moss covered shore.

Generation of waste, 2020

The Change, Reuse project sets its goals on redesigning the sanitation facilities of the BER airport.

The design tackles questions of sustainability and identity. Using a sustainable approach the decision was made to not look into the literal and established but to rethink sustainability in such a way that it is inherently at home in the city of Berlin. For that the decision to redo the verticals of the facilities made out of recycled building waste from culturally important buildings from Berlin’s past, that are scheduled for renovation. As more buildings are renovated, the project expands.

The identity of the facilities differs from one another based on the building its walls were constructed from - allowing for diversity in light, texture, color and feel.

Materiality

The floor plan has been reconfigured to expand on the number of stalls, sinks and urinals by multiplying them x2. A total of 16 toilets, 2 handicapped stalls, 8 urinals and 12 sinks. The circulation allows fast and straightforward crossing from the north passenger walkway and the south before-flight waiting area.

Interior Visualisation, right Hallway

For the walls a mixture of aggregate, sand, soil and concrete would be used as this material accounts for over 75% of all building waste generated. After being ground up to varying degrees of fineness these particles will be bound together by clay (Lehm).

Interior visualisation, facing opaque pane,’

The mens and womens toilets are separated by crushed up glass, sandwiched between 2 plexiglass layers. This allows both spaces to interact by letting light from the other side through but obstructing vision for privacy. The same is done for the plexiglass windows in the stalls facing north and south.

A part of Pankow, Berlin’s history, the building on the Wolfshagener street - the DDR serialized type C swimming hall enjoyed 40 years of service before falling into disrepair in early 2012. The project focuses on preserving the existing concrete structure and wave roof (Wellendach), introducing interactions between its’ program components and its two story typography. The main hall houses two swimming pools which overlook the southern street via a top-to-bottom glass curtain facade. We decided to give back to the community, which for multiple generations have been using the swimming pool as a place of daily refuge. By introducing new functionalities and parallel secondary structures we provide a shelter for kids and teenagers alike.

Course: Entwerfen + Baukonstruktion IV

The concept is influenced by the history of skating as a sport, focusing on using old derelict swimming pools, to which Alvar Aalto can be credited as introducing the skate bowl in the early 1930s. One man’s trash is another man’s treasure and skating encompasses this idea perfectly. The main pool is converted into a skate bowl having connections to the outside and to the basement via ramps. The small pool is preserved as is, divided by a colonnade and glass, and kept as a place of comfort and rest, providing a safe space for teenagers.
