urban lofts, Berlin 2013

These two apartments are located in central Berlin, close to the river Spree in a very Berlin-specific building typology. The building was planned and used as a textile manufacturing site, yet the street facade does not convey the usage and is shaped similarly to a normal apartment block. The Holzmarkt Quarter, a former industrial zone is an up and coming district where many old industrial and storage buildings are converted to accommodate contemporary communities and live-work concepts. Both flats are designed, to allow this combination of living and working spaces; it was important to keep the sense of a large open space, so none of the dividing walls touch the ceiling, so that its typical late 19th century ceiling structure remains intact. Additional spaces (bathrooms, toilets, wardrobes) are carefully placed to produce more intimate spaces within the overall open area. Both flats have a basic rough asphalt -based terrazzo floor, similar in feel to its original intention - a textile producing company. Additional large 200 year old wooden planks are placed to give the spaces a warmer and cosy appearance.

This apartment building is located in a quiet neighbourhood in the south of Addis Ababa, Ethiopia, close to the International Bole airport. The client, a coffee producing company asked for a contemporary approach to solve the increasing difficulties in the rental market in AA for its employees; providing secure homes for employees, thirteen individually designed micro-apartments ranging 12 to 68 sqm were composed - all with papyros and endemic plant selected gardens, common water-saving washing facilities, a shared roof top with sports facilities, and shared parking. Extended back up systems for power+water cuts are provided, as water access is sporadic and - depending on the season can sometimes fail for several days; a thermal collector is placed on the roof top to allow for energy independent hot water during day and night. The electricity system is divided into “normal” and “safe” use, making sure 2 sockets, fridge and emergency lighting works in times of no / little access. Most external materials are locally produced, including recycled bricks from demolished houses, the interior cupboards, beds and furniture are designed and manufactured locally. Specific technical furniture ( lighting, kitchens and sanitary objects are imported to ensure quality and longevity. Design team: Julia Mauser, Brook Teklehaimanot, Mike W.

Bole, Addis Ababa, 2019-2022

Mayfair apartments, a G+12 apartment building in the center of Addis Ababa is a collaboration of investors aiming to provide unique apartment spaces for the modern family. Crowned with two penthouses, emergency staircases and any public space is used to make you move around and experience the city from different angles, heights and perspectives.

Each pot consists of double spheres, which are approximately 45 cm in diameter. The spherical geometry enables them to be stacked one on the other to compose a structurally stable assembly. The geometry of the pot minimizes contact between one another improving their contact to the atmospheric air, necessary for the cooling. The pots are connected by a rope woven on each pot: facilitating the assembly; ensuring its structural stability; and providing a water channel in between each pot. Six vertical layers of pots make a 2.4 high wall. Stacking the pots has multiple advantages: the wall will be easy to construct and because of its modularity, it can always grow. The top pots will be watered on a daily basis and gravity will enable the distribution of the water through the entire wall system in turn optimizing water usage.
