Performative house
13.04.2022
The performative house by the Edelaar Mosayebi Inderbitzin office will soon be ready for occupancy. Thanks to sliding and rotating components, high-quality living space is being created on a very small footprint at Stampfenbachstrasse in Zurich. Such solutions are highly interesting for us engineers.
The The average living space per person in multi-family dwellings has risen continuously since 1960, while the supply of available building land has been declining. is declining. The supply of affordable housing is particularly scarce in urban centers. scarce. According to the Swiss Federal Statistical Office (SFSO), more than half of all households in 2020 of households will live in an apartment with more than two rooms per person. In Zurich one third of the single households and one-third of couple households, and only one in one in three apartments is occupied by a family or a multi-person household. The architectural firm Edelaar Mosayebi Inderbitzin is tackling the question of how high-quality high-quality living space can be offered in a small area.

on a smaller footprint. There are several ideas for doing this. One approach, which has been
seen more and more frequently in recent years is the trend toward more shared spaces.
shared spaces. Another possibility is floor plans that can be
that can be flexibly changed. The performative house on
Stampfenbachstrasse in Zurich is a good example of this.
With With a cleverly placed revolving wall, the living space can be almost change in any way: Rooms can be divided, separated or connected. Revolving cabinets offer the same advantages as revolving walls and provide additional storage space. As a third performative element there are pedestals, which also divide the room and offer a lot of storage space with large drawers and floor flaps. storage space. The architects' goal is to create a living space that requires almost no additional furniture. additional furnishings.
Movable components such as sliding walls, folding walls or revolving doors are not popular in architecture, as they require more construction work and are susceptible to faults. constructional effort and the components are susceptible to malfunctions. malfunctions. The mock-up at ETH Zurich served to develop prototypes of such movable elements and to prototype and to refine them constructively. More about moving components can be found in the report on the research work " vacancy - no vacancy " by the office of Edelaar Mosayebi Inderbitzin.
Sound measurements
on the mock-up
The
floor slabs and walls of the performative house are largely constructed of
cross-laminated timber panels. The wood in the apartments is painted white
the wood structure remains visible. Thus, the construction is shown and
at the same time creates a pleasant and modern living atmosphere. The
cross-laminated timber walls are load-bearing and transfer large loads from the upper
floors to the floors below. So that in the area of the support on the
the floor slab, the wood is not compressed, so-called transverse
the loads are transmitted through a beech dowel with a diameter of 6 centimeters.
diameter of 6 centimeters.
There is still little experience with this new construction method today. Therefore, the architects and engineers decided to build a mock-up on a scale of 1:1. This mock-up was used in particular to check how these beech dowels behave in terms of sound and to what extent the sound is conducted from one apartment to the other. In this way, it was possible to determine that the legal requirements for sound insulation between the apartments were ensured. Due to the very noisy Stampfenbachstrasse, the requirements for the facade are high (De 39 dB). With an exterior wall made of cross-laminated timber and acoustically decoupled exterior insulation, which acts as a facing shell, these requirements can be met.
