Concept
The land was previously used by a medium-sized steelwork company and has over the course of an
urban development conversion been redesigned into a new three-part mixed-use residential complex.
The front building is accessed from the road, the two rear buildings by a common courtyard. The fourstorey
linear buildings are aligned in a north/south parallel direction, allowing for optimal lighting in all
the rooms and terraces/loggias from east and west. A shared-use green courtyard as well as private
gardens, terraces, loggias and roof terraces give the outdoor grounds a generous and multifaceted
character.

Building distribution
There is a total of 48 apartments, 6 offices and 90 underground parking spaces as well as a commercial
surface area of 500m² with 16 allocated parking spaces.

Construction principle and materials
A traditional construction method featuring masonry, concrete ceilings, flat roof and a thermal insulation
façade has been used. By designing the ground floors to feature a colour-alternating slab façade and by
recessing the third floors, the first and second floors in each case join to form a white cube.

Energy concept
The apartments are classified as energy efficiency category B/B and are heated by a central gas
condensing boiler, supported by solar hot water. (in accordance with the building’s name SOLARIX)
