Beginning with the technical processes of the spatial programme, a simple, but powerful typology is created with a timelessly archaic radiance and an openly designed system that can be flexibly used and extended to react to local conditions such as the linear landscape. The serially and successively sequenced operative layout is taken into account, as is the parallel operation of the two process lines, which are clearly aligned along a backbone-like central zone. Out of this «triple-winged» typology, a simple building structure of columns, girders and frames is developed. Set in a regular basic grid, the frame dimensions vary in depth and height depending on the required spatial conditions in individual segments. Through that variation, the structure directly forms the consecutive sections of the inner processes and binds them together through a regular rhythm. The resulting building silhouette appears to be in an oscillating, hovering condition between individual parts and the larger whole, which allows diversely legible scales for the facility.

We are delighted to announce that our team has won the competition for a residential and mixed-use building in the centre of the municipality of Horw, south of Lucerne.
As the competition motto JANUS suggests, our approach is characterized by a multifaceted compound that responds subtly to the given heterogeneous context. The urban boullevard in the north is addressed just as the park-like open space towards the south.
The staggered and porous structure leaves maximum green space and accommodates a variety of apartment types, collective rooms and commercial premises that contribute to a vital a tivation of the neighbourhood.
The simple and robust structural and spatial concept enables a long life span while leaving flexibility for future adaptation. The deep, verana-like facade layers act as a climate-sensitive treshold space and expands the interiors multifunctionally.
