The topography of the terrain, which slopes downwards towards Lake Hallwill, the desirable view and also the close proximity of the developed neighbourhood led to a compact building that is modulated in parallel to the slope’s contours. Its powerful formulation creates an identity-forming location within the quarter. The exterior appearance reflects its inner organisation, which zones the programme into different spatial layers. Special significance is given to the cross-sectional solutions, which are developed on the basis of a split-level typology and make an exciting spatial sequence tangible from the entrance hall on the slope side to the lakeside projections. The main levels are closely intertwined with each other, while the three storeys are gently interlaced. The section picks up on the theme of the slope and reveals a distinctive lighting guidance inside the building, which has an exterior of washed in-situ cast concrete.

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.
