The task of designing a new sorting hall for the recycling centre in Tännlimoos is exciting on a socio-political level: Processing, recycling and the gentle handling of cultivated land are important themes today. The form, placement and expression of the hall develop references on different levels to the locally typical drumlin landscape. The sculptural volumetrics of the free-standing building, with a ridge-like roof landscape, recalls geological formations. The gently modulated building silhouette, with its deep flanks, is nestled into the terrain and conceals the staggered height in a confidently relaxed way. At the same time, the form refers to the hall-like interior spaces and the definitive load-bearing system with its vertebral main girder. That creates a column-free hall, allowing ideally adaptable operative processes, also in future. The façade surfaces retain their natural colours and combine with the mossy rooftops to create reserved landscape motifs, without losing the refreshing directness of the industrial, modular building.

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.
