The oldest still existent panorama painting in the world, the Thun Panorama, painted by Marquard Wocher between 1809 and 1814, was comprehensively renovated in 2014. The rotunda designed by the Thun City Architect Karl Keller in 1959, which has housed the panorama painting since the early 1960s, has also been renovated and enhanced by an annexe building. During this transformation, existing aspects of content, architecture and landscape were picked up on, reinterpreted and atmospherically condensed. The pavilion-like, transparent extension building, which transfers the circular geometry of the existing structures to gentle curves in the rectangular exhibition space, is like the antithesis of the introverted rotunda. Thanks to structurally similar characteristics, it enters into a quasi-symbiotic relationship with it, as old and new merge into an inextricable ensemble.

What began as a study 10 years ago can now finally be experienced as built spaces in Lucerne's Bramberg neighbourhood.
The slender, sculpturally modelled apartment building, which has replaced a dilapidated smaller residential building, makes use of the narrow plot in a densified manner, in keeping with the signed of our times but without creating a spatial constriction in the green neighbourhood structure.
The staggered volume and the customised flats inscribed in it thematise urban living through a variation of different flat types and well-proportioned, well-lit rooms. Generous windows and loggias open up views to the porous neighbourhood pattern, across the city of Lucerne and into the surrounding countryside with its hills, mountains and lakes.
In reference to the historic brick buildings specific to the neighbourhood, which rise upwards on existing garden-like plots, the new building has a vertically structured brick façade that subtly regulates views. The tectonics of the façade creates a lively interplay of light and shadow and makes principals of construction playful visible. While the pillars built on site are constructed in a horizontal masonry bond, the prefabricated parapet elements have a vertical, linear brick cladding.
