Planning 2009

The appearance of the district office in Calw is structured by vertically arranged ceramic elements in the façade renovation concept. The external impression of the building changes with increasing distance. Supported by the window bands, the façade structure appears horizontal.
The chosen colour tone connects the individual buildings of the district office and favours the effect of a uniform image.
Agilent extension

Gross capacity 32,000 m3
Gross floor area 5,250 m2
At the Waldbronn site, 21-arch was commissioned with general planning services for the extension and refurbishment of building 1, including outdoor facilities. In close coordination with the customer, new layout concepts were implemented in production, and new clean rooms were integrated into the redesigned production areas.
The conversion measures were divided into individual execution phases. Extensive protective measures enabled the work to be carried out without impairing production processes.
The facade in the area of the ground floor of the building extension consists of large glazed post-and-beam elements as well as claddings made of aluminium panels. The façade in the basement area is made of exposed concrete. The roof areas are extensively greened. After completion of the work on the extension building, the facade of building 1 was removed in order to create an extensive production area. The interior is characterised by bright and friendly workplaces. The extension building is seamlessly connected to the existing building 1, which is over 30 years old, so that both inside and outside an ensemble of old and new could be created.

As an energy supplier, the topics of customer orientation and sustainability were trend-setting for the design.
The striking solar sail, which covers the entrance area, lends the building an expressive gesture and is also considered a supplement to the energetically optimised building. A total of up to 100 kW peak solar power is generated by the photovoltaic system.

The dimensions of the new building communicate with the existing buildings and harmonise with the surrounding nature.
The differentiated use of administrative areas via open customer centre areas and a transparent, two-storey meeting room correspond with the different levels of the topography.
A glass walkway connects the new building with the existing structure.
Rathaus Gechingen
Planning 2008
Year of construction 2011
The appearance of the town hall in Gechingen is reduced to a clear building block in the façade refurbishment concept.
The implemented structure of the rear-ventilated curtain wall with fibre cement panels, with horizontal divisions in the area of the eaves and tapered cuts in the area of the gable ends, picks up on the layered structure of the surrounding shell limestone rock formations as a theme.
The windows inserted flush with the façade complete the new, closed cubature of the building.
