Florida-based firm Oppenheim Architecture + Design and Swiss studio Huesler Architekten have created offices for themselves in an eighteenth century building in northern Switzerland and constructed a new house in the garden behind (+ slideshow).

Located just outside Basel in Muttenz, the renovated building provides Oppenheim with a European studio and also contains a meeting room for the use of the local community.

New windows bring extra daylight into the white-washed offices on the upper storeys, which connect to the ground floor with a metal-framed spiral staircase.

The new timber-clad house is screened behind the existing building and has two storeys above ground as well as one below.

One side of the house is recessed at the back, creating a terrace that is framed by exposed structural columns.

Living rooms occupy the ground floor, while bedrooms are located on the floors above and below.

Here's some more text from Oppenheim Architecture + Design:

Kirchplatz Office/Residence

The design of this adaptive re-use project was born initially out of a design competition initiated by the City of Muttenz/Basel.

The design was based on the renovation of an historic farmhouse situated within the historic center core of the city.

The original farmhouse was constructed in 1743.

Today the converted farmhouse serves as an office for an architectural design company, provides community meeting space, and serves as a compelling link to a new, adjacent private residence.

The new design aimed to provide a fresh interpretation to the existing traditional features of the historic farmhouse building and it’s interior.

This is achieved by creating new openings for natural daylight and by using a crisp white finish in the interiors, which juxtapose against the texture of the old wood and through the way in which the spaces open up, overlap, and merge together with one another.

The sustainability considerations included maintaining an energy-efficient building through the use of current MINERGIE (energy efficiency) construction standards, solar roof panels, a sustainable choice of materials such as reclaimed wood used for the facade, and the restoration of existing architectural elements where possible.

The project also included the design of a new single family house adjacent to the adaptively re-used historic farmhouse that was converted into the office.

This elegant contemporary residential structure juxtaposes with the historic building.

The new and old share commonalities of materials and colors, yet have distinctly different expressions with the interplay of modern and historic delighting the senses.

The 3-floor house is organized with the master bedroom and guest bedroom on the top floor; the kitchen, dining and living spaces on the ground level; and the children’s bedrooms below ground with a ramped outdoor backyard terrace leading up to the ground level.
