A garage and support spaces are located below grade in the addition with a large new kitchen and dining area on the main floor, and a library and offices above. The owner’s private book collection is accommodated in the new library with a mezzanine level accessed by two steel open stairs. The quantity of books required a system of double walls that slide to allow easy access to all shelves.

Two site specific interventions were done by the designers Kram/Weisshaar resulting in a LED installation in the indoor pool room as well as the ceiling of the entry hall where, throughout the day, the installation reflects the changes in the outdoor sky.

All of the public rooms are oriented to the south facing a large garden which was reconceived by landscape architects Wirtz International. Collaborating with Selldorf on the precinct around the building the area comprises a series of rectilinear paved and planted spaces including a swimming pool and reflecting water feature. These are in juxtaposition to the curvilinear and more expressionistic articulation of the larger landscape.
