Situated at the southern end of the site on a wide garden plot, Siva House will eventually sit alongside future landscape and public amenity space forming a green link to the evolving nature reserve and the biomedical campus at Addenbrooke's, further to the East.
The main single storey extension is designed to be constructed off-site from structural timber panels, known as CLT (Cross laminated timber). These will form the main structural walls and roof that afford the low profile design. The buildings form consists of linear masonry clad walls, punctuated by large panels of glazing or timber. South facing clad walls step to release a simple roof profile with chromed steel panels inset to reflect the landscape. Beyond the line of the existing rear elevation, the building plan steps inward to create a layered edge to the southern boundary. A masonry garden wall continues, stepping down along the boundary distinguishing the garden enclosure, while forming a future backdrop to the approved future landscaped embankment. The internal north and east facing elevations consist of glazing and vertical timber cladding to complement the future garden character.
