OFFICE 183

This project is adjacent to the Weekend House by OFFICE from 2009. The clients of the Weekend House purchased the neighbouring plot with an idea to make a guesthouse and move their dental practice there. The project is a simple box that combines the two functions. On the ground floor, radial walls of an inscribed circle define the rooms of the dental practice. A staircase in the corner, as well as the large central staircase in the garden, lead to the main double-height upper floor. The central space is empty, with all the side rooms, including kitchen and bathroom tucked between the circular space and the square perimeter. A mezzanine level above these side rooms is reached by a rolling library ladder. The niches between radial walls here serve as guest bedrooms, or depending on their depth, simply bookshelves. The building has a cross laminated timber structure and a facade entirely clad in aluminium perforated sheets. It sits at the street side of the elongated plot, leaving the remaining terrain to a garden and a garden shed at the far end. The openings on the facade reveal the distinction between the opaque cube and its hollow interior.
