The two structures – one built from wood and the other from concrete, form a home office and a terrace for the property. The challenge was to create the new spaces behind the property, which opens out to a 144-square-metre yard. But the client placed a further condition on the build – that the garden had to remain as untouched as possible. The architects' response was to create two elevated spaces: an enclosed office made from glass and concrete, and a terrace covered in dark wood decking. The structures sit at opposite sides of the yard, with the office hoisted onto a wall above a corner patio and the terrace affixed to the original dwelling. The outdoor space that lies between creates a separation between home and work.
