To overcome the waterproofing issues that come with having an internal courtyard, a hob was created around the perimeter and a new slab was constructed that drains water out to a central storm-water pit. The raised hob and slab are disguised by a new recycled timber deck that straddles the interior and exterior spaces, blurring the transition between the indoor and outdoor areas. Movable planter boxes made out of Cor-Ten steel were introduced to create a garden.
