The Roof

The Roof works a roof out the same way The Deck works out a terrace. Draw its faces on the same grid, set the pitch, and choose a covering — tile, slate or steel — and it lists the fixings and edge accessories underneath, priced from your own catalogue, on the editor and materials list The Bench already built for The Deck. In development: not yet open to try.
