This garden has zero threshold, a smooth transition from inside to out. We have linked to their new wooden floors and dark grey window, connecting and fusing the two, using a simple repeat palette of materials. We have incorporated a practical lift-up top to the bench to store their garden stuff. We have also included three re-circulating water blades that cascade into a dark grey pebble mulch. The lower area has been laid with astro turf, fitted to represent a carpet rather than a lawn. The oak sleepers, painted and matching the window frame, creating robust steps to the lower area, where we suspend a cantilevered bench from the boundary wall. We use very few plants - Dicksonia, Hosta, Polystichum and Buxus - an easy palette to maintain.
