Holy moly – the glass see-through bit! Reminds me of the house/cabin we stayed in in North Carolina overlooked the wine cellar. House with roof terrace and underground kitchen (Thatcher's old house, redeveloped in Chester Square, Belgravia)
Belgravia House in London by Todhunter Earle. Even though this is a rooftop garden, the design show would be excellent for any long, narrow yard. Great way to break up the space by making different "zones"!
