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"!
Garden bench built into rendered retaining wall. I like the way trees are also in the planter to create two layers, plus a narrow planting at foot of retaining wall and under garden seat. - Gardening And Patio
