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"!
Granite Setts are incredibly hard wearing, making them a great choice for high traffic areas such as pathways like in this garden pathway design by Thorburn Landscapes. Nice design to use for narrow patio area outside french windows.
