Streatham's mix of period terraces and interwar semis often come with surprisingly deep gardens. Many homeowners here discover their outdoor space stretches further than they realised. Creating a separate building at the garden's end has become the smart solution for families needing extra room without the upheaval of moving. From teenager retreats to rental opportunities, these structures adapt to whatever life throws your way.
Modern construction methods mean your annexe goes up faster than traditional extensions. Insulated panels slot together like sophisticated building blocks, while triple-glazed windows and underfloor heating create year-round comfort. Planning permission typically sails through when designs respect neighbouring sight lines - particularly important given how Streatham's sloping terrain affects garden levels. Each build gets tailored foundations to handle everything from London clay to the occasional Victorian rubble fill.
Twenty years of navigating Lambeth and Wandsworth planning departments gives us insight others lack. Local knowledge matters when you're dealing with conservation area boundaries near Streatham Common or the specific requirements around Furzedown's tree preservation orders.

Basic studio spaces start around £25,000, while fully-equipped one-bedroom annexes with bathroom and kitchenette typically range £45,000-£65,000. Luxury specifications or larger two-room designs can reach £80,000+, though still considerably less than extending your main house.
Absolutely - from the leafy streets near Tooting Bec Common across to Streatham Hill's period properties. Regular projects span both SW16 and SW2 postcodes, including the conservation zones around Streatham Common station.
Once groundwork begins, most single-room annexes take 4-6 weeks. Larger designs with plumbing might stretch to 8-10 weeks, depending on weather and any unexpected ground conditions - old air raid shelters occasionally surprise us in Streatham gardens!
