Garden annexes have become the smart solution for SW17 homeowners facing London's space crunch. From compact studios tucked behind Edwardian semis near Tooting Bec Common to substantial guest suites in Furzedown's generous plots, each project reflects both the character of the property and the practicality modern families need. Local planning knowledge matters here – Wandsworth's particular requirements shape every design decision.
Construction starts with understanding your garden's unique conditions. Clay soil common across Tooting requires specific foundation approaches, while mature boundary walls often found in older properties can actually speed installation. Modern SIPs panels go up remarkably quickly, fully insulated and weatherproofed within weeks. Services run discreetly from your main property, with everything from underfloor heating to fibre broadband built into the structure itself.
Twenty years building across South London means knowing which planning officers prefer traditional cladding, where party wall agreements need extra attention, and how to maximise natural light without overlooking neighbours. Local suppliers, trusted groundwork teams, and established relationships with Wandsworth planning department translate into smoother projects.
