Response within 24 hours
Victorian properties around Garratt Lane often surprise people with their generous rear gardens. These plots, typically stretching 80-100 feet back, present incredible opportunities for contemporary garden buildings. Whether you're after a teenager's retreat, a creative studio, or accommodation for elderly relatives, the right annexe design can revolutionise your property without the upheaval of a traditional extension.
Planning permission in Wandsworth Borough follows specific guidelines for outbuildings. Most annexes under 2.5m height fall within permitted development rights, though proximity to boundaries and total garden coverage matter. Construction itself involves groundworks suited to London clay, insulated timber frames, and weatherproofing that handles everything from summer heatwaves to those unexpected April downpours. Modern annexes incorporate underfloor heating, triple glazing, and smart home technology as standard.
Local knowledge matters when navigating SW18's mix of conservation areas and standard residential zones. Years spent working across Earlsfield means understanding which designs complement Edwardian facades whilst maximising natural light from south-facing aspects.
