Garden annexes have become the smart solution for SM6 homeowners seeking extra space without the upheaval of extensions. Whether you're converting that unused corner behind the rhododendrons or maximising the depth of a traditional Victorian plot, these self-contained structures blend seamlessly with Wallington's varied architectural landscape. Local planning attitudes have shifted favourably, particularly for properties backing onto the quieter residential streets between Roundshaw and Beddington.
Construction begins with groundworks suited to Wallington's clay-heavy soil, ensuring proper drainage channels that prevent the seasonal waterlogging common near Beddington Park. Insulated timber frames go up remarkably quickly - typically within days rather than weeks. Modern SIPs panels create year-round comfort while triple-glazed windows capture south-facing light. Each annexe incorporates power, heating and often plumbing, transforming forgotten garden corners into productive spaces.
Fifteen years of building across SM6 means understanding which designs complement Edwardian semis versus 1960s estates. Local knowledge matters when navigating Sutton Council's permitted development rules, especially near conservation boundaries.
