Victorian properties throughout SE21 and SE22 often feature surprisingly deep plots that lend themselves beautifully to garden buildings. Creating additional living space without the upheaval of extending your main residence has become increasingly popular among Dulwich homeowners. The tree-lined streets and established gardens provide an ideal backdrop for contemporary annexes that complement rather than compete with period architecture.
Modern annexe construction goes far beyond basic summer houses. Insulated walls, double glazing, and underfloor heating transform these structures into year-round spaces. Planning regulations in Southwark typically allow structures up to 2.5 metres at the eaves when positioned within two metres of boundaries. Electrical connections, plumbing for en-suites, and high-speed internet cabling ensure your new space functions as seamlessly as any room in your main house.
Having completed numerous projects between Herne Hill and East Dulwich, understanding local planning nuances and neighbour considerations comes naturally. Each annexe reflects both the character of its setting and the specific needs of the household, from creative studios to independent living quarters.
