Victorian terraces dominate Norbury's streets, yet their generous rear gardens hold untapped potential. A thoughtfully designed garden annexe can revolutionise how you use your outdoor space, whether you're near Norbury Station or tucked away in the quieter roads off London Road.

Space constraints in SW16 properties often mean families outgrow their homes long before they're ready to move. Garden annexes present an elegant solution, particularly given the typical 100-foot plots common around Pollards Hill and the wider CR7 area. These self-contained structures blend seamlessly with existing landscaping while adding valuable square footage exactly where you need it.
Modern construction techniques allow annexe installation without the upheaval of traditional extensions. Insulated timber frames, double-glazed windows, and weatherproof cladding create year-round comfort. Planning regulations in Croydon and Lambeth councils typically permit structures up to 2.5 metres at the eaves, meaning most Norbury gardens can accommodate a substantial annexe without formal permission.
Local knowledge matters when navigating the clay-heavy soil conditions between Thornton Heath and Streatham Common. Years spent working across South London means understanding drainage challenges and foundation requirements specific to this area.

Basic insulated structures start around £15,000, while fully-fitted annexes with electrics and plumbing typically range £25,000-£45,000 depending on size and specification. Properties near Norbury Park often opt for premium finishes, pushing budgets toward £60,000.
Regular projects span SW16 and CR7, extending throughout neighbouring areas including Mitcham, Tooting, and Crystal Palace. Most installations fall within a 5-mile radius of Norbury Station.
Groundwork and base preparation typically takes 3-5 days, followed by 2-3 weeks for the main build. Weather permitting, expect your annexe to be watertight within a month of starting.
Structural components carry decade-long protection against defects, while roofing and cladding warranties extend to 10 years. All electrical installations meet current Part P regulations with appropriate certification.
Absolutely - trenching along boundary walls allows discrete routing of power and water supplies. Many Norbury terraces already have external supplies for sheds or greenhouses, simplifying connections considerably.
