Victorian and Edwardian properties throughout CR7 often feature surprisingly generous rear gardens, particularly along Brigstock Road and Parchmore Road. Many homeowners discover their 100-foot plot offers ample room for a substantial annexe without sacrificing outdoor enjoyment. The key lies in understanding local planning nuances and maximising every square metre intelligently.
Modern annexe construction has evolved beyond basic timber frames. Insulated panel systems create year-round comfort whilst steel-frame options suit sloping gardens common near Grangewood Park. Ground screws eliminate concrete foundations, protecting mature trees and reducing disruption. Each build incorporates mains electricity, optional plumbing, and thermal efficiency matching main residence standards.
Twenty years navigating Croydon's planning departments means anticipating potential hurdles before they arise. Local knowledge proves invaluable when positioning structures to maintain neighbourly relations across Thornton Heath's closely-packed streets.
