Those generous Victorian plots in Beckenham hold more potential than you might think. A thoughtfully designed garden annexe creates independent living space without sacrificing that leafy character the area's known for.
Response within 24 hours
Beckenham's mix of period properties and newer builds often share one thing – gardens spacious enough for something special. Creating a separate living space at the bottom of your garden makes perfect sense here, whether you're accommodating elderly parents or generating rental income. The tree-lined streets between Eden Park and Clock House have seen dozens of these transformations, each one tailored to complement the existing property.
Modern annexe construction goes far beyond the old prefab units. Today's buildings feature full insulation to Part L standards, underfloor heating systems, and triple-glazed windows that keep energy bills minimal year-round. Connection to your main house utilities runs underground, preserving garden aesthetics while providing mains electricity, water, and high-speed internet. Planning regulations in Bromley borough typically allow structures up to 30 square metres without formal permission, though larger builds remain achievable with the right approach.
Twenty years of working in SE20 and surrounding postcodes means understanding exactly what planning officers expect. Every annexe blends seamlessly with both your main property and the neighbourhood character that makes areas like Park Langley so distinctive.
