Victorian properties throughout Catford often feature surprisingly generous rear gardens - a legacy of the area's suburban development. Converting part of this space into a modern annexe makes perfect sense when local house prices keep climbing. Many homeowners between Rushey Green and Catford Bridge discover their 100ft gardens can easily accommodate a stylish, insulated building without sacrificing outdoor enjoyment.
Planning permission for garden annexes follows specific guidelines in Lewisham borough. Structures under 2.5m height positioned 2m from boundaries typically fall under permitted development rights. Foundation work begins with a detailed site survey, accounting for mature trees common in SE6's established gardens. Modern SIPs construction ensures your annexe remains warm through winter whilst staying cool during those rare London heatwaves.
Having worked on properties from Bellingham borders to Catford Broadway, our team understands the unique challenges of SE6's sloping gardens and clay soil. Each project receives the same meticulous attention, whether it's navigating narrow Victorian side returns or preserving cherished planting schemes.
