Those generous SE26 gardens deserve more than just lawn and patio. A thoughtfully designed annexe can unlock your property's potential while preserving that leafy Sydenham character locals cherish.
Response within 24 hours
Victorian and Edwardian homes throughout Sydenham often boast surprisingly deep plots - perfect annexe territory. Whether you're eyeing that unused corner beyond the shed or considering a full garden redesign, today's modular construction methods make adding independent living space remarkably straightforward. Local planning officers have become increasingly supportive of well-designed garden rooms that complement the area's architectural heritage.
Modern annexe construction bypasses most traditional building headaches. Steel-frame structures with insulated panels slot together in days, not months. Groundworks remain minimal - typically just concrete pad foundations that won't disturb mature trees or existing drainage. Everything arrives pre-wired and pre-plumbed, meaning your garden stays liveable throughout installation.
Sydenham homeowners trust our decade-long track record navigating Lewisham's planning maze. Each project starts with honest advice about what's achievable on your specific plot, not pushy sales tactics.
