Norbury's undulating terrain creates stunning garden vistas but challenging slopes. Whether your Victorian terrace backs onto Pollards Hill or your semi sits on Streatham's borders, engineered retaining walls unlock your garden's potential.

Those steep banks common to SW16's residential streets aren't just tricky to mow – they're wasted space. Properly constructed retaining walls transform unusable slopes into level tiers perfect for patios, planting beds or play areas. From compact Thornton Heath gardens to larger CR7 plots, structural landscaping changes everything about how you use outdoor space.
Modern retaining wall engineering goes far beyond stacking blocks. Drainage channels prevent water pressure buildup behind walls. Geotextile membranes stop soil migration through joints. Reinforced concrete footings anchor structures deep below frost lines. Each wall calculation factors in soil type, retained height, and surcharge loads from nearby structures.
Twenty years solving Norbury's trickiest garden levels means knowing which properties need planning permission and which don't. Local knowledge matters when navigating boundary walls near railway cuttings or managing slopes that affect multiple gardens along terraced streets.

Most residential projects range from £150-£350 per square metre of wall face. A typical 15-metre wall at 1.2m height might cost £2,700-£6,300 depending on access, materials chosen, and ground conditions.
Absolutely – from properties near Norbury station in SW16 through to homes around Thornton Heath pond in CR7. Regular projects include gardens backing onto the railway line and sloped plots throughout Pollards Hill.
Standard residential walls (10-20 metres) usually complete within 2-3 weeks including excavation and drainage. Larger terracing projects or walls requiring deep foundations might extend to 4-5 weeks.
Every structural wall includes decade-long protection covering both construction integrity and drainage performance. This comprehensive coverage reflects confidence in proper engineering – from foundation depth to coping stone placement.
Definitely – built-in drainage systems intercept groundwater flowing downhill, channeling it safely away through perforated pipes. This dual benefit creates level spaces while solving the soggy grass issues plaguing many sloped Norbury gardens.
