Those steep slopes behind Colliers Wood's period properties practically beg for timber sleeper solutions. From retaining walls to raised beds, quality hardwood transforms challenging terrain into stunning outdoor spaces.
Response within 24 hours
Colliers Wood's mix of compact Victorian plots and newer builds presents unique landscaping puzzles. Timber sleepers solve multiple problems at once - creating level tiers where gardens slope towards the Wandle, defining boundaries without blocking light, and adding architectural interest to otherwise flat spaces. Railway sleeper aesthetics particularly complement the area's industrial heritage near the old Merton Board Mills site.
Proper sleeper installation requires understanding soil conditions specific to this corner of SW19. Clay-heavy ground common between here and Mitcham needs adequate drainage behind retaining structures. Pressure-treated oak or tropical hardwoods resist moisture better than softwood alternatives, crucial given our proximity to the river. Each sleeper gets individually levelled and secured using galvanised fixings, preventing future movement as ground settles.
Twenty years working across South London means knowing which timber performs best in Colliers Wood's microclimate. Local projects span from Christchurch Road's terraced gardens to the newer developments near Tandem Way, each requiring tailored approaches.

Retaining walls using quality hardwood sleepers generally run £180-250 per linear metre installed. Raised planters start around £400, while full terrace systems for sloped gardens range £2,500-6,000 depending on height and complexity.
Absolutely - from Baltic Close to Cavendish Road, including all streets between Merton High Street and the Northern Line. Regular work extends into neighbouring Tooting and Wimbledon borders too.
Single raised beds take 1-2 days, retaining walls usually 3-5 days depending on length. Extensive terracing projects might need 7-10 working days, weather permitting.
All hardwood installations carry decade-long structural warranties. This covers settlement issues, fixing failures, and premature timber degradation - basically everything except deliberate damage or extreme weather events.
Yes, concrete sleeper replacement is straightforward. Timber offers warmer aesthetics and easier modification if you later want to add steps or integrate planting pockets. The swap usually takes 2-3 days for typical garden walls.
