Those steep Purley gardens won't retain themselves. From the railway cutting slopes to Riddlesdown's chalky inclines, properly built stone walls transform challenging terrain into usable outdoor space.

Victorian properties throughout CR8 often feature original flint and brick walls that have weathered over a century. Today's stone walling techniques blend that traditional aesthetic with modern engineering principles. Whether you're tackling a sloping plot near Purley Oaks or creating defined spaces in Sanderstead's generous gardens, natural stone offers both structural integrity and timeless appeal.
Constructing retaining walls requires understanding soil pressure, drainage patterns, and load distribution - particularly crucial given Purley's mix of London clay and chalk deposits. Each stone gets individually selected and positioned, creating interlocking patterns that shift naturally with ground movement. Proper foundation depth varies between 450-600mm depending on wall height and local ground conditions. Behind every visible stone face lies carefully graded backfill and drainage channels preventing water buildup.
Twenty-three years building walls across South London's varied geology teaches you which approaches actually last. Local knowledge matters when you're dealing with everything from Kenley's exposed hilltops to Coulsdon's sheltered valleys.

Retaining walls generally run £180-250 per square metre including groundwork. Decorative boundary walls start around £150/m², while dry stone features range £200-300/m² depending on stone selection and complexity.
Regular projects span the entire CR8 postcode - from homes backing onto Purley Way playing fields to properties up near Riddlesdown Common. Also covering neighbouring Kenley, Coulsdon and Sanderstead areas.
Small boundary walls often complete within 5-7 working days. Substantial retaining structures typically require 2-3 weeks, accounting for foundation curing and weather delays.
All structural walls carry decade-long coverage against foundation failure or significant movement. Natural settling gets monitored during year one, with any adjustments handled promptly.
Absolutely - stone cladding transforms bland blockwork using stainless steel ties and breathable mortars. Popular for updating 1960s-80s properties throughout Purley where original walls remain structurally sound but aesthetically dated.
