The chalky slopes and varied elevations throughout BR2 present unique opportunities for stone wall construction. Many properties here, particularly those backing onto Keston Common, benefit from retaining walls that manage dramatic level changes while preserving the semi-rural aesthetic. Local planning considerations often favour natural stone solutions over modern alternatives, making traditional walling techniques particularly relevant.
Building enduring stone walls requires understanding both geological conditions and structural engineering. Keston's mix of clay deposits and chalk demands specific foundation depths – typically 600mm minimum where frost heave poses risks. Proper drainage behind retaining walls prevents hydrostatic pressure buildup, crucial given the area's high water table near Fishponds Wood. Each stone placement follows centuries-old principles: two over one, one over two, ensuring stability without mortar in dry-stone applications.
Twenty years constructing walls across Keston has taught us which local stone weathers best against BR2's freeze-thaw cycles. Relationships with quarries in nearby Biggin Hill ensure consistent material quality that matches existing boundaries throughout Hayes and Farnborough.




Rated 4.9/5 from over 280 verified reviews
Dry stone boundary walls typically range £140-200 per square metre, while mortared retaining walls start around £250-350 per square metre. Properties near Keston Mark often require additional groundwork, potentially adding 15-20% to base costs.
Absolutely – from restoration work on period properties near Keston village centre to new builds around Locksbottom, we cover all of BR2 including the conservation areas where traditional methods are essential.
A 20-metre boundary wall usually takes 2-3 weeks, though retaining walls involving excavation and drainage might extend to 4-5 weeks depending on access and ground conditions.
Every wall carries decade-long protection against structural failure, covering foundation integrity and stone placement. This comprehensive guarantee reflects confidence in both craftsmanship and material selection specific to Keston's environmental conditions.
Restoration forms a significant part of our work – we carefully document existing construction methods, source matching stone (often Kentish ragstone), and replicate original pointing styles to maintain historical authenticity while meeting modern structural standards.
