The chalky slopes around Biggin Hill demand walls that work with the landscape, not against it. Stone walling here isn't just about boundaries – it's engineering that respects both gravity and groundwater.

Those steep gardens backing onto the North Downs present unique challenges for TN16 homeowners. Natural stone walls solve drainage issues whilst creating useable terraces from what was once an awkward slope. Many properties near the airfield struggle with exposed positions where timber fencing simply won't last – stone provides that windbreak without the maintenance headaches.
Building on chalk requires specific foundation techniques to prevent seasonal movement. Each wall starts with excavation down to stable ground, often deeper than expected due to the weathered chalk layer common across the area. Proper drainage channels behind retaining walls stop hydrostatic pressure building up during those wet winters. The right stone selection matters too – local ragstone weathers beautifully and complements the traditional Kent peg tiles seen throughout the village.
Twenty years constructing walls across the North Downs means understanding which techniques suit each plot's peculiarities. Local knowledge counts when you're dealing with everything from wartime concrete foundations to protected tree roots.

Dry stone walling typically runs £140-200 per square metre, whilst mortared walls range from £350-500 depending on stone choice and site access. A typical 15-metre boundary wall at 1.2m height might cost £6,300-9,000 complete.
Absolutely – from properties near the Churchill Theatre right through to the rural lanes towards Tatsfield. Regular projects include homes along Jail Lane and the steeper plots off Stock Hill.
Most residential retaining walls take 2-3 weeks from breaking ground to final coping stones. Weather and ground conditions can add a few days, particularly during winter months.
All structural walls carry a decade-long guarantee covering movement, mortar failure and stone degradation. This includes free annual inspections for the first two years to catch any settling issues early.
Stone matching involves sourcing from the same geological seam where possible. For older walls, reclaimed stone often provides the best colour match. We'll bring samples to site before starting any extension work.
