Kent's chalky slopes and traditional ragstone have shaped Sevenoaks gardens for centuries. Today's stone walls blend that heritage with contemporary design, creating boundaries and features that complement everything from Victorian villas to modern developments.

Stone walling in Sevenoaks requires understanding both the local geology and the architectural character that defines this corner of Kent. Those distinctive ragstone walls you see throughout Otford and Kemsing aren't just decorative – they're practical solutions to the area's sloping terrain and clay-heavy soil. Working across TN13, TN14, and TN15, skilled stonemasons match materials to existing structures while addressing modern drainage and stability requirements.
Building on Sevenoaks' variable ground conditions demands specific foundation techniques, particularly near the Greensand Ridge where soil shifts seasonally. Proper drainage channels prevent water pooling behind walls, while careful stone selection ensures colour harmony with local buildings. Each wall incorporates expansion joints to handle temperature fluctuations, preventing the cracking that affects poorly constructed stonework throughout the North Downs.
Twenty years of working around Dunton Green's railway cottages and Sevenoaks' larger estates has taught us which techniques last. Local knowledge matters when matching century-old boundary walls or creating new features that won't look out of place beside established gardens.

Boundary walls typically range £180-300 per linear metre, depending on height and stone type. Retaining walls for Sevenoaks' sloped gardens start around £400 per square metre due to additional structural requirements. Feature walls or repairs to existing ragstone usually fall between £150-250 per square metre.
Yes, regular projects span from Dunton Green's Victorian terraces to Kemsing's rural properties. TN13 covers most central jobs, while TN14 includes Otford's conservation areas and TN15 extends to the more rural holdings where agricultural walls often need restoration.
A standard 20-metre boundary wall takes 2-3 weeks including foundations. Retaining walls or those requiring significant groundwork might extend to 4-5 weeks, particularly during wet periods when Sevenoaks clay becomes challenging.
All structural stone walling carries decade-long protection against settlement or construction faults. This covers both the stonework and foundations, essential given Sevenoaks' ground movement issues. Annual inspections help catch any developing problems early.
Absolutely – stone cladding transforms modern brick walls to complement period properties. Using mechanical fixings and breathable mortars, facing stones create authentic appearances while maintaining the brick wall's structural integrity. This approach works particularly well for properties near Sevenoaks' conservation areas where visual harmony matters.
