Hertfordshire Garden Wall Guide — Letchworth Garden City
Garden Wall Guide — Letchworth Garden City, Hertfordshire · SG6
How to design a garden wall that reads right on the street and stands up on local ground.
Most Letchworth Garden City garden walls we're asked to replace failed because the foundation was under-sized, the wall was built without piers on a run over 3m, or the coping shed water into the wall not off it.
Foundation and ground in Letchworth Garden City
Chalk and clay-with-flints underlie the town — generally sound but with variable depth on the original Garden City plots. A Letchworth Garden City garden wall needs a proper strip footing to the frost line — typically 450mm below ground, wider than the wall thickness — and reinforced across any known soft spot. Skip the trial hole and you'll be back rebuilding in five years.
Brick, mortar and design
Letchworth housing is dominated by Arts and Crafts cottages, Garden City semis and substantial Edwardian villas — soft brick, render, clay tile, often with original timber joinery owners want to retain. Choose the brick to match the closest wall on the street. On pre-1919 Letchworth Garden City property that usually means a lime-mortared soft red or stock; on interwar and post-war Letchworth Garden City property, a cement-mortared multi-stock. Piers every 3m on any wall over 900mm high, brick-on-edge or purpose-made cap on top.
Planning and boundary rules in Letchworth Garden City
The Heritage Foundation operate the Letchworth Garden City Scheme of Management on top of normal North Herts planning — every external alteration needs their approval as well, and they look hard at materials, detailing and roof line. Front walls in Letchworth Garden City up to 1m and rear walls up to 2m usually sit under Permitted Development, but Hertfordshire Conservation Areas, corner-plot sightlines and shared-boundary work all bring extra checks. The Party Wall Act applies if you're touching a shared boundary or excavating within 3m of a neighbour's foundation.
