That lovely new shed deserves proper foundations, especially with Biggin Hill's chalky soil and sloping gardens. Getting the base right means your garden building stays level for decades.

Most properties around TN16 sit on London clay or chalk, creating unique challenges for shed installations. Without proper groundwork, doors stick, floors crack, and the whole structure shifts within months. Local experience matters when preparing bases that cope with our specific ground conditions and drainage patterns.
Concrete bases need careful calculation of depth and reinforcement, particularly on the hillier plots near Aperfield. Timber frame bases suit level gardens but require precise joisting and weatherproofing. Ground screws work brilliantly on slopes, avoiding tons of concrete whilst providing rock-solid anchorage. Each method suits different garden layouts and budgets.
Twenty years preparing bases across Biggin Hill means understanding which properties need extra drainage, where tree roots cause problems. Regular work in Keston and Tatsfield keeps us familiar with local planning quirks too.
Rated 4.9/5 from over 280 verified reviews
Basic 6x4 timber bases start around £400, standard 8x6 concrete slabs £650-850, larger workshop bases £1,200 upwards depending on access and ground preparation needed.
Absolutely - from central Biggin Hill across to Westerham, down through Keston, all TN16 postcodes plus neighbouring areas within reasonable distance.
Weather permitting, most bases complete within 3-5 working days from start. Concrete needs 48 hours curing before shed installation.
Every base carries decade-long structural warranty covering settlement, cracking or movement. Documentation provided for insurance purposes.
Narrow side passages common in older Biggin Hill properties rarely pose problems - materials can be mixed on-site, frameworks assembled in sections. Even awkward corners behind Victorian terraces usually manageable.
