Wimbledon's mix of clay soil and sloping gardens creates unique challenges for shed placement. Whether you're tucking a storage unit behind period properties near the Common or planning a substantial garden office in South Wimbledon, ground preparation makes all the difference. Local knowledge matters when dealing with mature tree roots and the drainage quirks common to this corner of Surrey.
Concrete bases typically measure 150mm thick, reinforced with steel mesh to handle seasonal ground movement. Proper membrane installation prevents moisture wicking through clay-heavy soil found beneath many SW20 gardens. Crushed stone sub-bases compensate for gradient issues, particularly crucial given how many local plots slope towards Beverley Brook. Each foundation includes integrated water runoff channels, essential for protecting timber structures during our notorious autumn downpours.

Most 8x6ft bases range between £450-650, though steeper gardens near Wimbledon Hill Road often push costs toward £800 due to additional levelling work. Larger 12x8ft workshop foundations typically sit around £950-1,200.

Site assessments usually happen within 48 hours, with excavation starting 5-7 days later. Complete base construction, including curing time, typically wraps up within two weeks of first contact.
Each foundation carries decade-long protection against structural failure, covering both concrete integrity and steel reinforcement. Documentation includes detailed specifications meeting British Standards, essential for any future insurance claims.
Old patios often need substantial work - most lack proper depth or reinforcement for permanent structures. Assessment includes checking sub-base quality, though salvaging existing slabs sometimes reduces overall costs by 20-30%.
