That Victorian terrace garden in Norbury deserves a shed that stays put. Clay soil movement and those tricky sloping plots near Pollards Hill make proper foundations essential for any outdoor structure.
Response within 24 hours
Garden sheds wobble, doors jam, and floors rot without solid groundwork underneath. Norbury's mix of clay and London gravel presents particular challenges when creating level surfaces. Years of watching sheds sink into saturated ground during wet winters has taught us exactly which foundation methods work best between Thornton Heath and Streatham Common.
Concrete bases remain the gold standard for permanent structures, whilst eco-grid systems suit lighter buildings perfectly. Timber frame bases offer quick installation where access proves tight - common in those narrow side returns typical of SW16 properties. Each method requires precise levelling, proper drainage channels, and allowance for ground movement throughout seasonal changes.
Local knowledge matters when dealing with Norbury's variable ground conditions. Twenty years working these postcode areas means recognising problem spots before breaking ground, saving homeowners from costly remedial work later.

Most 8x6 concrete bases range £450-650 including materials and labour. Eco-bases typically cost £350-500, whilst timber frames start around £300. Final pricing depends on access difficulties and ground preparation needs.
Absolutely - from the Edwardian properties near Norbury Park through to newer developments in CR7. Regular projects span Thornton Heath, Pollards Hill, and throughout the SW16 area.
Concrete needs 48-72 hours before placing heavy structures. Eco-grid and timber systems accept immediate loading, making them ideal for urgent installations.
Every base carries decade-long structural warranty covering settlement, cracking, or movement issues. This includes free inspection after the first year to ensure everything remains perfectly level.
Narrow passages between terraced houses rarely defeat us. Materials can be mixed on-site or carried through in manageable sections. Even 600mm gaps prove workable with proper planning.
