Those sloping Forest Hill gardens need proper foundations that won't shift. From compact Victorian plots to the larger gardens near Horniman Museum, getting the levels right matters.

Forest Hill's mixture of clay soil and London's unpredictable weather creates unique challenges for any permanent structure. Whether you're planning a garden office overlooking the South Circular or need a base for that long-overdue garage, the groundwork determines everything. Local knowledge counts when dealing with SE23's varied terrain and the occasional tree root from those mature oaks.
Proper excavation depth depends entirely on what's going above. A 100mm reinforced slab suits most garden sheds, whilst heavier structures demand 150mm minimum with steel mesh reinforcement. The curing process takes patience - rushing means cracks later. Ground preparation includes compacted hardcore, damp-proof membrane installation, then precise shuttering to achieve dead-level surfaces.
Twenty years working these streets means understanding which properties sit on old railway cuttings and where water naturally pools. Forest Hill residents value straightforward advice and transparent pricing - qualities that keep us busy from Perry Vale to Devonshire Road.

A single garage base (3m x 5m) generally ranges £1,200-£1,800, depending on access and ground conditions. Smaller shed bases start around £400, with most garden office foundations falling between £800-£1,200.
Absolutely - from Honor Oak station right through to Dulwich borders. Regular projects span the entire SE23 postcode, including those tricky sloped gardens near Forest Hill pools.
Most domestic bases take 2-3 days including excavation and pouring. Allow an extra week before placing heavy structures - concrete needs proper curing time.
Every base carries decade-long protection against structural failure. That means no sinking, no major cracking, no separation - just solid foundations you can trust.
Narrow Victorian side returns and basement access are common here. Concrete pumping equipment or wheelbarrow mixing allows us to reach even the most awkward Forest Hill gardens.
