Those sloping gardens typical of Streatham Hill present unique challenges when positioning outdoor buildings. Clay soil shifts, London rain pools, and uneven terrain can turn shed placement into a genuine headache. Professional base preparation tackles these issues head-on, creating level platforms that protect your investment from rot, subsidence, and that dreaded southwest London damp.
Ground preparation begins with accurate site assessment—checking drainage patterns, soil composition, and existing utilities running beneath SW16's older properties. Excavation depth varies between 150-300mm depending on ground conditions. Compacted hardcore forms the substrate, followed by either reinforced concrete or eco-friendly permeable paving systems. Each method suits different garden styles found throughout Streatham Common's diverse neighbourhoods.
Twenty years handling Streatham's challenging terrain means understanding which corners flood during autumn downpours and where tree roots threaten stability. Local knowledge matters when your shed sits year-round in unpredictable conditions.

Standard 8x6ft bases start around £450-600, while larger 12x10ft installations reach £800-1200. Sloping sites or poor drainage common near Streatham Common may add 15-20% for additional groundwork.
Absolutely—from Streatham Vale's spacious plots to the compact gardens backing onto Tooting Bec Common. Regular projects span SW16, SW2, and neighbouring Furzedown streets.
Most Streatham projects begin within 7-10 days of confirmation. Straightforward bases complete in one day, though challenging slopes might need 2-3 days including curing time.
Every installation carries decade-long structural assurance against settlement or cracking. This covers workmanship and materials, giving peace of mind through London's freeze-thaw cycles.
Sometimes—depends on slab thickness, joint stability, and whether they're truly level. Many Streatham properties have decorative paving unsuitable for weight bearing. Free assessment determines if reinforcement beats complete replacement.
