Those steep Victorian gardens throughout Streatham need proper groundwork foundations before any landscaping begins. From clay soil challenges to intricate drainage systems, getting the base right transforms everything that follows.
Response within 24 hours
Streatham's mix of period properties and modern developments creates fascinating groundwork puzzles. Clay-heavy soil near the Common shifts with every season, while the sloping terrain towards Streatham Hill demands clever engineering. Years of tackling these specific challenges means understanding exactly what works where – whether that's reinforced retaining walls for those characteristic tiered gardens or French drains to manage the water flow common in SW2's lower areas.
Proper excavation depth varies dramatically between Furzedown's sandy patches and the heavy London clay dominating SW16. Ground preparation starts with detailed soil analysis, followed by calculated excavation that accounts for frost lines and root systems from those mature plane trees lining many Streatham streets. Compaction layers get built up methodically, incorporating Type 1 MOT where needed, before any surface work even begins consideration.
Twenty years working these specific postcodes builds invaluable local knowledge. Every project draws on experience from similar properties nearby – understanding which solutions lasted and which didn't.

Most Victorian terrace gardens in SW16 range from £3,000-£8,000 depending on access difficulties and whether you're dealing with existing concrete that needs breaking out. Larger plots near Streatham Common might reach £12,000 if extensive levelling or retaining walls are involved.
Absolutely – from the conservation areas around Streatham Common station through to the newer developments near Furzedown. Regular projects span both SW16 and SW2, including those tricky rear access properties along Streatham High Road.
Typical Streatham gardens need 2-3 weeks for full groundwork completion, though those narrow Victorian plots with restricted access might extend to 4 weeks. Weather plays a huge role, especially during wet months when clay becomes unworkable.
All foundational work carries decade-long protection against settlement or structural failure. This covers retaining walls, drainage systems, and base preparations – essentially any element that supports what sits above it.
Definitely – Streatham's mature trees require careful planning. Hand digging within root zones, permeable surfaces to maintain water flow, and consultation with tree officers when needed all form part of the process. Those beautiful old oaks near the Common deserve proper respect.
