BR7's mix of spacious Edwardian plots and modern developments creates diverse groundwork requirements. Clay soil conditions near Chislehurst Common can shift seasonally, making properly reinforced concrete bases essential. Many residents discover their seemingly level gardens hide significant slopes when planning shed installations.
Steel mesh reinforcement prevents cracking where tree roots from mature oaks proliferate. Proper drainage channels protect against water pooling, particularly crucial given the area's natural springs. Base depth calculations factor in both load requirements and the specific ground composition found throughout Mottingham borders.
Twenty-three years handling Chislehurst's quirky geology builds invaluable knowledge. Local planning considerations around conservation areas get addressed before breaking ground.

Standard 8x6ft shed bases range £450-650, whilst double garage foundations typically fall between £1,400-2,100 depending on access difficulties and ground preparation needs.
Absolutely - from Elmstead Woods to Petts Wood borders, covering all BR7 postcodes including properties backing onto Scadbury Park.
Site assessments usually happen within 48 hours, with concrete pouring scheduled 5-8 days later, weather permitting.
Each base carries decade-long structural integrity coverage, protecting against settlement, cracking or reinforcement failure under normal loading conditions.
Often feasible, though we'd need to assess current sub-base depth and composition - many older patios lack sufficient foundation for heavier structures like workshops.
