Plot depths in Upper Norwood and Anerley frequently exceed expectations, presenting ideal opportunities for garden annexes. Local planning knowledge proves invaluable when navigating the specific requirements around Church Road's conservation areas. Crystal Palace's sloping terrain actually enhances annexe potential, creating naturally private spaces tucked away from main houses.
Insulated timber frames paired with contemporary glazing ensure year-round comfort without overwhelming utility bills. Foundations engineered for SE20's clay-heavy soil prevent seasonal movement issues. Smart layouts incorporate kitchenettes, bathrooms, and flexible living areas within compact footprints. Cedar cladding weathers beautifully against the mature trees common to Penge's residential streets.
Fifteen years navigating Crystal Palace's planning landscape means fewer surprises during applications. Long-standing relationships with local structural engineers familiar with Victorian property quirks streamline the entire process.
