Those Victorian terraces around Figges Marsh often surprise with their deep gardens - ideal territory for a thoughtfully positioned annexe. Whether you're accommodating elderly parents or creating rental income, the right design transforms unused lawn into valuable square footage. Local planning regulations have evolved too, making these projects more achievable than many Mitcham homeowners realise.
Ground conditions near Mitcham Common require careful foundation planning - the clay soil shifts seasonally. Modern insulation techniques ensure year-round comfort without hefty heating bills. Steel frame construction allows larger windows facing south, capturing light even during grey January afternoons. Every annexe includes full utilities: electrics, plumbing, and high-speed internet connectivity.
Twenty years navigating Merton Council's planning department means fewer surprises during your project. Previous clients from Colliers Wood to Cricket Green appreciate the transparent pricing and realistic timelines discussed upfront.
