Those generous Sanderstead gardens deserve more than just lawn and borders. A thoughtfully designed annexe transforms unused space into something extraordinary – whether that's a teenager's retreat, home office, or granny flat tucked between the mature trees.

Sanderstead's leafy streets and substantial plots make it perfect for garden annexes. Many properties here sit on quarter-acre plots or larger, with that characteristic side access typical of 1930s suburban development. Building regulations in Croydon Borough have evolved considerably, and navigating the permitted development rights for your specific plot requires local knowledge. The sloping terrain common around Hamsey Green adds another layer of complexity that needs addressing from the outset.
Modern annexe construction has moved far beyond the glorified shed. Today's structures incorporate SIPs panels, triple glazing, and underfloor heating as standard. Ground conditions vary significantly between the clay soils near Purley Oaks and the chalk deposits closer to the downs. Foundation design adapts accordingly – sometimes a simple raft suffices, other times mini-piles prove necessary. Internal layouts maximise every square metre whilst maintaining that crucial sense of space and light.
Twenty years of building in South Croydon means knowing which planning officers appreciate contemporary design and which prefer traditional aesthetics. Local relationships matter when your project needs swift approval. Every annexe gets tailored to complement the main house, whether that's matching the red brick common in older Sanderstead properties or creating deliberate contrast with cedar cladding.

Most Sanderstead properties allow connection to existing utilities via armoured cables and insulated pipes. Separate meters remain optional unless you're planning future rental income. Distance from the main house influences costs more than connection method.
