Garden annexes have become the smart solution for SW19 homeowners facing London's space squeeze. Behind the typical Edwardian properties along Christchurch Road, you'll find plots stretching 100 feet or more - ideal dimensions for a contemporary living space. Planning regulations in Merton have evolved to support these structures, making the process smoother than many expect. Local residents increasingly choose annexes over traditional extensions to preserve their main garden area.
Construction typically involves minimal disruption to your existing property. Modern SIPs panels create thermally efficient structures meeting current building regulations without months of traditional building work.
