Banstead's generous Victorian and Edwardian plots often hide untapped potential beyond the main house. Creating a garden annexe here means working with mature trees, respecting sight lines from neighbouring properties, and understanding the local planning landscape. Whether you're tucked away near Nork recreation ground or overlooking the Downs, each plot presents unique opportunities for thoughtful annexe placement.
Building regulations for annexes in SM7 require careful navigation – particularly around height restrictions and proximity to boundaries. Modern construction methods mean your new space can achieve exceptional thermal efficiency, often outperforming the main house. Foundations must account for Banstead's clay-heavy soil, whilst clever design ensures year-round comfort without astronomical heating bills. Smart positioning captures natural light whilst maintaining privacy from adjacent properties.
Local knowledge matters when planning permissions can hinge on understanding Reigate & Banstead's specific policies. Years of successful projects across Banstead mean established relationships with planning officers and an instinct for what works in this area.

Absolutely – from the tree-lined roads near Banstead station to properties backing onto Epsom Downs, SM7 is our core operating area. Recent projects include sites in Nork and along the Tadworth borders.
Most Banstead garden annexes take 8-12 weeks from breaking ground to handover. Planning permission typically adds 8-10 weeks beforehand, though permitted development rights can fast-track suitable projects.
Each structure carries comprehensive 10-year protection covering the building envelope, internal systems and groundworks. This includes annual check-ups to ensure your annexe ages gracefully in Banstead's variable climate.
Most SM7 properties can extend utilities to a garden annexe, though Victorian houses sometimes need service upgrades. We coordinate with trusted local contractors who understand the quirks of Banstead's older infrastructure.
