A larger ground floor and a new bedroom above for a growing family in Esher

This home in Esher needed more usable family space on the ground floor and an additional bedroom upstairs. We delivered a double storey extension that expanded the kitchen-diner and created a bright new room above, while keeping the architecture consistent with the existing property.

We coordinated drawings and approvals through planning permission, then ran a structured programme with clear milestones. Throughout the build we managed inspections and compliance via Building Regulations, and the day-to-day programme through dedicated project management.

What we did

Large extensions need strong coordination across structure, services and finishes. We planned for a clean handover and consistent quality throughout.

  • Programme planning, cost clarity and staging to reduce disruption.
  • Foundations, drainage adjustments and structural openings.
  • Superstructure, roof integration and weather-tight envelope.
  • First fix services coordination and second fix finishing.
  • Snagging, final inspection support and homeowner handover.

"We felt looked after throughout. The schedule was clear, the workmanship was strong and the new spaces have transformed how we live in the house."
