Client brief
On a secluded Surrey plot with its own woodland, lake, and former farmhouse, the owners set out to replace the old dwelling with a super-efficient, architect-designed family home. Key requirements were:
- All-electric, low-carbon heating and hot water.
- Unobtrusive technology that complemented the home’s minimalist aesthetic (including a new basement level).
- Consistently comfortable indoor temperatures and fresh air, with the lowest possible running costs.
