If you’re looking to preserve the charm of a period home while improving energy efficiency, this Accoya sash window renovation in Downs Park East, Henleaze offers the perfect inspiration.
Preserving Period Detail with Modern Performance
A distinctive home on this historic Henleaze street recently underwent a careful sash window renovation using Accoya timber, chosen for its exceptional durability and sustainability. The windows were bespoke-made to match the original design, featuring taller lower sashes and a unique 2-over-3 pane arrangement in the top sashes — a pattern shared by the entire street.

Subtle Renovation, Significant Results
