Located across from the gardens of Buckingham Palace and a listed property, the renovation of No 1 Palace Street involved a retained façade. George Barnsdale were selected because of their specialism in providing windows and doors for retained facades projects, including The Lancasters (London) and 1 Grosvenor Square (London).
Working directly with the contractor Balfour Beatty Plc, George Barnsdale supplied and installed 282 timber windows and 181 timber doors over a lengthy and complex project which has seen changes in contractor and architect personnel along the way.
Both replication and acoustic performance were key to the design of the window and doors. Because the designs were so bespoke, the team at George Barnsdale carried out additional testing to ensure that their guaranteed performance wouldn’t be impacted by design tweaks.
The entire project consisted of a mix of around 270 Historic sliding sash windows, 10 dormer windows (3 of which are curved), 2 pivot windows, 179 inward opening tilt and turn doorsets (9 of which are curved) and two inward opening doorsets. Those windows at the front of the building had to be single glazed in order to meet the requirements of the Conservation Officer, whilst retaining high performance levels.
