Explore the fusion of history and energy efficiency in London’s former residence of Sir Winston Churchill. Discover how vacuum glazed Georgian sash windows preserved the mansion’s charm while upgrading to modern standards.

Once the residence of the iconic Sir Winston Churchill, this magnificent mansion on the outskirts of Richmond Park in London exudes the elegance of an eighteenth-century period drama and has even graced the screens of the TV series ‘Downton Abbey’.

In the endeavour to restore this historic building to its former glory, a nine-year restoration project was embarked on to overhaul the entire estate, working closely with Historic England, conservation experts, designers, and craftsmen.

The challenge was to uphold the property’s historical authenticity while upgrading it to meet modern standards.

This involved the creation of Georgian sash windows using high-end vacuum glazing technology. The large Georgian sash windows, which characterise the impressive façade were central to this endeavour. They were beyond economic repair and the client was seeking sympathetic replacements and this is where vacuum glazing came in.

The project has gone on to earn national and international acclaim for the quality of the build.
