Carlos Place in Mayfair, London, was originally developed by the Grosvenor family. Opulent number 14, also known as Mayfair House, was built by the Holloway Brothers in 1921 to the designs of Edmund Wimperis and William Begg Simpson.

The vast property has been refurbished and divided into six exquisite residences that capture the original style and detailing. We were commissioned by architects Derek Williams Ltd to design, supply and install 95 heritage sash windows, casement windows and doors, to closely match the original, yet deliver modern thermal insulation. We used approximately 890 individual slim double-glazed units for the project, all in oak frames.

Our heritage sash windows are based on Victorian box sash windows that work on the classic weight-and-pulley mechanism.

We can also provide single- or double-glazing with authentic-looking glass that allows the window to look traditional, but with the benefits of acoustic and thermal insulation.

Our casement windows can be designed to be inward or outward opening, side-hinged or top-hung based on your existing design or preference. Our casement windows retain the styling of this classical window design with traditional craftsmanship, but offer the benefits of modern technology and design.

Finally, our period doors provide the perfect complement by following the classic design of heritage French doors and single-timber doors that pay homage to these classic elements while providing increased security, insulation and longevity.

Our experience and commitment to authenticity ensures that our heritage sash windows can allow for flawless replacement for historical buildings, to allow them to benefit from modern energy efficiency.
