Sash & Case Windows for Listed Buildings & Conservation Areas
Replacing windows on a listed building or within a conservation area can involve additional planning considerations and specialist requirements. We understand that navigating these requirements can feel complicated, which is why we work closely with a local architect to help make the process as straightforward and seamless as possible.
Our architect can assist with the relevant guidance, drawings and documentation for the Listed Building Consent process. This gives you complete piece of mind this is being handled for you.
Our role then continues through the design and manufacture of your windows. Every sash & case window is made specifically for your property, with careful attention given to the original proportions, astragal arrangement, profiles and traditional detailing.
From the initial survey through to manufacturing and installation, we work together to deliver a solution that respects the character of your property while providing the quality and performance you expect from a modern timber window.
