Timber Sash Windows for Conservation Areas

Helping You Specify The Right Timber Sash Windows For Conservation-Sensitive Projects

Working Within A Conservation Area?

Being located within a conservation area doesn't automatically mean every replacement window must be an exact replica of the original. Planning requirements vary between local authorities and depend on the specific property, the existing windows and any planning conditions that apply.

​

That's why selecting the correct timber sash window system at the beginning of the project can save valuable time, unnecessary cost and avoid delays during planning. Whether you're renovating a period property, undertaking a self-build or replacing existing sash windows, understanding conservation requirements can be confusing. Our technical team helps builders, self-builders, architects and homeowners identify the most appropriate timber sash window specification before manufacturing begins.

Do You Need Heritage Windows?

Not necessarily. Many properties within conservation areas can successfully utilise our Classic Window System. Our technical team can help determine which specification is likely to be most appropriate for your project.

​

Heritage windows are typically reserved for:

Listed Buildings

Highly sensitive conservation projects

Properties requiring authentic historical replication
