Conservation Windows

Replacement windows are a necessary development and are in the best interest of the building. But, the windows need to meet the governing legislation’s criteria. Installing uPVC windows in a conservation area can jar with the heritage of the surrounding buildings and will be difficult to pass regulations. Our timber conservation windows fully comply with regulations and are carefully manufactured to blend in with the building’s natural charm.

Stunning Conservation Windows Make Replacement Easy

Our conservation windows are available in flush sash, casement or bay window designs to suit all property needs. They are available with bar designs to further retain the character of the property. While our conservation windows help maintain a traditional look, they feature modern advancements to make them functional. Our windows are double glazed, have great U-values and multi-point locking for increased security. Our conservation windows are made from high-quality timber, making them durable, low maintenance and long-lasting.

Whenever you want to make changes to a property in a conservation area you need to contact your local authority and check beforehand. Some conservation areas are flexible with home improvements but others may have strict planning permission requirements. Largely it will depend on what you are trying to achieve. Conservation areas are set up to protect areas of interest and are designed to retain the character and charm of the buildings in that area.

While modern extensions and features may be limited, replacement windows should be considered necessary to maintain the upkeep of the building. We can support you with your planning permission and design the windows to keep them as authentic as possible. Further information can be found here.
