You can replace or double glaze sash windows in some listed buildings and conservation area properties, but the work needs careful consideration before anything is changed.
The permissions required will depend on the property, where it is located and the alterations you want to make.
For homeowners looking at listed building consent for sash windows in Edinburgh, finding out what applies to the property should therefore come before choosing new windows or glazing. Traditional sash and case windows are often an important part of a period building, which means their design, materials and existing condition can all influence what work is appropriate.
Can You Replace Sash Windows In A Listed Building?
Changes that affect the character of a listed building require listed building consent. Altering windows can fall within this requirement, so you should establish whether consent is needed before work begins.
At Hermitage Windows, we have extensive experience working with listed buildings and conservation areas and can assist homeowners with the consent process. We can prepare condition reports for individual windows, supported by photographs showing damaged or rotten timber, alongside drawings and specifications for proposed alterations.
The condition of the existing windows is an important part of deciding what happens next. Where original timber remains suitable for repair, retaining and restoring the existing windows may be appropriate. Windows affected by more extensive deterioration may require a different approach.
When replacement is suitable and the necessary approval has been obtained, traditional appearance can still be respected. Hermitage Windows manufactures sash and case windows with the original mouldings and dimensions replicated, helping new windows sit appropriately within a period property.
Can You Replace Sash Windows In An Edinburgh Conservation Area?
Living in a conservation area does not mean that sash windows can never be changed. There are, however, additional planning considerations because conservation areas are designated for their special architectural or historic interest.
Current City of Edinburgh Council rules mean some window alterations in conservation areas can take place without planning permission, depending on their position on the building. Changes to principal elevations and certain side elevations facing a road can be subject to prior approval instead.
As the requirements depend on the property and proposed work, it is worth checking before altering conservation sash windows in Edinburgh. The aim should be to find a solution that respects the character of the building while dealing properly with the condition of the windows.
Can Sash Windows In A Listed Building Be Restored?
Restoration is often worth exploring when original sash and case windows remain structurally suitable for repair.
Our sash and case window restoration work can include repairing or replacing damaged timber, dealing with broken panes or cracked putty, re-roping the sashes and installing draught-excluding brush strips. The work required will depend on the condition of each window.
Keeping timber protected also matters if original windows are to remain in good condition. Our sash and case window painting service uses a microporous paint system developed specifically for sash and case windows.
Can You Double Glaze Sash Windows In A Listed Building?
Double glazing may be possible, although permission and an appropriate specification need to be considered for the individual building. Homeowners should not assume that standard modern double glazing will automatically be acceptable for a historic property.
Hermitage Windows provides double glazing for sash and case windows in Edinburgh. Our process involves restoring the existing case and manufacturing new sashes with energy-efficient double glazing. The new sashes are installed within the existing case, with damaged timber repaired where required.
This approach can improve thermal performance and reduce draughts while allowing the traditional sash and case design to remain central to the appearance of the window.
What Is the Difference Between A Listed Building & A Conservation Area?
A listed building is individually recognised for its special architectural or historic interest. Alterations that affect its character are controlled through listed building consent.
A conservation area covers a wider location considered to have special architectural or historic interest. Different planning controls can apply to properties within that area, although an individual building inside it is not necessarily listed.
Edinburgh has many properties where these considerations are relevant, so checking the status of your home and the requirements for the proposed window work is an important first step.
Should You Restore, Replace Or Double Glaze Your Sash Windows?
The right approach depends on the condition and significance of the existing windows alongside what you want to achieve.
Original windows that remain in good condition may benefit from restoration and draught proofing. Double glazing may be considered where improved thermal performance is a priority and an appropriate upgrade can be agreed. Replacement may become suitable where the condition of the existing windows means retaining them is no longer practical.
Having the windows assessed by someone experienced with period properties can help establish which route is appropriate before committing to the work.
