What You Need to Know
If you live in or own a listed building that has sash windows, there are a few things that you should know before you repair or replace them. Here’s your essential guide to listed building regulations and how they could affect any work that you have planned, along with the importance of working with a specialist in sash windows in North London.
Understanding Listed Buildings
A listed building is one that has special architectural or historic interest. All buildings built before 1700 which are still close to their original condition are listed, and most that were built between 1700 and 1840 are too. The criteria for a building to be listed have become tighter over time, and modern properties have to be very important to be listed.
Listed buildings are organised in three grades, which are as follows:
- Grade I: These buildings are of exceptional interest, sometimes internationally important.
- Grade II*: These buildings are particularly important buildings of more than special interest
- Grade II: These buildings are nationally important and of special interest. 92% of all listed buildings are Grade II.
Can You Alter a Listed Building?
Yes, you can! A lot of people assume that if a building is listed, that no changes and updates can be made to it. Rather, you just need to obtain listed building consent if you are going to make changes that could affect its special interest. If your building has sash windows, then it is likely that any changes to those will need to be approved before work can begin. This includes:
- Replacing the original sash windows
- Installing double glazing
- Changing the frame materials or colours
- Adding secondary glazing
It’s really important that you consult your local authority before you go ahead with any work, as failing to do so could see you made to return the building to its original condition – at your own expense!
The Importance of Working with a Trusted Team
If you are going to alter or replace the sash windows in your listed property, choosing a trusted team to carry out the work is vital. They will have a deep understanding of conservation laws and will be able to advise you on what kinds of work your local authority is likely to approve. Then, once approval has been granted, they will be able to work in full compliance with the criteria laid out, giving you peace of mind.
When you bring an experienced team in, you can count on high-quality craftsmanship and authentic materials, too. Joiners with experience working on listed buildings will have a solid knowledge of traditional techniques and materials, and will be able to combine this with modern innovations to give you windows that will stand the test of time.
What Now?
Making changes to sash windows in a listed building doesn’t have to be hard! By securing all the necessary permissions before work begins, you can preserve their charm and character while updating them to be more secure and energy efficient.
