Many planning authorities reject the use of UPVC windows in homes in conservation areas and in listed buildings due to the cheap and unauthentic appearance. Windows play a crucial role in the visual aspect of a building, especially if they have remained intact for generations.

They are one of the most important design features. Even slight changes to the window can have a significant effect on the building’s appearance.  Evidence of craftsmanship and detailed design on old and rare materials are what makes historic windows of interest.

What are Conservation Areas?

A conservation area is a specific area with strict planning laws due to historic buildings with features that need to be preserved. The changes that can be made to existing buildings in these areas is limited and would require planning permission as the value of the properties and the visual aesthetics should be protected. It is an area of notable environmental or historical interest or importance, which is protected by law against undesirable changes.

How Does a Home in a Conservation Area Differ From a Listed Building?

A building in a conservation area requires permission to undertake anything that would alter its appearance from the outside. Its external appearance is protected.

When a home is a listed building however, the interior is also protected. The internal structure of the building must not be changed with any renovations or repairs using only original materials.

What is Article 4?

Buildings in conservation areas are protected under Article 4 as standard. If a building is covered by an Article 4 direction, then it requires planning permission when altering the facade (including windows and doors). Article 4 direction restricts changes that owners can make to the exterior of their property without planning permission in a bid to protect the special character or appearance of these conservation areas.
