Replacing Windows In Conservation Areas

A conservation area is an area of specific architectural or historical interest, the character or appearance of which is desirable to preserve or enhance.  Many towns, villages and cities rely on historic windows for much of their architectural impact and character. Poor quality, inappropriate, replacement windows can easily erode traditional features on historic buildings.  

If you happen to live within a conservation area there are certain constraints that a local planning authority may apply to your home.  This is commonly known as Article 4, when a planning authority applies to restrict development rights in a conservation area.  Often older, more traditional buildings are fitted with timber windows simply because timber tended to be the main material used many years ago. Over time this can present a number of problems including the increased chance of rot and the need to consistently restore and paint the windows in order to keep the elements out and the windows preserved and looking nice.  Whilst this can provide a good opportunity to refresh the paint colour there are also limitations on colour choices within heritage and conservation areas.  Quite often houses that are built alongside rivers or canals are often in conservation areas and can suffer because at times they are exposed to damper weather conditions and therefore more prone to rot.

So what choices are there if you happen to live in a conservation area? Replacement windows need planning approval and conservation area consent, this is quite rightly done to preserve architectural merit. Initially some planning authorities precluded the use of modern materials because the window designs were inappropriate in size, shape and design. Thankfully a more modern approach has been to approve the use of a product called Residence 9 because of its consideration of the Article 4 directives. Residence 9 has been specifically designed to replicate the documented historical window designs from the period.  The use of modern material should be accepted provided that the window is of design, dimensions, detailing and opening mechanisms are similar to the original window.

When it comes to listed buildings it is generally more difficult to replace windows in these buildings and approval must be obtained via English Heritage or Historic Scotland.  They are are the most important buildings in the town and are protected nationally with specific control over alterations, it is generally preferred to repair windows in listed buildings.

 

Replicate 19th Century Timber Window Designs With Modern Features And Benefits

The design brief for Residence 9 was to extract the key principles, shapes and dimensions from the Article 4 Conservation Area guidelines for windows, and integrate market leading technology into the design using virtually maintenance free materials. Residence 9 is thermally and acoustically brilliant. It features the latest security, maintenance and performance innovations, whilst appearing traditional. Your windows and doors won’t warp, swell, flake or need sanding and painting.

Authenticity And Energy Efficiency

Residence 9 has 9 chambers and is 100mm wide, resulting in superior thermal, acoustic, strength and security performance. It achieves a certified window energy A+ rating and accommodates the most thermally and acoustically efficient 44mm triple glazing and 28mm double glazing. Attaining U-values of 0.8 with triple glazing, PassivHaus Standard, and 1.2 with double glazing far surpassing the British Building Regulation requirements. All of this contributes to lower energy bills, keeping you cosy in the winter and cool in the summer.
