Listed buildings and planning consent - we take the stress out of it

If you live in a listed building or conservation area, consent will almost certainly required for new windows, doors or conservatory.

Although most local authorities request that like for like, single-glazed replacements are installed (windows and doors), we have had approval for new double-glazing in certain properties.

Secondary glazing is an effective way of increasing thermal efficiency and noise reduction. In most cases secondary glazing will not require planning permission although we will always get this confirmed by your local authority prior to works commencing.

We are able to advise and take care of listed building applications upon your behalf including maps, elevation drawings (existing and proposed) and application paperwork.

Applications usually take between 6-8 weeks in order to gain approval.

Conservatories and planning applications

As a rule of thumb, approximately 60% of conservatories built will require planning permission.

Under the present legislation you may not require planning permission, providing you meet with the following conditions:
  • No more than 50% of the land which surrounds the "original house" can be developed. If you require a conservatory that covers more than 50% planning permission is required
  • If the proposed conservatory faces any road, planning permission will be required
  • Maximum depth for a conservatory on a detached property is 4 metres
  • Maximum depth for a conservatory on a semi detached property is 3 metres
  • The maximum height of a conservatory is 4 metres
  • Conservatories built to the side elevation of a property a maximum of 4 metres high and no more than 50% that of the original house
  • At least 50% of area that will form the external boundary / edge of the conservatory must be glazed and 75% of the roof area to be covered with either glass or polycarbonate (Building regulations)
  • All conservatories must be separated from the house by an external quality door, patio door or French doors (Building regulations).
  • Conservatories on listed building, national parks, Broads Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites will require planning permission
There are many more aspects that can affect conservatory planning issues such as product material and design.
