You do not usually need to apply for planning permission for the insertion of new windows and doors that are of a similar appearance to those used in the construction of the house (note – a new bay window will be treated as an extension and may require permission).
However occasionally you may need to apply for planning permission if your council has made an Article 4 Direction withdrawing permitted development rights from your area. If you live in a listed building, you will need listed building consent for any significant works – internal or external, and this includes the installation of any patio doors.
If your house is in a designated area (conservation area, national park, area of outstanding natural beauty) there may also be additional restrictions in place. In all these cases, you are strongly advised to check with your local planning authority before carrying out any work. Planning Portal.
At Green Home Glazing our Chartered Architect director, Royal Institute of British Architects (RIBA), will advise you about all relevant planning requirements, will liaise with your local planning authority, and will obtain any necessary planning approvals on your behalf. (see GOAStudio London residential architecture).
The replacement or installation of new patio doors might require Building Regulations approval. Building Regulations relevant matters include the thermal performance of the glazed doors, safety glazing, ventilation, fire safety, and access. Planning Portal.
At Green Home Glazing we work with London Building Control Approved Inspectors to assess all the Building Regulations related issues for your project and offer certification for all door and window replacement and alterations.
If you are a leaseholder you may first need to get permission from your landlord or management company in addition to any other planning and Building Regulations approvals necessary.
Please ask your solicitor to review the terms of your lease in regards to how to approach your Freeholder and for advice on how to obtain the Freeholder approval. We will assist you by providing all plans and specifications your Freeholder needs to grant you the approval.
