Planning Permission in Knebworth

Planning permission is a system where local authorities can authorise building works by granting permission for the planned work. Garage conversions will mostly not require planning permission, so long as the work is internal and you do not plan to enlarge the structure of your property. Garage conversions are often covered under permitted development rights, which cover a variety of home improvement work. However, these rights have been rescinded in a few regions by local authorities, particularly in new builds, therefore it is always worth verifying with your local authority. If you are preparing to undertake a garage conversion on a listed building or are in a conservation area, you will require planning permission. Furthermore, if the walls of your garage are shared walls with a neighbouring property, you will need a Party Wall Agreement. You are required to conform to all building regulations pertaining to your garage conversion whether or not you need planning permission. These building regulations cover elements of the conversion such as insulation, escape routes, fire proofing and ventilation, so it is generally a good idea to utilise an architect to draft plans and also to approve designs in order to ensure compliance with these regulations. You'll likely still need to submit plans detailing the change of use of the garage to your local authority. If planning permission is considered from the start of the project, it is much less likely that there will be any trouble further down the line. The majority of planning permission applications in England are approved.
