There are multiple benefits of adding a balcony to your property; the extra space, creating an outside area, and the value it adds. But, however desirable the addition of a balcony may be, taking the time to find out if you need planning permission is of great importance and could save you a lot of hassle further down the line.

Some balconies, like Juliet balconies, won’t normally require planning permission as they are classed as Permitted Development. A lot of other systems, such as verandas, additional decking areas and the use of a flat roofed area as leisure space, often will. No matter what you plan on adding to your property, always check with your local planning authority before carrying out any work.


We spoke to Graham Townsend of Planning Partnership Ltd. He gave us more of an insight into some of the restrictions you could face when considering installing a balcony or other such feature. He said:

‘The most relevant restrictions are under Class A of Schedule 2, Part 1 of the Town and Country Planning (General Permitted Development) (England) Order 2015, which states development is not permitted if:

A1. (e) the enlarged part of the dwellinghouse would extend beyond a wall which—

(i) forms the principal elevation of the original dwellinghouse; or

(ii) fronts a highway and forms a side elevation of the original dwellinghouse;

and under Class B (Additions etc. to the roof of a dwellinghouse)

B1 (e) it would consist of or include—

(i) the construction or provision of a veranda, balcony or raised platform.’


  • The effect on neighbours

  • Loss of light

  • Is the property listed or in a Conservation Area

  • Matching the property’s materials

  • Fall prevention

Graham went on to tell us that ‘There are other restrictions and conditions that apply to PD rights. Overall, if there is any balcony, veranda, raised decking area or a roof terrace over a flat roofed area being created then it is certainly appropriate to check very carefully whether planning permission is needed. The prospect of overlooking neighbouring properties, affecting the amenities of neighbours will be the main issue of concern.

‘Not every change or addition to a property will require planning permission. However, any works undertaken without the appropriate consent may be subject to enforcement action by the Local Planning Authority (LPA).

‘LPAs normally offer a pre-application enquiry service that will give an informal opinion as to whether or not a proposal requires permission or comes within the scope of permitted development rights. There is usually a charge for this.

‘Alternatively, a Lawful Development Certificate may be sought for proposed development. This is a legal document that will confirm or deny whether something may be done without planning permission being applied for. An LDC will attract a fee and will normally be prepared by a planning consultant or other professional advisor.’

You won’t only need to consider the type of balcony you are installing; in addition, you will also need to consider the building as well. For example, flats and listed buildings will require planning permission. Listed buildings will also require listed building consent.

It is always a good idea to speak to a professional before starting any project of this kind to make sure you have covered all grounds.
