Do I Need Planning Permission for a Conservatory?

Planning Permission Posted on Fri, June 21, 2013 21:17:31

Do I Need Planning Permission for a Conservatory extension?

Quick answer: It depends on the proposed size, location within the site and the area you live – but they are NOT exempt from planning permission.

Firstly, if your Permitted Development Rights (PD Rights) have been removed then you WILL need Planning Permission no matter what.

You can check your PD Rights by contacting the Local Authority Planning Department.

Then, for a semi-detached property, if the conservatory or extension is single storey and at the rear of the property then you can develop up to a 3m projection OR 3m-6m with extended PD Right until 30th May 2016.

If located at the side of the property then if may be up to half the width of the existing/as built/original building.

It make no real difference to the planning process or PD Rights if the development is a Conservatory OR an extension.

IMPORTANT: Please make sure that a least 75% of the roof area is glazed and a minimum of 50% of the wall area is glazed otherwise Building Control will require an application, foundation and structural details, possible heat-loss/thermal calculations and this will also attract a Building Control inspection fee.

Further info can be found on the Planning Portal – Conservatory Guide

OR check out the Planning Portal – Animated Guide it’s great!

If you’re unsure then please do not hesitate to get in touch – Thanks

New Permitted Developement

Planning Permission Posted on Fri, June 21, 2013 20:24:47

I’m sure that you’ve heard the rumours about being able to build a domestic extension with a projection of up to 8m… Well, it’s TRUE!!

The revision of the new permitted development right mean that from 30th May 2013 until 30th May 2016 single storey domestic extensions located at the rear of the property may be up to 6m (if the property is terrace or semi-detached) or 8m (if the property is detached).

Unfortunately you just can’t go building anything ‘willy-nilly’ – there are a few restrictions:

1. Development must be drawn-up and architectural details submitted to the Local Authority (no fee other than site location plans)

2. The proposal will be subject to consultation – this means that your neighbours may object to the development.

The process, from the day of submission, should take approx. 42 days, however, approval is not guaranteed – so be careful to keep you grand designs realistic and in accordance with the PD Framework.

In addition to the above other conditions apply – information can be found on this Planning Guide for the larger home extensions.

As always, for further information please de not hesitate to contact me.
