Large House Extensions Made Permanent

Date: March 10, 2021

Good news for house extensions. The Government has recently introduced legislation to make previous temporary rights to enlarge a dwelling by up to 8 metres permanent. 

The Permitted Development Regulations have been amended to make permanent the right to enlarge dwellings by up to 8 metres in the case of a detached dwelling or by 6 metres in the case of any other type of dwelling as permitted development, subject to meeting the other relevant criteria for Permitted Development. 

Until the legislation was introduced, it had been necessary to complete any such extensions prior to the 30th of May 2019.

To benefit from these provisions, it is first necessary to submit a Prior Approval submission to the Local Authority, who will write to your immediate neighbours to advise them of your intended proposal. 

If any of your neighbours object, then the Local Authority is required to assess the impact of the proposal on the amenity of all neighbouring occupiers, not just those who have objected. 

The Local Authority is required to issue its determination within 42 days of the date of receipt of the application, and if they fail to do so, then you are automatically deemed to benefit from Prior Approval.

If you are interested in undertaking a house extension under Permitted Development, Hewitt&Carr Services can provide you with the necessary professional support in making Lawful Development Certificate and Prior Approval applications on your behalf.  If you’d like to discuss this further, please get in touch.
