Check the facts on the ‘Larger Home Extension Scheme’ for 2019

Updated: Jun 29, 2023

Perhaps you have been checking the 2019 housing prices outlook and are thinking about a new extension or renovation for the New Year instead. We, at Mint Builders are here to help and are offering FREE consultations through our newly re-launched 'Extend Instead' campaign.

Latest news on extensions indicates that if you’re planning on building a single storey rear extension under your permitted development rights, you have until 30 May 2019 to take advantage of a temporarily doubled size allowance under the Larger Home Extension Scheme. This includes extensions up to 8 metres (from 4 metres) for a detached house, and 6 metres (from 3 metres) for all other houses.

permitted development?

Permitted development as we have highlighted often on this blog is a type of pre-approved permission to build, which allows you to bypass the main planning process, providing your proposed designs fall within the government's guidelines.


You can still apply to your council for a lawful development certificate to prove your development is within the conditions provided, but, if your plans fall within the scheme, it can save time and potential complications over putting in a full planning application.

extra allowance

The key question is - does my single storey rear extension qualify under this opportunity? To take advantage of this extra allowance under permitted development, you’ll need to ensure your plans extend no more than eight metres (for a detached property) or 6 metres (for all other properties) from the rear elevation of the original house, as it stood on 1 July 1948 - which to be fair is a long time ago! You need to know this.


We at Mint can advise whether you are in step with this larger extension opportunity and we can help clarify matters and navigate you through a full understanding these rules - just ask, we’re here to help and ensure your 2019 extension plans can go forward as you want them to.

fully completed

In order to benefit from this Larger Extension option, your extension must be fully completed on or before 30 May 2019. You’ll need to notify the council in writing once your project is finished. Take note also that you'll need to leave up to 42 days for your application to be approved under the Neighbour Consultation Scheme, while sourcing surveyors and contractors also takes time, so you should start planning soon if you're interested in making the most of this increased allowance.


When submitting your home for the scheme, you will be required to provide in writing the date of your expected completion. Your local authority will then decide if this seems reasonable, if not, you might be excluded using this planning method.

missing out

If you do end up missing out on the Larger Home Extension Scheme, this isn’t the end of the world, of even your extension plans as you can simply go down the route of planning permission. We have the expertise to guide and help you all he way. Good luck for 2019 whatever your property extension or renovation plans. (Sourced information as highlighted on
