Do I Need Planning Permission For My House Extension?

Most dwellings will have permitted development rights intact. This means that, subject to the proposed works, it is often possible to design and build a house extension without the need for full planning permission. Where works would be classed as permitted development, we would apply for an application for a “lawful development certificate” on your behalf. This provides you with written verification from the council that the proposal is lawful.

Generally, a house extension will require planning consent if:

  • More than 50% of the curtilage of the property is covered – note that previous extensions, detached garages, sheds etc. must be taken into consideration
  • The height of the extension exceeds that of the original dwelling
  • The height of the eaves exceed that of the original dwelling
  • The house extension is to the front of the property (or side of the property to corner plots)
  • The house extension is to the rear of the property and exceeds more than 6m projection for semi-detached or terraced dwellings, and 8m for detached dwellings (notwithstanding the above Notification for Prior Approval guidelines). Single storey rear extensions should be no higher than 4m to the top of the roof from adjoining ground level
  • The house extension is within 2m of the boundary, and the eaves more than 3m high
  • The house extension is to the side of the property, and more than 4m high, or has more than 1 storey, or is more than half the width of the original property
  • Materials to be used on a project should, where possible, match the existing dwelling. Where this is not the case, planning consent may be required
  • Two storey rear house extensions can sometimes be permitted development, provided that they do not project more than 3m from the original rear wall of the dwelling, and should be no less than 7m from the opposite boundary.

When determining the width or depth of a proposed house extension, it is important to consider the original building, as existing extensions will need to be taken into consideration.

House Extension Quote

One of the most important questions you’ll have at the beginning of your project, is what the cost of the project will be. As each extension we take on is entirely bespoke and dependent on the space and individual design work, we can provide you with a customised quote suitable for your requirements. Just get in touch with our house extension specialists to find out more.

We also offer construction-only packages if you have already arranged drawings by an independent architect. In this scenario, our house extension team will still offer you a fully project managed and guaranteed package, and can assist with 1st fix (structural only extensions) where needed.

Will I need planning permission for a house extension?
Before beginning a house extension project, it is essential that you speak to your local authority’s planning department to find out what is possible for your property. Depending on the size and scope of your project, your extension may fall within permitted development, and all you will need is a ‘lawful development certificate’ which Bigger Homes can apply for on your behalf.

If permitted development rights have been removed from your property, or if the proposed works fall outside of these regulations, then you may require full planning permission which we also take care of.

How much does it cost?
The cost of a house extension will depend on a range of factors including:

• The size of the proposed extension
• Whether it is a single or double-storey extension
• The position of the extension in relation to the remainder of your home
• The purpose of your extension, for example if you also need a new kitchen to be fitted
• Your individual finish preferences

Bigger Homes can explore a variety of options for your extension and will work with your budget requirements. We can modify your quote as necessary until you are 100% with the final proposal.

Would a house extension add value to a property?
Yes, adding any type of extra space to your home will undoubtedly increase the value of your property, not only in terms of its resell value but also the benefit to your lifestyle too.

It is difficult to put an exact figure value that an extension could make to your individual property. However, a recent Zopa survey of 1,000 homeowners found that an average extension costing £19,750 would generate a profit of £14,000 from the works. A similar survey conducted by Nationwide found that a double bedroom and en-suite added onto a three-bedroom home could boost the value of the property by 23%.
