Residential Extension & Conversion Applications: How to Transform Your Home
30 September 2025

Are you running out of space in your current property? Are you looking for a new property? Moving isn’t always the best option, especially with today’s rising house prices and moving costs. Instead, many homeowners are choosing to invest in their own properties through extension or conversion applications. From loft conversion to rear extension, it can give you the extra space you need while adding long-term value to your property.

Why apply for a home extension or conversion?

A house extension can completely transform your property. Here are the reasons:

  • Create extra space: Adding a new bedroom, home office or open-plan kitchen can create additional space within the existing home and avoids the stress and expense associated with moving.
  • Boost the property value: A well-designed extension or conversion can increase your home’s value.
  • Tailor made to adopt your lifestyle: Whether you need a gym room, modern workspace or larger open-plan kitchen, a bespoke design will perfectly fit your needs.
  • Save on the moving costs: Avoid stamp duty, legal fees and the stress of relocating by staying in your current home.

Do I need planning permission for an extension or conversion?

In some cases, a smaller project may fall under Permitted Development Rights. However, in most cases, the larger or complex extensions and conversions normally require either a prior approval application or householder planning application.. 

The Application Process:

Submitting a residential extension planning application typically involves:

  1. Design and drawings: Preparing detailed architectural drawings.
  2. Supporting documents: Preparing a Design & Access Statement with a description of  the proposed extension to support the application.
  3. Submission to local authority: Submitting drawings / plans and Design & Access Statement to the local planning authority via the planning portal.
  4. Approval process: Usually taking 8 weeks depending on the complexity.
