HOME EXTENSION PLANNING FAQ

Everything you need to know about Social Housing Investing

Do I need planning permission for my home extension?

Planning permission depends on the size and type of extension. Check local regulations or consult with a professional to determine if it's required.

What is Permitted Development?

Permitted Development allows certain types of extensions without the need for planning permission, provided they meet specific criteria.

What is a Lawful Development certificate?

A Lawful Development Certificate confirms that your extension is legal and doesn’t require planning permission, which can be helpful for future property sales.

What documents are needed for a planning application?

Typically, you’ll need a site plan, existing and proposed floor plans, elevations, sections, and possibly other detailed drawings.

How long does the planning permission process take?

The process usually takes around 8 weeks, but it can vary depending on the complexity of the project and the local authority.

Do I need Building Regulations approval?

Yes, most extensions require Building Regulations approval to ensure they meet safety and energy efficiency standards.

What are Building Regulations drawings?

These are detailed plans that show how your extension will comply with building regulations, including structural details, insulation, and fire safety measures.

What if I need design changes?

We include 3 rounds of unlimited design changes in every quote. These can be utilised at any point throughout the project, whether they are early tweaks or if the planners request changes.
