Do I Need Planning Permission for a Basement Conversion?

We take care of all compliance, council approvals, and Building Regulations to ensure a smooth process.

Refresh®’s process supports a bespoke design and build: a renovation tailored to your lifestyle requirements and taste. Your local Basement Conversion renovation consultant will manage every aspect for you - working to keep everything on track.

Step 1

Initial Consultation

The first thing your Basement Conversion renovation consultant will want to know is what it is that you want to achieve through your home renovation. In this initial consultation, you can throw all of your ideas on the table - your consultant will then tailor them to your property and budget.

Step 2

Scoping and Feasibility

With a clear understanding of your renovation goals, your Basement Conversion consultant can arrange for an architectural concept to be drawn up. This allows your Basement Conversion consultant to assess whether or not your ideas are feasible, and allows you to point out any changes you would like in the design - before any work begins.

Step 3

Detailed Planning and Costing

Next, working drawings will be developed. These will take into account the engineering, structural, design and aesthetic decisions you have made. If you would like to make any further changes, now is the time to do so. From there, your Basement Conversion consultant will present you with a fixed-quote as well as a contract.

Step 4

Build Stage

Finally, you get to witness your project transition from the page to your property! Every aspect of the build will be managed for you, allowing you to carry on with your everyday life. Your Basement Conversion consultant will do everything in their power to keep your project on schedule so that it can be completed within a set timeframe and budget.

Step 5

Project Completion

The final stage is for your local Basement Conversion consultant to ensure that all Council documentation is completed and you have the necessary Code of Compliance documentation. Congratulations – your renovation is complete!
