Your Style,
Your Budget,
Our Expertise

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

Step 1

Initial Consultation

The first thing your House Extension 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 House Extension consultant can arrange for an architectural concept to be drawn up. This allows your House Extension 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 House Extension 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 House Extension 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 House Extension consultant to ensure that all Council documentation is completed and you have the necessary Code of Compliance documentation. Congratulations – your renovation is complete!

What size home extension can I build without planning permission?

As long as your extension qualifies under the prerequisites of permitted development rights then you can extend without permission. As an example, size restrictions and the keeping within of the existing finish of the property will apply for the addition of a single storey extension.

The specific conditions of permitted development will not apply if your property is a listed building. There is also a good chance that if you own a property in an area of natural beauty or conservation area that permitted development will not be applicable either.

Do home extensions add value to a property?

Additional living space is always eye-catching and will lure in potential buyers. It can no doubt be an attractive additional advantage when selling your home if it is built correctly. Unless it is built in proportion and mirrors the original builds quality then there is a risk of devaluing the property. This makes choosing your extension provider even more important. Statistically speaking, an asking price can increase by up to 11% if a property includes a professionally built two-storey extension. This of course, will require a larger budget and timeframe but could significantly increase value over time. 

How much will a home extension cost in West London? 

As with all estimates, the cost will fluctuate depending on the size of the property and the scale of the project. It is important to remember that the cost will ultimately be determined by the square footage required and you must factor in varying styles of fixtures and fittings in addition to VAT. A typical single-storey extension is usually around £2000 per square metre whereas a two-storey extension can be in the region of £3000 per square metre. Extensions which include bathrooms, kitchens or utility areas can be on the upper end of costings.
