We just wanted to say a big "thank-you" for the wonderful job you did on our first floor extension. We wouldn't hesitate to use you again and recommend you to our friends.

Interested in a house extension to add more rooms and extra space to your home?

It’s a cost-effective way to transform your property, and add value to your home if you eventually decide to sell.

With KCR Design, we’ll create formal plans for your new house extension which are based on your requirements and designed with industry-standard CAD software.

You’ll also receive a PDF version of the plans and two sets printed on A1 architectural paper with our large-format printer.

House extension plans which can be used for:

• Planning permission approval
• Building control regulations approval
• Builders’ quotes (instead of just estimates)
• The construction of the extension
