If you need to increase your living space but do not want to move then a well-executed house extension is a great way of adding both square footage and value to your property.

Coin Construction can manage your project from beginning to end. We take the stress out of the design and planning process, offering 3D modelling during the design stage, and we can also supply our preferred  kitchen designers and builders to complete the build should you wish. Our aim is to offer exceptional service and elegant design at a price that is realistic. You will be safe in the knowledge that you will be getting a wonderful extension and a stress free service at a surprisingly affordable price.

This leads us to the question that everyone wants to know 'What will it cost?" While specifications and designs can differ considerably we have put together a build cost guide to help you understand what to expect: What does an extension cost to build?



Changes to Planning Law introduced in 2008 mean that in most instances we can design your extension so that it falls within Permitted Development and as such will not require Planning Permission. However if your requirements mean that Planning Permission is required we are the people to get it for you.

If you would like to get a better understanding of what might or might not be possible then please feel free to get in touch.  We would be very happy to visit your home for a Home Consultation. Once we have seen your house we should be able to give you clear feedback as to what is and is not possible, as well as giving you some initial design advice and ideas. After the visit we will then send you a quote for the design and planning service allowing you to decide if you would like become the proud owner of a Coin Construction extension.
