High standards of workmanship for a fabulous extension

Rather than moving to a new house, changing what you have already is often the most practical option.  Building an extension can make an astonishing property transformation when done properly. It can even add value to your property.

From single storey to full wrap-around extensions, Jonathan Case Builders offers high standards of workmanship to create a fabulous conversion that complements your existing home. Whether you are creating an extension to add a couple of rooms, installing a staircase where there wasn’t one before, or increasing the size of an existing area to completely re-purpose the space, our skilled team provides superb attention to detail.

With years of experience, Jonathan Case Builders can advise on the best choice of methods and materials for your extension; from slate to sedum roofs; from aluminium bifolds to bespoke wooden windows. While we are adept at using modern construction techniques and eco products, we are also highly proficient in protecting and blending historical or special features.

We can manage the whole process from planning your project through to completion, including any plumbing, electrical and kitchen or bathroom installation, to ensure that your extension meets with your expectations.

If you are considering an extension, please contact us for a no-obligation site visit. We are happy to provide honest advice and talk through your requirements to help turn your ideas into a reality.
