Our Services

Whatever your building requirements, Cornerstone has the experience, knowledge and people to make your vision a reality.

New Build

With a number of new build projects successfully completed, we are ideally placed to not only deliver the building you want on time and on budget, but to assist with the less obvious issues involved in a larger project, such as NHBC certification and more complicated planning issues. We can offer full project management if required.


An extension can completely transform your home and is often a very cost effective way of getting the living space your family needs. Cornerstone can always be trusted to deliver a great result, with the minimum disruption and inconvenience possible.


Loft conversions are a brilliant way to maximise your home’s potential, they also throw up a unique set of challenges. With our skill and experience, Cornerstone can transform wasted space into the crowning glory of your home!


Whether modernising a neglected house or restoring a damp old cottage, Cornerstone can breathe new life into your home. We also offer a fully guaranteed damp-proofing and timber treatment service.
