We don't just build basements. We build relationships

At Crownstone Group, we work with residential and commercial clients to survey, plan and construct basements as well as working in drainage and damp prevention and protection.

…but who are we really?  As a small and close-knit team with 20 years’ experience, we are passionate about producing structurally sound and elegantly finished projects.

…but that means nothing without you.

The most important part of our work is focused on our clients.

Whilst the buildings and projects we work on vary, the people we work with are always looking for the same outcomes from us:



You want a fair price and timescale that you can trust us to deliver on;


You want a contractor who will listen to your needs and work with you;



You want the end result to be of the highest possible quality, designed and built to last;



You want to know you’re not in it alone. Alone we can do so little, together we can do so much.


Crownstone are here

Above all else, we’re relationship builders. Without fairness, humanity and excellence, without trust and friendliness, the work we do is diminished.

Whatever the work we undertake, from the smallest of drainage designs to the largest new build developments, our focus is always on our clients first, and then the project

How do we know our work is complete?

When we have a smile and a happy client.
