We enjoy ambitious and challenging projects – the end results justify the extra effort and we work towards seeing our clients delighted with the finished product. We thrive on projects that call on all our skills, experience and imagination.

We will handle every aspect of the construction process for you and can also advise you on who might be the best architect and engineer for your project.

With 30 years’ experience exclusively in the construction industry, managing director Simon Dunning personally oversees all the projects. We also have highly skilled and motivated project and site managers, who will help arrange day-to-day activities, problem solve and stay accountable.

We are a considerate company that aims to build strong, lasting customer relationships – we listen carefully to what you want to achieve. We are happy to work as part of a team, taking a proactive role with our clients, the architect and engineers, building control and other interested parties.

We have a team of trusted subcontractors and specialist service companies who deal with mechanical-electrical installations, audio-visual installations and bespoke joinery to name but a few.  Towards completion we handover projects to an excellent team of decorators who deliver in the all-important completion stage.

With the operations manual completed the project is handed back to the client with the assurance that our assurance of high quality, defect-free workmanship remains in place.

Helping the environment - sustainable building practices and carbon offsetting

We are very conscious of the impact that building activity can have on the environment and that is why we do all we can to reduce onsite consumption of energy and to build responsibly, encouraging clients to take the more sustainable option wherever possible.

But no matter what, every building project has an impact on the environment.  To help offset the effects of this we now contribute to a certified carbon offsetting scheme, helping to plant 680 trees this year alone – read more about our carbon offsetting here.

Talk to us about how your project can also help offset carbon.
