Learn about us

We're a family business​

Our aim is to provide you with a high quality build and finish that both you and ourselves are proud of, be it a small garage conversion to create an accessible bathroom, or a complete new build, or a total refurbishment of an existing property to create a beautiful home that you can enjoy for many years.

“I am very pleased with the property Jim and his team built for us. Very good craftsmanship throughout.”

A.G. Minster Lovell

New Builds

Build your new home with complete satisfaction


Complete your home improvement with quality craftsmanship

How are we different?


We have nearly 30 years’ experience in the construction industry, working throughout Oxfordshire and the Cotswolds. We have completed many varied projects, from building the new wing of a local nursing home, to the complete renovation of listed and period properties, to new builds and smaller projects such as garage and loft conversions, or even the addition of porches or conservatories.


We assist you with every stage of your project, from recommending an architect, if needed, and throughout the build itself. Our professional team covers a full range of trades such as groundworkers, bricklayers, plumbers, electricians, carpenters and bespoke Joiners , plasterers and decorators. No detail is overlooked.

High Quality

We pride ourselves on achieving a high quality of build and finish for our client and we believe we achieve this. The majority of our work, comes from word of mouth recommendations, where satisfied clients have passed our details on to family and friends.
