A Business with modern style and traditional values in West Sussex and the surrounding area

Until recently we were a family of professional construction managers. Having decided to go it alone this year we are embarking on a new venture to bring our experience to the benefit of smaller and more local home projects. We have experience over the last 50 years of subcontracting and small business owners through to major infrastructure and new home developments of varying sizes and budgets and we want to make this knowledge available to you.

With an understanding of class-leading build and knowledge to offer advice on modern methods of construction there is very little we have not seen.

Working with the client’s design team and other professionals including architects, Engineers, planning authorities and building control.

The key to our success is a passion to see and make change happen. As a consequence on the way, we have won our fair share of awards notably with NHBC for their converted ‘Pride in the Job’ along with Considerate Contractors and Environmental recognition which now extends to not only the local flora and fauna but also how we responsibly deal with waste.

We have brokered partnerships with local trades and suppliers to bring the best possible budgets and results to our works and have lived and breathed home renovations and extensions as long as I can remember (completing our own homes several times over), we can empathise with all that may be conscious of the intrusion into your life a home project such as this brings through your door and we try to endeavor to ensure the impact is minimal as if it were our own home.

Design and Procurement:

As a total solution provider, we can aid with all aspects of home design and construction projects including the procurement of labour and materials where needed or advise on the client’s own solutions.


We provide a safe and conscientious approach to complete your project with care and consideration along with program and budget.

We use experienced and qualified trade persons and understand that home improvement can be a difficult time and as such with giving it our personal touch.


We pride ourselves on delivering an exceptional service but in the unlikely event that you are not satisfied, we are there ready to help put things straight. Whether it be demonstrating new equipment or dealing with work elements that do not meet the expectation we want to assure you that we will be available beyond the project completion.Giving our clients reassurance is key to a good customer experience which we would hope will be passed on through referrals.

"Matt and Ron put together a new garage roof for me and I've rarely seen such attention to detail. They've done an excellent job and were also kind enough to perform some minor odd-jobs at the same time. Highly recommended and I plan to use them myself in the future."

Masonry garden building and dog grooming business salon fit out.

"Designed and built a combined masonry out building to house my dog grooming salon business. Including a total fit out with all services and some specifics for the care and well being of our doggie customers. Professional to the end and lots of advice given to produce the best result. Would definitely recommend and use them again in the future."

Sarah Eason
Single storey design and build.

"“They have re-furbished the last three houses we bought to the highest standards. I do make a lot of changes during the works but the team accommodated all of this and more without fuss. They were able to help with decision making where practicality precluded what I wanted, but I found this part of their service exceptional. Their interpretation of the design and drawings has always been very good. They were able to source and supply all the materials we wanted at a good cost and when we called them back to look at faulty items repaired or replaced quickly, all their aftercare has also been very good. On time and respectful to us while the works were underway and clearly an understanding of the impact they were having on our home during the works, you could not ask for more. We have had compliments on all the projects to date and would use them again without hesitation”"
