What We Do

Every Client Is Different. So Is Every Contract.

Our flexible approach means your needs stay at the forefront of our thinking, whether it is a new headquarters, a ward that must stay open or a village hall built by people who live down the road.

We also provide planned and reactive maintenance, with over 40 years in industrial and commercial upkeep, and civil engineering, from retaining structures and underpinning to complex foundations.

Heritage and Conservation

From Near Ruin to Refurbishment of the Year.

Barcocks Barn in Drinkstone was a fragile, 200-year-old timber barn. Our craftsmen saved its frame and made it a family home with an oak and glass gable, and the National Federation of Builders named it Refurbishment of the Year.

“No fuss, no dramas, no arguments, just a hassle free project and a great result at the end.”

FAQs

Questions Clients Ask.

Anything else, call 01449 721233 and talk to the team.

What size of project do you take on?

From small works and planned maintenance to multi-million pound new builds. We have acted as principal contractor on a £3.75M new build, and our maintenance and small works team looks after alterations and repairs for long-standing clients.

Can you build while our site stays open?

Yes, and most of our clients need us to. We have built beside live food production, on operational hospital wards and in working schools, and upgraded a sports pavilion while play carried on alongside. Every phase is planned around the people who use the building.

Do you offer design and build?

Yes. Our commercial and industrial work includes design and build contracts, where early engagement lets us find value engineering opportunities and risks at design stage. We also build to architects’ designs under traditional contracts.

Do you work on listed and historic buildings?

Yes. Heritage work needs the right materials, techniques and traditional craftsmanship. We have restored the bell tower of a 15th-century parish church, near-derelict farm buildings and fragile timber-framed homes such as Barcocks Barn.

Which areas do you cover?

We are based in Needham Market and work across Suffolk, Norfolk and the wider East of England, with projects from Ipswich, Bury St Edmunds and the Suffolk coast to Norwich, Thetford and Cambridgeshire.

What accreditations do you hold?

Our Business Management System is certified to ISO 9001, ISO 14001 and ISO 45001. We are Constructionline registered, SafeContractor approved, members of the National Federation of Builders and registered with NHBC, so our new homes carry the Buildmark warranty.
