Our History

Quantock Builders was founded by Robert "Bob" Dennehy, a craftsman passionate about restoring traditional and period properties. Operating close to home in Cothelstone, Bob made it a rule to take on projects within a five-mile radius, focusing on areas like West Bagborough and Kingston St Mary.

Throughout the 1990s, Quantock Builders earned a reputation for exceptional craftsmanship and meticulous organisation. This growth led the company to manage projects as principal contractors, ranging from small renovations to full-scale church restorations.

Bob achieved recognition as a Sovereign-approved damp proof surveyor, adding another layer of expertise to the company.

As the company celebrated its 10th anniversary, it underwent a rebranding, adopting a new logo and marketing approach. With a team of over 12 employees and numerous subcontractors, Quantock Builders began managing multiple projects simultaneously. Bob transitioned into the roles of surveyor and project manager, focusing on delivering quality and innovation. One highlight was the creation of a heritage joinery team to produce bespoke work for conservation projects, showcasing Bob’s ambition and dedication to excellence.

Quantock Builders became a private limited company, officially rebranding as Quantock Builders Limited. This year also marked the first steps into the business for future directors Simon Dennehy and Shaun Laverton, solidifying the family legacy.

The company celebrated its 20th anniversary with pride, continuing its passion for renovation and restoration. Projects included barns, churches, and manor houses, with standout achievements such as restoring a Grade I-listed priest house where Sir Francis Drake reportedly spent his wedding night.

The team also ventured into ecological building, completing two 3-bedroom Eco homes constructed with straw bales, lime, and clay.

After decades of dedication, Bob retired, leaving a lasting legacy. Simon ("Si") Dennehy took the reins, bringing fresh energy and ambition to the company.

Under Si’s leadership, the company expanded, tackling modern open-plan extensions and large-scale renovations while maintaining its expertise in historical and period properties.

Si established three dedicated teams, enabling the company to work on diverse projects across the South West. From barn conversions in Cullompton to extensions in Bishops Lydeard, Quantock Builders built a reputation that even reached the historic city of Bath, where the team took on extraordinary restoration projects.

Quantock Builders maintained a close relationship with the beautiful Cothelstone Estate, caring for over 18 listed properties, barns, and cottages with pride and affection. With a talented team of 10 employees, supported by skilled subcontractors and professional partners, the company fostered a vibrant and positive culture that grows stronger with every project.

The company embarked on a rebranding journey to reflect its innovative and modern approach while staying true to its roots in traditional and heritage works. Quantock Builders continues to thrive, blending craftsmanship, modernity, and legacy in every project.
