Every successful building project starts with a clear plan and a team you can trust to deliver it properly. As experienced builders in Dorchester, KAP Woodwork & Building Services follows a structured, transparent approach that keeps you informed and in control from start to finish.
Whether you're planning an extension, bespoke carpentry, or landscaping, our Dorset building services are designed to deliver quality without stress.
We begin with an initial consultation, taking the time to understand your ideas, budget, and how you want to use your space. This allows us to provide practical guidance based on real experience working across homes in Dorchester, Weymouth, and surrounding areas. As trusted builders Dorchester Dorset homeowners rely on, we focus on solutions that are both functional and long-lasting.
Why Choose Our Construction Company in Dorchester?
Choosing a builder is a big decision. Here's why Dorset homeowners trust us with their most important projects.
Years Combined Experience
Our builders in Dorchester bring decades of hands-on experience in construction, carpentry, and landscaping. We've worked on everything from modest bathroom refits in Broadmayne to large-scale extensions in Dorchester — and we bring that depth of knowledge to every project.
Family-Run Business
We're a close-knit, family-run team — not a faceless national company. That means you get personal accountability, honest advice, and a genuine commitment to getting things right. Your home matters to us as much as it does to you.
Dorset-Based Local Team
Based in Broadmayne, we know the local area inside out — from Dorset's conservation planning rules to the best local suppliers. Being local means faster response times, no call-out charges, and a team that's invested in the community.
Quality Craftsmanship Guaranteed
We never cut corners. Every joint, every finish, every detail is held to the highest standard. Our work speaks for itself — and our growing list of five-star reviews from homeowners across Weymouth, Bridport, and Sherborne proves it.

Homes across Dorset vary in style, from traditional cottages to modern family properties, and each requires a tailored approach. At KAP Woodwork & Building Services, we deliver bespoke solutions backed by professional Dorset building services, ensuring every project complements your home and lifestyle. Our house extensions are designed to maximise space, improve layout, and bring in natural light - ideal for growing families or those looking to enhance their living environment.

Frequently Asked Questions
Answers to the questions we hear most often from Dorset homeowners.
How much does a house extension cost in Dorset?+
House extension costs in Dorset typically range from £30,000 for a modest single-storey rear extension to £80,000+ for a large double-storey extension. The final price depends on size, specification, ground conditions, and finishing choices. We provide detailed, transparent quotes after a free site visit so you know exactly what to expect — no hidden costs.
Do I need planning permission for a garden room?+
Most garden rooms fall under Permitted Development rights, meaning you won't need a full planning application — provided the structure meets certain size, height, and placement criteria. For example, it must not cover more than 50% of your garden and generally can't exceed 2.5m in height if within 2m of a boundary. We'll advise you on exactly what's required for your property during our free consultation.
How long does a typical extension take to build?+
A typical single-storey extension takes around 8–12 weeks from breaking ground to completion. Larger double-storey extensions usually take 12–16 weeks. Timescales can vary depending on weather, structural complexity, and any bespoke finishes. We provide a clear project timeline before work begins and keep you updated throughout.
Do you offer free quotes?+
Yes — we offer completely free, no-obligation quotes for all our services. We'll visit your property, discuss your ideas, take measurements, and provide a detailed written quotation. Call us on 07426 953891 or use our contact form to arrange a convenient time.

We are based in Broadmayne and cover the whole of Dorset including Dorchester, Weymouth, Bridport, Sherborne, Blandford Forum, Wareham, Portland, and all surrounding villages. We also take on projects in neighbouring counties by arrangement. No job is too close to home or too far across the county.
