Character Builders South West Ltd is a local, family-run business based on the picturesque edge of Dartmoor National Park. Established in 1997, the company is led by four brothers who each have areas of specialism, ensuring expertise across the entire range of building work. Our philosophy is to work in harmony with the natural aesthetic of the surrounding countryside, creating buildings that are not only functional but also visually appealing and in keeping with their environment.
Our Services
At Character Builders, we specialise in period property maintenance, with a diverse portfolio that includes work on Devon Long Houses, barn conversions, barn restorations, cottages, churches, timber frames, and general maintenance. We take a progressive and forward-thinking approach to restoration work, combining modern and traditional techniques to ensure the highest standards of craftsmanship. Our focus is on working with sustainable materials, and while we cover most aspects of general building work, including working with oak, cob, and lime, we also forge close links with specialist craftsmen who work alongside us when needed.
Our team of dedicated professionals is committed to delivering quality building, joinery, and decoration services. We take pride in our attention to detail, ensuring that every aspect of our work is completed to the highest possible standard. Our mantra is 'every detail counts', and we strive to uphold this philosophy in every project we undertake.
