FAQ’s

  • Spring and early summer are ideal for starting most construction projects in Cornwall, as the weather is more predictable and daylight hours are longer. However, we work year-round and can plan projects to suit your schedule. Interior work like loft conversions or renovations can progress well through winter months. We'll advise on the best timing for your specific project during our initial consultation.

  • Start planning at least 6-12 months before you want work to begin. This allows time for design, obtaining planning permission (which can take 8-13 weeks), building regulations approval, and scheduling with builders. Early planning also helps secure better pricing and ensures your preferred start date. Contact us as soon as you're considering a project – we're happy to guide you through the process from the very beginning.

  • We recommend booking 3-6 months in advance, especially for larger projects or if you want to start during busy spring and summer months. For smaller jobs like garage conversions, lead times may be shorter. Getting in touch early means we can schedule your project properly and ensure we have the right team and materials ready. Contact us to discuss your timeline.

  • A typical new build takes 8-12 months from breaking ground to completion, though this varies based on size and complexity. Planning permission and building regulations approval add another 3-6 months before construction begins. Weather, ground conditions, and material availability can also affect timelines. We'll provide a realistic schedule during the planning phase and keep you updated throughout the build.

  • Renovation timescales vary significantly depending on the scope of work. A simple kitchen or bathroom renovation might take 4-6 weeks, while a full house renovation could take 3-6 months. Barn conversions and major structural work typically require 6-12 months. We'll assess your project and provide a clear timeline before work begins, factoring in any potential delays.

  • Yes, we offer landscaping services to complement your build. From driveways and patios to garden levelling and retaining walls, we can complete the external areas once the main construction is finished. Having one team handle both building and landscaping ensures better coordination and a cohesive finished result.

  • A good builder combines reliable communication, quality craftsmanship, and realistic timescales with local knowledge of Cornwall's building challenges – from coastal weather to ground conditions. Look for builders with a strong portfolio, positive testimonials, and transparent pricing. At Runnalls Construction, we pride ourselves on delivering all of this while treating every project with care and professionalism.

  • Absolutely. We provide landscaping for driveways, patios, garden walls, drainage, and general groundwork across North Cornwall. Whether it's part of a larger build or a standalone project, we can transform your outdoor spaces with the same attention to quality we bring to all our construction work.

  • For most projects, you'll need electricians, plumbers, and potentially heating engineers. Depending on your build, you might also need specialists for kitchens, bathrooms, plastering, or roofing. We work with trusted local tradespeople and can coordinate these services as part of your project, or you can arrange your own. We'll guide you through what's needed during the planning stage.

  • Most barn conversions in Cornwall require planning permission, though some agricultural buildings may qualify for permitted development rights if they meet specific criteria. You'll also need building regulations approval. We can advise on what permissions your project needs and recommend planning consultants if required. It's best to discuss this early in the planning process.

  • Loft conversion costs typically range from £25,000 to £50,000+ depending on the size, complexity, and finishes you choose. Factors affecting cost include whether structural work is needed, the type of staircase, dormer additions, and bathroom installations. We provide detailed quotes after assessing your property, so you'll know exactly what to expect before committing.

  • A garage conversion typically involves removing the garage door, adding insulation, installing windows, flooring, electrics, and heating. You may need building regulations approval but usually not planning permission. The work generally takes 4-6 weeks depending on the intended use. We handle everything from initial assessment to final finishes, creating a functional new room that matches your home.

  • Yes, we have experience working on period and listed buildings in Cornwall. Listed building work requires special consent in addition to planning permission, and we understand the sensitivity and regulations involved. We work carefully to preserve historic features while updating properties for modern living. Get in touch to discuss your listed building project.
