Extensions & Renovations

At A1 Complete Builders, we specialise in crafting high-quality house extensions and renovations that enhance both the functionality and aesthetic appeal of your home. Based in Cornwall, our extensive portfolio includes a wide range of domestic projects, from elegant orangeries and timber-framed garden rooms to comprehensive two-storey expansions.

From your first enquiry to final completion, we provide a fully managed service tailored to your needs. We begin with an in-depth consultation to understand your goals, site conditions, and budget. Our experienced team can then support you through planning applications, building regulations, and structural considerations, offering clear advice at every step.

Design is a collaborative process. We work closely with clients and architects to develop practical, attractive solutions that suit your lifestyle and enhance your property’s value. Whether you need extra living space, a home office, or multigenerational accommodation, we’ll help turn your ideas into a workable, high-quality plan.
