Home Extensions in Cardiff and South Wales

Create the Space Your Family Deserves

When your current home no longer meets your family's needs, a well-designed extension offers the perfect solution. At GENTCO, we've been helping homeowners across South Wales create additional living space for over 30 years, designing and building extensions that seamlessly integrate with existing properties whilst adding significant value and functionality.

Types of Extensions We Build

Every home and family is different, which is why we offer a comprehensive range of extension types to suit various needs and budgets. Single-storey extensions are ideal for expanding ground-floor living areas, creating open-plan kitchen-diners, or adding a home office or playroom. Double-storey extensions maximise your building footprint by adding space on multiple levels, perfect for growing families needing extra bedrooms and living areas.

Rear extensions remain the most popular choice, transforming the back of your property into light-filled living spaces that connect beautifully with your garden. Side return extensions make excellent use of often-wasted space beside your property, whilst wrap-around extensions combine side and rear extensions for dramatic transformations.

Our Extension Process

Based in Cardiff and serving homeowners throughout South Wales, we manage every aspect of your extension project from initial concept to final completion. The process begins with understanding your vision, budget, and how you want to use the new space. We then develop detailed plans, handle all planning applications and building control requirements, and keep you informed throughout.

Our experienced team coordinates all trades and materials, ensuring your project runs smoothly and efficiently. We understand that building work can be disruptive, so we work hard to minimise inconvenience, maintain clear communication, and keep your home as functional as possible during construction.

Quality and Attention to Detail

With over three decades of experience, we've built a reputation for exceptional craftsmanship and attention to detail. We ensure your extension matches your existing property's character whilst incorporating modern standards of insulation, energy efficiency, and building regulations compliance. From foundations to roofing, every element is constructed to the highest standards.

We take pride in the finishing touches—matching brickwork perfectly, ensuring seamless internal transitions between old and new spaces, and creating beautiful rooms that feel like they've always been part of your home.
