House Extensions
Adding an extension is one of the most effective ways to upgrade your living space and boost your property’s value – without the hassle of moving. At Coral, we manage your entire project across Yorkshire, delivering a seamless match with your existing home, improved layout functionality, and exceptional craftsmanship.
Energy Efficiency
Our extensions are designed with energy efficiency in mind, built using advanced insulation and modern glazing technology. Our roofs achieve U-values as low as 0.15 W/m²K paired with high-performance glass (1.0–1.2 W/m²K), to keep your heating bills down and your space comfortable year-round.
Weather Resistant
Our extensions are fully weatherproof and engineered specifically for your postcode, using high-performance components designed to withstand local winds and the UK’s varied weather conditions. Built for long-term strength, durability and reliability, they provide excellent protection against the elements while helping to keep your new extension warm, dry and comfortable throughout the year.
Expert Installation
Our skilled team of local Yorkshire professionals is committed to delivering exceptional workmanship on every project. With years of experience and meticulous attention to detail, we ensure every extension is finished to the highest standard. From the initial groundwork to the final installation, you can rely on us for quality craftsmanship, reliable service and outstanding customer care throughout the entire process.
Flexible Finance Options
We believe you should only pay for work once you can see and enjoy the final results. That’s why we operate on a strict zero-deposit and zero-stage-payment policy – no matter the scale or cost of your project. You won’t pay anything upfront or during construction. Your final balance is only due once your extension is completely finished to your full satisfaction.
House Extensions in Yorkshire
Every family uses their home differently. That’s why we design and build extensions tailored to your precise space and lifestyle needs – whether that’s an open-plan kitchen diner, a bright garden room, or an expanded lounge. We manage the entire process from initial design to final completion, ensuring your project is delivered on time, on budget, and to the highest standard.
Why Should You Choose a House Extension?
The high performing glass could help turn your extension into a living room or dining area, which could give you plenty of options to use your existing space.
The internal pelmet gives the illusion of a flat roof which can incorporate spotlights and speakers, perfect for social gatherings. When fitted with mneral wool, this could help improve thermal performance.
Our market leading house extensions could excel at preventing heat loss, which could be a great way for homeowners in Yorkshire to save on heating bills.
The central lighting panel could help add more natural light in your home, which could create the illusion of more space and increase its market value.
