Home Extensions
Need more space? We’ll build it properly — on time, on budget, and exactly how you pictured it.
What We Do
More Room. More Value. More Home.
A well-built extension is one of the best investments you can make in your home. It gives you the space you actually need — whether that’s a bigger kitchen, a playroom for the kids, a home office, or simply more room to breathe — without the hassle and cost of moving house.
At YBR, we handle the entire build from the ground up. That means the foundations, the structure, the walls, the roof, and the finishing — all under one roof (so to speak). You won’t need to juggle multiple contractors. We manage it all, and we keep you informed every step of the way.
Our Extension Services
What We Can Build For You
Single-Storey Extensions
A single-storey extension is the most popular way to add space to a home — and for good reason. Whether you’re extending into the back garden or out to the side, we can add a new room or open up your existing ground floor into something far more spacious and functional. Common uses include larger kitchen-diners, utility rooms, garden rooms, and home offices.
Double-Storey Extensions
If you need space on both floors — for example, a bigger kitchen below and an extra bedroom above — a double-storey extension is often more cost-effective than two separate projects. We handle the full structure, ensuring the build ties seamlessly into your existing home both inside and out.
Rear Extensions
Extending to the rear of your property is one of the most straightforward ways to gain significant extra space, and many rear extensions fall under permitted development — meaning no planning permission is needed. We’ll advise you on what’s possible for your property and handle the build from foundations to finish.
Side Extensions
Got unused space down the side of your house? A side extension can make surprisingly good use of it — adding a hallway, utility area, extra room, or even a full garage conversion into your home’s footprint. We assess the available space carefully and design the build to complement your property’s existing look.
Open-Plan Knockthroughs
Sometimes the space already exists — it’s just divided up in a way that doesn’t work for modern living. We knock through internal walls to create open-plan layouts, fitting the necessary steel beams and lintels to keep everything structurally sound. The result is a brighter, more connected living space that feels genuinely transformed.
Structural Work & Lintels
Any time a wall is removed or a new opening is created — whether for a door, a window, or an archway — the structure above needs proper support. We install steel beams and concrete lintels to carry the load safely, ensuring your home is as solid after the work as it was before. This is the kind of work that has to be done right, and we don’t cut corners.
Roofing
Every extension needs a roof, and a poorly built one will cause problems for years to come. We build and finish roofs to a high standard — flat roofs, pitched roofs, and lantern or skylight roofs — using quality materials that are built to last. We also carry out roof repairs and replacements on existing structures.
Frequently Asked Questions
Things People Often Ask Us
Do I need planning permission for an extension?
Not always. Many single-storey rear extensions fall under permitted development rights, which means you can build without applying for full planning permission — as long as the extension meets certain size and design rules. Double-storey extensions and side extensions are more likely to need permission. We’ll always advise you on where your project stands before any work begins.
How long does an extension take to build?
It depends on the size and complexity of the project. A straightforward single-storey extension typically takes between 8 and 14 weeks from breaking ground to completion. Larger or more complex builds — like double-storey extensions or projects involving significant structural work — will take longer. We’ll give you a realistic timescale before we start, and we’ll keep you updated if anything changes.
Will I need to move out while the work is being done?
In most cases, no. We work hard to minimise disruption to your daily life and will always discuss with you how to keep the most important parts of your home accessible while we build. There may be brief periods where certain areas are off limits, but we’ll plan around this with you in advance.
Do you handle everything, or will I need to hire other tradespeople?
We handle the full build — foundations, structure, walls, roof, and finishing. For specialist elements like electrics and plumbing within the new space, we work with trusted local tradespeople and can coordinate this on your behalf, so you’re not left trying to manage multiple contractors yourself.
How much does a home extension cost?
Every extension is different, so we don’t publish fixed prices — the cost depends on the size, type, materials, and complexity of the build. What we do offer is a free, no-obligation visit and a detailed written quote so you know exactly what you’re paying for before you commit to anything.
