Thinking about a home extension in London but dreading the whole process? We get it – moving house in London is expensive and stressful. That’s why at UK Property Group, we focus on creating beautiful extensions that give you the extra space you need right where you are. Over the past 15 years, our home extension builders in London have helped hundreds of families across the City of London, Brent, Camden, Harrow, and Hillingdon create spaces they actually love living in – spaces that work for real life and add genuine value too.
Here’s what we’ve learned after years of building extensions across London – there’s no one-size-fits-all approach. A rear kitchen extension in the City of London needs to function differently than a side return in Brent or a wraparound extension in Camden. Every home has its own character, and every family uses space differently. From the classic family homes in Harrow to modern apartments across Hillingdon, our architects, builders, and project managers work as one integrated team to deliver seamless results.
We begin with detailed surveys and feasibility studies to determine what’s possible and what actually makes sense for your space. Our bespoke architectural designs are created to complement your home’s existing style rather than compete with it. We take care of all the planning permissions and building regulations, so you don’t have to worry about the paperwork. Construction and finishing are carried out by skilled professionals who take pride in craftsmanship that stands the test of time. And from day one, your project is overseen by a dedicated manager who keeps everything running smoothly and on schedule.
What do you get? A London home extension that feels like it’s always been part of your house—one that functions beautifully for the way you live and adds genuine long-term value. No shortcuts. No nasty surprises.
We’ve become one of the leading home extension builders in London by doing exactly what we promise—on time, every time. Our clients consistently tell us what really matters: creating more space without the stress of moving house. That means no dealing with estate agents, no paying stamp duty, and definitely no packing boxes. Homeowners also value the increase in property value—up to 25% in many cases—which is especially important in London’s ever-competitive housing market.
Energy efficiency is another major priority. Our extensions are designed with proper insulation to help you stay warm without sending your heating bills through the roof. We also provide full planning permission support, drawing on our years of experience dealing with London boroughs—so we know which councils are cooperative and which require more care. All structural work and building regulation compliance is taken care of by our team, so you can rest assured everything is fully above board. From initial design to final construction, we manage every detail professionally—so you can go from concept to sipping your morning coffee in the new space without a hitch.
From the City of London and Camden to Brent, Harrow, and Hillingdon, we design home extensions that suit your property’s unique character and work for the way your family lives. Whether you’re looking for a budget-friendly solution or something high-end and bespoke, UK Property Group makes the entire process simple, transparent, and completely stress-free.
