Why Hayes homeowners choose modular
Hayes is changing fast. With Heathrow on the doorstep, the Elizabeth line running through the heart of the town and new development reshaping the old EMI quarter, more families than ever are choosing to put down roots here — and then quickly finding they need more room. If you love your street but you've outgrown your floor plan, extending often makes far more sense than moving.
That's where EazyBase comes in. We design and build modular home extensions in Hayes that are manufactured in our Blackburn factory in as little as four weeks, then installed at your home in under a week. Because the building work happens off-site, you avoid months of scaffolding, skips and disruption — and you get a precision-built space with a quality of finish that's hard to match on a traditional site.
Whether it's a bigger kitchen-diner, a proper home office, a playroom or a garden room, we handle the design, the build and the installation from start to finish.

Built for Hayes homes
Extending an interwar terrace or semi in Hayes
Much of the housing in Hayes Town, Botwell and Yeading dates from the interwar years — solid terraces and semis built when the town grew up around its factories. These homes were built well, but their kitchens and rear rooms are often small by modern standards. A single-storey rear extension is usually the most natural way to open them up, creating the kitchen-diner or family room the original layout never had. Our designers work with the proportions and brickwork of period homes so the new space feels like it belongs, not like a bolt-on.
Planning in the London Borough of Hillingdon
Hayes falls under Hillingdon Council, and the good news is that permitted development rights often cover single-storey rear extensions on houses — meaning many projects can go ahead without a full planning application. That said, the rules depend on your property type, its history and any previous alterations, so it's always worth checking with Hillingdon Council before work begins. We prepare drawings suitable for planning or lawful development applications and guide you through the process, so you know exactly where you stand before anything is built.
Space that works as hard as the Elizabeth line
Hayes & Harlington station's place on the Elizabeth line has changed how people see the town — fast links into central London and out to Heathrow have made Hayes a genuine long-term base rather than a stepping stone. For homeowners, that's a strong argument for investing in your current house instead of paying stamp duty and moving fees to leave it. Well-designed extra living space tends to make a home more usable and more appealing, and it lets you stay connected to everything that drew you to Hayes in the first place.
Why factory-built works so well in Hayes
Traditional extensions on busy terraced streets mean months of deliveries, mixers and mess. Our approach is different: your extension is built in our Blackburn factory in as little as four weeks, in controlled conditions and to millimetre precision, then delivered and installed at your Hayes home in under a week. For families extending a starter home — often while juggling school runs and Heathrow shift patterns — that shorter, tidier on-site phase is a genuine relief. Less time with your garden as a building site, and a finished space you can start living in almost immediately.
