House extensions in Hertfordshire
Yes, we can almost certainly help with your project, and we are genuinely local. We are a Hertfordshire builder based in Sawbridgeworth, and we design and build house extensions, loft conversions, bespoke kitchens and full home renovations for homeowners across East Hertfordshire and the surrounding area. If you are wondering whether the right builder for your extension or renovation is on your doorstep, they are.
Most people who contact us are not trying to move; they are trying to make the home they already have work better. In Hertfordshire's commuter towns and villages, where prices are high, the schools are good and families want to stay put, that usually means extending, converting the loft, reworking the kitchen, or renovating the whole house, rather than paying to move. That is exactly the work we do, and we handle it from the first design through the planning and building regulations to the finished, signed-off job, with one team and a clear point of contact throughout. To talk it through, book a free, no-obligation site visit on 07920 731533.

London's most useful extension
A quick, honest word on planning, because it shapes a lot of Hertfordshire projects, and we handle it for you as part of the job.
Two things come up often here. Much of Hertfordshire sits within the Metropolitan Green Belt, and while that sounds restrictive, you can usually still extend a home in the Green Belt, extensions are an explicit exception, provided the addition is not disproportionate to the original house. It is worth knowing where your property stands, and many town homes are not actually in the Green Belt even when surrounded by it. Second, the historic market towns and villages have conservation areas, and sometimes Article 4 directions, which reduce permitted development and mean design and materials are judged more closely, matching brick and detailing is often what secures approval. Along the Stort and Lea valleys, some properties also sit in flood-risk areas, which needs designing around rather than being a barrier.
None of this stops good projects; it just needs handling properly and early, which is what we do, checking your position, designing to what is achievable, and dealing with the planning and building regulations so you do not have to. Our guides on the Green Belt, conservation areas, Article 4 directions and flood risk explain each in plain English.

Matched to your house
Hertfordshire's housing is a real mix, and the type of home you have tends to point to the project that suits it.

Hertfordshire's housing is a real mix, and the type of home you have tends to point to the project that suits it.
Across all of them, the common thread is the same: a house in the right place, in an area people want to stay in, that can be made into the home they need. Whether that is more living space, another bedroom, a better kitchen or a whole-house renovation, it is the work we are set up for. The relevant guides, on extensions, loft conversions, kitchens and renovations, go into each in detail.

Why homeowners choose us
A few honest reasons homeowners here choose us:
We are genuinely local, based in Sawbridgeworth, so this is our home county, not a territory we reach into. We have been building for homeowners since 1995, and over 80 per cent of our work comes through recommendation, which is the accountability that matters most, it only continues if the last job was done well. We work as one team with a clear point of contact, so you always know who you are dealing with. We are honest about cost and time, quote clearly and itemise it, and handle the planning and building regulations as part of the job, seeing it through to the completion certificate. And we do the whole range, extensions, lofts, kitchens and renovations, so we can advise honestly on what your home actually needs rather than pushing one kind of job.
If you want to know what to expect from working with us, our guide on what to expect during your build, and the one on how to choose a builder, set it out plainly.
Where we build
We are based in Sawbridgeworth, in East Hertfordshire, and that is the heart of our patch. We regularly work across the towns and villages of East Herts and the surrounding area, including Bishop's Stortford, Hertford, Ware, Hoddesdon, Broxbourne, Buntingford and the villages between them, as well as just over the borders into west Essex and the London fringe. Being based here matters more than it sounds. It means we know the local housing stock, the way the different councils across the area tend to approach planning, and the ground conditions in the river valleys and on the clay, and it means we are close enough to run our jobs properly rather than stretching to reach them. If you are in East Hertfordshire, you are on our doorstep. For our home town, see our Sawbridgeworth page, and for one of the towns we work in most, our Bishop's Stortford page.

Cost, in the open
Every project is different, so the honest answer on cost is that it depends on the size, the specification, and the condition of your home, and the only figure that means anything is a real quote on your actual project. As a very rough guide, extensions tend to work out at a few thousand pounds per square metre depending on specification, but that is a starting point, not a price.
For an early sense of scale, our cost calculator gives you a ballpark before you speak to anyone. For a real figure, we will give you a clear, itemised quote after a free, no-obligation site visit, so you can see exactly what you are paying for, with no hidden extras.

We are based in Sawbridgeworth and work across East Hertfordshire and the surrounding area, including Bishop's Stortford, Hertford, Ware, Hoddesdon, Broxbourne, Buntingford and the villages between them, plus just over the borders into west Essex and the London fringe. If you are in or near East Herts, you are on our patch, and the best way to check is to call and ask.
House extensions (single and double storey, rear, side-return and wrap-around), loft conversions (rooflight, dormer, hip-to-gable and mansard), bespoke kitchens, and full home renovations and refurbishments, along with the structural work like knocking through and steel beams that goes with them. We design and build, and handle the planning and building regulations as part of the job.
Usually yes. Much of Hertfordshire is Green Belt, but extensions are an explicit exception, provided the addition is not disproportionate to the original house, so the scale is limited rather than ruled out. Many town homes are not actually in the Green Belt even when surrounded by it. We check where your property stands and design to what is achievable, and our Green Belt guide explains the rules.
They add some restrictions rather than stopping you. In the conservation areas of the market towns and villages, permitted development is reduced and design and materials are judged more closely, so matching brick and detailing matters. Well-designed schemes are approved regularly. We handle the planning and design it to suit the area; our conservation-area guide covers what to expect.
Some, particularly along the Stort and Lea valleys, where certain properties sit in flood-risk areas. It is something to design around rather than a barrier, and where a flood risk assessment is needed for the planning application, we make sure it is dealt with. Our flood-risk guide explains how it affects a project, and we check your property's position early.
Yes, as part of the job. We check whether your project needs planning permission or is permitted development, deal with any application, manage the building-control inspections, and see the work through to the completion certificate that protects it at resale. You are not left to navigate the systems yourself.
It depends on the size, specification and the condition of your home, so the only reliable figure is a quote on your actual project. As a rough guide extensions tend to be a few thousand pounds per square metre depending on specification. Our cost calculator gives an early estimate, and we provide a clear, itemised quote after a free, no-obligation site visit.
