House extensions in Essex, built for how you live

Every extension is priced individually against your drawings and specification, and our projects start from £25,000. Size, glazing, groundworks and the standard of finish drive the cost far more than any average can capture, so you get one clear, transparent quotation before work begins. The site visit comes without obligation, and you have a clear figure within days.

Footprint, structural complexity, glazing and finish set the price of any extension. Finance and mortgage funded projects are welcome, arranged by you. Ask for a quote and you will have a clear figure within days of the site visit, not a guess. Our projects start from £25,000.

A kitchen extension combines two budgets: the build itself and the kitchen within it. Our projects start from £25,000, and the kitchen specification usually moves the total most, because that is where quality shows. We price both together, so there is one number and no gap between builder and kitchen fitter. Ask for a quote and we will price both.

A double storey extension usually costs less per square metre than a single storey, because the roof and foundations serve two floors. It is still a significant project, so treat any online average with caution. We give you a real figure after a site visit, transparently and without obligation. Most also need a full planning application, which we coordinate.

It can be, but no honest builder can say without seeing the house. Size, glazing, groundworks and finish decide what a budget buys, and the same goes for the £30k question. Our projects start from £25,000, so tell us your figure at the site visit and we will say plainly what it buys. Finance and mortgage funded projects are welcome.

National averages hide what matters: region, ground conditions, glazing and finish. In Essex and London, where we build, expect costs above any national headline figure. We quote against real drawings, and our projects start from £25,000, so you can qualify us in or out early. We respond to every enquiry within 24 hours.

Not always. Many single storey extensions fall under permitted development, while double storey schemes, corner plots and designated areas usually need a full application. We advise on the honest position at the first site visit and coordinate any application as part of our design and build process. Where permitted development rights have been removed, any extension needs an application.

Under permitted development, extensions and outbuildings together must not cover more than half the land around the original house, meaning the house as first built or as it stood on 1 July 1948. Go over half and you need planning permission. We check it at the site visit. Earlier extensions count towards the half, including any by previous owners.

Typically 3 to 6 months on site, after design and approvals. A straightforward single storey rear extension sits at the shorter end; double storey and wrap around schemes run longer. We programme honestly and keep you informed week by week. Craig answers how long will the build take? on film.

Usually, yes. Most extension work happens outside the existing rooms, and we run the site respectful of the fact you are living beside it. There is normally a messier period when the new space is opened through to the old, and we tell you when so you can plan. Craig covers can we stay in the home?

Almost every extension does, whatever the planning position: structure, insulation, drainage, glazing and electrics all have to be signed off. We coordinate building regulations compliance as part of the project, so the approvals are handled by the team doing the building, and you receive the completion paperwork at handover.

Extensions built on or near a shared boundary can bring party wall procedures into play before work starts. Whether yours does depends on the design and how close it sits to next door, so we flag it early and build any notice periods into the programme. Craig answers do I need to tell my neighbours?

Yes. Converting an attached garage turns dead storage into a real room without extending the footprint, and it often runs alongside a wider extension or layout scheme. Our minimum project value of £25,000 applies, so garage conversions usually make most sense as part of a bigger rethink of the ground floor; tell us what you have in mind and we will be straight with you.

Usually not, where the work is internal and the outside changes little, because it tends to fall under permitted development. Some newer estates had permitted development rights removed by a planning condition, so we check your property’s planning history first. Building regulations approval is normally needed either way, and we coordinate it.

Yes, and that is where it usually makes most sense with us. Converting the garage alongside an extension or a new ground floor layout lets the whole floor be planned once, priced once and built by one team, instead of treating the garage as an afterthought.
