If your home is starting to feel too small, an extension is usually the answer that makes the most sense. You keep the street you know, the schools, the neighbours and the garden, and you gain the space you are short of. We have been designing and building house extensions across Wigan and the North West since 1995, and we handle the whole job as one team: the drawings, the planning approvals, the build and the finish.
There is no chain of subcontractors to chase and no gaps between trades. The bricklayers, joiners, plumbers, electricians, plasterers and decorators all work for us, so your extension moves from foundations to final coat of paint without stalling. Every project comes with a Fair Trading contract, a full Peace of Mind Guarantee and a fixed written quote with no hidden costs.

A single storey extension is the most popular project we build in Wigan, and for good reason. Extending to the rear or side of your home can create the open plan kitchen and dining space most families are after, a bigger living room, a utility room or a downstairs bathroom. Done well, it changes how the whole ground floor works.
We design each extension around how you actually live. That might mean bifold doors onto the garden, roof lights to pull daylight into the middle of the house, or knocking through an existing wall to open the new space into the old. Many single storey extensions can be built under permitted development rights, which means no full planning application at all, and we will tell you at the first visit whether yours qualifies.
A double storey extension gives you roughly twice the space for much less than twice the cost, because the foundations, groundwork and roof are shared across both floors. It is the right choice when you need bedrooms as well as living space: a bigger kitchen below and a new bedroom with an en suite above is the combination we build most often.
Two storey extensions almost always need planning permission and careful structural design, and this is where having one team matters. Our own designers prepare the drawings, we submit and manage the application, and the same team then builds what was approved. We match brickwork, rooflines and window styles to your existing house so the finished extension looks like it has always been there. If you are weighing up a double storey extension against converting existing space, we can also talk you through a loft conversion at the same visit.
A wrap-around extension combines a rear and side extension in one L shaped build, wrapping the new space around the corner of your home. It is the most transformative option on this page: in one project you can gain a full width kitchen, dining and family space, plus a utility room or home office, without giving up your whole garden.
Wrap-arounds need more design thought than a straight rear extension. Steelwork usually carries the corner, drainage often needs rerouting, and the planning position is different because side and rear elements are combined. We deal with all of it in-house, from the structural calculations to the council paperwork, and we sequence the build so your kitchen stays usable for as long as possible.
The honest answer is that it depends on size, specification and what the new space is for, but you should not have to guess. These are realistic guide figures for extensions we build in Wigan and the surrounding North West, where prices are noticeably kinder than the national guides skewed by London rates.
As a rule of thumb, most of our extensions work out between £1,400 and £2,200 per square metre depending on the finish you choose.
Every job starts with a free visit and a fixed written quote, backed by our Fair Trading contract, so the figure you agree is the figure you pay. If you would rather spread the cost, finance options with monthly payments are available, and we can walk you through them with no obligation.
For most people, planning is the most off-putting part of an extension. For us it is a normal week. We have been taking extension drawings through Wigan Council and neighbouring authorities for three decades, and we handle the whole process for you as part of the job.
Many single storey rear extensions fall under permitted development, so no full application is needed. Larger rear extensions can often go through the prior approval route instead of a full application. Double storey and wrap-around extensions usually do need planning permission, and building regulations approval applies to every extension whatever its size. Our team prepares the drawings, submits the right application, deals with any questions from the council, and arranges building control inspections through to the completion certificate.
You get one point of contact from the first sketch to sign off, and we will tell you honestly at the first visit which route your project needs and how long it is likely to take.

COLLEEN, VERIFIED REVIEW
Not always. Many single storey rear extensions can be built under permitted development rights, and larger single storey extensions can often use the prior approval route. Double storey and wrap-around extensions usually need a full application. We check your property at the first visit, tell you which route applies, and handle whichever one it is.
A typical single storey extension takes around 8 to 12 weeks on site. Double storey and wrap-around extensions usually run 12 to 16 weeks depending on size and specification. If planning permission is needed, allow around 8 weeks for the council’s decision before the build starts. We agree a programme with you before work begins and keep you updated throughout.
Almost always, yes. Most of the structural work happens outside the existing house, and we keep the new build sealed off from your living space for as long as possible. We plan the knock-through for late in the programme and agree it with you in advance, and our teams tidy the site at the end of every day.
That is the aim on every job. We source bricks to match your existing walls, tie rooflines and tiles in properly, and match window and door styles so the extension reads as part of the original house rather than an add-on.
We do. Every extension needs building regulations approval covering the structure, insulation, electrics, drainage and fire safety. We arrange the inspections, work with building control throughout the build and hand you the completion certificate at the end. You will need that certificate if you ever sell the house, so it matters.
Yes. We offer finance options with monthly payment plans, so you do not need the full amount upfront. Ask when you request your quote and we will run through what is available with no obligation.
We build extensions across Wigan and the surrounding towns, including Standish, Leigh, Atherton, Ashton-in-Makerfield, Bolton, St Helens and Chorley, and across the wider North West.
Tell us what you are hoping to do with the space and we will come out, talk it through and give you a fixed written quote, free and without obligation. One team, one contract, one number to call from the first drawing to the finished room.
