Manchester and 25 miles around it · since 2009
Extensions, lofts and renovations for people who still have to live in the house while it happens. One fixed price, one site manager, and a photo every Friday.
“Finished a week early and the garden was left cleaner than they found it.”

What we build
Prices below are real starting figures from jobs we finished this year, not a marketing number with an asterisk.
Single and double storey, wrap-around and side return. We handle planning, party wall and building control so you only ever speak to us.

Dormer, hip-to-gable and Velux conversions with a proper staircase, an ensuite and enough head height to stand up straight.

Rewire, replumb, replaster and rethink the layout. Ideal for a house you have just bought and would rather fix once.
Typically 16–26 weeks on site
Fitted by our own joiners and tilers, with the messy weeks planned around school runs and a working kettle throughout.
Typically 4–7 weeks on site
Insulated, wired and warm in February. Built in six to eight weeks, usually without needing planning permission.

Your plot, your architect, our site team. A fixed price from foundations to the day you get the keys.

Before & after
Didsbury · side return and kitchen
Was
A dark back room, a cold utility lean-to and a wall between the kitchen and everyone in it.
Now
A 4.2m side return, one long room for cooking, eating and sitting, and a roof lantern over the table.
Rough price, right now
Likely range
£54,000–£66,000
A 24m² extension finished to a considered standard, including labour, materials, building control and VAT.
An estimate, not a quote. The fixed price comes after we have measured the house and drawn it.
How it goes
Most people have never run a building project and should not have to learn how. This is the whole thing, in order, with who does what.
Start at step oneWeek 0
We come to the house, listen to what is annoying you about it, and measure up. Free, and there is no follow-up call from a salesperson.
Weeks 1–3
Our architect draws two or three options with the cost written on each one, so you are choosing between real numbers.
Weeks 4–12
Planning, building control and party wall notices are lodged and chased by us. You sign; we queue.
Week 13
One page, one number, one date. If we get our sums wrong, that is ours to carry, not yours.
Weeks 14+
The same site manager the whole way through, dust sheets down every evening, and a photo update every Friday afternoon.
Handover
We walk the house with you, clear the list within fourteen days, and hand over certificates and a ten-year structural guarantee.

Our promise
Quoted from drawings, never from a phone call. The only things that move it are the things you change.
Ross or Priya from the first visit to the final snag. You get their mobile number, not a call centre.
Dust screens, floor protection and a swept site every evening. You still live here while we work.
Five stage payments against work completed. Nothing up front beyond the design fee.
We price the scaffold, the skips, the steel and the two wet weeks in March. Quotes that leave those out are not cheaper — they arrive later, in an envelope.

They started the week they said they would, which after three other quotes felt like a miracle. The Friday photos meant we never had to ask how it was going.

Side return extension · West Didsbury
We were living in two rooms with a toddler for four months. The team taped up a dust screen every single night and the house was never cold.

The price on the quote is the price we paid. One change was ours, it was costed in writing the same day, and that was the end of it.

Questions
Anything not here, ring and ask. We would rather talk you out of a bad idea early than build it.
In Greater Manchester most single storey extensions land between £2,200 and £2,900 per square metre including finishes. A 24m² kitchen extension is therefore usually £53,000 to £70,000. The estimator above uses the same rates we quote from.
Often not. Most rear extensions up to 4m on a detached house, 3m on a semi, and nearly all loft conversions under 40m³ fall under permitted development. We check your address on the first visit and tell you before you spend anything.
Yes, on about nine out of ten jobs. We seal the work area, keep one bathroom and a kitchen point live wherever possible, and plan water and power shutdowns with you a week ahead.
It changes only if you change something, or if something genuinely unknown appears once we open up a floor. Either way you get a written variation with the cost on it before anyone picks up a tool.
Anything within about 25 miles of the Manchester workshop: Trafford, Stockport, Salford, Bury and the Cheshire villages. Further afield we will still come and look if the project suits us.
Design work usually starts within two weeks. Build slots run roughly four to five months ahead, which is about the time planning and building control take anyway.

We measure up, tell you honestly whether the idea works, and say what it is likely to cost. If we are not the right builder for it, we will tell you that too.
