What we
do, in three
short lines.
We build extensions. We convert lofts. We turn tired terraces into houses people don't want to move out of. We pour the concrete and lay the bricks ourselves.
We work in Northampton. Not the other half of the country, not from a national franchise. From Abington Street, with our names on the vans, in postcodes you can drive across in fifteen minutes — NN1 through NN8.
And when we hand you a finished job, the company name on the invoice is the same one Companies House lists. Plain English quotes. Fixed dates. Photos every week the work is live.

What it tends to cost.
Two clicks for a ballpark. Not a quote — we don't bill for work we haven't seen. But you should know what range to expect before you ring.
Indicative range for a typical house extension in Northampton. Final price depends on access, finishes, and what the structural survey says.
A finished extension is the cheapest move a family ever makes. We make sure it doesn't feel that way.
Companies House registered (no. 16288736). Public, accountable, on the record.
One crew, one site at a time. No subbing out to whoever has the diary.
From site visit to written quote. Plain English, fixed-line items, no upsells.
Northampton and the neighbouring postcodes — out beyond on request.

How a job actually goes.
Most builderspretend the process is four neat steps with stock photos of clipboards. It isn't. This is, more or less, what happens between the first phone call and signing off the job.
