Why most builds go wrong before anyone lifts a shovel
In twenty years of rear extensions we have never seen a job overrun because someone laid bricks slowly. It overruns because a steel was ordered late, because the structural calculations came back needing a bigger pad foundation, or because nobody asked where the boiler flue was going until week six.
That is the whole of our method. We do the boring, unglamorous sequencing work up front, in writing, and we charge for it as a separate pre-construction stage so you are not paying for guesses.
What a fixed price from us actually includes
- Building control fees, structural engineer’s calculations and the party wall surveyor’s time.
- Every steel, pad and lintel priced off the engineer’s drawing, not off a rule of thumb.
- Skip hire, scaffolding, protection to your existing floors, and a weekly clean.
- A named site manager who is on your job and no more than one other.
If it is not on the schedule of works, it is not in the price — and we would rather argue about that in week zero than week twelve.
What it does not include, honestly
Kitchens, bathroom sanitaryware, flooring and decoration are carried as provisional sums against a budget you set. You buy what you like; we fit it. If you underspend, you get the difference back on the final account.
