It goes wrong in a vague quote, an unpriced assumption, and a programme nobody wrote down. By the time the scaffold is up, the argument is already built into the job.
We work the other way round. The survey is thorough, the specification is written, and the price is fixed and itemised trade by trade — so when we start, the only question left is the finish you want.
What we build
Whether it is a single opening or a house taken back to brick, the survey, the specification and the fixed price work the same way.
Rear, side-return and wrap-around
The single biggest change most London houses can make. We handle it end to end: party-wall notices, building control, structural steels, glazing, and the decoration that makes the new space read as part of the old house rather than bolted onto it.
Typically 10–16 weeks on site
Dormer, hip-to-gable and mansard
A bedroom and bathroom without moving house. We work out early whether the head height and staircase will actually give you a legal room, and tell you if they will not — before you have paid for drawings.
Typically 8–12 weeks on site
Whole-house strip-out and rebuild
Taking a house back to brick and putting it back better. Rewiring, replumbing, new plaster, new joinery, restored cornice and floors — sequenced so trades are not undoing each other's work.
Typically 16–30 weeks on site
Supplied and installed, or fitted to your spec
The two rooms where the finish is judged closest. We will supply the units and stone, or install what you have specified with your own suppliers and designer — either way the substrate, the falls and the waterproofing are ours.
Typically 3–6 weeks per room
Steels, openings and matched brickwork
Knocking through, opening up a rear elevation, or repairing what has moved. Brickwork matched for colour, bond and mortar so a new opening does not announce itself from the garden.
Typically 2–8 weeks on site
Roofing, groundworks and the rest
The work a house needs whether or not you are renovating: roofs, chimneys, drainage, rendering, patios and the repairs found along the way. Priced as its own job, not smuggled into a bigger one.
Priced per job

How we work
We come and look properly — at the house, the drains, the roof line, and what the neighbours are attached to. You get an honest view of what is feasible, what it is likely to cost, and what we would not do in your position.
Drawings and a written specification, then a fixed price itemised trade by trade — groundworks, structure, first fix, plaster, joinery, decoration — so you can see exactly what you are buying and where the money is going.
One site manager who is your single point of contact, a written programme with dates you can hold us to, and a weekly report with photographs. Variations are priced and signed off before they are built, never after.
We walk the job with you, agree the snagging list and close it out. Electrical and gas certificates, building-control completion, appliance manuals and the guarantee, all handed over as one file.
Example timings for the demo — your own lead times would go here.
Where you stand
Our own work is guaranteed for a stated period from handover, in writing, with a named person to call. Manufacturers' warranties on materials and appliances sit on top of it.
Public liability and contract works cover for the duration, with electrical, gas and building-control certificates issued as part of handover rather than chased afterwards.
The final payment is held until the snagging list is agreed and completed. Nobody has to trust anybody — it is in the contract.
Example terms for the demo — your actual guarantee period, insurance cover and payment structure would be stated here.
Clients
We had three quotes and theirs was neither the cheapest nor the dearest — it was the only one that itemised the structural work instead of writing 'steels as required'. The final invoice matched it to the pound.
Six months with builders in the house and we never once had to chase them. The weekly report meant we always knew what was happening and what was coming, and the site was swept every evening.
They told us at the survey that our original plan would leave the stair non-compliant, and redesigned it before we spent anything on drawings. That conversation is why we used them.
Sample testimonials written for the demo — these are not real clients. Your own would replace them.
Request a consultation
Seven questions so our first reply is useful rather than “it depends”. The consultation is free, and nothing is committed until you have a written price in front of you.
Before you ask
Fixed price, itemised trade by trade, based on a written specification. Day rates only apply to small repair work where the scope genuinely cannot be defined in advance — and we will say so up front rather than discover it later.
It is priced as a variation and signed off by you before it is built, never billed afterwards. On older London houses we allow a contingency in the quote and tell you what it is for, so a surprise does not become an argument.
Yes. We submit building-control applications, arrange inspections, and serve party-wall notices. For planning we work with architects and planning consultants and manage the process on your behalf.
For a loft or a single extension, usually yes, and we will set up dust protection and a working sequence around that. For a full refurbishment it is rarely sensible — we will tell you honestly at the survey rather than halfway through.
A site manager who is your single point of contact, with our own trades for the structural work and long-standing subcontractors for specialist trades. You will not be passed between numbers.
Staged payments against completed work, set out in the contract before we start. We do not ask for large sums up front, and the final payment is not due until the snagging list is closed.
Yes — public liability and contract works cover, and we send the certificates with the quote as a matter of course rather than on request.
It varies with the size of the job. If you have a date you are working towards — a birth, a move, a school term — tell us at the consultation and we will say honestly whether we can hit it.
Call either number and you will get one of us, not an office. If we are on site we will call you back the same day.
