PEOPLE ON THE TOOLS

Building quality structures that stand the test
From tilt-slab warehouses to seismic strengthening — priced properly, programmed honestly, and run by the same people who turn up on site.
Commercial construction
Offices, retail and light industrial, from the slab up. We hold the programme and the subcontractors, so you hold one contract.
Ask about thisCivil and infrastructure
Roading, drainage and subdivision earthworks with our own plant, which is why the digger turns up on the day we said it would.
Ask about thisDesign and build
One price and one date for the whole job. We carry the ground-condition risk instead of passing it back as a variation.
Ask about thisStructural and seismic work
Strengthening, portal frames and foundation remediation, engineered and signed off with the producer statements to match.
Ask about thisFitouts and refurbishment
Occupied-building work staged around your trading hours, with the noisy parts booked where they cost you least.
Ask about thisProject management
The same site manager from groundwork to handover, and a weekly written update whether there is news or not.
Ask about this
Engineering more than projects. We create trust that grows stronger over time
Stonecroft has been building in Hamilton since 1992. We started as a two-man residential outfit and now run four commercial crews, a civil team and our own plant, which means the excavator on your site answers to the same person as the carpenters. Most of our work is design-and-build: we price the whole job, carry the risk on the ground conditions, and give you one number and one date rather than a stack of subcontractor quotes to reconcile yourself. We are Site Safe certified, every job is covered by contract works insurance, and we have never walked off one.
Recent work
Te Rapa, Hamilton / 2026
Te Rapa distribution warehouse
A 4,200sqm tilt-slab warehouse and office, built on ground nobody wanted to price.
Cambridge / 2025
Cambridge medical centre
A working GP practice rebuilt around its own patients, one wing at a time.
Rototuna, Hamilton / 2025
Rototuna subdivision, stage three
Roading, drainage and services for sixty-four lots, on our own plant.
Built on satisfaction
Three tenderers priced our bad ground as a provisional sum. Stonecroft priced it as a fixed number and carried it. That is the whole reason we picked them, and it turned out to be the right call.
James Henderson
Te Rapa
They rebuilt our practice around our patients rather than the other way round. We saw people every working day of an eight-month build. Nobody else who tendered even offered that.
Sarah Whitman
Cambridge
They lost six weeks to the fish passage window instead of applying to work through it. Cost them money, cost us nothing, and it is the reason I would use them again.
Michael Chen
Rototuna
Steel columns installed overnight through the ceiling of a trading shop, made good before opening. One day lost across the whole job. I still do not entirely understand how.

Tendering
What a provisional sum in your tender actually means
It means the builder does not know, and you are carrying it. Sometimes that is fair. Often it is not.

Programme
Why we programme noisy work outside trading hours
It costs more and takes longer, and it is still cheaper than the tenant you lose.

Groundwork
Ground conditions are a decision, not a discovery
Two metres of soft fill is not a surprise if somebody digs a hole before the tender closes.
