One-off buildings, difficult sites and briefs that cross categories. Feasibility first, priced before it is built, engineered for where it is going, and manufactured off site by the team that designed it.
Some briefs do not fit a category. A site nobody can get a concrete truck to, a building that has to be three things at once, a rollout that has to look identical in eleven countries, or a shape that only makes sense for one client.
Those are the projects this page is for. We take them from a first conversation through feasibility, design, engineering, manufacture and installation, with one team carrying the brief the whole way rather than handing it between consultants who have never met.
The thing worth knowing early is where a custom project's cost actually comes from. It is rarely the visible design. It is the parts underneath that get reinvented: structure, envelope build-up, service routes, connections and the jigs the factory needs.
So we keep those standard wherever the brief allows and spend the budget where it is seen and used. That single decision is usually the difference between a bespoke building that gets built and one that stays a drawing — and it is the first thing we will talk to you about.
Including the answer you may not want: that a standard category would serve this brief better, and which one.
Scope, specification and programme fixed at design freeze, so the number you approve is the number you are working to.
Every variation costed and agreed in writing before work proceeds, which is how a custom job stays out of dispute.
Proven structure, build-ups and connections beneath the custom design, so the budget goes where it is seen.
The people who priced it engineer it, build it and install it, so the brief does not get lost between companies.
Destination code, climate, wind and seismic loads, and the access route designed for from the first sketch.
Manufacture runs while foundations and services are prepared, which protects the programme on hard sites.
A one-off that works becomes a documented type, so the second and eleventh cost less than the first.
A sample rather than a limit. If it is a building and it can be made in a factory, it is worth an enquiry.
Seven stages with a decision at the end of each. You can stop after any of them, and nothing goes to the factory until the drawings are signed.
Brief, site, access, budget range and dates. We come back with whether it can be built, roughly what shape it takes, and whether a standard category would do it better and cheaper.
Two or three options with layouts, massing and an indicative cost range for each, so the trade-offs are visible while they are still cheap to change.
One option taken to a fixed specification, programme and price. This is the design freeze, and it is where the commitment is made on both sides.
Structural and services engineering, destination code compliance, permit drawings and your approvals. Nothing is released to manufacture until this is signed off.
Built in the factory with staged inspections you are welcome at, while foundations, services and access are prepared on site in parallel.
Transport planned around the real access route, then craning, assembly, connection and weathertightness by our own installation crews.
Systems commissioned and tested, snags closed, then as-builts, O&M manuals, certificates, training and warranty — with aftercare under an agreement if you want it.

On a custom project the specification is the output of the design stages, not an input. What follows is how each line gets decided, and it is confirmed on the approved drawings for your project.
All dimensions are nominal and confirmed on the approved drawings for your project.
One-off buildings, unusual sites and work in progress from delivered projects.










Send the brief, the site and the constraints — including the ones you think are dealbreakers. You will hear back shortly with next steps and an honest view of whether we are the right people for it.
If your project is closer to one of these than you thought, start there instead — the standard categories are quicker and cost less.
