Why Bespoke Means Planning Ahead
Bespoke architectural panels are not stocked on a shelf. Every project involves a design dialogue, tooling, material preparation, and quality-controlled production. This is what makes them bespoke — but it also means the procurement timeline is fundamentally different from off-the-shelf cladding. Architects who understand the production sequence can schedule engagement at the right moment, avoid costly programme delays, and give the manufacturer enough runway to deliver without compromise.
The total lead time from first enquiry to site delivery typically falls between 8 and 14 weeks, depending on project complexity, panel size, relief depth, and finish type. The timeline divides into four phases, each with its own critical-path dependencies.
| Phase | Duration | What Happens | Your Input |
|---|---|---|---|
| Design | 1 – 3 weeks | Pattern selection or bespoke design development. 3D modelling, relief depth studies, repeat layout drawings. Sample approval if required. | Design intent, elevation drawings, pattern preferences, material choice (PMAG or PUCOMP) |
| Tooling | 1 – 2 weeks | CNC master pattern milling, mould fabrication, quality verification against approved 3D model. | Final design sign-off. Changes after tooling add 1–2 weeks. |
| Production | 3 – 6 weeks | Casting, curing, finishing, quality inspection. Batch consistency checks across the full order. | Confirmed quantities, finish specification, RAL/NCS colour reference |
| Delivery | 1 – 2 weeks | Protective packaging, crating for international transport. Freight to site or nominated warehouse. | Delivery address, access constraints, site readiness confirmation |
When to Engage
The ideal moment to bring a bespoke panel manufacturer into the conversation is during RIBA Stage 3 (Spatial Coordination) or early Stage 4 (Technical Design). At this point the design intent is established, wall elevations are developing, and there is enough information to begin pattern development without premature commitment.
Engaging earlier — during concept design — is welcome and often productive. It allows the manufacturer to advise on what is feasible within budget and programme, flag any material constraints early, and contribute to the design language rather than simply execute a frozen specification. Engaging later — after tender — compresses the timeline and eliminates the opportunity for design iteration.
If your project involves multiple pattern designs across different areas (e.g. lobby, corridors, restaurant), engage early enough to stagger tooling. Each unique pattern requires its own mould — running them in parallel rather than sequence can save 2–4 weeks on the critical path.
Factors That Affect Lead Time
Relief depth. Shallow relief panels (5–15 mm depth) cast and cure faster. Deep sculptural panels (25–50 mm) require longer curing cycles and more careful demoulding, adding production time.
Panel size. Standard panels up to 1200 × 600 mm follow the typical timeline. Oversized panels (up to 3000 × 1500 mm for PMAG) require larger moulds, longer curing, and more careful handling — typically adding 1–2 weeks.
Finish complexity. A standard painted finish in a RAL colour adds minimal time. Cold-cast metal finishes (bronze, brass, copper patina) involve additional hand-finishing stages. Textured or multi-tone finishes extend the production window by approximately one week.
Quantity. Small orders (under 20 m²) move faster through production. Large-scale installations (200+ m²) require batch planning, staged quality checks, and phased delivery scheduling.
What We Deliver Before Production
Before a single panel is cast, every project receives a set of pre-production deliverables designed to eliminate ambiguity and give you full visibility of what will arrive on site. These include a 3D model of the approved pattern at production scale, a panel layout drawing showing the repeat arrangement on your elevation, a material and finish specification sheet, and — where requested — a physical sample in the specified material and finish.
Physical samples are typically 300 × 300 mm sections of the approved pattern, finished to production standard. They serve as the contractual reference for colour, texture, and surface quality. Sample turnaround is approximately one week from design approval.
Fitting Bespoke Panels into Your Programme
The most common programme risk with bespoke panels is late specification change. A pattern revision after tooling has begun means the existing mould is void and a new one must be fabricated — effectively resetting the production clock. The second most common risk is incomplete site information at the point of order: missing wall dimensions, unconfirmed fixing substrates, or undecided colour selections.
To protect your programme, freeze the design before tooling begins, confirm all quantities against measured site dimensions rather than drawing dimensions, and agree the colour reference (RAL, NCS, or physical sample match) at the point of order. These three decisions — pattern, quantity, colour — are the gates that release production.
