Custom Product Design

You have a brief — a form, a function, a feeling. We take it from concept through to a finished, production-ready object. Our process covers 3D modelling, prototype testing, mould-making and casting in your chosen material.

We work with clients who need objects that don't exist yet — for interiors, hospitality, retail and brand environments.

How we work

From idea to finished object

01
Brief
We start with a conversation. Tell us what you need — the object, the feel, the function, the deadline. We'll scope the project and give you a clear proposal.
02
3D Design
We model your object in 3D — refining form, proportions and detail until it's exactly right. You review and approve before anything physical is made.
03
3D Print and Mould
We print the master form in-house, then create a production mould. Precision here means consistency across every cast piece.
04
Casting
Each piece is hand-cast in your chosen material — Jesmonite, resin, cement or a composite blend. Every cast is individually inspected before finishing.
05
Finish and Deliver
Hand-finished, quality checked and carefully packaged. We deliver across South Africa and can arrange international shipping for larger orders.

Most custom projects take 4-8 weeks from approved brief to delivery. We'll give you a detailed timeline before any work begins.

What we work with

Our materials

Jesmonite
AC100 · Water-based
A gypsum and water-based acrylic resin system that produces a stone-like finish with excellent detail. Lightweight, low VOC and versatile — pigmentable, texturable and suitable for indoor or outdoor use.
Low VOCPigmentableStone finishIndoor / outdoor
Resin
Polyester · Epoxy
High-detail casting resins that capture fine surface texture and sharp edges.
High detailDurableClear or pigmentedMatte or gloss
Cement
GFRC · Standard mix
Raw, industrial and considered. Cement-cast objects carry a natural weight and texture that no other material replicates. We work with standard and glass-fibre reinforced mixes.

Composites
Custom blends
Proprietary blends combining aggregate, pigment and binder to achieve specific aesthetic outcomes. Terrazzo-effect, stone-effect and custom texture profiles — developed to meet your brief.
