Ask about thisOne workshop,
two markets
Design and manufacturing under one roof: architecture and product design at one end, printers, scanners and drones at the other, and the training to run any of it.

What the workshop is for
01Mission
Make good fabrication ordinary
The machine, the material and the person who runs them, from one place, on one timeline.
02Vision
A workshop in every market we serve
Local stock, local prices and local support: a market, not a shipping address.
03How we work
Short loops, and say the hard thing early
Weekly reviews, and a no on day one rather than a delay on day thirty.
How it got here
From a garage to two markets
- 2019
The first printer
One machine in a garage in Clarksburg, printing architectural models for local practices.
- 2021
The workshop
Six printers, a CNC router and a 60 W laser, and the first clients who wanted production runs rather than models.
- 2023
Capture and survey
Scanning and drone work added, because clients kept asking for a model of a building that already existed.
- 2025
Kenya
The Nairobi market opened as a market rather than a shipping destination: local stock, local pricing, local delivery tiers.
- Now
Umbaji Africa
Its own name and mark, serving Kenya from the Nairobi workshop.
The people
Who you actually deal with
Roles rather than titles: on a job this size you want to know who does the thing.
Nairobi
Amara Otieno
Runs the Nairobi workshop
Commissions every machine that leaves the shop, and trains whoever is going to operate it.
