6 zones arranged for one-way material flow, with every item of equipment placed by tag.
One CAD/CAM file drives the router and boring machine, so no part is marked or drilled by hand.
Nesting puts 85–90 % of every sheet into parts, against 70–75 % on a manual saw.
In-house kiln drying to 10–12 % moisture stops doors and frames warping in Kenyan humidity.
Every machine is ducted to a central cyclone and the booth has a water curtain to capture overspray.
Offcuts and bagged dust become briquettes that fire the kiln boiler or sell as clean fuel.
Accurate CNC boring means cabinets ship flat and assemble on site with cam-locks and dowels.
The core routines operators follow, from start-up to batch release.

Mbao Precision Works Ltd is a CNC woodworking factory in Ruiru, Kiambu County. It makes kitchen cabinets, wardrobes, internal doors, office furniture and flat-pack ranges for homeowners, developers, contractors and retailers across the Nairobi metro. One CAD/CAM file runs through the whole factory, from design to nesting, CNC routing, edge banding and six-sided boring, so the company can offer factory-grade accuracy, repeatable quality and 10–15 day lead times, something most local carpenters cannot match.

Key assumptions: KES 130/US$. Capacity use of 40% in Year 1, 60% in Year 2 and 80% in Year 3. Material share falls as nesting yield improves and briquettes replace bought fuel. Payback is about 3 years on a cash basis (net profit plus depreciation).
Kenya's furniture demand is driven by urbanisation, the Affordable Housing Programme and a steady stream of new apartment blocks around Nairobi, Kiambu and Machakos. Every new home needs a kitchen, wardrobes and doors. Most of this work is still done by informal carpenters with hand tools, while mid- and upper-market buyers turn to imported flat-pack and ready-made furniture. A local CNC factory can match imported precision at shorter lead times, and it can make furniture to the exact dimensions of each room.
| Tier | Definition | Value (KES) |
|---|---|---|
| TAM | Kenya furniture, fitted kitchens, wardrobes and doors | ≈ 70 billion |
| SAM | Nairobi metro fitted furniture + panel-based furniture | ≈ 22 billion |
| SOM (Year 3) | Mbao Precision Works at ≈ 0.65% of SAM | 144 million |
| Competitor | Strength | Weakness |
|---|---|---|
| Established furniture brands | Showrooms, brand trust | Premium pricing, limited custom sizing |
| Imported flat-pack (China, Turkey, Malaysia) | Low unit price, modern designs | Fixed sizes, 8-12 week restock, weak after-sales |
| Informal carpenters (jua kali) | Lowest cost, flexible | Inconsistent quality, green timber, poor edges |
| Kitchen specialist importers | High-end finishes | Very high price, long lead times |
Differentiation: Made-to-measure at close to flat-pack prices, kiln-dried timber, 3D design previews before ordering, 10-15 day lead times, and a 5-year carcass warranty.
| Phase | Months | Key Activities |
|---|---|---|
| Setup & Approvals | M1-M2 | Company registration, factory lease, NEMA EIA project report, KFS registration, equipment orders placed |
| Fit-out | M2-M4 | 3-phase power upgrade, floor pads, dust ducting, booth and drying room, office and showroom |
| Equipment Arrival & Install | M4-M5 | Clearing at Mombasa, installation and commissioning, supplier technician on site |

| Commercial Launch | M6 | Showroom opening, developer contracts, first flat-pack retail listings |
| Scale-up | M7-M18 | Second shift on CNC and edging, contract cutting service, KEBS mark, UV finishing line evaluated |
| Risk | Impact | Mitigation |
|---|---|---|
| Board price and FX swings (imported MDF and hardware) | High | Two-supplier sourcing, 60-day stock buffer, price-adjustment clause in contracts |
| Timber supply and legality | Medium | KFS-permitted suppliers only, plantation cypress and pine, 1-month dried stock |
| Power outages damage CNC jobs | Medium | Standby generator for CNC, boring and extraction; UPS on controllers |
| Skills gap on CNC and CAD/CAM | Medium | Supplier training, TVET intern pipeline, documented programs |
| Dust fire or finishing fire | High | Spark trap, outdoor filter, daily housekeeping, booth interlocks, insurance |
| Slow developer payments | Medium | 30-40% deposits, staged billing, mix of retail and contract revenue |
