Key figures
The MiNeco system
Affordable isn't one trick. It's the combination.
MiNeco is coined from Minimum Eco-friendly. A building only becomes genuinely affordable and effective when three things are considered together: the design, the ground conditions, and the location. Get any one wrong and the building system alone can't save the budget.
On top of that, Mineco looks at a building as a whole — not just its walls — and works to lower the cost of every structural element: foundation, walling, structural grid, slab, roof and finishes.
Design, ground & location first
A technical site visit and soil assessment inform the foundation choice before a plan is finalised. Architectural and structural drawings, and a bill of quantities, are drawn up around what the specific site actually needs — using the latest CAD software.
Then, cost lowered at every element
Foundation, walling and slab each carry their own share of a build's cost. Mineco's precast system is engineered to cut each one individually — not just swap one expensive step for another.
| Element | Typical share of build cost | Mineco approach | Cost lowered by |
|---|---|---|---|
| Foundation | 20–30% | Suspended precast foundation | 30–40% |
| Walling | 15–20% | HICB interlocking blocks | ~30% |
| Slab | — | Precast waffle slab | 30–35% |
| Roof | — | Light steel roofing | ~20% |
| Structural grid | — | Beams & columns cast inside hollow blocks | No separate formwork or frame cost |
| Finishes | — | The Shell option | Client controls finish spend & timing |
Cost-lowered figures are against conventional strip-footing, quarry-stone-and-mortar, and timber-roof construction for the same element.
Budget option
"The Shell"
The simplest complete form of a Mineco House structure: roof cover, plastered wall surfaces, window and door frames, electrical conduiting, plumbing pipes, cement-sand screed, and steel front and rear doors — deliberately leaving finishes out so clients can choose their own within their budget.
How we build
No mortar. No plaster. No wasted days.
Hollow interlocking concrete blocks key into each other without mortar joints — cutting labour and construction time while staying strong, durable and eco-friendly. Beams and columns are cast directly inside the hollow cores, so no separate formwork is needed.
- No cement (mortar)
- No plaster
- Minimal formwork
- Minimal skilled labour
- Excellent thermal & acoustic insulation
- Community involvement in the build
- Aesthetic finish, eco-friendly
- 99% of materials reusable on demolition
- Robust and light — saves on structural grid
Foundations & slab
Suspended, not backfilled
A suspended slab foundation means no dumping, no backfilling, and no foundation walling — with the void underneath doubling as storage and insulation. Steel bars sit at 1-metre centres, and conduiting is laid before the pour.

Delivery principles
- Minimum time of construction45 days for bungalows, 90 for maisonettes — reducing overhead, labour cost and exposure to price fluctuation.
- Minimum cost of constructionLocally available materials and community labour, priced roughly Ksh 900,000–3,500,000 for a 2-bedroom bungalow through a 4-bedroom maisonette.
- Minimum labour requirementsSimple systems needing less skilled labour; in-situ community training within hours.
- Functional space allocationClients are guided to prioritise essential needs within local building by-laws.
- Eco-friendly materials and techniquesMinimal disruption to natural soil layering; trapped air in walls and slab insulates and buffers sound.
- Reduced timber useThe steel-frame roof system helps ease deforestation pressure.
- Bio-digester optionReplaces a septic tank, supplies cooking gas, and needs no desludging.
