What we build
What we build
Family houses, cottages for short stay letting, rental units, farmhouses on plots with no mains water or power, and extensions to houses that are already standing.
Bungalows
A bungalow is everything on one level. It is the most common house built in Kenya and usually the cheapest way to get a given number of bedrooms, because there is no staircase, no suspended slab and no second scaffold.
A 3 bedroom bungalow around Nanyuki normally lands between KES 5.5M and KES 10M all in.
Maisonettes
A maisonette is a house on two or three floors with its own entrance. It is what people build when the plot is small, when the view is worth reaching for, or when they simply want the bedrooms separate from the living space.
A 4 bedroom maisonette normally lands between KES 9M and KES 18M all in.
Holiday homes and Airbnb units
TimberStone designs and builds holiday homes and holiday cottages in Nanyuki and the Mount Kenya region. Plan a private weekend home, a self-catering cottage or an Airbnb development around your plot, budget and intended use, with architectural and structural drawings, construction and workshop-made joinery.
Budget by floor area, ground conditions and specification; include services, external works and furnishing separately.

How we work
How a job runs
Seven stages, from the first visit to your plot through to handover. We do the drawings, the structural design and the building ourselves, so there is one contract and one team on site.
- 01
Concept and feasibility
A visit to the plot, a look at the ground, and a rough cost. This happens before you pay for any drawings.
1 to 2 weeks
- 02
Architectural design and drawings
Floor plans, elevations, sections and the drawings the county wants to see. We draw them in our own office.
3 to 5 weeks
- 03
Structural designs and drawings / civil engineering
Foundations, slabs, columns and roof structures, sized from trial pits dug on your plot.
2 to 3 weeks
- 04
County approvals and permits
We prepare and submit the drawings, then follow the approval through the county on your behalf.
4 to 8 weeks, depending on the county
- 05
Construction and concrete works
Stone and concrete construction by our own team. Foundation, walling, slabs, roofing and plaster.
Programmed per project

Snagging and handover

What makes us different
Custom timber furniture, doors and interiors in Nanyuki
Most contractors here buy joinery in. We have a kiln and a workshop, so the doors, ceilings, floors and wardrobes in your house are cut and fitted by our own people.
Drying timber takes about three weeks and it costs money, so it is the step most often skipped. Undried timber shrinks once it is inside a warm finished house. Doors stop closing, floors gap and wardrobe doors go crooked. We build the house and we make what goes into it, so that problem comes back to us.
Budget
What does it actually cost?
We publish indicative construction costs and material price ranges, with their review date. Use them to plan a starting budget, then ask us for an itemised quotation.
Work out your own figure
Set the size, the finish and the county. Tick the water, the waste, the approvals and the boundary wall, and you get the whole budget rather than the pretty part of it. Nothing you type is sent anywhere.
What materials cost, county by county
55 items covering cement, steel, stone, sand, mabati, timber, labour and professional fees, adjusted for how far the lorry has to come. Reviewed August 2026 and free for anyone to use.
Tell us about your plot
Send the location, the plot size and roughly what you want to build. We will give you a budget range and tell you what to do next.
