The honest answer is: it depends — on the size of the house, the finishes you choose, the site, and how well the project is managed. But "it depends" is not useful when you're sitting with your family trying to plan. So let's break down where the money actually goes.
The five big cost drivers
- Land and site preparation. The plot itself, levelling, filling, retaining walls where needed, and getting materials to site. A flat, accessible plot in a serviced area can save you hundreds of thousands compared to a steep or remote one.
- Structure. The foundation, walls, roof and openings — typically the largest single block of the budget. This is also where cutting corners is most dangerous.
- Finishes. Tiling, doors, windows, kitchen, bathrooms, paint, electricals and plumbing fittings. Finishes are where two houses of identical size can differ by a factor of two in total cost.
- Professional fees and approvals. Design, drawings, county approvals and, where the project size requires it, engineer sign-off. Budget for these from day one; they are not optional extras.
- Contingency. Things you cannot see today — rock on site, a price jump in steel, rain delays. A contingency of 10–15% is not pessimism; it is planning.
A practical way to think about it
Most builders in Kenya work off a rough cost per square metre, and for a modest, well-built family home the range is wide — easily double from the simplest specification to a high-end one. That range is exactly why a detailed, itemised quotation matters more than a headline figure. When we quote, every material, labour line and finish is listed so you can see what you are paying for — and what to adjust if the total needs to come down.
How to keep a build budget honest
- Design to your budget, not the other way round. Decide the envelope first, then shape the house to fit it. Rooms that are oversized "just in case" are the most common source of overrun.
- Fix your finishes before you break ground. Changing tiles and windows mid-build is where money quietly disappears.
- Buy big-ticket items early and store them. Prices move; a locked-in price is a saving.
- Agree a payment schedule tied to milestones. You should never pay far ahead of work completed.
- Ask for weekly progress updates with photos. You cannot manage what you cannot see.
The one question to ask any builder
"What is not included in this quotation?" The answer tells you most of what you need to know about how the project will actually run.
Every project is different, and indicative figures age quickly. The reliable route is a site visit and a proper, itemised quotation. If you would like one — with no obligation — request a quote and we will walk your project with you.
