Construction costs in Kenya: what to expect per square metre in Mombasa in 2026

The most common reason a design project stalls or collapses is not a planning refusal or a contractor dispute. It is a budget that was never realistic in the first place. A client who believes their building will cost KES 20 million when the market rate suggests KES 40 million will either redesign the project multiple times, over-borrow, or build something that does not match their original intent.

Getting the cost order of magnitude right at the outset — before drawings are commissioned, before a contractor is approached — is the most valuable thing the feasibility stage provides. The benchmarks in this article are derived from real project data for the Kenyan coastal market, updated for 2026. They are order-of-magnitude figures for feasibility decisions. They are not contract sums. A formal bill of quantities from a registered QS, prepared against completed drawings, is the correct basis for tendering and commitment.

Residential construction rates in Mombasa and the wider coastal region cover a wide range depending on specification, ground conditions, and building height. The table below gives the main reference points.

Simple low-rise apartment blocks and compact residential units with basic finishes — cement screed floors, bare plaster, standard sanitary fittings — typically come in at KES 37,000–40,000 per square metre. This is the entry-level rate for a building that is structurally sound and habitable but offers no premium specification.

Mid-market residential — the 2-3 bedroom house or apartment with ceramic tile floors, emulsion paint finishes, standard kitchen and bathroom fittings, and a basic air conditioning provision — benchmarks at KES 43,000–48,000 per square metre. This is the most common spec for private residential development in Mombasa's Nyali, Bamburi, and Kongowea corridors.

High-end residential with porcelain or stone floors, imported kitchen and bathroom fittings, VRF air conditioning, feature ceilings, and smart home provisions runs KES 58,000–65,000 per square metre. Exclusive and bespoke villas with full MEP packages, external landscaping to a high standard, borehole, and generator provision can reach KES 70,000–75,000 per square metre.

These rates are for the building itself — structure, envelope, finishes, and basic MEP. They do not include land, professional fees, statutory costs, external works beyond the building footprint, or VAT.

Commercial buildings carry higher rates than residential because of their structural requirements, MEP complexity, and finish expectations.

Low-rise office blocks up to four storeys, built to standard specification, benchmark at KES 50,000–55,000 per square metre. Neighbourhood retail — line shops, small shopping centres — runs similarly at KES 45,000–50,000 per square metre for basic open-plan retail space.

Business park campuses and CBD offices with raised access floors, full data and comms infrastructure, building management systems, and premium finishes benchmark at KES 58,000–65,000 per square metre. High-rise prestige CBD offices are at the upper end: KES 80,000–85,000 per square metre or above.

Shopping mall construction, which involves significant structural spans, complex MEP for HVAC and fire suppression, and high-finish common areas, benchmarks at KES 62,000–68,000 per square metre for the building shell and core fit-out.

Hospitality projects are among the most expensive to build on a per square metre basis in Kenya, because of their MEP intensity, fire requirements, finishes expectations, and typically complex geometries.

A budget hotel or guesthouse — simple bedrooms with en-suite, a dining area, and basic back-of-house — benchmarks at KES 75,000–80,000 per square metre. A three-star business hotel adds HVAC throughout, a more complex kitchen, a proper lobby, and meeting rooms, which takes the benchmark to KES 92,000–97,000 per square metre.

Five-star and resort properties — where MEP accounts for 30% or more of the construction cost, finishes are imported, and the building has multiple specialist areas — can reach KES 100,000–110,000 per square metre. These benchmarks reflect construction cost only; FF&E (furniture, fixtures and equipment) for a hotel is a substantial additional cost that varies widely by brand standard.

Industrial construction is at the lower end of the rate scale for simple godowns and warehouses — KES 37,000–40,000 per square metre for a straightforward steel portal frame structure with concrete floor, corrugated roof, and basic office provision. The rate rises with specification: loading dock features, temperature control, mezzanine floors, and hardened yards add cost.

High-tech factories and clean-room facilities, where the MEP is complex and the structural specification demands vibration isolation, controlled environment systems, and specialist flooring, benchmark at KES 65,000–72,000 per square metre.

The benchmarks above cover the building construction cost — structure, envelope, internal finishes, and basic MEP. They do not include:

Land cost. Plot prices in Mombasa range from KES 5 million to well over KES 100 million depending on location, size, and frontage. Land is always separate from construction cost.

Professional fees. Architect, QS, structural engineer, MEP engineer, and project manager fees are additional. For a mid-sized residential project, expect total professional fees of 12–18% of the construction cost. See the separate article on professional fees in Kenya for a full breakdown.

Statutory costs. County planning approval fees, NCA levy, NEMA fees, and fire clearance charges are project-specific but typically represent 1–3% of construction cost on a standard residential project.

External works. Perimeter walls, gate houses, driveways, external parking, landscaping, and connection to utilities are typically priced separately from the building.

VAT. Construction services in Kenya attract VAT at 16%. Whether VAT is included in a contractor's quoted rate depends on the contract structure. Always confirm.

Contingency. A 10% contingency allowance on construction cost is standard practice for a well-designed project. Poorly documented projects should carry 15–20%.

The right way to use these benchmarks is as a feasibility check, not a budget. Multiply your target floor area by the relevant rate to get an order-of-magnitude construction cost. Add professional fees at 15% and statutory costs at 2%. Check whether the result fits within your financing capacity before commissioning drawings.

If the construction cost alone exceeds your budget, the feasibility check has done its job: it has saved you the cost of a full design process for a project that was not viable. If the numbers work in outline, the next step is a formal feasibility study — a more detailed analysis with site-specific inputs, formal cost planning by a QS, and a full viability model.

The REDM estimate tool produces a preliminary cost range for your specific project — use type, target floor area, location, and specification level — in a few minutes, at no charge. It uses the same benchmarks described in this article, applied to your actual inputs.
