The Truth About Project and Design Pricing in Kenya: A Transparent Cost Guide
For anyone planning to build a custom home or a luxury maisonette in Kenya, the moment of truth always comes down to the budget. You can have the perfect design—a double volume sunken lounge, all-ensuite bedrooms, and a fully-equipped rooftop—but if you don’t anchor your budget in reality, the project will stall.
At Centimax, we believe in radical transparency. Construction costs in Kenya are volatile, but when you work with experienced professionals, you gain clarity and control. We demystify the numbers, moving beyond vague estimates to show you exactly how project and design pricing works, using the universally accepted metric: Cost Per Square Meter.(KES/m^2)
Understanding the Foundation: Construction Cost Per Square Meter

The most reliable way to budget for your home is by calculating the total area of your planned house and multiplying it by the prevailing rate per square meter.
Current Benchmarks for Nairobi Region (2024/2025 Estimates):
| Project Type | Finish Level | Average Cost (KES per m2) | Estimated Cost Per Sq. Ft. (KES) |
| Middle-Class Maisonette | Standard Finishes | 53,800 – 61,000 | 5,000 – 5,670 |
| Luxurious Maisonette | High-End Finishes | 84,000 – 94,270 | 7,800 – 8,760 |
| Standard Bungalow | Standard Finishes | 48,750 – 54,730 | 4,530 – 5,085 |
Note: These figures are based on industry surveys and cover the cost of construction materials, labour, and management overhead, excluding land and professional fees.
Example: Budgeting for a 4-Bedroom Luxury Maisonette
Let’s assume your Centimax 4-bedroom luxury maisonette has a total floor area of 250m^2
Using the lower-end figure for a luxury finish (KES 84,000/m^2):
This gives you a clear, realistic cost base.
The Non-Negotiable: Professional Fees (Architects & Quantity Surveyors)
Many clients attempt to cut costs by seeking unlicensed or “cheap” designers. This is the single biggest mistake you can make, as it guarantees expensive rework later. The fees for professional services are governed by the Architects and Quantity Surveyors Act (Cap 525) and cover the crucial stages of the project.
The Role of the Architect
An architect does much more than “draw a plan.” They:
-
Develop the concept, ensuring your sunken lounge and rooftop amenities are functional.
-
Produce detailed working drawings for the contractor.
-
Manage the required county and statutory approvals (NEMA, NCA).
-
Supervise the work on-site to ensure quality.
The mandatory minimum fee for an architect executing a complete scope of services on a new project is 6% of the total construction cost (excluding VAT).
The Role of the Quantity Surveyor (QS)
The QS is your financial watchdog. They:
-
Prepare the Bill of Quantities (BQs), which is the detailed shopping list that controls contractor pricing.
-
Manage the tender process and contractor selection.
-
Track the project spend and issue valuations for payment.
The QS fee is similarly based on a percentage of the construction cost, usually starting at 3.5% to 4.5%.
Beyond Construction: The Hidden Costs That Stall Projects
Successful budgeting accounts for the necessary costs outside of the physical building:
-
Permits and Approvals (2-5%): Fees vary by county, but they include County Plan Approval Fees (often approx 0.5% of the construction cost), NEMA fees, and NCA registration.
-
Contingency Fund (5-10%): Market volatility, unexpected soil conditions, or minor design changes demand a reserve. We strongly advise setting aside 10% of the total construction cost to cover contingencies.
-
Utility Connections: Budget separately for the costs of bringing water (borehole/connection), power (transformer/connection), and sewer infrastructure to your site.
The Centimax Value: Why You Pay for Quality Design
The cost of building materials for a poorly designed house is the same as for a well-designed house. However, a poor design:
-
Costs more to run: Poor light and ventilation raise utility bills.
-
Wastes space: Unnecessary hallways and complex shapes increase the square meter count without increasing usable space.
-
Sells for less: Buyers pay a premium for the architectural drama of a double volume entry and the functionality of a well-zoned layout.
