Cost guide / Nairobi / 2026
A rate per square metre is the beginning of the cost plan, not the answer.
Indicative apartment construction ranges for early Nairobi feasibility - with the inclusions, exclusions, design drivers, and additional allowances that turn a headline rate into a development cost plan.
Published 1 July 2026 · Early feasibility only · Rates exclude land, finance, tax, and sales costs.
2026 benchmark view
Use a range wide enough to admit what you do not yet know.
AAK published 2025 benchmarks of KES 68,837 per m² for standard low-rise apartments and KES 90,013 per m² for luxury apartment blocks. KNBS reported that the overall construction input price index declined 0.52% quarter-on-quarter in Q1 2026, with annual construction-input inflation at 0.39%.
01
Standard low-rise apartments
KES 70,000-85,000 / m² GFA
AAK 2025 published benchmark: KES 68,837 / m²
Straightforward low-rise blocks, efficient structure, limited vertical transport, standard finishes, and ordinary site conditions.
02
Mid-market multi-storey apartments
KES 85,000-105,000 / m² GFA
The Development Playbook 2026 feasibility range
Lifts, stronger fire and services requirements, more demanding common areas, urban logistics, and a market-facing finish specification.
03
Upper-market and luxury apartments
KES 100,000-135,000+ / m² GFA
AAK 2025 luxury apartment benchmark: KES 90,013 / m²
Higher facade, MEP, finish, amenity, acoustic, security, backup power, water, landscape, and common-area expectations.
The 2026 ranges are Development Playbook working ranges for feasibility, informed by the published anchors and current input-index context. They are not tender prices or market quotations.
Define the rate
Before comparing two numbers, compare their scope.
01
Measurement basis
Gross floor area, construction floor area, or another stated measurement convention.
02
Building scope
Structure, envelope, internal finishes, MEP services, lifts, preliminaries, and contractor overheads.
03
Site scope
External works, parking, utility connections, roads, landscape, retaining, demolition, and abnormal ground.
04
Commercial basis
Location, pricing date, procurement route, design maturity, programme, taxes, currency exposure, and escalation.
05
Explicit exclusions
Land, finance, professional fees, statutory costs, contingency, marketing, sales, and operational setup unless stated.
Six cost drivers
Why two apartment blocks rarely share one rate.
Treat every adjustment as a design, procurement, programme, or site hypothesis that can later be replaced by evidence.
01
Height and structure
More floors can improve land efficiency while increasing structural, vertical transport, fire, pumping, facade-access, and logistics costs.
02
Basements and parking
Excavation, retaining, waterproofing, ventilation, fire systems, ramps, and slow construction can make basement parking one of the largest rate distortions.
03
Services and resilience
Lifts, generators, solar, water storage, boreholes, treatment, security, fire systems, data, cooling, and metering vary sharply by product and location.
04
Envelope and finishes
Glazing ratios, balconies, facade articulation, imported finishes, joinery, sanitaryware, kitchens, and acoustic performance change both cost and revenue.
05
Site and infrastructure
Slope, soil, rock, drainage, demolition, access, utility extensions, road works, and constrained delivery conditions often sit outside the headline rate.
06
Procurement and programme
Design completeness, contractor market, packaging, imported content, foreign exchange, lead times, bonds, insurance, preliminaries, and escalation affect the outturn.
Build the cost stack
The building rate is not total development cost.
The allowances shown are broad early-stage prompts, not prescribed percentages. Replace them as the design and procurement strategy mature.
Base building works
100% reference
Structure, envelope, services, finishes, preliminaries, and normal building works as defined in the estimate.
External works and utilities
5-12%
Site works, drainage, access, landscape, boundary works, utility connections, and infrastructure allowances.
Professional fees
6-10%
Architecture, engineering, quantity surveying, project management, planning, specialist design, and supervision.
Statutory and approval costs
1-3%
Project-specific allowance only; verify county, NEMA, NCA, utility, insurance, levy, and other requirements.
Design and construction contingency
5-10%
Reflect design maturity, site evidence, procurement risk, market volatility, and known unknowns.
Escalation
Project-specific
Apply to the timing and expenditure profile, not as an unexplained percentage added to the final total.
Land, finance, tax and sales
Separate
These are development costs, but they are not construction cost and should remain visible outside the building rate.

Base building works

8% of building plus external works
Statutory allowance
KES 13.6m
2% planning allowance
Contingency
KES 47.6m
7% of building plus external works
Cost before land / finance / tax
KES 796.1m
Approximately KES 113,724 / m² GFA
Sources and method
A dated benchmark is more useful than a confident one.
Rebase the model when a current project estimate, contractor return, or new official index becomes available. Never mix rates with different dates and inclusions without adjustment.

Questions / method
Use the benchmark without mistaking it for certainty.
How much does it cost to build apartments in Nairobi in 2026?
For early feasibility, this guide uses broad working ranges of approximately KES 70,000-85,000 per m² GFA for standard low-rise apartments, KES 85,000-105,000 for mid-market multi-storey apartments, and KES 100,000-135,000 or more for upper-market schemes. These are planning ranges, not quotations, and must be reconciled to a defined scope and current quantity-surveyor estimate.
What does construction cost per square metre include?
There is no universal inclusion rule. A rate may include or exclude preliminaries, external works, utility connections, lifts, backup systems, professional fees, statutory charges, contingency, escalation, VAT, land, finance, and sales costs. A useful benchmark must state its measurement basis and inclusions before comparison.
Should apartment cost be measured against GFA or saleable area?
Construction cost is normally tested against gross floor area because the contractor builds cores, circulation, plant, parking, and shared areas as well as saleable units. Revenue is usually measured against saleable area. The difference between the two is why efficiency materially affects feasibility.
Can the benchmark replace a quantity surveyor's cost plan?
No. A benchmark is a screening tool. As soon as site geometry, design, structure, services, specification, programme, and procurement become clearer, replace the benchmark with a project-specific cost plan prepared and updated by an appropriately qualified quantity surveyor.
