Building an affordable home in Kenya is possible with smart planning and design. Here’s how to construct a quality house on a budget, with designs ranging from KES 1 million to 3 million.
Understanding Affordable Housing in Kenya
Affordable housing means different things to different people. For this guide, we focus on homes costing KES 1-3 million to construct, suitable for middle and lower-middle income Kenyans.
What Affects Construction Costs?
Several factors determine your final cost:
- Location: Building in Nairobi costs 20-30% more than rural areas
- Design complexity: Simple rectangular designs cost less
- Materials: Local materials are cheaper than imported ones
- Finishes: Basic finishes versus high-end finishes
- Foundation type: Depends on soil conditions
- Labor costs: Vary by region
Budget Categories and What You Get
Entry Level: KES 1-1.5 Million
What you can build:
- 2-bedroom bungalow (60-80 square meters)
- Simple rectangular design
- Basic finishes (cement floors, simple tiles in bathroom)
- Manual water system
- Standard electrical fittings
Best for: First-time homeowners, retirement homes, rental units
Mid-Range: KES 1.5-2.5 Million

Cost-Effective Design Principles
Keep It Simple
Complex designs increase costs:
- Rectangular or square shapes use materials efficiently
- Fewer corners mean less waste and faster construction
- Simple roof design (hip or gable) costs less than complex roofs
- Straight walls are cheaper than curved ones
A simple rectangular 3-bedroom house might cost KES 2 million while a complex design of the same size costs KES 2.5-2.8 million.
Design for Future Expansion
Build a solid foundation that can support a second floor:
- Stronger foundation costs 10-15% more now
- Saves 30-40% compared to adding later
- Roof design that allows for vertical expansion
- Staircase space planned from the beginning
Optimize Room Sizes
Don’t waste space or money:
- Master bedroom: 12-14 square meters (adequate and comfortable)
- Other bedrooms: 10-12 square meters
- Living room: 18-25 square meters
- Kitchen: 8-10 square meters
- Bathrooms: 4-5 square meters
Oversized rooms increase costs without adding value.
Multi-Purpose Spaces
Combine functions to save space and money:
- Open-plan living/dining feels spacious, costs less
- Kitchen with breakfast counter instead of separate dining
- Master bedroom with en-suite maximizes privacy
- Built-in storage instead of buying furniture
Affordable Construction Materials
Foundation and Structure
Foundation options:
- Strip foundation: Most common, works for most soils, KES 100-150 per square foot
- Raft foundation: For weak soils, more expensive but necessary
- Pad foundation: For stronger soils, can be cheaper
Walling materials (cost per square meter):
- Machine-cut stones: KES 600-800 (durable, good insulation)
- Concrete blocks: KES 450-650 (standard, widely available)
- Bricks: KES 500-700 (good insulation, traditional)
- Interlocking blocks: KES 400-600 (fast construction, less cement)
Recommendation: Machine-cut stones for exterior walls (durability), concrete blocks for interior partitions (cost savings).
Roofing
Roofing materials (cost per square meter):
- Corrugated iron sheets (mabati): KES 350-600 (affordable, widely used)
- Stone-coated tiles: KES 1,200-1,800 (premium look, durable)
- Clay tiles: KES 1,500-2,500 (traditional, very durable)
- Concrete tiles: KES 800-1,200 (good middle option)
For affordable housing, gauge 30 mabati (thicker, longer-lasting) is best value. Cost: KES 450-550 per square meter installed.
Flooring
Options from cheapest to most expensive:
- Cement screed: KES 200-300/sqm (basic, functional)
- Standard tiles: KES 800-1,200/sqm (good for living areas)
- Ceramic tiles: KES 1,500-2,500/sqm (bathrooms, kitchen)
- Porcelain tiles: KES 2,500-4,000/sqm (high-end, not necessary for affordable housing)
Mix approaches: Cement in garage, tiles in living areas, ceramics in wet areas.
Windows and Doors
Cost-effective choices:
- Windows: Aluminum sliding windows, KES 3,500-5,000 per square meter
- External doors: Solid hardwood doors, KES 12,000-18,000 each
- Internal doors: Semi-solid or flush doors, KES 6,000-10,000 each
Don’t compromise on external doors and windows—they provide security and energy efficiency.

Money-Saving Strategies
Buy Materials in Bulk
Buy major materials at once for discounts:
- Cement: 10% discount on 100+ bags
- Steel: 5-10% discount on bulk orders
- Tiles: Up to 15% discount on large orders
- Sand and ballast: Much cheaper when buying truckloads
Potential savings: KES 100,000-200,000 on a KES 2 million project.
Source Materials Locally
- Stones: Buy from nearby quarries (saves transport)
- Sand: Local river sand where allowed
- Timber: Local suppliers rather than timber yards
- Labor: Local fundis often charge less
Transport can be 20-30% of material costs—minimize it.
Do Some Work Yourself
If you have time and basic skills:
- Project management: Save 5-10% contractor fees
- Painting: Easy to learn, saves KES 30,000-50,000
- Simple finishes: Installing curtain rods, towel holders
- Landscaping: Plant grass and flowers yourself
Don’t attempt skilled work like plumbing, electrical, or roofing—mistakes cost more to fix.
Build in Phases
Spread costs over time:
- Phase 1: Foundation, walls, roof, basic finishes (livable)
- Phase 2: Better finishes, built-in furniture, landscaping
- Phase 3: Solar panels, water features, premium touches
Move in after Phase 1 and complete others as finances allow.
Negotiate with Contractors
Get multiple quotes and negotiate:
- Get at least 3 quotes for comparison
- Negotiate material prices separately from labor
- Consider fixed-price contracts (you save from bulk buying)
- Include penalty clauses for delays
Common Mistakes That Increase Costs
No Proper Planning
Starting without complete plans leads to:
- Design changes during construction (very expensive)
- Material wastage
- Construction delays
- Disputes with contractors
Invest KES 50,000-100,000 in a good architect—saves much more in the long run.
Poor Site Preparation
Not understanding your site causes problems:
- Wrong foundation type (collapses or over-engineering)
- Drainage issues (flooding, dampness)
- Access problems (expensive material delivery)
Conduct soil tests (KES 15,000-25,000) before designing.
Cheap, Low-Quality Materials
Trying to save money with inferior materials:
- Weak cement that compromises structure
- Thin gauge mabati that rusts quickly
- Poor quality paint that fades or peels
- Substandard electrical cables (fire risk)
Buy from reputable suppliers even if slightly more expensive.
No Construction Supervision
Leaving fundis unsupervised leads to:
- Material theft
- Poor workmanship
- Shortcuts that compromise quality
- Cost overruns
Visit the site daily or hire a site supervisor (KES 25,000-40,000 per month).
Financing Your Affordable Home
Savings and Personal Funds
Ideally, have 40-50% of costs saved:
- Reduces financing costs
- Gives flexibility in construction timing
- Allows you to take advantage of material deals
Bank Mortgages
Most banks offer construction mortgages:
- Interest rates: 11-14% per annum
- Repayment: Up to 25 years
- Down payment: 10-20% of project cost
- Disbursement: In phases as construction progresses
Calculate affordability: Monthly payment shouldn’t exceed 30% of income.
Saccos and Cooperatives
Often have better terms than banks:
- Lower interest rates (9-12%)
- Flexible repayment
- Member dividends can offset costs
- Less stringent requirements
Check if your employer has a housing Sacco.
Government Programs
Take advantage of available programs:
- NHDF (National Housing Development Fund): Contributions earn you access to subsidized housing
- County housing programs: Some counties offer land or construction support
- Tax incentives: Mortgage interest is tax-deductible
Timeline for Construction
Realistic timelines for different projects:
2-bedroom bungalow: 4-6 months 3-bedroom bungalow: 6-8 months Two-story house: 8-12 months
Factors affecting timeline:
- Weather (rain delays by 2-4 weeks)
- Material availability
- Contractor reliability
- Your financial flow
Plan for delays—add 20-30% buffer time.
Legal and Regulatory Requirements
Approvals Needed
Before construction starts:
- Land title: Ensure it’s genuine and in your name
- Building plan approval: From county government (KES 30,000-100,000)
- Environmental impact assessment: If required (KES 50,000-150,000)
- Utility connections: Water, electricity, sewerage
Budget KES 100,000-200,000 for approvals and connections.
Building Standards
Follow National Construction Authority (NCA) standards:
- Hire NCA-registered contractors
- Use approved materials
- Follow approved plans
- Allow inspections at key stages
Non-compliance can lead to demolition or fines.
