House Plans in Kasarani, Roysambu and Githurai: Rental Apartments, Bedsitters and Family Homes Along Thika Road

House plans in Kasarani are mostly about one thing: rental income. Kasarani, Roysambu, Zimmerman, Githurai and the Kahawa estates along Thika Road form one of Nairobi's densest rental markets. Students from Kenyatta University and other colleges, young professionals and growing families all need affordable homes close to the superhighway. Consequently, investors build apartment blocks, bedsitters and mixed-use buildings, while families build maisonettes in quieter estates such as Mwiki and Clay City.

This guide covers house plans and building advice for Kasarani, Mwiki, Clay City, Roysambu, Zimmerman, Githurai 44 and 45, Kahawa West, Kahawa Wendani and Kahawa Sukari. We explain the best rental and family designs, zoning, parking, water, approvals, costs and how to keep tenants happy.

Why Build Along Thika Road?

Strong Rental Demand

Thousands of students and workers rent along Thika Road. Therefore, well-designed units rarely stay empty for long.

Excellent Transport

The Thika Superhighway carries buses and matatus to the city in minutes outside peak hours. Moreover, the Northern and Eastern Bypasses link the area to Ruiru, Ruaka and JKIA.

Amenities

Malls such as Thika Road Mall and Garden City, the Kasarani sports complex, universities, hospitals and schools serve residents. Consequently, the area attracts tenants of all incomes.

Plots for Every Budget

Plot prices vary from affordable in Githurai and Zimmerman to higher in Roysambu and Garden City's surroundings.

Areas and Their Best Designs

Kasarani, Mwiki and Clay City

Kasarani combines rentals near the main roads with family estates in Mwiki, Clay City and Hunters. Consequently, maisonettes suit quieter estates, while apartments suit main roads. Our Kasarani apartments design offers 20 units over five floors. See house plans in Kasarani.

Roysambu and Thome

Roysambu is a busy hub next to Thika Road Mall. Therefore, apartments and mixed-use buildings dominate. Meanwhile, Thome and nearby estates offer family homes. See house plans in Roysambu.

Zimmerman

Zimmerman is dense, with multi-storey flats on small plots. Consequently, efficient rental blocks with bedsitters and one bedroom units perform well.

Githurai 44 and 45

Githurai is one of the densest rental areas in Nairobi and Kiambu. Therefore, four- and five-storey blocks with shops below are common. Our Githurai rentals design fits 32 units on a 50×100 plot.

Kahawa West, Kahawa Wendani and Kahawa Sukari

Kahawa Wendani serves Kenyatta University students, while Kahawa West is a dense rental area. Meanwhile, Kahawa Sukari offers family homes. Read about student hostel plans in Kenya.

More Neighbourhoods Along Thika Road

Hunters, Seasons and Sunton

Hunters, Seasons and Sunton, off Kasarani–Mwiki Road, mix maisonettes, bungalows and low-rise apartments. Consequently, they suit both families and investors. Moreover, their location near Thika Road Mall and the sports centre makes them popular.

Lumumba Drive and Roysambu's Back Streets

Behind Roysambu's busy roundabout, areas along Lumumba Drive are lined with apartment blocks. Therefore, efficient two and three bedroom units with parking suit the market.

Kamiti Road and Kahawa

Along Kamiti Road, older estates and new rentals sit side by side. Similarly, the areas around Kahawa Barracks and Kahawa Sukari offer family plots with good access to the Northern Bypass.

Mwihoko and Githurai Kimbo

Further north, Mwihoko and the areas between Githurai and Ruiru offer more affordable plots. Consequently, home-plus-rentals compounds and smaller apartment blocks suit them. Read about house plans in Ruiru, Juja and Thika.

The Nairobi–Kiambu Boundary

The Thika Road corridor straddles Nairobi and Kiambu counties. For example, Kasarani, Roysambu and Zimmerman fall under Nairobi City County, while parts of Githurai 45, Kahawa Wendani and Mwihoko fall under Kiambu County. Therefore, the approval process, zoning rules and fees depend on which side of the boundary your plot lies. Consequently, we confirm the county and its rules before design. Read about building plan approval costs by county.

Typical Plot Sizes and What Fits

Most plots along Thika Road are 40×80 or 50×100, with some smaller subdivisions in Githurai and Zimmerman. On a 40×80 plot, a three- or four-storey block with 9 to 16 units, or a 3 bedroom maisonette, is typical. Meanwhile, a 50×100 plot can hold 12 to 32 units, depending on zoning and unit sizes. Similarly, quarter-acre plots in Kasarani and Kahawa Sukari can host larger apartment blocks or townhouse compounds. Browse 40×80 plot house plans and 50×100 plot house plans.

The Northern Bypass Effect

The Northern Bypass connects Thika Road at Roysambu to Ruaka, Kiambu Road and Kikuyu. Consequently, it has boosted demand in Roysambu, Kahawa and the areas towards Ruaka. Moreover, it gives residents quick access to Gigiri, the UN complex and western Nairobi without passing through the CBD. Therefore, plots near bypass junctions are attractive. Read about house plans in Ruaka, Kikuyu and Limuru.

Designing for Noise and Dust

Thika Road and its feeder roads are busy and noisy. Therefore, place bedrooms away from main roads, use solid walls and well-sealed windows, and plant trees or hedges along boundaries. Moreover, balconies facing quieter courtyards make units more pleasant. As a result, tenants rest better and stay longer.

Popular Designs Along Thika Road

Bedsitter and One Bedroom Blocks

Bedsitters and one bedroom units suit students and young workers. Consequently, blocks with 20 to 40 compact units on a 50×100 plot are common. However, good ventilation, water, security and parking separate successful blocks from struggling ones. Read about apartment and rental building plans.

Two and Three Bedroom Apartments

Families and sharing professionals rent two and three bedroom units. Therefore, apartments with balconies, ensuite master bedrooms and parking attract longer-staying tenants. Our Umoja apartments and Kasarani apartments suit this market. Read about multi-storey apartment building plans.

Mixed-Use Buildings

Along main roads, shops on the ground floor with flats above earn two income streams. Our Biashara plaza combines six shops with nine apartments. Read about mixed-use building plans.

Family Maisonettes

In Mwiki, Clay City, Thome and Kahawa Sukari, 3 and 4 bedroom maisonettes suit families. Our Kilimani maisonette and Syokimau maisonette are popular. Browse maisonette house plans.

Home Plus Rentals

Many owners build a family home with a few rental units in the same compound. Consequently, rent helps pay the mortgage or school fees.

Zoning, Density and Parking

Nairobi City County sets plot coverage, plot ratio, floors and parking rules for each zone. Therefore, the number of units depends on your zone. Moreover, parking often limits density on 50×100 plots, so stilt parking is common. Read about garage, carport and driveway designs.

Water, Power and Sanitation

Dense rental blocks use a lot of water. Therefore, large underground tanks, booster pumps, rooftop tanks and boreholes are essential. Moreover, individual prepaid meters avoid disputes. Similarly, sewer connections or adequate treatment systems are required. Read about water and power planning for Kenyan homes.

Soil Conditions

Parts of Kasarani and Githurai have black cotton soil, while others have firmer ground. Consequently, multi-storey blocks need a soil investigation and properly designed foundations. Read about foundation designs in Kenya.

Fire Safety and Structure

Multi-storey rental blocks must have protected stairs, fire exits, extinguishers and sound structures. Unfortunately, some poorly built blocks in dense areas have collapsed in the past. Therefore, use registered engineers, approved drawings and quality materials, and supervise construction closely. Read about MEP drawings in Kenya.

Designing Efficient Bedsitters

A good bedsitter feels larger than its size. Therefore, place the bathroom near the door, the kitchenette along one wall and the sleeping area near the window. Moreover, a small balcony or large window brings light and air. Similarly, built-in shelves and a wardrobe save floor space. Consequently, a 16 to 20 m² unit can feel comfortable and attract tenants who stay. Additionally, separate prepaid meters for power and water keep billing simple.

Designing for Tenant Mix

Mixing unit types spreads risk. For example, a block with bedsitters on upper floors, one bedroom units in the middle and shops on the ground floor serves students, workers and traders. However, noise and security must be managed, with separate entrances for shops and residents. As a result, the building earns from several markets.

Building Safely in Dense Areas

Dense areas bring construction challenges. For instance, narrow access roads make deliveries difficult, neighbouring buildings sit close to boundaries and excavation can affect nearby foundations. Therefore, plan construction logistics carefully, protect neighbours and supervise work closely. Moreover, insist on concrete cube tests and inspections before each slab pour. Read about structural drawings and bills of quantities.

Redeveloping Older Homes

Some older bungalows in Kasarani and Roysambu sit on plots now zoned for higher density. Consequently, redeveloping them into apartments can multiply rental income. However, check zoning, demolition permits and tenant notices first. Read about renovation and extension plans in Kenya.

Common Mistakes in Rental Blocks

Too Many Units, Too Little Parking

Overcrowded blocks without parking struggle to let and may be rejected. Balance units and parking.

Weak Water Supply

Water shortages drive tenants away. Plan large storage and a borehole if possible.

Poor Ventilation

Dark, stuffy units rent slowly. Provide windows and cross-ventilation.

Cutting Structural Corners

Weak structures endanger lives. Use registered engineers and supervise every pour.

Financing Rental Projects

Many investors fund rental blocks in phases. For example, they build two floors, let them, then add floors with rental income or a SACCO loan. Therefore, design the structure for the final height from the start. Read about mortgage and SACCO loan house plans.

Costs of Building Along Thika Road

In 2026, rental blocks typically cost about KSh 40,000 to 55,000 per square metre, depending on finishes, floors and lifts. Typical figures are:

Our design fees for apartments fall within KSh 30,000 to 76,500 for many projects, with larger blocks quoted individually. See our pricing page and use the building cost calculator.

Keeping Tenants Happy

Tenants stay longer in well-designed buildings. For example, reliable water, secure entrances, good lighting, clean common areas, adequate parking, drying space and fast repairs all matter. Moreover, natural light and ventilation make small units feel larger. Consequently, vacancy rates fall and rents hold up. Additionally, a caretaker's room and CCTV improve security. Read about home security design in Kenya.

Landmarks and Neighbourhood Character

Landmarks shape demand along Thika Road. For example, Thika Road Mall, Garden City Mall, the Moi International Sports Centre in Kasarani, Kenyatta University, USIU-Africa and the Roysambu roundabout all influence where tenants want to live. Similarly, proximity to the superhighway's bus stops drives rents. Consequently, plots within walking distance of these landmarks earn more.

Planning a Rental Project Step by Step

First, confirm the county, zoning, plot coverage and parking rules for your plot. Next, study the local rental market: who rents nearby, which unit sizes let fastest and what rents they pay. Then commission a soil investigation for multi-storey buildings. After that, design the unit mix, parking, stairs, water storage and fire safety together. Subsequently, prepare structural drawings and a BQ, and secure approvals. Finally, build with a registered contractor and independent inspections before every slab pour. Consequently, your building is safe, approved and ready to let.

Management planning also matters. For instance, decide early whether you will manage the block yourself, hire a caretaker or use an agent. Similarly, plan rent collection, maintenance and security. As a result, the building runs smoothly from the first tenant.

Key Takeaways

Kasarani, Roysambu and Githurai offer strong rental demand and excellent transport links. However, density rules, parking, water supply and structural safety need careful attention. Therefore, design efficient units, plan parking and water generously, and build with registered professionals. As a result, your rental investment earns steadily for years.

Common Mistakes to Avoid

Rental developers in this area often make expensive mistakes. For example, some build more floors than zoning allows, and the county later halts or demolishes the building. Others skip the soil test or the structural engineer, putting tenants at risk. Similarly, too little parking and water storage frustrate tenants and raise vacancy. Moreover, poor finishes increase maintenance costs. Therefore, confirm zoning, engage registered professionals, plan parking and water, and choose durable finishes. As a result, your building stays full and profitable.

A Note on Unit Mix

Choosing the right unit mix drives returns. For instance, students near Kenyatta University and the USIU area prefer bedsitters and one bedroom units, while families along Thika Road seek two and three bedroom apartments. Therefore, study nearby buildings and their vacancy rates first. Moreover, mix sizes to spread risk. Consequently, your building fills quickly and stays full.
