To get the estimated cost of construction for flats in Kenya, we will first need to identify the target market.
The target market is divided into 3 classes
1. High income earners
2. Middle income earners
3. Low income earners.

High income earners:

Projects in this range are located in areas such as Hurlingham, Kileleshwa e.t.c
The land location must be in a very prime area, near a tarmac road and in close proximity to CBD.
Construction cost is estimated at a minimum of KES 35,000 per square meter.
The house size is mainly 2 ,3 and 4 bedroomed, with a minimum size of 100 m2.
The two bedroomed unit will cost approximately KES 3.5m to construct.

Middle income earners:

Projects targeting this range are located in areas such as Umoja, Kitengela, Ngong, Kikuyu, Ruiru. Generally, the areas are located around 25 to 40 km from CBD and are in close proximity to tarmac roads.
The house size is mainly 1 and 2 bedroomed with a floor plinth area of approximately 35m2 for the 1 bedroomed and 60m2 for the 2 bedroomed.
The average construction cost per square meter for this type is KES 25,000.
The 2 bedroomed unit will cost approximately KES 1.5m to construct.

Low Income earners:

Projects targeting this category of people are located in Kayole, Ruai, and in most towns at a distance of over 1 km from the main tarmac road.
The house type is mainly single and double rooms, self contained or sharing a communal bathroom facility.
The construction cost is approximately KES 20,000 per square meter.
A double room of 25 m2 will cost KES 500,000 to construct.


The construction cost estimates include labor, materials and professional fees.
The actual cost of construction is derived from the actual agreement that the land owner has with a building contractor. This amount varies from contractor to contractor depending on several factors.


Professional fees are constant and are set by the Kenyan Laws.
Chapter 525 of the laws of Kenya guide Architectural and Quantity Surveying Services.
Chapter 530 of the Laws of Kenya guide Structural, Civil, Mechanical and Electrical services.
Architectural fees are charged at 6% of the total cost of construction.
Quantity Surveying fees are at 3% of the total cost of construction.
Engineering fees vary between 1.5% to 3% depending on the complexity of involvement.


6 units on 0.5 acre plot in Kiambaa, Kiambu county.
The best target for this region is the Middle income earning class.
Therefore, the 6 units will cost 6 units x 60m2 x KES 25,000=KES 9,000,000.00.
The Architectural fees for full service from design until construction supervision to completion will be 6% x KES 9,000,000=KES 540,000.

  1. Great insights here. A point of clarification though. I think the minimum cost of construction for a house with basic finishes should be pegged at Kshs. 40,000 per SM. I think of late with the inflation that’s going on, it’s safe to work with that figure rather than the Kshs. 25,000 – Kshs. 35,000 figure.

    1. Hi Kbaab. Construction cost is determined by the house owner’s choice of the materials to be used. This is classified in 3 categories-low cost, middle and high cost materials.Each category has an average cost per m2. The figure of 25-35,000 per s.m . is for middle to high cost finishes. This ammount will increase in tandem with the inflation.

    2. Its wiser to supervise your own house because there is too much corruption involved in the building materials, Better build the house step by step and buy the materials yourself,, be there whenever there is material buying, Never trust nobody with your money,The building estimates benefits just the builders, the owners just cry, Keep sending money and its never enough , the materials bought never corresponds with the money asked , cheap quality materials used, poor drainage systems done, poor indoor work done , , Phone calls never picked to discuss the projects, , i cant advice anybody to go through this, Better build as you observe, it does not matter how long it take, but be there, It costs less and you get what you love, no fights, no quarrels, and one is happy and can only, Dear sir&madam reading this comment, can you please correct me if am wrong

      1. I want to be challenged because of my reply a few minutes ago,, . i could be convinced to take a risk,, and work with FRANCIS, in my next project, my plots are in Thogoto area,, Once bitten twice shy

        1. hi. Best is to use best practice methods that have been used the world over for hundreds of years on how to achieve building quality. There are no shortcuts. You will need to hire a registered architect to manage the project. Also hire a certified contractor through best practice methods of selection. This way you get good quality. Any other way is trying to reinvent the wheel and might not be successful.

          1. True Bwana architect, but still i tried to buy a house the other day in one of the popular middle income areas and i could clearly see evidence of poor quality materials used in the final finishing(sinks, taps, doors, toilets, etc) some were already rusting/peeling off even though the houses were basically new and still on sale- (Maisonettes mark you). so is it that the developers wanted this level of poor quality materials used may be due to cost issues, or the consultant engineers didnt check on the quality? Am an engineer myself and i could easily see these faults. But still professionals are vital. But as an owner , its good to be there with your consultants all the way.

        2. Hi Ann, I am with you on that one. If you have the uwezo, be there. I have over time used family and nothing seems to materialise, just fights and heartaches not to mention losing money. They just do their own things and your kiwanja is still there. I would talk to someone who has used profesionals to get their plots built and gather their thoughts. Goodluck

          1. lynne very correct on tht my first building used family but 2nd 3rd did it myself by use of professionals in the industry

  33. Hi, Francis,

If this is something you can offer am willing to go for the joint venture agreement.
    I look forward to hear from you to the earliest.


  34. Good morning. Well this is such a nice and informative forum and thank you Arch. Francis a space where potential developers can be able to get eye opening information and possibly a way forward on how to proceed with their developments. I am in the quantity surveying profession and from what i have gathered from above comments; cost of development is a major concern for most developers. I wish there was a way we could help all these hardworking Kenyans who wish to provide decent housing and on the other have make a sound investment. From a quantity surveyor’s perspective there are a few tricks to enable a potential developer deliver an affordable construction at its best value. Let’s divide this developer into two categories as follows:

    1. A developer who will would like to build for themselves
    2. A developer who would source out the services of a contractor.

    So, how does developer 1 get to put up a development that is affordable and of quality?
    I. You will require properly and complete designs from a registered architect and engineers.
    II. You will also need what we call a material schedule which details the quantities of materials you require during construction for your cost planning purposes.
    III. Another tool is the Bills of quantities which are vital since you can use them to engage a contractor on labour only contracts since the BQ details what needs to be done.

    Developer No.2 – one who sources the services of a contractor.
    For this type of a developer, the following tools are vital in ensuring that you put up a development that is cost effective, affordable and time cautious.

    I. You need complete designs from the architect and engineers to avert future changes in designs that lead to cost variations.

    II. From the above designs you need complete and detailed bills of quantities from a competent quantity surveyor. The quantity surveyor will provide you with accurate estimates for your project and also guide you through the best practices of sourcing for a competent contractor and at the best rates in the market.

    III. You will need to seek supervision services from the same architect, engineers and the QS to ensure that the contractor does not cut corners and delivers as intended.

    Finally, for all those seeking for a close to accurate idea of how much it would cost to put up a development with up to date market rates, it is much possible if you have the architectural designs ready or have a building resembling yours which could be used in a comparative cost estimate.

  35. Hy…the KSH1.5M that you have indicated for the case of the middle income earners is it the cost of constructing one two bedroomed house only?
