Building a house in Nigeria is no small feat. Just the cost of laying the foundation blocks could scare most people away from taking that bold step to own a house.
If you’re reading this, I believe you’re not one of those people and you’ve decided to start the project and you’re looking for information as to how much it will cost you to build 4 flats in Nigeria.
Well, I’ve got you covered. Read on to find out more.
Cost of Building 4 Flats in Nigeria
Estimating the cost of building a house is really difficult as there are many ways a house can be built. The abundance of designs means that a rough estimate could be too small or too large to cover the entire cost of constructing the building.
Before I provide an estimate, I’d love you to understand the type of building I’m talking about here.
Probably, the reason you’re building 4 flats is that you want to rent it out. When it comes to building houses for rent, the cost of constructing the building usually determines the rent to be charged.
You don’t want to go too cheap on construction or the walls will crack and the house will collapse after a few years. And you don’t want to spend too much so that the cost of rent won’t chase away potential tenants.
Whatever the reason that made you decide to construct 4 flats or whatever budget you have, this estimate should provide you with a clear view of what to expect.
The estimate is based on 4 flats of 3 bedrooms each. Depending on how you choose to build yours the cost may be higher or lower than what you will actually get.
Note: the cost of building materials is on the increase. The prices of materials used for this estimate might be slightly higher than what you’ll get on the market.
I’ll assume you’ve already paid for and secured the land, so I’ll leave the cost of acquiring the land out of the quotation.

Cost of Decking in Nigeria
The proposed building is a storey building of 4 flats. The building you might want to build could be a bungalow of 4 units, which means you won’t need this estimate.
However, if you’re going for a storey building, you could spend between 2 to 3 million for reinforcement bars, wood, concrete, electrical (conduit work), plumbing (conduit work), and workmanship.
Other Costs to Consider
Fencing: 300,000 – 500,000 (including the designs)
Plastering would cost you more than a million, depending on what you want. You’ll also have to consider PVC ceilings for the rooms, POP ceilings for sitting room, floor tiling, aluminum windows, burglary proof for windows, iron doors (entrance doors and internal doors), fittings, wirings, roofing, plumbing, and labor.
The costs of building operations are based on your taste and the type of materials you plan to use on the building.
Overall, the cost of building 4 flats of 3 bedrooms in Nigeria should cost you between 30 and 70 million. This includes the pre-cost of designs and the actual cost of building the structure itself.
The price of materials and the type of materials you choose to go for are very important factors that determine how much it will cost to erect your building. Ensure you ask a number of builders for the prices of materials before going ahead with any quotation from your architect.
