Do you want to know the cost of building a 3 bedroom bungalow in Nigeria? This article is for you. So many people visit the web to know the cost of building a 3 bedroom bungalow in Nigeria but get disappointed most of the time. Only a few articles exist on the subject topic and rarely have details. In this article, you would get full details on the cost of building a 3 bedroom bungalow in Nigeria.
Most times when people hear the cost of building a 3 bedroom bungalow in Nigeria from friends, they get scared. The cost they get to hear, run into tens of millions at some point. Honestly, you can build a 3 bedroom bungalow for as much as N50,000,000, or as low as N5,000,000. Sometimes the estimate even goes below the latter. This cost is affected by a number of factors ranging from:
- Location of the property.
- Cost of building materials.
- Quality of building materials.
- Charges of professionals as it varies.
It may cost you more when building your own 3 bedroom bungalow but below is the estimated cost for a standard 3 bedroom bungalow in Nigeria. The breakdown involves the cost of the actual construction and not the preliminaries to the construction.
Before you begin construction, you must have acquired a piece of land. See DOCUMENTS REQUIRED FOR LAND PURCHASE IN NIGERIA. Also, before the construction process, are steps needed to be taken in building a house in Nigeria. These steps involve architects and related building engineers. Look at the processes for BUILDING A HOUSE IN NIGERIA.
Cost of Building a 3 Bedroom Bungalow in Nigeria 2021
Before you dig earth, make sure you have all required APPROVED documents for the construction process, viz a viz:
- Architectural drawings.
- Structural drawings.
- Mechanical drawings.
- Electrical drawings.
Some people break earth without some of these drawings and hope everything turns out fine. That is a wrong mentality. Please follow the right process.
In calculating the cost of building a 3 bedroom bungalow in Nigeria, it is advisable to breakdown the construction process into stages. This is the norm and is actually helpful in planning your progress. For a bungalow, we can split the construction stages into:
- Foundation (German floor) / Soak-away Stage.
- DPC to lintel level Stage.
- Roofing Stage.
- Plastering / Finishing Stage.
Cost of Foundation (German Floor) / Soak-away Stage
This is the first stage of construction and it includes setting out, digging, concrete work, block laying, backfilling, and flooring as the processes in this stage.
Material Requirements for Setting-out with profiles
- 4 pieces of 1 x 12 plank @ NGN 1,200 each plus NGN 800 (for dividing each into 5 (@ NGN 200 each) = NGN 5,600
- 4 bundles of Pegs @ NGN 1,200 each = NGN 4,800
- 2″ and 3″ Nails = NGN 1,200 worth of nails
- 4 bundles of rope @ NGN 200 each = NGN 800
- Labour = NGN 5,000
Estimated cost of setting-out = NGN 17,400.
Material Requirements for Digging / Excavation
- We will need some diggers and shovels for the job. These tools can cost about NGN 2,000 to rent.
- Labour = NGN 10,000
Estimated cost of digging = NGN 12,000.
Material Requirements for Concrete work / Blinding
For a standard foundation of 150 mm base-thickness, assuming 0.45m (breadth or height) and 85.5m (entire length) = 5.77125 m3
- 10 bags of cement @ NGN 4,600 each = NGN 46,000
- 20 tonnes of sand x 2 = NGN 80,000
- 20 tonnes of Granite = NGN 140,000
- We don’t need reinforcements (Iron bars) because the soil is good, firm, and dry.
- Liters of water as needed.
- Labour = NGN 25,000
The estimated cost of concrete work = NGN 291,000.
Material Requirements for Laying Foundation Blocks
Using 9-inch blocks and laying 4 coaches, you will need
- 12 bags of cement @ NGN 4,600 each = NGN 55,200
- 644 pieces of 9-inch vibrated blocks (including 10 percent wastage) @ NGN 200 each = NGN 128,800
- Plumbing work = NGN 25,000
- The remaining sand from concrete work will be used here.
- Labour = NGN 35,000
The estimated cost of laying foundation blocks = NGN 244,000.
Material Requirements for Filling
I suggest digging the soak-away and septic tank alongside making the foundation so that the soil dug up from the soak-away pit, septic tank, and well can be used for backfilling. This will save you the cost of buying some tons of sand for foundation filling and also save you the cost of clearing the dug-up soil where it is unused.
After filling the foundation, water it for about 10 hours and leave it for days (or some weeks) before flooring for natural compaction. In the end, you might need to buy just a few tons of sand if the soil dug up from the well and septic tank is not enough.
Assuming you buy:
- 3 nos 20 tonnes laterite (fairly clayey) at NGN 18,000 = NGN 54,000
- Labour = NGN 10,000
Estimated cost of filling foundation = NGN 64,000
Material Requirements for Foundation Casting / Flooring
- 25 bags of cement @ NGN 4,600 = NGN 115,000
- Waterproof / nylon = NGN 15,000
- The remaining granite and sand from concrete work will be used here.
- Labour = NGN 18,000
Estimated cost of flooring = NGN 148,000
Material Requirements for Septic Tank, Soak-away pit and Well
The septic tank, soak-away pit, and well should be constructed first in order to have water for the work and sand for filling the foundation later.
- 700 pieces of 6-inch vibrated blocks @ NGN 170 / block (for a septic tank of 3m x 3m x 3m) = NGN 119,000.
- 22 bags of cement @ NGN 4,600 = NGN 101,200 (including plastering).
- Number of well-rings as required.
- Sand and granite from concrete work will be used here.
- Labor for septic tank, soak-away pit, and well = NGN 80,000
The estimated cost of constructing both the septic tank, soak-away, and well = NGN 300,200.
Total Estimated Cost for this stage = NGN 1,076,600 (excluding the cost of wellrings).
Cost of Construction From Damp Proof Course (D.P.C) To Lintel Level
This is the next stage in the construction process and begins where the German floor ends. It covers the main block work including wall partitions for the various spaces in the house. The materials listed below are just estimates of what you get in a modest 3-bedroom flat. Again, ensure you get a Bill of Quantities for your building plan as that’s the only way to know the exact material requirements for your house. This stage ends at the roof level.
Material Requirements and Labour for Block work
- 2100pcs of 6-inch stone dust vibrated blocks @ NGN 170 = NGN 357,000.
- (The cost increases when you use 9-inch blocks)
- 15 tonnes of sharp sand = NGN 40,000
- 30 bags of cement @ NGN 4,600 = NGN 138,000
- Labour = NGN 120,000
Estimated cost of block work = NGN 655,000. (This includes the two coaches of blocks after lintel)
Material Requirement for Lintel Casting
- 20 length of 12mm rod @ NGN 2,100 / length = NGN 42,000
- 10 length of stirrups @ NGN 500 / length = NGN 5,000
- 35 length of 1 x 12 x 18 wood @ NGN 1,700 / length = NGN 59,500
- Nails plus wire for binding = NGN 13,000
- 8 bags of cement @ NGN 4,600 = NGN 36,800
- Remaining sand will be used here.
- The remaining granite from concrete work is used.
- Labour plus carpenter = NGN 30,000
The estimated cost of the lintel level = NGN 186,300
Estimated Total Cost for this stage = NGN 841,300.
Cost of Roofing 3 Bedroom Bungalow Stage
The cost of roofing varies with the type of roofing materials and design you choose to use. The cost given below represents 0.45 mm thick aluminum roofing sheets. The true cost of all stages remains that shown on the bill of quantity document.
Material Requirements for Roofing
- 320 length of 2 x 3 x 12 wood @ NGN 450 = NGN 144,000
- 45 length of 2 x 6 x 12 @ NGN 840 = NGN 38,250
- 25 length of 1 x 12 x 12 wood @ NGN 1,400 = NGN 35,000
- 1/2 bag of 2-inch nails @ NGN 5,800 = NGN 2,900
- 11/2 bags of 3-inch nails @ NGN 6,000 = NGN 9,000
- 1/2 bag of 4-inch nails @ NGN 6,500 = NGN 3,250
- Aluminium (0.45mm thick) roofing, transportation and Labour = NGN 685,900
Total Estimated Cost for the roofing stage = NGN 918,300.
Cost of Finishing Stage
This stage includes plastering, wiring, plumbing, fixing of windows, doors, tiles, and other essentials. The cost here varies regarding the quality of materials you use. Below is an estimate for a very modest finishing.
Material Requirements for Electrical works
- Wires, Pipes, Conduit Boxes, etc = NGN 400,000
- Material Requirements for Mechanical and Plumbing Works
- Kitchen sink, Pipes, WC, Washing Hand Basin, Overhead Tank, Shower, etc = NGN 500,000
