The One room construction cost can vary widely based on several factors, including location, materials used, labor costs, and the specific requirements of the room.

Whenever anyone decides to construct a house or room he will definitely want to know that construction before allotting or starting the construction. This is essential to know the approximate cost of construction of one room before starting construction. This is also known as an estimation. The estimation of work is done due to the following reasons,

1. To know the cost of Construction.
2. To check the Finacial budget
3. To take a loan from a bank.
4. To compare contractors’ costs.

Estimation is the process of calculating material quantity and their cost to know the cost of construction. By estimating or calculating the one room construction cost in advance you can be going to save lots of money that contractors steal from you because you don’t know the exact cost of work.

This article will show you how to calculate quantities of materials like brick, cement, sand, Steel, and tiles with their cost.

One Room Construction Cost (10*10)

The following is methods of calculation one room construction cost and one room building materials cost Suppose there is a 10*10 room construction cost in India as shown in fig.

For this one room, we want to calculate the cost of construction and material quantities. List of quantities to be calculated,

1. Brick Work – Nos. of Brick, Cement Quantity, Sand Quantity in Mortar.
2. Concrete Work – Concrete quantity in column, beam, and slab.
3. Reinforcement quantity and cost.
4. Tile flooring cost and quality.
5. Labor Work and Cost.

Let’s calculate each quantity one by one, but before we start estimation first you need to know some important conversations as follows.

1 m = 3.28 ft or 3.28 ft = 1 m

1 ft = 12 inch or 12 inch = 1 ft

To convert ft to meter, divide ft value by 3.28 For example, value is 10 ft then the (10/3.28) = 3.05 m.

Similarly, to convert inch-to-meter multiple-inch values with 0.0254

for example, Value is 9 inch then (9 x 0.0254) = 0.23 m (230 mm).

1 Room Building Material Cost (10*10)

1. Brick Work

Brickwork is generally done at the outer edge of the room and above the slab as a parapet wall. Brick wall mainly has two thicknesses full brick and half brick.

Full brick = 9 inches (Used as the main wall) Half Brick = 4.5 inches (Used as a partition wall or Inner wall)

Here, the length of the wall = 10 ft (3.05 m), ( 10 ft / 3.28) = 3.05 m

Similarly, Width of wall = 9 inch (0.23 m), (9/0.0254) = 0.23 m There are 4 walls having the same length 10 ft. Quantity of Brickwork = 7.65 m3

a) Brick Work in Parapet

There are two walls having different lengths, so we name them short walls and long walls. Short wall length = 11′ 6″ (11(6/12) / 3.28) = 3.50 m. Longwall length = 13′ (13′ / 3.28) = 3.96 m. Height of the parapet is the same for both = 3′ (3 ft / 3.28) = 0.90 m.

Total Brick Work = Brickwork in the superstructure + Brickwork in the parapet wall

Total Brickwork = 7.65 m3 + 0.71 m3 Total Brickwork = 8.99 m3

b) Deduction of Doors and Window Quantity

When calculating the brickwork in the superstructure, we have also calculated the quantity of door and window volume that we have to deduct from the brick quantity.

c) Nos. of Bricks, Cement, and Sand Quantity and Costing

Total Cost of Brickwork = Rs. 28192

2. Concrete Quantity in Column, Beam, and Slab

Column Size = 9″ x 9″ (0.23 m x 0.23 m) Beam Size = 9″ x 12″ (0.23 m x 0.30 m) Slab, Length = 11’6″ ( 11(6/12) / 3.28) = 3.50 m Width = 13′ (13/3.28) = 3.86 m

Total Concrete Volume = 2.87 m3

Ready mix concrete (RMC) cost for M-20 Grade of Concrete = 3500 Rs. / m3

Cost of Concrete = 2.87 x 35000 Cost of Concrete = Rs. 10,045

3. Reinforcement (Steel) Quantity and Cost

Generally, Steel quantity in a column, beam, and slab reinforcement is considered to be around 1% to 2% of the volume of concrete.

Volume of Reinforcement (Steel) = 1% of Volume of Concrete Volume of Reinforcement (Steel) = 0.01 x 2.87 = 0.029 m3 We know the density of steel = 7850 kg / m3 From the density and volume of steel, we can calculate the weight of steel in kg. Weight of steel = 0.029 m3 x 7850 kg/m3 Weight of steel = 225.54 kg A normal rate of construction steel is about 45 to 60 Rs. per Kg in the market. So, if we take 50 Rs. / kg rate, then Cost of Steel = Weight of Steel x Rate of Steel = 225.54 x 50 Cost of Steel = Rs. 11,277

4. Flooring Tiles Quantity and Cost

The inside room area is 10 ft x 10 ft where tile flooring is required. If Size of Tile = 18″ x 18″ (0.45 m x 0.45 m)

First, Calculate the area of the room where tile flooring is to install. Area of Room = 10 ft x 10 ft = 100 sq ft Suppose, you have chosen a tile that has a rate of Rs. 25 / sq ft. Cost of Tile Flooring = 100 x 25 = Rs. 2500

5. Labor Cost Calculation

The labor work rate in the market starts from 170 rs./sq ft to 500 rs./sq ft depending upon the nature of the work. Total Construction area here = 11’6″ x 11’6″ ( 11.5 ft x 11.5 ft) = 132.25 sq. ft. Cost of Labor = 132.25 x 200 Cost of Labor = Rs. 26,450

6. Total Cost of Construction of One Room

Cost of Materials = Rs. 52,015 Cost of Labor = Rs. 26,450

(Note: In this estimate plastering, skirting, color, etc finishing quantities are not included. Therefore the cost of one room may increase by 10,000 to 15,000 rs.)

Total Cost of Construction of One Room,

= 52,015 Rs. + 26,450 Rs. = 78,465 Rs. one room building material cost is around 78,465 Rs. Read More:
