The costs involved in a room addition include permits, labor and materials. National averages for additions range from $80 to $200 per square foot. But high-cost areas like San Francisco jump to an average of $330 per square foot. Plan your project in detail to make sure you don't get caught with a money-pit project that digs deeper into your savings or has to be abandoned because you ran out of funds.
Square Footage Calculation
Determine how much you want to add to the house in terms of square footage to establish a good estimate and starting point. For example, if you want to extend the back of the house 15 feet from the end and 25 feet across, this is 375 square feet (15 feet x 25 feet = 375 square feet). This amount times the average cost per square foot is $123,750 in San Francisco ($330 per square foot x 375 square feet = $123,750).
Breakdown of Costs
If you have a contractor, the average breakdown of a bid is typically one-third materials, one-third labor and one-third contractor profit and overhead. Keep this in mind as you take bids, and look for areas where you can save costs. One-third of $123,750 is almost $41,000. The contractor's margin is approximately 50 percent profit; meaning $20,500 is profit and the other half is overhead. If you have a contractor willing to let you manage certain things such as acquiring permits, ordering materials and coordinating delivery, you can save some money.
Factors Increasing Costs
Your costs will go up or down based on the grade of materials you choose to use in the addition. Using steel framing is more expensive than wood. A sloped lot requires further grading and foundation planning. Running plumbing and electrical lines adds costs in materials, labor and permits. Higher ceilings, bay windows and built-ins all increase the costs.
Plan According to Material Size
You an save costs if you plan your addition based on the dimensions of building materials. Essentially every saw cut and added corner costs more; a square is cheaper than a hexagon. If two-by-fours are 8 feet long, you save by building a room in multiples of 8 to reduce cuts and excess. This means that an 8-by-16-foot room is cheaper than a 10-by-15-foot room. Do the math and measure everything to see if you can live with the change in dimension, perhaps sacrificing a few square feet in the final product.

In this article, we will discuss what is the Cost of Construction of One Room or 10*10 Room Construction Cost In India and its materials estimation.
Whenever anyone decides to construct the 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 before starting construction. This is also known as an estimation. The estimation of work is done due to the owing reasons,
- To know the cost of Construction.
- To check the Finacial budget
- To take a loan from a bank.
- 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 cost of construction in advance you can definitely 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.

10*10 room construction cost in India
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,
- Brick Work – Nos. of Brick, Cement Quantity, Sand Quantity in Mortar.
- Concrete Work – Concrete quantity in column, beam, and slab.
- Reinforcement quantity and cost.
- Tile flooring cost and quality.
- Labor Work and Cost.
Let’s calculated each quantity one by one,
but before we start estimation first you need to know some important conversation 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, Length of 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.
Long wall length = 13′ (13′ / 3.28) = 3.96 m.
Height of parapet is same for both = 3′ (3 ft / 3.28) = 0.90 m.
Total Brick Work = Brickwork in 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 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.
1 room building material cost is around 78,465 Rs.
