What is a Construction Cost Calculator?

A cost calculator is a software available as an interface on our website. The software uses advanced algorithms and various other parameters required for building a house. These details help you in calculating/suggesting the approximate cost of building a house in Bangalore.

With this tool, the process of cost estimation is greatly simplified, making the task easy to perform by even a novice who does not have a technical understanding of the construction industry.

The tool requires the user to input information such as the location of the site, type of house, no. of floors, painting type, materials used in the door, window, flooring, etc. to calculate the estimated cost of a project.

The software also uses regularly updated information on the price of land, materials, labour charges, amongst other variables during the process of ascertaining the cost of building your house.

Factors Considered by the Cost Calculator:

After dedicating decades into the construction industry, the leading Architects, structural engineers, and building contractors collaborated to develop the software. This software considers the essential factors that influence the cost of a project. Let us have a look at the top eight factors considered by the cost calculator to estimate the value of a building.


The location of the site is one of the essential factors while estimating the cost as the price of land varies from one location to the other. The cost of building a house in a posh locality will be much higher than the outskirts of the city.

We have a dedicated team that continuously monitors the price of land across the city, among other information like changes in the cost of materials and labour cost.


Depending on the kind of house you want to build, the cost can vary. A residential building can be categorized into three main types – Rental, Duplex, and a Hybrid combination of both duplex + rental. A duplex house is two floors with a connecting staircase leading from within the home.

A rental house is apartments with all the facilities inside the apartment; this is constructed to rent. Depending on the type of residence, the estimated cost of the building can fluctuate.


Based on the number of floors you want to build, One can choose no of floors like G+1 G+2 G+3 or G+4.  the software calculates the materials and labor charges and uses this information to suggest the most appropriate cost of construction for your building.


The area of the site is also an important factor based on which the cost of construction increases or decreases. If the area of construction is substantial, resources required to construct the house will be more such as duration of labour on a site, the fee for hired equipment, materials, etc.

Whereas, if the area of the site is small, the resources required will be less. Hence, the cost calculator also uses the area of your site as a factor to determine the total cost of the project.

No. of BHK:

Similarly to the above factors, the number of BHK (1Bhk 2BHK 3BHK or 4BHK) you want to build also increases the cost of the house in terms of the duration the project takes and materials required.


The software has an inbuilt algorithm that decides the period it will take to complete the project based on the information you provide such as the no. of BHK, type of house, size of the plot, and the number of floors.

Depending on the duration, the tool automatically calculates the number of hours the labour force will work on the project and uses this information as a factor in the final cost.


The cost calculator app is regularly updated with data on the remuneration of labour in different parts of the city. Based on the information you provide such as the location of the plot, size of the plot, no. of floors, BHK, and type of house, the software calculates the hours and number of labour will be required to complete the project.

This information is calculated into the final cost of construction.


The software also factors the material choice and its value for flooring, door, and windows in the house.

Using these metrics, the construction cost calculator helps to determine the cost of building a house in Bangalore. For more information and assistance, you can consult one of our architect who will lay down the plans for your house.

How Architects save on Construction cost while building a house in Bangalore

In general, Architects have possessed unique creative skills and years of experience in offering benefits to a specific project. There are several different ways wherein Architects could restrict the construction costs involved in constructing a house few of which are mentioned below.

Architects save on construction


  • An authentic and reliable Architect would always make sure there are adequate air and ventilation within the interiors. It is also very helpful in reducing strain to the eyes and prevents glare.
  •  A well-equipped space containing a proper HVAC system, lighting patterns ensures our body is in a healthy condition, thereby reducing medical expenses.
  • He focuses on designing buildings that are free from falling, slipping and tripping. It is closely related to eliminating the risk factors associated with it, thereby cutting down medical costs.
  • The planned Spaces are created, which could provide easy access for the guests. It is helpful in enhancing the comfort level with optimum safety. One can save money on expensive renovations.
  • Their experience will assist the clients in improving the value and saving money via enhancing productivity and efficiency. They help in placing appropriate layouts and functionalities in an optimized way.
  • A major benefit of the personalized layout is that it allows people to divert their attention in spending quality time with their friends and relatives.
  • If spaces are properly utilized, overall square footage can be reduced and ultimately cutting down maintenance and construction expenses.


  • Architects place layouts that would minimize the gap between appliances and spots where one spends most of their time.
    One can develop a layout that is capable of harboring storage space.
  • An architect does help in locating a spot that is meant to wash and dry clothes. It is very useful in narrowing down the total distance taken to travel from one place to another.
  • Designing and developing energy efficient buildings which consume less energy.
  • Construction costs could be reduced to a great extent if the Architect laid particular emphasis on picking cost-effective materials, appropriate floor plans and simple yet elegant designs.
  • Optimum performance is ensured through cost analysis along with performance related to assembling walls and materials.


During the initial stages of creating a concept plans, the Architect concentrates on developing a rough sketch of the structure. This is helpful for the clients to keep track of the cost involved at the time of constructing a house.

Unnecessary assumptions can be avoided putting forward a systematic and up-to-date series of construction drawings.

If the client can comprehend the actual price of a project before commencement of construction, it’s helpful for them to conclude whether to proceed with the project or not. They have the option to switch over to other core spots that could bring down the cost.


Another best alternative to save money is through a reduction in up-front cost. If necessary, the client may approach the design team to execute wise decisions related to the usage of quality materials and equipment to restrict expenses.

Those who desire to limit budget may select energy-efficient materials that contribute towards huge savings in the end.

Construction supervisions are performed by Architects to make sure that the house is developed as per industry standards. Some of the other means to cut down long-term expenses are through minimizing gaps to prevent air leakage.

It is highly recommended to consult an experienced Architect or a Structural engineer to perform a site review before the purchase of land.

To ensure optimum efficiency in house design, it is essential to execute the below-mentioned ideas:

Install windows on either side of a unit to bring in adequate air and ventilation. Cross ventilation helps cut down cooling and heating expenses. Replacing galley kitchen with L and U shaped kitchen to save square footage and accommodate storage space.

Square footage can also be saved via narrowing down hallways as well as stairways. To develop an aesthetic design, integrate layers overhangs and decks at a nominal rate.


Modular construction is defined as the process through which pre-fabricated materials are used to construct or design rooms, lifts and toilets. It adds more value and improves productivity, thereby minimizing the wastage of resources.

To put into practice, proper planning and organization are required. To ensure proper construction of modular units, the concerned contractors need to interact with the project team about documentation.

Bridging the communication gap between Clients and Architects:

There should be open and effective communication between customers and architects to rectify any sorts of problems that might arise at the time of constructing a house. Architects should take into consideration the needs and requirements of the clients and act accordingly.

Factors that influence the Cost of Building a House on 20×30 30×40 30×50 40×60 40×50 30×50 50×80 Site?

Are you building your Dream house? Or is Planning to have one? Is yes then you should read this till the end.

If you are familiar with new houses being recently constructed in your locality, you can use them as references for preparing the estimates, house plans, elevations, structural drawings etc. This can a great help as a number of factors will be similar including the labour charges, raw materials, etc.

Once the final cost is prepared, the past project needs to be factored with the present construction indices.


It is well known that the bigger the house the higher the construction cost. Usually, the cost of the house is calculated per square feet.

Here are some of the items on which the overall cost is directly dependent:

  • Total square feet.
  • Slab area.
  • Bathware fittings.
  • Elevation design.
  • Structure.
  • Roofing.
  • Electrical work.
  • Walls.
  • Interior work.
  • Painting.


The house plans designed by Architects play a vital factor which determines the cost of building the house. The design structure usually includes the shape and layout.

For those whose house design includes many corners, offsets, and complicated roof lines will definitely be costing more compared to those with a simpler design wasted areas refer to the long hallways, bigger bathrooms where there is an area to stand in front of the sink and another to enter the shower instead of using the same area for both purposes.

The wasted area will result in more square footage which means more money.


The finishes and features are also one of the determining factors for the cost of a building in Bangalore. The cost can vary from those which are calculated with square footage e.g. the flooring to those counted as single-item like the fireplace or appliances. Also having more exterior wall will mean higher cost.

If you are planning to install wood like tile, granite, marble which mimics the original wood floor planks, then it will cost you more than the standard tile which comes in a consistent pattern.


The site location largely influences the cost of a building. It can either increase or decrease due to the following probable conditions:

  • Loose soil.
  • Conflicting utilities.
  • Soil conditions.
  • Sourced materials.
  • Overhead lines.
  • Drains.
  • Groundwater.
  • Road width.

At times the location of the site also becomes vital. For example, if your location is a high-value property, then you might want to build a high-value property. This will cost you more in comparison to building a low-value property in a low-value area.


Construction material cost consists of the raw materials cost, shipping charges, and taxes if any. These parameters play a significant role while determining the cost.
Along with it, the transportation of materials is also important. Whether the raw materials are available within the close proximity.

Reducing the transportation cost of the materials cost can play a big change in determining the overall budget.


Labour cost for house construction varies from Rs 250 to Rs 380/sq ft which can fluctuate from place to place or depending on the design. Proper labour cost calculation should be done. And always get ready for unpredictable scenarios. If due to some reason the project gets delayed, the probable variation in wage rates has to be included.

Generally, the cost of labour in urban areas is higher compared to the rural areas, mainly due to the higher cost of living in urban areas.


The construction process may get delayed due to unpredicted delay in the project duration by the contractor. This can, in turn, increase construction cost estimates.
Make sure to have a word with the building or civil contractors before starting the project, to avoid such circumstances.


In a volatile economy, it becomes extremely difficult to peg the prices of material, which affects the final cost of construction. If you are not in a hurry and is planning to construct your house at a slow pace, the variation in the prices shouldn’t be avoided.

If the construction continues for 2-3 years, the construction prices of materials, tools, labours, etc might get varied in the period.

Moreover, if you are planning to use foreign materials for construction, which needs to be imported, determining the prices can be difficult. It will either go up or down. In most cases, there is always an arbitrary rise in cost.

Consider these variations during the cost estimation process.


For a project that is not well understood by both the owner and contractor will lead to some unavoidable errors which affect the cost of construction Preparing a good quality plan with the proper specification can reduce the construction time to a large extent. Not only this, but it will also lead to better execution of the site.

If your planning is poorly done, it will not delay the project but can create confusion and doubt in the contractor’s mind which generally results in higher construction cost.


The last but not the least is operational efficiency. With higher efficiency, more amount of money is saved on a larger home compared to a small house, as in smaller house there’s less room for error.

A builder who solves designs problems on paper instead of relying on field personnel can end up saving money more than you can imagine.
The same applies to the building contractor who is careful in all orders and inventories, making sure that they’re accurate. You will get surprised by how much money is wasted with inaccurate material deliveries.

The builder who is efficient in his/her business can build your house within your budget while making better than average profit for the company.
