    The cost to constructing a 30×40 Duplex house in Bangalore of G+1/G+2/G+3 Floors may range between 45 lakhs for a Standard construction and upwards of Rs 1crore+ for a luxury house.

    Several factors affect the actual cost of construction while building a house; some of them are mentioned below:

    • Location of the site: If the required construction materials or raw materials for house construction are located far from the construction site, the transportation cost may be added to the final cost.
      .
    • Types of building or construction materials used: During the house construction process, the price of the material differs depending on the type of construction materials you choose to construct your house.
      .
      You can buy standard to premium quality building material as per your need. Also, eco-friendly materials could cost extra as they need additional preparation and skilled labor to construct.
      .
    • Skilled labor charges affect the construction cost: Highly skilled labour would ask for a good paycheck, whereas inexperienced local workers may work at the lowest wages. Both will have some pros and cons attached to them, which the owners have to deal with and choose wisely as this might reduce or increase the construction cost of your Duplex house.
      .
    • Duplex house construction is entirely different from rental house construction. A Duplex house requires more high-end finishes when compared to a standard rental house.
      .
    • Architects fees would significantly affect the final cost as most professional Architects charge high prices ranging from 3 to 5% on the project cost to design the duplex house due to its complexity in construction.An Architect needs to give more time to prepare detailed working drawings, and you need to make sure that you hire an Architect or Architectural firm that meets your requirements and charges within 3% on the construction cost.
      .
    • The interior of the 30×40 Duplex house is done according to the client’s requirements. The more lavish the interior, the more costly the construction is. Finally, the finishing material gets added on top of the construction cost.
      .

    So consider all of these factors when you decide to set a budget for house construction for a 30×40 duplex house in Bangalore.

    If you plan to build just a 3BHK Duplex house in Bangalore of G+1 Floor, I would suggest you go for a 3BHK which would be a more spacious house when compared to a  4bhk.

    The cost for building a Duplex house on a 30×40 site of G+1 Floor with a built up area of 1800 will cost Rs 40 to 45 lakhs.

    As per BBMP by laws, you can get a FAR of 1.75 for a 30×40 site, which means 1200 sq ft (30×40) Site dimension x 1.75 FAR = 2100 sq ft.

    Besides the construction cost, one needs to keep aside 15 to 20%  additional cost for getting Borewell, Plan sanction for authorities like BBMP BDA BMRDA, Power connection from BESCOM, Architect fees, Water connection from BWSSB, Road cutting charges etc.

    It’s estimated that the 30×40 duplex construction cost in Bangalore varies around Rs 1700 / sq ft for standard finishes and upwards of 2300 per Sq Ft. If you have budget concerns, it’s advisable that you only hire a labor contractor to build the house and arrange the required building and construction materials from your end.

    This will reduce the construction cost significantly (10 to 15%) as you bypass the contractor’s profits from the final price.

    Note: Handling labour contractors is not easy, especially if you are a working professional. As one needs to move around to arrange construction materials and monitor the site regularly.

    Hire a good building contractor for your house construction. An experienced building contractor will help you complete your house construction within the specified budget and maintain good construction quality.

    The construction cost of a 30×40 duplex house in Bangalore may cost around Rs 1750 /sq ft and upwards of 2000/sq ft for a premium finish. Most of the construction cost goes into the material. Find the wholesaler in the other regions where the price of the construction material is less than what you get into a local store.

    You will see a significant difference in the material cost when brought from the other region. Get all the material to deliver in advance, so there will be no halt in the process. With this plan, you will be able to reduce the cost of construction to a great extent.

    The current 30×40 Duplex house construction in Bangalore will cost around Rs 1900/sq ft onwards; this cost might increase depending on the finishing materials used for Flooring, Cladding, Bath ware fittings, etc.

    In many cases, the contractor works with few experience and inexperienced workers to reduce the construction cost. Remember that the construction cost could go up if you hire only professionals for the job. Also, you should be prepared for unexpected events that may increase the final price.
