We are planning to construct the house with parking for one small car along with 1BHK at Ground Level and from First Floor onward’s 2BHK with dining area and balcony. I would like to know what materials like Cement, Bricks, Iron etc. should I use for the construction of my house in terms of durability, strength and heat resistance quality etc. etc.

    In overall, I am a layman so I would like to know each and everything about the construction of a house, as you can understand that construction of a house is done only once in a lifetime for a middle class person like me.

    Would be much appreciate your valuable suggestion and comments to go ahead with my planning of building a house and will be much obliged for the same.

    Thanks & looking forward to a positive response to my request.

    Best regards
    Anu Mohandas

  2. Superb article that states the very essence of firm foundation! Being a civil engineer, after years, I finally made my own house in my hometown a year ago. I used fly ash bricks along with Roff Supercrete as mortar and only not even a single crack has developed over the period of time, despite heavy temperature variations. Bricks do play the most important role and so does soil density calculation which ensures your foundation is perfectly laid and the soil is well set. Hence, one has to take care of all the factors including proper mortaring.

  3. Very interesting article, I am right now in the process of constructing a house and brick work will commence in a few weeks time. I am looking for alternate means for reducing the house construction cost especially replacing traditionally used burnt clay bricks with other materials such as GFRG panels, fly ask bricks etc. Could you please help me in deciding the material which I need to use for construction and also regarding dealer contacts or approx pricing of fly ash bricks .I am constructing house in trivandrum.

  4. very useful article KINDLY TELL WHERE WE CAN GET RATES OF SUCH BRICKS IF U CAN PROVIDE RATE COMPARISION IN YOUR ARTICLE ITSELF IT WOULD BE GOOD FOR LAY MAN LIKE ME…………..

  5. For working with Fly Ash bricks, masons does not need any special skills. Its just as easy to use as Clay bricks are used.

    Since now a days, availability of clay is becoming hard and hence, the cost of Clay bricks are rising. Therefore, Fly Ash bricks can also be used for cost effective construction. However, you have to compare yourself the cost of both bricks in your region.

    We are sorry to say that we don’t have any information regarding the availability of Fly Ash bricks in Bangalore. Therefore, we would suggest you to either conduct a survey in your region or you may also search in the internet for the same.

  6. Dear Sir/Madam,

    Please clarify on these points.
