This web site is about our low-cost home built mostly using reused construction material and a bunch of ‘reduce’ ideas, and rules that our family uses to live a (relatively) low-carbon life.

Our home was featured in the home interiors magazine, Livingetc. Click here to see the article.

A low-carbon roof over your head
Our house is low-carbon, looks stunning, has lots of ‘Reuse’ and ‘Reduce’ , and is cheap. It cost 50 % of what a regular house would have cost to build. See ‘Our kachra house’ for :
– Ideas that we used.
– Sources for designs and reused building material.

Reducing energy consumption in your day-to-day life
We can reduce our carbon footprint through simple and small changes in our daily activities. See ‘Living an earth-friendly life’ for :
– Things you can do to reduce your energy consumption.
– Things that you can do to reduce using chemicals harmful to the environment.

A quickie guide to ‘carbon footprint’ and other jargon
See ‘What the hell is low-carbon?’ for :
– Explanations on common terms.
– Some basic calculations to determine your carbon footprint

If you have any new ideas
You are welcome to add them as replies. I’ll pick out the good ones and add them to my list.

    Hello Sir,

    Its an very good attempt to share low carbon ideas through blogging. Even I am following Sustainable life styles, as an attempt towards Greener planet.
    And following video shows us one idea of procuring natural Drinking water(would be much better than mineral water)

    I am from Pavagada so I know the advantage of this method.

      Saw the video. That makes sense, and I’ve been thinking of putting in a charcoal filer in my home’s rain water system too.

    Hi, we really like your ideas and your house. We are staying in Delhi – do you have any idea of similar projects/like-minded people in Delhi who could advise on where to find second hand stuff? Thank you! Anna & Narendra

    • July 7, 2013 at 12:10 pm

      I can ask around and see if any Delhi-wallahs here know about sources.

    Hi I’m dhruva
    I just thought of a great idea I think mite help in reducing carbon footprint
    the most worrying problem in Bangalore is its ever-growing traffic and pollution
    I think cycles are a great way to reduce traffic and GHG emissions
    but the main reason not every one cycles to work, schools etc. is that they think they cant cycle that much(though most can)
    also cycles cant be used for very long distances

    why not put a electric induction motor on the rear of the bike, which acts as a driving motor and a electric generator

    the electric energy is produced when the person pedals.
    the wheels rotate which is connected to a gear
    the gear drives a chain which rotates the motor
    the motor produces electricity which is saved in a battery
    the pressing a switch, the battery starts to give out electricity
    the motor starts turning and the chains drive the wheel
    and the cycle goes ahead without having to pedal
    when the battery gets discharged, the person would have to pedal again which will charge the battery and this can go on and on

    this will give no emissions, and cost efficient as no fuel is used
    it might just give u a bigger appetite(LOL)

    only problem is that I don’t have resources
    im only 14 after all !!!!!

      Dhruva, thanks for the post. That’s a nice idea. The battery could be even charged when you apply the brakes – it’s called a regenerativce braking system. I’ve actually been seeing a few electric bicycles around, but I think they’re Chinese made. You could actually write to some Indian bicycle manufacturers like TI cycles and Hero, sugggest this. And don’t let the fact that you’re hold you back. A person with sense will listen to a good idea irrespective of who it comes from.

    HI Mr Das

    This is fantastic, very creative. Since I am embarking on constructing a house myself, meeting you will help me greatly. Could I meet you in person and also get a firsthand tour of your house, it would help me immensely.

    Thank You

    Helloo sir i want to build a house in uttarakhand

  18. March 22, 2018 at 2:35 pm

    Been looking for ideas to build a sustainable home, in a place, that chose us! Yours is like a dream come true for me! I am quite nutty too and my sojourns into the dark deep alleys of chor bazaar in Mumbai or in Ahmedabad have my folks smirk at me..nevertheless. Kudos to your vision and actioning it! Will love to get in touch for my own sustainable dream house with a square foot garden around, as I am a home gardener, all my food comes from what I grow. Farm to kitchen and viceversa. Thank you for treading lightly on this Planet!!

    • March 22, 2018 at 5:50 pm

      Hello Lima.
      Thanks for the nice words. I’ll email you my contact details.
      Will be glad to help with any ideas, and would love to get some gyan on the kitchen garden from you once I start one.

    Hello sir,

    I am Pratiksha, an amateur architect in bangalore.I went through the blog and found it very interesting. I am not sure if I missed portions of the blog that spoke of what the walls are made up of. I only understood that the house was built on an already existing foundation. May I know what the walls are made up of and if they are also environment-friendly?

    Thanks in advance,
    Pratiksha
