Overcoming its alarming reports on polluted Yamuna and unplanned housing layouts, Delhi has found a new reason to be cheerful. Delhi gets its first individual green home. The house is located in south Delhi’s Chittaranjan Park. The name of the house is ‘Green One’. The inspiration behind this home came from the ITC green building in Gurgaon. Prashant Roy the owner of this house decided to re-built his house at C.R park in an ecofriendly way. Some of the principle constituents used in recycled materials are, fly-ash bricks and (ACC) Autoclaved Aerated Concrete bricks. To reduce heat there is an overall fenestration. Few bricks were used from left over debris which were made from industrial waste materials compared to normal bricks which contains high amount of carbon. This five storey greenhouse costed around 4 crores.

This five storey building construction cost came within 4 crores. Roy says that, ‘the construction cost per sq. foot was 10 percent less than a normal building of the same dimensions’.
“My wife was really supportive through all the time and effort needed to get this project going. My daughter was six years old when we moved in and she was very excited, and read up about green buildings and spoke about them at school,” Roy said.
“People mistakenly believe a green building costs a lot more. The extra cost isn’t much, but you save money on electricity and water,” he said.
