Helping build urban houses faster, cheaper

The News:

  • Recently, the Center has launched Global Housing Technology Challenge (GHTC) among stakeholders, a move aimed at introducing best technologies that seek to construct houses in a shorter period of time with lower cost.
  • The Centre will offer about ₹150 crore as a technology innovation grant to build 6,000 homes in a cheaper, faster and better.


  • PMAY-U was launched in June 25, 2015, with a target of providing 1.2 crore houses by 2022.
  • However, only around 8 lakh houses have been constructed under PMAY-U which does not even account for 10 per cent of the revised ministry target.
  • Thus, to accelerate PMAY-U’s target of providing ‘housing for all, Global Housing Technology Challenge (GHTC) has been launched.

About Global Housing Technology Challenge (GHTC)

  • The Challenge is a part of the technology sub-mission of Pradhan Mantri Awas Yojana Urban (PMAY-U).
  • Aim: To accelerate PMAY-U’s target of providing ‘housing for all.
  • Focus: Identifying and mainstreaming proven demonstrable technologies for lighthouse projects and spotting potential future technologies for incubation and acceleration support through ASHA (Affordable Sustainable Housing Accelerators).
  • Four parameters: Time, Cost, Quality, and Sustainability.
  • The challenge will invite ideas from across the globe for alternative technologies that go beyond the brick-and-mortar building model used widely in Indian construction.
  • The winning technologies would be used to build mass houses, in a tie-up with the states under the affordable housing project vertical of PMAY-U.
  • Such houses will be constructed in varying geo-climatic zones across the country.
  • Finance: State and Central government will assist with ₹1.5 lakh each, also an additional technology innovation grant of ₹2.5 lakh for each house will be provided by Central government.
  • Issue: The use of innovative technologies will be optional for use, and there is no guarantee they will be adopted by private or government builders, or even used to construct PMAY homes. Thus, there is need of mindset change also.
