Since its inception in 1974, Greha has concentrated on the growth of knowledge in the field of environmental development, habitat design and architecture. The thrust of Greha's efforts have been towards addressing issues of the majority of the population; the focus was the marginalised people in rural and urban settlements; the vehicle was developing knowledge and methodologies concerning settlement systems more suited to our history and cultural context.

The founder members, during the early stages of their professional careers, would meet periodically to engage with majority concerns, away from the routine of the practice.

These concerns led them towards working with the poor and marginalised people in our society and eventually to the establishment of a school of habitat studies.

Greha registered in 1986 as a non-government, not for profit society, with the aim of generating a body of ideas, involving diverse professional talent and promoting expert contribution in development projects undertaken by public agencies.
