National Building Organization
The National Building Organization (NBO) was established in 1954 as an attached office of the then Ministry of Works and Housing primarily to take up research in low-cost building designs, improvement of the building and housing conditions along with the socio-economic aspects. NBO also functions as the regional centre for housing for ESCAP. In the past, NBO has been taking up public supporting research works in building designs, building materials and other socio-economic aspects.

Publications have been brought out covering all these aspects and also housing statistics. Having regard to current requirements under the National Housing and Habitat Policy to strengthen the management information system and various other related socio-economic and statistical functions connected with housing and other activities and also to ensure more effective and systematic technology transfer at various levels involving large-scale dissemination, use and commercial application of low-cost and innovative technology, NBO has been restructured during the year 1992 to take up mainly the socio-economic, management information system and creation of data bank.

The functions related to building materials and designs have been taken out of the purview of the NBO and given to BMTPC, an autonomous body within the Ministry. In order to cope with the creation of a strong database on housing and urban development activities the computer facilities in NBO have been strengthened.
