The committee on Standardization of Doors and Window sizes for Residential Buildings consisting of experts from CPWD, Confederation of Construction Products and Services (CCPS) and IBC (Indian Building Congress) submitted a report to the MoUD for acceptance. The MoUD has accepted the report and advised that these sizes be adopted by CPWD and adequately publicised among the major construction agencies and the industry, for their adoption.

CPWD has standardised the sizes of door and window in government residential buildings and for dissemination of this information, the organisation is bringing out a manual. Standardisation of fittings and fixtures should not only lead to qualitative improvement of the buildings, but also reduce the cost of construction due to economies of scale in production of these items.
