Moreover, Ministry of Housing and Urban Affairs (‘MoHUA’) also considers ‘retirement homes’ as a separate category and has released ‘Model Guidelines for Development and Regulation of Retirement Homes’. Furthermore, within the larger category of retirement homes, provision of services for development and sale of standalone houses, villas etc. is a distinct product compared to services for development and sale of residential flats/ apartments. While standalone houses, villas etc. allow buyers to decide on their own discretion the floor plan, structure and other specifics of dwelling units subject to applicable regulations, no such discretion is available to a buyer of a residential flat. Hence, residential flat forms a separate relevant product market within the category of retirement homes. Accordingly, the relevant product market in the instant case is delineated as the ‘market for provision of services of development and sale of retirement homes in the form of residential flats’ .
