Mixed commercial and residential developments are areas used or intended mainly for both residential and commercial uses. Unlike a pure commercial development, they can have a maximum of 40% of the total allowable gross floor area allocated to commercial activities, ensuring the residential component remains dominant. Typically, the commercial portion cannot be located above residential units. A common building form would be a shopping or office podium with an apartment tower block above. Strata subdivision may be allowed, subject to guidelines and street block plans governing the site.
