The first detailed plans for new units to be built on government-owned land along the Metro Northwest train line have been released.

Tallawong Station south in Rouse Hill will get about 1100 units in an area near The Ponds, with buildings up to 8 storeys tall. The plan includes parking for 1015 cars and 1210 bicycle spaces. One of the "key principles" of the development is to encourage greater use of cycling by residents.

A minimum of five per cent of the units will be used to provide affordable housing for at least 10 years.

The original 2013 North West Rail Link Corridor Strategy recommended that residential development close to the station should be three to six storeys but changes to planning rules permit greater density and buildings up to 26 metres tall.
