The Brisbane suburb of Kangaroo point, which is predicted to double in population, could allow developments up to 20 storeys high to be built under a new city plan.

The Brisbane city council have discussed the draft of the Kangaroo Point Peninsula Neighbourhood plan at a meeting on Tuesday which was sent to the state government for approval.

Residents had the opportunity to have their say, with the current neighbourhood plan allowing a maximum height of ten storeys potentially being doubled in some areas.
