The suburban revolt against the NSW government’s medium density code is gathering pace, with four councils granted a 12-month delay of the new rules that make it easier for homeowners to build terraces on their properties.

Another five councils are seeking a deferral of the new planning rules to consider the impact of increased density.

Ryde, Canterbury Bankstown, Lane Cove and Northern Beaches councils have been granted a deferral of the code until July 2019.

A spokesman for the Planning Department, meanwhile, has blamed councils for failing to prepare for the new rules.
