The NSW Planning Minister, Anthony Roberts, will consider suspending a new code that makes it easier to build medium-density housing for any council that wants to change its planning rules.

The offer follows almost three years of promoting the concept of more "missing middle" terrace-style housing, and comes a month after the promised introduction of the code, exposing the government to claims of another backflip.

Mr Roberts this week suspended the so-called medium-density housing code in the City of Ryde and the City of Canterbury Bankstown – after both councils argued it would allow densification in areas ill-suited to more housing.

On Thursday, Mr Roberts said he was "prepared to extend" this offer to any other council in greater Sydney seeking a fix to its local environment plan, or planning framework.
