More than 1350 homes are touted for a new $900 million suburb between Upper Kedron and The Gap.

The massive development is one of Brisbane’s largest proposed property developments, covering 227 hectares next to the D'Aguilar National Park, an area bigger than South Brisbane and West End combined.

A new $900m development is touted for The Gap.

However, Lord Mayor Graham Quirk said about 90 hectares of the bushland would be preserved.

“This will include a significant portion of land being handed back to the people of Brisbane for conservation and recreational purposes,” Cr Quirk said on Monday.
