Archicentre cost guide: find out the real cost of your renovation

 

Market summary:

Established home sales continue to remain strong following a period of great activity and Archicentre has seen increased interest in both renovations and new home design concepts. Price changes have been negligible since the last Cost Guide, but continued growth in other areas may fuel material and labour price rises into the future.
