Dual occupancy / Duplex designs are when two dwellings are built on a sub-divided single lot. Many Project Builders now have these dual house designs as standard in their range.
Townhouses are classified as 2 or more separated houses built on the same lot, with sub-division. Typically you will need to have plans drawn up by an Architect before approaching a builder for pricing.
If you have any questions or require pricing please enquire on our prices page and we will call you back.
