Adding to the home you already have, rather than building a second one. An extra bedroom, a second living area, a bigger kitchen, a main bedroom with an ensuite.

An extension pays no Lease Variation Charge. It adds floor area but not a dwelling, so there is nothing to vary in your Crown lease. A second dwelling on the same block can be $49,000 a home before you build anything — work out the charge on your block.

The first of our extension designs is below, with a walkthrough video of the finished build. We have drawn more than four hundred and the rest are being prepared for this website now.

Not quite it? Call 1300 979 658 or describe the room you need and we will send the designs closest to it. Or see Secondary Residences · Studios under 40m² · Homes above 90m²

About the prices

The build price of each design, rounded to the nearest dollar, including GST. What it could cost per week is worked out on each design’s own page.

Every design here has been drawn for a real Canberra block and priced. The price on each card is the build price and includes GST; planning fees and utility connections depend on your block and are shown on the design page. Floor area is the floored, enclosed space.

Finding a design you like is not the same as knowing it fits. Whether it is permitted on your block, and where it would sit, is a separate look at the block itself — Check My Block.
