Brett and Rees are the proud parents of three young boys and desperately need more space. They love their inner-west community in Sydney's Annandale, so the plan is to build on the small empty allotment behind their apartment.

Exhausted by ongoing battles and a build that's months behind schedule, will Brett and Rees have enough grit and determination to see their project through to completion?
