Two Melbourne couples transform their homes - one will be monochrome, the other exploding with colour. Both battle setbacks and doubts as they chase wildly different visions.

In Brisbane, a classic Queenslander merges with a modern home. Meanwhile in Dubbo, a rundown church becomes a rejuvenated wedding chapel.

In Adelaide, professionals Hamish and his wife Gabrielle plan to return their beloved 19th-century house to its former glory. In the Melbourne suburb of Coburg, couple Georgia and Mete have two bathrooms that need transforming.

In Brisbane, husband and wife Oz and Kristy, set out to create a Turkish-inspired Queenslander. In Victoria, single dad Greg scrapes together a few thousand dollars to reimagine an Aussie shed into a Zen Japanese bathhouse.

In Adelaide, Cat wants to turn her 19th-century bluestone villa into a showcase for multi-generational living, and on the NSW Central Coast, Joe and Katherine want to transform their garden shed into a multi-purpose studio.

In Melbourne's Balaclava, Paul and Isobel want to add structure to the emptiness of their old hat factory, and in Sydney, Ian wants to tranform his iconic terrace into a Japanese inspired haven.

Sydney builder Buddy has a thriving company, but it's keeping him from building his wife's dream home. Carpenter Brian and wife Danielle transform a dilapidated Toukley shed into the first home for a much-loved aunt.

In Mulgrave, Luis and Laura plan to convert their cosy Spanish mission home into a mid-century Japanese haven, and in Tasmania, Richard and Alice have their hearts set on saving a 140-year-old crumbling glasshouse.
