Grand Designs Transformations

Blackburn. With two transformations on one site, builder Dylan tries to retrofit a cottage into a sustainable home while architect Tylah's plans for a garden oasis are battered with financial constraints.

St Kilda and Blackwall Tiny. A Melbourne couple turn a drab duplex into a spacious Miami-inspired home, while a NSW couple on a shoe-string budget create a tiny guest pavilion.

Belmont and Oatlands. In Geelong Victoria, Luke and Bree restore a Victorian cottage and add on a massive contemporary extension, while in the historic Tasmanian village of Oatlands, Karen and Stu restore a sandstone Georgian cottage.

South Yarra and Flemington. A little Melbourne workers' cottage gets a radical reimagining as a Mid Century Palm Springs oasis, while across town, a backyard shed is transformed into a Japanese bathhouse.

Glenbrook and North Balgowlah. A dilapidated 1960's duplex in the Blue Mountains gets a Moroccan makeover, while in Sydney can a giant boulder the size of a backyard be transformed into a rock top, poolside paradise?

Mornington Peninsula and Exley. An overgrown sloping bush block is transformed into a family retreat designed to embrace its natural surrounds.

Avalon and Balwyn. In two transformations, a couple turn a house on Sydney's northern beaches into a stylish pad and, in Melbourne, a family creates a flamboyant forever bathroom.

Henley Beach and Gold Coast. In Adelaide's Henley Beach, Paul and Marie transform an electricity converter station into a high-end entertainer's home, while on the Gold Coast, Chris and Antoinette reimagine a run-down house into a coastal retreat.
