Architect Chris Moller meets Southland farmer Lachlan McDonald, who's building a modernist concrete home with a controversial roof in one of the most remote parts of NZ.

Chris meets Gus and Sarah whose solution to spiraling house prices is to make their first home an Earthship - an off-the-grid house made of recycled rubbish, earthen bricks and clay. An Earthship is a non-traditional home built using recycled materials such as bottles and tyres, and even mussel shells for insulation. Young Coromandel couple Gus and Sarah Anning decided to step outside the norm with their Grand Design when they realized they couldn't afford a traditional home. Enlisting the help of community volunteers, both here and overseas and using unique building techniques originally designed for the desert in California, it's not certain how this Grand Design will fare in Coromandel's temperamental climate.

Chris meets Scottish migrant and urbanite, Scott Lawrie, who has a dream for a new life and a radical new stainless steel home in the remote hills behind Pakiri. Sydney-based writer Scott Lawrie's plans for his new life in New Zealand are encapsulated in a sculptural steel house he is building on a remote rural hillside behind Pakiri beach. Scott has an unrelenting refusal to compromise on his "legacy", but a budget can only be stretched so far. Will Scott realize his extraordinary dream?

Chris meets builder Steve Sygrove, who's planning to build and ornate and colourful American Gothic home in the Titirangi bush. Fifth generation builder Steve Sygrove and his wife, Chrissy, have a passion for things pretty, floral and pink. Their unique build in the Titirangi bush near Auckland is a handcrafted American Gothic style house complete with ornate detailing like a Juliette balcony, spandrels, a horseshow window, lacework valences, and interior walls made of fabric. Steve rallies against the bureaucracy that is stifling the creativity in his craft and expects this grand dame of a building will be his swansong.

Chris meets architect Nic Ballara, who's planning to build a house on a steep 45-degree slope overlooking Wellington. Nic Ballara clearly has a head for heights as he starts to build a family home for him and his wife Callie and their 12-year-old daughter. Nic's site in the earthquake prone city of Wellington is so steep that it looks virtually impossible to build on, however Nic is convinced he has a solution and is determined to build his first home there. A logistical nightmare lies ahead as this Grand Design looks to be an uphill battle throughout.
