Building a grand design takes time and more often than not, takes longer than anyone expects. Phil and Ariana have given themselves just two weeks to build their home in Maianbar, in Sydney's south, regardless of the fact they've never built anything before. 

Utilising a build system that has never been used for domestic housing in Australia before, this could either be a new blueprint for construction in this country, or a complete disaster. They've chosen a building method popular in European residential construction - cross-laminated timber which is essentially a flat pack home using wood compressed to be as strong as steel. 

With the design focused entirely on making the water views the centrepiece of the build, the house is put together piece by piece like a giant Meccano set. But with 130-plus timber panels precision-cut in an Austrian factory and installed in a strict order on site, there is no room for error. With Phil drawing on his skills in HR to project manage, will his unrelenting obsession with a strict time frame compromise the integrity of the design?

Anglican Reverends Neil and Ruth have a shared love of all things Gothic and medieval. So when the couple decided to build their first-ever family home in the Adelaide suburb of Hillbank, it was no surprise that the city of churches would provide plenty of inspiration. Not that they want a church-like house. 

Neil is chasing a barn-inspired house with big, heavy timber beams. So they've chosen to create a medieval manor built in the traditional way using methods from another time. The bones of the house's eight huge A-frames will be built by hand out of timber by a team of specialist carpenters. Thousands of timber shingles will cover the massive roof, with a two-storey high Gothic glass window the centrepiece of the house. 

But Neil is constantly let down by suppliers and has grossly underestimated the cost of the build, so work on the site stalls. When summer hits and temperatures soar well into the 40s, the exposed A-frame timber beams begin to warp and crack. They elect to use something straight off a warehouse floor - insulated refrigerator panels on the roof and walls - a most unlikely fit for a medieval house. 

Not only do they look incongruous, they are hell to work with and expensive. What ensues is a tug of war between old and new materials; between a passion for the past and unsavoury reality. With a blind faith that sees Neil try to ignore spiralling costs, he enlists the help of his family to finish his passion project, turning a build he hoped would last a few months into a five-year revelation.
