Watch Grand Designs Australia Season 4 in Australia

After eight years of planning, Melbourne couple Glenn and Kate Morris are finally making a start on their striking, sustainable ‘sand dune’ house near Inverloch on Victoria’s Gippsland coastline. For them, this crescent shaped, spaceship-like design is the ultimate response to a wind swept location. Once building gets underway, the couple need even more patience as attention to detail is paramount in this curvaceous new building. Lets hope it lives up to their high expectations.

Greg, a former bricklayer is passionate about two things – his family (partner Emma & their 4 yr old son Archie), and...bricks. As a testament to his love for both, he’s building (literally with his own hands) a tri-level, solid brick contemporary terrace house with a cantilevered pool on the top floor. He’s creating it from the rubble of their well loved old house located on a narrow corner block in Sth Melbourne – all that will remain of the original building is its classic Victorian facade. Greg has dreamt of building this home for years and is certain the time is right, even though it means sharing the place with the in-laws.

Hoteliers Richard and Denise have knocked down the family home in the Adelaide Hills and are re-building an even bigger version, despite the fact their kids are grown. This modern mansion will have all the bells and whistles, amid resort like luxury on 3 tiered acres overlooking Adelaide. But is this unpretentious, likeable couple creating a home or a hotel for themselves? Money may be no object but have they taken on too much?

Ardent collectors Kerry and Judy have a passion for Sante-fe style, mud houses even though they live on a sloping bush block on Sydney’s north shore. Inspired by an unconventional builder who changes his mind (and their design) on a regular basis, they set out to create a home out of recycled timber and corrugated iron, rendered in clay dug up from the side of the road. It may be straight out of the American mid west but this hybrid home will have a distinctly Australian flavour and provide an earthy backdrop for their many artistic objects, artifacts and collectables.

Darren and Ruth Rogers have almost polar opposite views about what their new house should be. Darren wants all the bells and whistles – home cinema, wine cellar, even a lift. Ruth wants chickens, a vegetable garden and a hills hoist. Finding a design that will satisfy both of them and their young son Raymond, is their shared aim.

Chris and wife Belinda bought the small ‘car park’ of land next door to their existing house, just 3.9 metres wide: literally a tiny gap in a long row of heritage listed cottages in Sydney’s inner west Forest Lodge. Their plan is to squeeze every centimeter of land into a uniquely sustainable house.

Thirteen years ago Meredith and Matt Bayfield needed an escape from their busy lives as doctors in Sydney so they purchased a working sheep property at Ilford in the central table lands of NSW.

Daniela Turrin, Niran Peiris and their son Calum are doing something no-one in their historic street in the prestigious Sydney suburb of Hunters Hill has done before. They’re knocking down their old house to build a smaller one. But these are people who believe that the family that spends time together stays together – a premise that forms the core of the design of their new home.

Anchored in the middle of Bass Strait and subject to ferocious winds, King Island is about as far from the tropics as you can get in Australia. Artists Di and Andrew have decided to build a house there.

Budgeters Cole and Jane have bought a thin sliver of land in the hilly suburb of Dynnyrne, in Hobart, with the hope of building an eco-friendly home.
