Architect Peter Maddison returns for his 7th series on Grand Designs Australia.After a short break in 2016 the newest and biggest season of Grand Designs Australia returned to Lifestyle in 2017, with the first 9 episodes launched in April. Now we are kicking off 2018 with a bang with Season 7 part b – the 5 remaining Grand Designs that took a little extra time to achieve their out-of-this-world ideas. These 5 remaining episodes include a giant greenhouse enclosing a house, garden, stables and animal pens; a large spotted gum clad house built on an island amongst the koalas - that requires all material arrive via barge; a tech dream home with a two storey helical glass staircase; and last not be least, a heritage listed windmill.The leading Australian architect joins our homeowners throughout the process of turning ideas into reality, as people use design and architectural ingenuity to create an environment that best reflects their personality and ideals.
