Most people think Ipswich architect Graham Birchall is joking when he tells them he lives in a bubble house.
"Sometimes people don't believe it when I tell them where I live," he said.
Mr Birchall said the design was something that had to be seen to be believed.
"There are 11 domes in all ranging from four metres in diameter to eight metres in diameter, it has 16 rooms over three levels so it's rather large," he said.
"It's got two libraries, a movie theatre, and circular windows that open and close with an iris.
"I love it because it is so spacious. You don't even notice the ceiling and the spaces just flow on from one to the other."
The Ipswich architect built what is known as 'the bubble house' in Karalee, west of Brisbane, in the 1980s after an idea he had during his final university thesis.
Mr Birchall researched ferrocement — a mixture of iron and cement not usually used for homes — as part of his architecture degree.
"I thought, let's see if it works and we designed the house," he said.
"It took 10 years to build, we built on weekends from Father's Day 1983 to Father's Day 1993.
"There were a lot of challenges — we had to invent a lot of tools like a curved ladder to build it.
"We calculated it all manually as well, one dome took six pages of manual math calculation to work out.
"It was a lot of fun to do."
"Half of it is the Flintstones and the other half looks more like the Jetsons."
Mr Birchall even contacted NASA for some tips on design and said they responded and offered some tips.
"I knew they had something like it on their mars rover and they sent the drawings to me, I was surprised they answered the phone call," he said.
Mr Birchall said it made the tough choice to put his property on the market on Monday after decades of living and working from his dream home, but said he was excited to move closer to his grandchildren.
The architect said he was already planning to design a new, equally unusual home.
"It won't be exactly like this but it won't be typical," he said
"I don't have too many straight rulers, but you have to have a bit of fun when you're designing.
Real Estate agent Helene Shephard said hundreds of people had already contacted her about the listing.
"We've had locals but also people from interstate and overseas, we've had calls from Vanuatu and as far as France."
