Twenty-eight wheels, two motors and the power usage of a light bulb - that's all it will take to move Canberra's first rotating home.

Dubbed Girasole, meaning follow the sun, the house will be able to complete a full rotation in less than 10 minutes once completed early next year.

Currently under construction in the northern Canberra suburb of Crace, the four-bedroom home designed by DNA Architects and Industrious Design will allow residents to take full advantage of natural light and solar efficiency by rotating the house using a touch-screen panel.

Builder and owner of MAG Constructions, John Andriolo, said the house would also be able to track the sun automatically.

''Girasole will encourage a change in thinking away from needing to find perfectly oriented blocks and will demonstrate that even the most ambitious undertakings can be seen as a prototype for future environmentally friendly homes,'' he said.

Mr Andriolo said the eco-friendly single-storey home also included a sloping roof hosting 10,500 kilowatt solar panels able to generate enough energy to power the home and its hot water system.

Peter McKay, from Industrious Design, said the design work took several months. He said there were a number of safety elements involved in the design, which has no overhang and features fixed components such as the walkway and verandah.

''It's only the home itself that rotates,'' he said.

Mr McKay said the rotation also used minimal energy, due to the lack of lifting involved in the process.

''We think it's about 100 watts, which is about the same as a bright light bulb,'' he said.

Mr McKay said although rotating homes were likely to remain a niche market, the eco-friendly design could inspire other projects.

''It's never going to be the main type of houses people design, but it has its benefits,'' he said. ''You may see more of these homes out there.''

Ross Norwood, from DNA Architects, said there were two or three rotating homes in Australia, but all were different and noisier than the Canberra model.

Despite the unique design, Mr Norwood said the planning process for Girasole was relatively normal.

The design did raise some initial concerns regarding privacy but he noted that the home faced either the street or the backyard for the majority of the year.

The home, on a 704-square metre block, with a large underground water tank, is expected to be finished by February.

I do see potential.
Couple of questions.
I see a wheel (presumaby the house will be on it) and a house in construction in the background. Are they building it off the wheel then putting it on the wheel, or is that the neighbors house and they will construct a new house on the wheel?

How does one hook-up to water/sewer/electric with the rotation? Electric here is overhead (and as Sandy has shown, that type of hook-up really sucks), but water and sewer hookups are underground. Do they use flexible pipe and don't rotate past a certain degree where they then rotate the other way?

100W to turn a house, in the time they say they can? I would like to see the motor, it's amperage and the tonnage the house is. Also, is that the power they will take from the grid in addition to whatever solar power they are getting? I use more than 100W to filter my pool. I don't believe the math.

What kind of maintenance does it require? I would guess a twice yearly greasing of bearings in the wheels and other such things. Also, if there were an earthquake and/or hurricane, is it rated for those things? Shock absorbers, tie downs etc.

Brilliant questions, but sorry I have no answer for them! :D

This one, at least, has an answer: comparing the house in the photo with the "artist's impression of the completed house," it's pretty obvious that the house in the photo must be the house next door. (There also appears to be another house under construction further in the distance.)

Central hookups with specialzed fittings. Though being Solar Electric wouldn't be an issue ;)

I guess that would work. For a while. Maintenance will need to be done periodically. Anything moving, always needs maintenance. Heck, things standing still need maintenance, just not as much.
Never thought I would have to "lube" my house.

So the electrical engineer is ignoring the solar bit eh? ;)

THere are alot of fittings that last really well. While specialized such fittings are nothing new technologicaly.

Not ignoring the solar, I just agreed with solar there is no need for hooking up to the grid, as long as they have the battery backup for night time.

Plumbing and sewage were my focus. And I still would like to see where a 100W motor will rotate the house.

I am open to all new technology/inventions/techniques, I would just like to see the details.

I don't believe the numbers one bit -- and that's based on looking at efficiency numbers for wind energy lately -- but I'm no engineer.

I do like the idea, in theory. I could have heated most of my house yesterday from the warmth of the sun coming through my unheated sunporch windows in the afternoon. In fact -- I did heat the downstairs pretty much all afternoon that way!

Solar will heat/cool/power an average house during the sunlight hours very effectively. After sunlight hours, not so much (if at all, aka night time). Either battery backup (very expensive) or grid hookup are needed. And I still go back to 100W to move a house and water/sewer hookup.

I am sure better minds than mine have figured out the solution, I would like to see those solutions. In the limited amount of knowledge that I have on construction and matters that relate, my house would go 360 degrees then have to backtrack that same 360 so as not to wrap up the "hoses" for water. Sewage would be down the center with a rotating collar as there is no pressure in a sewage pipe.

actually they say there are two motors. thad that they "think" it's about 100w.

Not a new idea at all. Not even the name is new. (I noticed that this earlier one used 2 diesel motors totaling 3 horsepower, which is considerably more than 100 watts (over 20X more)--but it WAS built in 1935, after all...)
