The owners of a home on Mt. Helix said they are in the sixth year of a 10-year plan to build their dream home.

It is a home unlike any house you have seen before.

Why is this house unique?

It is round -- unusual, but not unique.

It has a great view -- nice, but hardly unusual.

What is really unique about this particular home is that the house rotates.

This special home rotates 360 degrees.

Al and Janet Johnstone came up with the idea six years ago and did most of the work themselves.

Al Johnstone learned by doing.

He is a retired personnel director, but in this case, he was the architect, engineer and contractor.

Everyone asks a lot of things about this house.

For instance, many have asked about having plumbing and electricity in a rotating home.

Al Johnstone patented a system where pipes and wires rotate with the house.

“I turned the plans in and the county was gracious enough to grant us a permit,” said Mr. Johnstone.

During the building process, there was never a point where the Johnstones asked, “Are we crazy?”

“No. I have loved it all the way. It’s been a lot of work, but we love it," said Janet Johnstone.

"She has been a jewel,” said Al Johnstone.

The Johnstones wanted a nice view from any room in the house.

The master bedroom initially has a view of the driveway, but wait a few minutes and the master bedroom has a great view of the El Cajon Valley.

“Just to be out here and watch the world go by and you’re just sitting in your chair -- it’s beautiful,” said Mrs. Johnstone.

They can watch the light change and the weather change.

On the Fourth of July, the Johnstones can see 18 different shows, thanks to their house.

The house can rotate completely in as little as 30 minutes.

There are variable rotating speeds and it rotates in either direction.

The home does not rotate fast enough to make a person dizzy, or for centrifugal force to throw you into the walls.

The house is also pretty high-tech.

There is a computer that controls the lights.

If you want to change the lighting, you can use your voice.

“You just talk to the house and it turns on the lights,” said Al Johnstone.

People ask the Johnstones what happens if they lose power.

If power is lost, the house does not rotate.

Most of the time, though, it does. After all, the world does turn -- why not a house?

The Johnstones will be hosting tours of their home the next two weekends starting Friday.

The tour will be part of a benefit for Foothills United Methodist Church and Habitat For Humanity.
