Though the Island's first rotating house is still a year away from completion, the owners have had so much interest they've decided to hold an open house for charity this weekend.

Steve and Stephanie Arnold are building the house with a 360–degree ocean view in North Rustico. For a $5 donation, visitors can tour the two–storey, 5,000–square-foot rotating home on Saturday.

"We're hoping to give everyone a tour because everyone seems to be quite interested in how the house rotates and, at the same time, we thought it would be a good opportunity to raise some money toward the North Rustico fire department for the rescue truck they're trying to get," Stephanie told CBC News.

The house completes a rotation once every 45 minutes, then changes direction and turns the other way.

Plumbing and wiring run up the central axis of the house, and flex and pivot as needed. Steve says the exterior walls and roof are made from hurricane-proof pre-fabricated components from North Carolina.

"Well it's a Del–Tech Home. They've been building houses out of North Carolina for 40 years and they are some of the most well built homes in the world. They've withstood Hurricane Katrina," Steve said.

The upper floor will be the couple's summer home when construction is completed next year. The plan is to run the main floor as a bed and breakfast.

The open house on Lantern Hill Drive runs Saturday, 12 p.m. to 4 p.m.
