Seven condominiums at The Residences at Oceania located at One Longbeach Ave. in Hull sold for $4.5 million at auction on May 9.

The sale was marketed and coordinated by real estate marketing firm Flynn/Boston Realty Advisors LLC.

Oceania is an upscale residential condominium building owned by Seven Hills LLC of Weymouth.

"This was a great opportunity to purchase an oceanfront residence," said Auctioneer Dan Flynn. "Since Oceania sits high on Atlantic Hill, every unit offers commanding views of the ocean and the Boston skyline. When you combine that with unique architectural features and the overall quality of materials and construction you begin to understand the demand."

The Residences at Oceania consists of 16 newly constructed units.

Winning bids ranged from $530,000 for a 2,882-square-foot unit to $875,000 for a 2,798-square-foot penthouse unit with its own roof deck.

These units previously listed for $1.23 million and $1.43 million respectively.

One unit was designated to sell absolute, subject to no minimum bid or reserve price. That 2,338 square foot unit sold for $580,000.
