Marinas Internationale Ltd., designers and builders of marinas, has moved its headquarters from McLean to a 6,000-square-foot facility in the new Sugarland Business Park in Herndon.

According to the company's president, Keith Larson, the move to the new building at 380 Herndon Pkwy. will let the firm consolidate administrative and engineering divisions, formerly located in separate buildings, and will double its available work space.

Since 1967, Marinas Internationale and its predecessor, Buethe Marina Systems, have designed and built 175 small-boat marinas and yacht harbors on five continents. Larson said the firm is currently working on projects in Texas, Louisiana, Florida, North Carolina, New York City and Boston as well as on a $3.5 million marina in Kuwait.
