Under Armour is looking to double the size of its Baltimore headquarters to accommodate additional employees, as well as a 20,000 square-foot retail store, athletic fields and a company museum. Underground and surface parking are also planned.

UA is looking to add another 400,000 square feet at Tide Point, an office complex in the Locust Point neighborhood of Baltimore that the company acquired earlier this year. It had rented the space for the years.

The company's plans were first reported by the Baltimore Business Journal, which noted that the Locust Point community is concerned about the speed at which Under Armour hopes to move. Residents at a meeting held Wednesday night also expressed concerns about potential traffic and the size of a planned 20,000 square foot retail store.

J. Scott
Plank, Under Armour’s executive vice president of business development,
revealed plans to Locust Point residents Wednesday.

He told the Baltimore Sun that Under Armour employs nearly 5,000 people worldwide, up from 3,000 at the end of 2009. About 1,200 employees will work at the headquarters complex by the end of the year.

He said the planned museum would help people understand the firm's culture and milestone moments, from the first T-shirt to the first ad.
