Appliance maker SharkNinja has completed its move into a new build-to-suit headquarters in Needham as part of the reinvention of one of the nation’s oldest office parks.

SharkNinja consolidated workspaces for its 400 corporate employees into a new 175,000-square-foot building designed by architects Sasaki at 89 A St. within Normandy Real Estate Partners’ transforming Founders Park.

The open floor plan designs are intended to foster collaboration between members of various departments including product development, marketing, engineering and sales, SharkNinja said.

“We’re finally in an all-inclusive space that feels authentic to SharkNinja’s identity and spirit, while further enhancing our ability to deliver products that delight our consumers,” SharkNinja President Mark Barrocas said in a statement.

The company markets vacuums, steam mops and kitchen appliances under the Shark and Ninja brands.

Normandy Real Estate Partners acquired the former Needham Crossing Business Park in 2014 for $54.5 million and built a new 281,000-square-foot headquarters for TripAdvisor, which relocated from Newton. Normandy also obtained approvals to add a hotel, 390-unit apartment complex and redevelop buildings formerly occupied by General Dynamics Mission Systems, which relocated to Dedham. In May, Needham voters approved a tax increment financing agreement for NBC/Universal’s future 165,000-square-foot headquarters, to be built at a former General Dynamics site on B Street.

The mixed-use repositioning of the property is billed as an early success story for the N2 Innovation District, which promotes economic development in a nearly 500-acre area near Route 128 in Needham and Newton.

SharkNinja’s former offices at 180 Wells Ave. in Newton are being updated by owner Intrum Corp. with plans for a 116,000-square-foot addition connecting to the existing building.
