MIDDLETON, Wis. — Spectrum Brands Holdings Inc. plans to expand its world headquarters building to accommodate growth over the next several years.

The consumer products company said plans call for a 30,000-square-foot addition to be made at the south end of its four-story, 220,000-square-foot headquarters, located at 3001 Deming Way in Middleton, Wis.

Groundbreaking set for next month, and the project is scheduled to be completed in the spring of 2017, according to Spectrum Brands. The expansion will be developed and owned by the Livesey Co., a Middleton-based commercial real estate developer that owns the building.

Spectrum Brands said the expansion also will bring new positions in administration, marketing and technology.

Spectrum Brands moved into the current building in October 2013. The location also houses several North American divisional operations, North American shared services and a state-of-the-art technology center to spur new product development for the battery, personal care and home appliances businesses. The Middleton facility was built to accommodate as many as 675 positions, a capacity that the company noted was reached nearly reached two-and-a-half years later.
