An online custom clothing and home goods seller based in Corktown is working to finance an up to $18 million expansion that would require demolition and building a new facility.

MyLocker.com LLC operates out of a cluster of three facilities next to the Trumbull and Porter Hotel, south of Michigan Avenue. Its growth plan would create 452 jobs, according to a Michigan Economic Development Corp. news release.

The newly built 108,902-square-foot building would house inventory, a robotic inventory system, offices, and shipping and receiving, the release said. It would replace a currently standing single-story office building at 1641 Porter St.

The Michigan Strategic Fund on Tuesday approved a $2.5 million performance-based grant to help MyLocker fund its expansion. MyLocker will also get a $4.2 million construction loan through the Michigan Strategic Fund and is working with the community development financial organization Invest Detroit on further financing, the release said.

MyLocker's three properties are at 1300 Rosa Parks Blvd., 1661 Porter St. and 1641 Porter, according to an MEDC memo on the grant assistance.

Messages were left with MyLocker seeking comment.

MyLocker moved its headquarters and 200 employees from Warren to Corktown in 2013.

Robert Hake founded the company in 1998. It got its start selling fleece blankets with water-resistant fabric. MyLocker started personalizing the blankets and then began online sales in 2005. A company claim to fame is creating software that automates the product customization process, according to the MEDC memo.
