The development features retail and restaurant space, a 205-room Buffalo Marriott Harborcenter Hotel, as well as two hockey rinks that are the home of the Buffalo Jr. Sabres of the Ontario Junior Hockey League, the Canisius Golden Griffins of the NCAA, and the Erie Kats of the National Junior College Athletic Association.

The beginning concept for the building, specifically the dual ice rinks and parking garage combo came after Buffalo Sabres chief development officer Cliff Benson led a group of team officials to Washington, D.C. to view the Washington Capitals practice facility, the Kettler Capitals Iceplex.

[3] The complex, which is built on top of a parking garage, has seating for 1,200, a training center, proshop, and is home to many area teams.

[4] Construction of the 20-story Harborcenter began in March 2013,[5] the same month the Webster Block was purchased from the City of Buffalo for $2.2 million.

[6] The building was built by Mortenson Construction with ICON Venue Group serving as the project manager.

[7] The building's hockey rink portion topped out on June 25, 2014, as the last structural beam for the hotel was put into place.

The building was pledged by Pegula and others involved upon obtaining the property to open at the time by September 2014 making it one of the faster projects in the area.

On September 10, 2019, Pegula Sports and Entertainment reached a 10-year naming rights agreement for the building with Lake Erie College of Osteopathic Medicine (LECOM).

The Rinks are also the home to the Academy of Hockey and the Harborcenter Cup as well as serving as the Buffalo Sabres' practice facility.

[citation needed] In 2015, the NHL Scouting Combine was moved from Toronto to Harborcenter under a two-year pact.

[27] From June 22 to July 3, 2017, rink 1 hosted a charity event known as 11 Day Power Play, which set a world record for the longest continuous hockey game.
