(AP) — White House spokesperson Davis Ingle said the new firm was needed because the project is moving into a new stage.

The firm is Washington, D.C.-based Shalom Baranes, and it has worked on several federal buildings, including the Pentagon and Treasury building, according to its website.

Ingle said the firm’s work has shaped the “architectural identity of our nation’s capital for decades” and its experience will be an asset to the ballroom construction.

The initial firm, McCrery Architects, remains on the project as a consultant.

The Washington Post was first to report on the development.
