Another phase for the OneNorth development project has been announced for Bayside.

Cobalt Partners and La Macchia Holdings, development partners based in Milwaukee, on Tuesday announced a proposed next phase for the OneNorth development at the northwest corner of North Port Washington and West Brown Deer Roads. Initial plans call for a single, mixed-use building with a health and fitness center, a full-service grocer and around 180 luxury apartments, officials said. The development has grown to $200 million, officials added.

The North Shore development has been in planning since the late 2010s. The first phase of construction started in 2023, when Stevens Construction Corp. broke ground on the nearly 200,000-square-foot mixed-use apartment building known as The Symphony. That project, which included the new North Shore Library and 98 apartments, was completed in August 2024.

In September, Matter Development and Moore Construction Services officially broke ground on Artalia Bayside, a $40 million senior community with 153 units, an addition to the OneNorth plan. The building will be operated by Koru Health, an affiliate of Matter Development.

“From the outset, our vision for OneNorth has been to create a vibrant, mixed-use destination that feels authentic to the community – walkable, social and easy for everyday life,” said Scott Yauck, president and CEO of Cobalt Partners, in a statement. “This next phase brings OneNorth’s promise into even sharper focus: an elevated living and working environment surrounded by exceptional amenities that people use on a daily basis.”

“OneNorth’s plan integrates luxury residential venues, boutique shops and restaurants, wellness concepts, reimagined workspaces, and the new North Shore Library around a central green plaza,” officials said.

The new North Shore Library is scheduled to open on Feb. 2, 2026, they added.

Cobalt Partners officials said they were in early stages of negotiations with tenants and will present conceptual building and site plans to the village in the coming months.

“We are excited about the prospect of working with village leadership to bring these great offerings to the community in a thoughtful manner and to continue the momentum of the placemaking that is OneNorth,” Yauck said.
