On the edge of the fortified town of Naarden, healthcare is getting a new face. On the site where the old Naarderheem stood for many years, Heilijgers is building a center that is anything but traditional. A place where people recover, learn and work in an environment that moves with the future. “We are building not just a building here, but an environment that is right down to the details,” says project manager Wim Huenestein.
The new building of Vivium Care Group required a smart approach. While part of the old building was still in use, Heilijgers began the first phase of the project. “We continuously took into account the people still living there,” says Huenestein. “Although it soon became apparent that that wasn't really necessary. The construction fences soon had to be removed, because the residents loved being able to join in.”

The new Naarderheem consists of three building sections totaling 19,000 square feet. The lower two floors form an open plinth with the restaurant, exercise rooms, a gym and 150 workstations. Above that are four floors with 220 rooms for rehabilitation and long-term care. “The architecture is light and inviting,” says Huenestein. “Not a colossus, but a friendly building that fits into its surroundings.”
Behind the building is a strong piece of engineering: a thermal energy storage system up to 185 meters, completely gas-free and 330 solar panels on the roof. “That's healthcare real estate that's ready for the coming decades,” Huenestein says. “But it's the details that make the difference. There are views of the Shooting Fields, and daylight reaches even the core of the building through patios and large skylights.” The design comes from Vakwerk Architects. The three cubes are connected through a transparent plinth that encourages movement and meeting.
“Clients, visitors and staff intersect naturally here. That's exactly what Vivium wanted: an environment that supports recovery.”
Heilijgers became involved in the project after a selection process. “Vivium chose our plan because we think along, not just execute,” says Huenestein. “Everything revolves around trust. We build the very best result together.” Construction is on schedule. In early 2026, the first clients will move in. Then there will not only be a new rehabilitation center, but also Vivium's headquarters and a training place for future healthcare professionals. “A huge job, but Vivium is enthusiastic so far. And if soon the first residents come in and say it feels nice, then it will really be a success.”
