Nieuwestad is the heart of Leeuwarden’s historic city centre. At its centre stands De Waag, one of the city’s most distinctive and iconic buildings. In the past, De Waag housed a public weighing house, where goods were weighed before being sold at the market. Dairy products, and butter in particular, played an important role in this trade. De Waag was therefore an important centre for commerce and social interaction. Although its original function has disappeared over time, the building remains a tangible reminder of the city’s rich trading history.

The entire Nieuwestad will be redesigned over the coming years. The open space in front of De Waag has been designated as the location for a special play feature. In 2026, Bureau B+B won the commission with a design that considers the historical layers of the site while adding a new story of its own.

The form is fluid and smooth like butter, and undulates like a droplet touching the surface of water. Several concentric rings come together to form a layered landscape, with each ring offering unique opportunities for play and interaction.

A gently sloping surface invites children to explore and experiment through movement. The different heights and shapes offer opportunities to sit, lie down, climb, slide, hide, discover or simply take a moment to relax.
