Designed by Gortemaker Algra Feenstra Architects, the new Expertisecentre and Service Building ’t Spant brings together a wide range of care and support services for Dutch healthcare and support organization Ipse de Bruggen within a compact footprint on the Craeyenburch Estate in Nootdorp, the Netherlands.
The project was realized in close collaboration with du Prie, Swinn, and Merosch and aligns a renewed care vision with a long-term sustainability approach, integrating energy neutrality, material efficiency, and spatial flexibility into a building that forms the social and functional heart of the estate.
Compact form and site integration
The design replaces a previously dispersed set of functions with a single, compact building, reducing overall material use while improving operational efficiency. Situated along the estate’s landscaped axis, the building strengthens connections across the site and creates a clear organizational structure for daily care activities. The compact massing limits heat loss, enhances energy performance, and supports the ambition to reduce the project’s environmental footprint from the outset.
Envelope and material strategy
The facade consists of prefabricated timber frame elements that allow for efficient assembly and minimal waste. Thermally modified timber cladding enhances durability and reduces maintenance, using FSC-certified timber for responsible sourcing and reduced embodied carbon.
Laminated timber beams in the atrium and climate-positive flooring contribute to a low-carbon profile, keeping emissions below five kilograms of carbon dioxide per square meter. This modular approach allows individual panels to be dismantled, supporting circular principles.
The building achieves an A+++++ energy label, generating all its energy on-site through a geothermal heating system and solar panels. A controlled ventilation system with heat recovery stabilizes indoor temperatures, while large windows and bright spaces minimize the need for artificial lighting, making the building energy-neutral and eliminating operational emissions.
Long-term efficiency
Service and maintenance emissions are reduced through the deliberate choice of durable, low-intervention materials. Thermally modified timber requires minimal treatment over time; the modular facade system allows localized repair without large-scale replacement; and energy-efficient pumps, fans, and lighting operate under smart controls to limit electricity demand. These measures ensure that the building continues to perform with low environmental impact over its life cycle.
The expert center houses departments such as physiotherapy, speech therapy, dentistry, behavioral specialists, and specialized physicians. In addition, the building provides space for offices, a conference center, and a restaurant.
Clear organisation and calm interiors
The interior concept focuses on recognizability and independence for clients. A clearly designed route, known as the “lint,” guides visitors from the restaurant to the various treatment rooms. Wall finishes create visual cohesion throughout the spaces and are reflected in the fixed furnishings.
Color accents highlight key areas along the route. The route is organized around a patio that provides daylight and orientation for clients and can also be used as an exercise garden for physiotherapy.
Soft architecture in a green context
The building is characterized by a soft architectural language with rounded corners and abundant natural light. Wooden facade elements and full-height windows give the building a friendly appearance that integrates with the estate.
Rather than an anonymous institution, it becomes a recognizable place with a human character, where the transition between inside and outside is seamless. On both sides, the building connects to the existing landscaped structure of Craeyenburch, making it accessible from every direction.
