A TIMBER CONSTRUCTION IN BEAUTIFUL SURROUNDINGS

In the scenic landscape of Ebeltoft in Denmark, Campus BØGEHØJ has been expanded with a new residential wing. The building features 80 modern rooms, conference facilities, a bistro, and shared spaces designed to strengthen Campus BØGEHØJ’s role as a gathering place for Salling Group’s students and employees.

The project was designed by C.F. Møller Architects, with a focus on creating a structure where natural materials, simplicity, and functionality meet. The building is constructed from Cross-Laminated Timber (CLT) and glulam, and according to CLT Denmark, the project consists of approximately 7,500 m² of CLT and 135 m³ of glulam.

To support the structure’s weight limitations, Hi-Con supplied slender sills made of Ultra High Performance Concrete (UHPC), a material that combines slender design, high strength, and long durability in one solution.

"We’ve been very satisfied with the collaboration. Hi-Con has been professional and solution-oriented throughout the process."

HI-CON’S UHPC AS THE SOLUTION

With a CLT structure, it was crucial to choose materials that maintained the building’s light architectural expression while meeting strict weight requirements. For this reason, Hi-Con was selected to deliver UHPC sills - an elegant and technically strong solution that integrates perfectly with the timber construction.

UHPC is an innovative material that combines low weight with high strength and long durability.

For Campus BØGEHØJ, Hi-Con produced 122 UHPC sills with a plate thickness of only 50 mm, in a light tone that harmonizes beautifully with the building’s overall architecture.

WHY IS UHPC IDEAL FOR TIMBER CONSTRUCTION?

Timber and UHPC are a natural match when the goal is to create lightweight, elegant, and fire-safe buildings. While CLT contributes warmth, low weight, and a natural aesthetic, UHPC adds technical strength, refined aesthetics, and durability.

The material’s slender and refined profile makes it possible to maintain a sense of lightness in the architecture, even in large cantilevers or long spans. At the same time, UHPC is fire-resistant and can meet strict fire safety requirements without additional fire coatings, which are often challenging for timber structures. Its dense, non-porous surface also makes UHPC structurally maintenance-free, reducing long-term operational costs and ensuring consistently high quality throughout the building’s lifespan.

When timber and UHPC are combined, the result is a building system that brings together the best of nature and technology. A structure that appears light yet lasts for generations.
