How a building is structured fundamentally determines how efficiently its space functions. Key factors include movable walls and built-in fixtures, soaring ceilings, expansive windows that flood interiors with natural light (or daylight-quality lighting), and thoughtful acoustic design. Two remarkable projects demonstrate how purposeful spatial design creates flexible environments that adapt to the diverse demands of modern work.

Circular pilot project "The Cradle"
At the heart of Düsseldorf's Media Harbour—a district defined by striking contemporary architecture—the state capital saw the completion of its first hybrid timber office building in 2023. Known in professional circles as a "landmark project for the real estate industry," "The Cradle" was designed by HPP Architects for Interboden Group. As a circular pilot project, it has already earned numerous architecture awards and accolades.

Creative work in an inspiring atmosphere Inside, the innovative office building unfolds as a light-filled, open, and transparent space. Spanning approximately 7,200 m², it offers ample room for creative collaboration. The design faithfully implements the Cradle to Cradle® principle—ensuring that all building materials and components are fully recyclable.

Superior acoustics in a multifunctional foyer
The bright, open foyer features multiple rotating wooden slat elements that visually divide the space into two separate zones, making it equally suited for events and presentations. The design statement comes from Troldtekt® acoustic panels mounted on the soaring ceiling—crafted from FUTURECEM™ cement, which significantly reduces environmental impact compared to conventional cement alternatives. These panels effectively absorb sound, counterbalancing the reflective hard surfaces throughout the space.

Policing for the future
In Hamburg's Alsterdorf district, AH+P Architects has delivered a striking new facility for one of Germany's most advanced police academies, developed for the Ministry of the Interior and Sport. The boldly cantilevered upper floors of "House A" command particular attention.
A cutting-edge training hub Spanning five floors—two below ground—the academy occupies approximately 10,000 m² and accommodates 1,500 trainees and students, supported by around 400 staff members who prepare them for active duty. The interior houses state-of-the-art lecture halls, conference spaces, training apartments, storage facilities, and a vehicle hangar. A fully equipped crime scene apartment enables hands-on evidence-collection practice. The design philosophy is straightforward: comfort fuels productivity and learning. This principle shaped every interior decision, from advanced technical systems to an open, welcoming aesthetic. Extensive glazing creates transparent sightlines along corridors, while integrated seating nooks recessed into light-colored walls offer flexible congregation spaces. Trainees can claim these informal gathering spots outside formal classrooms and common areas.
The grey acoustic panels from Troldtekt® Line Design, mounted along corridor ceilings, deliver striking visual impact while solving acoustic challenges.

Acoustic panels as design
statement Acoustics are critical in open-plan spaces dominated by hard materials. Even sparsely furnished rooms benefit dramatically from Troldtekt® acoustic solutions, which deliver superior sound absorption. These panels are breathable, diffusion-open, hypoallergenic, and built to last. Manufactured in Denmark from responsibly sourced wood and cement, they meet the highest environmental standards. Troldtekt holds both FSC® (FSC®C115450) and PEFC/09-31-030 certification, and the acoustic panels achieve Cradle to Cradle Certified® Gold status.
