Watchtower by next serves as Viewing platform and bat Habitat

NEXT Architects has completed the 26-meter-tall Watchtower Einderheide in Bergeijk, designed to offer visitors a panoramic view of the Brabantse Kempen forest while serving as a habitat for local bat species. The lookout tower integrates both recreational and ecological functions in a modest yet iconic structure that enhances the identity of Einderheide. The design features a spiral staircase leading to the viewing platform, where visitors can experience the forest from various heights. The structure, utilizing laminated larch and pine wood, includes multiple openings and notches at different levels, offering unique perspectives as visitors ascend. The tower’s characteristic shape allows for unobstructed views through and above the forest canopy.

next integrates Niches and cavities into the wooden structure

In addition to its role as a viewing platform, the tower is designed to support the bat population by providing diverse habitats. Niches and cavities are integrated throughout the wooden structure, offering spaces for roosting, mating, and nesting. These features, developed with ecological advice from Jeroen Mos, replicate natural conditions, blending seamlessly into the forest environment. The wood used in the design, particularly laminated larch and thermally preserved pine, contributes to this integration, providing both structural stability and natural rough surfaces for bats to grip. The tower’s base is made of a concrete foundation, which serves as a winter roost for bats. This nature-inclusive design follows other ecological projects by Amsterdam-based practice, NEXT Architects, such as the Bat Bridge and the Hopovers at De Centrale As.

Commissioned by the Municipality of Bergeijk and supported by the Province of North Brabant and Boskalis, the project involved collaboration with WSP, Mos Ecological Advice and Research, and H+N+S landscape architects. The Watchtower Einderheide stands as a functional landmark within the forest’s recreational network, balancing human interaction with wildlife conservation.
