Intervention Concept
The design approach and façades underscore the underground-infrastructure character of the indoor shooting facility. Together, these elements reinforce the notion of a “trench,” a nod to historical defence strategies. Only a slit—no wider than the access lane—appears at ground level on the parade ground; the covered parking bays are tucked into the retaining wall, hidden from view.
Morphology
Conceived as a fully buried structure, the project meets the need for both discretion and noise reduction that such an installation demands. Only the guard-rails of the emergency exits will remain visible; the rest of the roof will be greened over and returned to its original state. The overall footprint is roughly 140 × 50 metres, or about 7,000 m².
Organisation
The indoor range is arranged on a single subterranean level.
Access to all rooms is via a vehicle-accessible circulation alley.
Entry to the shooting bays is through a changing room where users can handle and clean their firearms. An air-lock completes the sequence, leading to the various firing lines.
A shared module gathers a training dojo, storage rooms, an instructors’ office and an additional locker room.
A “technical backpack” houses the building-services plant, ensuring the proper operation of the facility—especially the ventilation of the shooting lanes.
