Caltun Shelter

The design of a new shelter at Cal?un in Romania’s Fagara? Mountains presents a unique challenge: creating a functional, sustainable, and resilient structure at an altitude of 2,160 me- ters. The site, known for its extreme conditions, required inno- vative thinking and a careful selection of materials. The cho- sen material, Cross Laminated Timber (CLT), was ideal for the harsh environment. CLT offers excellent resistance to heavy snow loads (2 tons/m²), is lightweight, and has impressive wind resistance, along with a pleasant wooden aroma that enhances the space’s sensory appeal. The shelter’s dynamic, wind-responsive shape reflects the region’s powerful gusts, while the aluminum sheet covering draws inspiration from the moss-covered stones of the site. Functionally, the building serves as both a first-aid room for the mountain rescue team and a tourist space, with the capacity to accommodate 19 visitors. This dual purpose responds to the critical need for a safe haven in one of Romania’s most accident-prone moun- tain areas. Strategically located to protect the nearby lake from pollution, the shelter’s platform doubles as an emergency helicopter landing zone. A photovoltaic panel on the roof en- sures energy independence, powering the structure through- out the day. By carefully selecting materials, respecting local conditions, and integrating functional design elements, this project embodies a new architectural attitude—a lighthouse for sustainable design in extreme conditions.
