The O_CASELLA cabin is a prefabricated wooden shelter designed by Atelier LAVIT, the Paris-based architecture and design practice founded by Marco Lavit. Located in a spectacular landscape on the eastern plain of Corsica, France, the cabin was conceived to allow for full immersion in nature while maintaining comfort and protection. The name O_CASELLA is a play on the word "casella," which means "little box" or "shelter" in Corsican, reflecting the cabin's functional and minimalist nature. The design of O_CASELLA is based on two distinct, yet connected, modular volumes: a living module and a pergola. This structure addresses the demands of the warm Mediterranean climate by creating large, shaded areas for outdoor living. To minimize cost and environmental impact on the remote site, the entire cabin was prefabricated in a wood workshop. The modules were then transported fully assembled to the location, significantly reducing on-site construction time and disruption. The closed living module contains the kitchen, bathroom, and a flexible living/sleeping area. It provides framed views of the surrounding wild Corsican mountains and sea through large windows. The open-air pergola provides a ventilated and shaded space for outdoor relaxation, reading, or contemplating the landscape. A movable, mashrabiya-style shutter on a rail system allows occupants to regulate sunlight and air flow. The exterior structure and cladding are made from local Corsican larch (laricciu), a lightweight yet strong wood that contributes to the cabin's portability and durability. The interior walls and ceiling are lined with MDF wood, creating a cozy and protective atmosphere. A generous covered pergola extends the living space outdoors, with an outdoor shower providing an even more direct connection to nature. A steel beam on the façade serves a dual purpose: it hides the rail system for the sliding shutter panel and acts as a gutter for collecting rainwater. The movable mashrabiya panel offers passive cooling and sun protection. The modular system allows for flexibility in installation and configuration, showcasing a forward-thinking approach to sustainable architecture.
