A new model of Hospitality –
DESIGNED FOR PEOPLE AND THE ENDANGERED SPECIES OF THE FOREST
A hospitality project shaped with a clear intention: to design a place that enters the landscape with respect and contributes to the life that already exists there. In the forests of Evrytania, the permanent residents of the ecosystem, birds, bats, pollinators, are under pressure.
From the beginning, the aim was to understand this living network and create architecture that supports it instead of displacing it. The design process started with a biodiversity study carried out with environmental engineers and specialists. We mapped the species, their habits, their vulnerabilities, and the conditions they need to survive.
The architecture follows a regenerative mindset.
This research set the foundation for the project.
Every decision, form, material, openings, structure, was organised around this core.
The result is a series of sculpted timber volumes that act as nests for both people and the endangered species of the region.
The façades incorporate nesting systems that provide safe habitats while preserving architectural sensitivity and spatial quality. Architecture becomes part of the ecological fabric of the forest, strengthening the species most at risk and allowing a harmonious coexistence between wildlife and visitors. A specialised study determined the height and placement of each nesting module according to the species’ needs and their level of interaction or non-interaction with humans, ensuring that every habitat is positioned with precision and respect for natural behaviour patterns.
Natural wood/timber and recycled steel are assembled with design-for-disassembly principles, allowing each component to re-enter the material cycle. The buildings operate off-grid, achieving nZEB performance through passive strategies, geothermal systems, BIPV integration, rainwater/snowwater harvesting, and cross-ventilation. Resource autonomy and circularity shape the project from start to finish.
The presence of the project changes with the seasons in a way that strengthens its relationship with the landscape. The triangular volumes echo the surrounding mountain geometry. Materials respond to seasonal shifts: oxidised steel blends with the greens and oranges of spring and autumn, while the deep tones of charred timber align with the dark, snow-covered winter forest.
The architecture becomes part of the colour palette of the terrain instead of standing apart from it. The project restores ecological corridors, stabilises the terrain, and reinforces existing habitats. It sets a direction for hospitality in sensitive environments, proposing a model where architecture actively contributes to the resilience of the ecosystem.
Trine Nests stands as the first example of regenerative hospitality in Greece. It proves that a retreat for visitors can also be a living refuge for the species that need it most.
“A retreat for people. A refuge for the species that need it most.
Trine Nests is a hospitality project shaped by a clear intention: to create a place that integrates respectfully into the landscape and enhances the life that already exists within it. In the mountainous regions of Evrytania, the permanent “residents” of the ecosystem—local fauna species such as birds, bats, and pollinators—are under increasing pressure.
From the very beginning, the project aimed to understand this living network and to develop an architecture that supports it rather than displaces it. The design process began with a biodiversity study, carried out in collaboration with environmental engineers and specialized scientists. Species were recorded along with their habits, vulnerabilities, and the conditions required for their survival.
The architecture follows a regenerative philosophy. This research formed the foundation of the project and informed every design decision: form, materials, openings, and structure. The result is a series of sculptural wooden volumes that function as “nests” for both humans and the threatened species of the area.
The façades integrate nesting systems, offering safe shelters without compromising architectural sensitivity or spatial quality. The architecture becomes part of the forest’s ecological fabric, supporting species at greater risk and enabling a harmonious coexistence between wildlife and visitors.
A specialized study determined the height and placement of each nesting unit, based on the needs of each species and their level of interaction—or non-interaction—with humans. In this way, each nest is positioned with precision and respect for natural behavioral patterns.
Natural wood and recycled steel were designed according to principles of design for disassembly, allowing each component to re-enter the material life cycle and actively incorporating circular economy principles into construction. The complex operates off-grid, achieving near-zero energy building (nZEB) performance through passive strategies, geothermal systems, building-integrated photovoltaics (BIPV), rainwater and snowmelt collection, and natural cross ventilation. Energy autonomy and circularity shape the project from beginning to end.
The presence of the project evolves with the seasons, strengthening its relationship with the landscape. The triangular volumes echo the geometry of the surrounding mountains, while the materials respond to seasonal changes: oxidized steel harmonizes with the green and orange tones of spring and autumn, while the deep tones of dark wood resonate with the dark, snow-covered forest of winter.
The architecture becomes part of the land’s color palette rather than standing apart from it. The project restores ecological corridors, reinforces natural ground conditions, and enhances existing habitats. It proposes a new model of hospitality in environmentally sensitive areas, where architecture actively contributes to ecosystem resilience.
Trine Nests stands as the first example of regenerative hospitality in Greece, demonstrating that a place of retreat for visitors can simultaneously function as a living refuge for the species that need it most.
