Uderns, Zillertal, Austria
A passive-house timber resort in the Zillertal built around a chlorine-free lagoon, where The Green Market replaces rigid mealtimes with all-day flexibility.
THE GREEN Lagoon sits at the heart of the resort, a chlorine-free natural swimming lake that self-purifies and stays open year-round, ice swimming included. Around it, locally sourced timber frames every building to passive-house standard. Kals marble lines the interiors. Forested Zillertal mountains fill the windows. The golf course begins at the property edge.
The Schultz family built THE GREEN to adapt to each guest's pace. There is no fixed dinner hour. The Green Market runs from morning to evening, so families, couples, and solo travellers eat when they want. Flora and Fauna split the wellness area into family and adult zones. It is family-friendly without being a children's hotel, contemporary without chasing trends.
The Zillertal ski area is the winter draw. Back at the resort, ice swimming in THE GREEN Lagoon sharpens the contrast. E-bikes charge at on-site stations for valley rides and alpine climbs in summer. The adjacent Golf Uderns course is steps from the lobby.
Hiking trails climb into the surrounding mountains directly from Uderns. The Kids Jungle Club keeps younger guests busy with its own water station and play areas. The resort also hosts seminars and creative retreats where the alpine setting is part of the programme.

The Green Market replaces the traditional hotel restaurant with a curated buffet that runs in long, overlapping windows. Breakfast from 7:30 to 10:30. Afternoon and evening service from 1:30 onward. No reservations, no rigid courses, no rush.
The kitchen works with regional farmers and artisanal producers across the Zillertal. Game meat comes from the hotel's own hunting grounds in the Karwendel and Rofan Mountains. The Evergreen Bar overlooks the lagoon through floor-to-ceiling glass, serving drinks and snacks on a wide sun deck. For a full gourmet evening, Genusswerkstatt sits 100 metres away at the Sportresidenz Zillertal, recognised by Gault&Millau and Falstaff.
The wellness area splits into two zones. Flora centres on THE GREEN Lagoon, a chlorine-free natural lake with self-purifying water treatment. An infinity pool sits alongside it. The Dress-on Sauna lets families share the heat together, no separate sessions needed.
Fauna is the adult counterpart. Indoor and outdoor relaxation areas open onto the sun deck. Treatments use sustainable natural cosmetics. Reusable spa shoes replace disposable ones. Waste heat from the cooling system warms the pools, closing the energy loop quietly underfoot.
THE GREEN does not treat sustainability as a trend. The Schultz family embedded it from the first blueprint. The entire structure meets passive-house quality, built with locally sourced timber. Geothermal probes handle heating and cooling. A wood chip system burns local wood. Solar panels line the roof. The resort generates most of its electricity through the group's renewable energy community.
The details add up. THE GREEN Lagoon purifies itself without chlorine, using resource-efficient water treatment. Waste heat from cooling feeds the swimming pools. Rooms stock refillable amenities. Spa shoes are reusable. E-bikes, e-cars, and e-shuttles charge at on-site stations. Game comes from the hotel's own Karwendel and Rofan hunts. Kals marble and regional timber replace imported finishes.
