Water Sheets

Water Sheets reimagines the hot spring treatment center as a sequence of bands where the walls are born, organizing the entire building around the rhythm of solid mass and open space. Designed by Fernando Moncayo and Carlos Alarcon in Cartagena, Spain, between 2018 and 2019, the project lets the architecture itself frame the experience of thermal bathing. Between the spaces of these walls, the different thermal water pools are developed across the ground floor and basement, while the upper floor holds the rooms where bathers can spend the night.

The strength of the concept lies in how movement and stillness alternate. As visitors pass through the banded walls, the pools open and close around them, creating a measured progression from arrival to deep relaxation. This kind of spatial pacing is central to spa and bathing architecture, where the journey toward water matters as much as the water itself. The thermal pools, set at different levels, give the section real depth and invite bathers to descend gradually into the warmth.

Light, Steam, and the Murcian Horizon

From the upper rooms, bathers contemplate the panorama of the mountains of Murcia, with the steam of the thermal guides acting as a soft filter over those distant views. This atmospheric layering is a quiet but powerful device. Steam blurs the edge between interior and landscape, turning a simple window into a shifting, weather-like screen. The choice connects the building to the wider region of Murcia and its dry, mountainous terrain, anchoring an intimate program within a broad natural setting.

A facility of this type must balance demanding technical needs with a calm, restorative mood. Heated water, high humidity, and constant steam call for careful management of materials and ventilation, while the guest experience asks for silence, soft light, and a sense of retreat. The banded walls answer both, separating wet and dry zones while shaping the views. Like many works of contemporary Spanish architecture, Water Sheets treats climate and landscape as active partners in the design. The result is a bathing center where structure, water, and horizon are read as a single continuous gesture, inviting the body to slow down and the eye to wander toward the hills.
