About In Seclusion Spa Cois Abhann

Is spa cois abhann sa Phortaingéil é an tionscadal. Tá an dearadh suite laistigh de thírdhreach nádúrtha atá ann cheana agus baintear úsáid as toirteanna ailtireachta sreabhacha chun an tionchar amhairc a laghdú. Cuirtear isteach limistéir mhóra ghloinithe chun radhairc a cheadú idir na spásanna istigh agus an timpeallacht mórthimpeall. Cuirtear bailchríocha adhmaid agus urláir chloiche i bhfeidhm ar fud an taoibh istigh. Áirítear sa chlár sauna, jacuzzi, agus folcadán Turcach, atá leagtha amach chun sraith spásanna folctha a chruthú. Eagraíonn an leagan amach na feidhmeanna seo i ndáil leis an abhainn agus leis an talamh mórthimpeall.

Behind the Design

Unique Properties: This is a riverside spa design in Portugal that embodies serene seclusion. It harmonizes fully with its historic and natural surroundings, using low-profile architecture, expansive glass, timber interiors, and stone flooring to blur indoor and outdoor boundaries. Its strengths lie in immersive nature integration, warm materiality, and a layout combining sauna, jacuzzi, and Turkish bath, offering guests a profound, multi-sensory retreat deeply connected to the landscape.
Dimensions & Packaging: Single-story building with overall dimensions of 20 meters in width, 8 meters in depth, and 8 meters in height.
Tags: Landscape architecture, leisure spa, wellness facilities, low-impact design, indoor-outdoor connection, integration with nature, immersive experience
Production Technology: The spa was designed through careful site analysis, integrating gently with the terrain. Timber, beige stone, and low-iron glass were chosen for warmth, durability, and transparency. The process combined ecological sensitivity, modular planning for sauna, jacuzzi, and Turkish bath, and precise glazing to enhance visual connections with nature, creating a harmonious, immersive, and sustainable environment.
Design Challenge: The hardest part was balancing serenity with practicality—preserving the historic watermill while adding modern spa facilities. Internally, respecting the site’s history and ecology challenged design choices. Externally, strict codes, structural limits, and material availability required adaptation. Technology and environmental analysis guided solutions, ensuring minimal impact while creating a harmonious, immersive experience
Research: Type of research: design-focused experiential study. Research objectives: explore how architecture can promote deep relaxation and enhance the human-nature connection. Methodology: combining site analysis, material studies, spatial simulations, and daylight analysis. Data collection: through site photos, topographic drawings, and building equipment specifications. Research tools: cad models, 3d visualizations, material samples, and environmental sensors monitoring light, sound, and water interaction.
Inspiration: The inspiration came from the serene beauty of the Vez River and the timeless presence of the old watermill. I was drawn to creating a space that allows people to reconnect with nature and themselves, offering quietude without isolation. My motive was to design a spa that flows with the landscape, using natural materials and transparent architecture to blur boundaries, fostering a profound, immersive experience of calm, reflection, and harmony with the environment.
Project Duration: The project started in February 2025 and finished in June 2025
Operation Flow: The spa functions through immersive spatial design: guests move through curated areas—pool, sauna, jacuzzi, Turkish bath—experiencing gentle sensory transitions. Interaction arises from visual and tactile engagement with natural materials, light, and water. Key moments occur at floor-to-ceiling glazing, pool edges, and steam-filled interiors. By harmonizing with nature, it deepens relaxation, enhances well-being, and fosters a seamless, restorative human-nature connection.
