As an abstraction of the surrounding Appalachian Mountain range rock in the landscape, the concrete volume of the spa emerges from the earth, creating a plinth to support a new thermal bath and expanded spa terrace.

The new thermal bath visually connects the infinite edge of the spa to Lac Gale below, creating a perceived visual reference to each plane of water. The bath includes a glazed underwater section, offering a view through the water and glass interface to the lake and mountains beyond.

As a unifying element and extension of the existing terrace, the bath realigns the view, and becomes a part of the tiered landscape, gradually building up the slope to the existing spa building. The expanded terrace creates multiple places for relaxation and seating amongst the landscape gardens, including a fireplace and stone agora seating area. The south facing terrace collects heat from the midday sun, radiating it from the stone surfaces, allowing it to operate year-round.

The concrete plinth contains a relaxation room hidden underground below the thermal bath. This relaxation room is clad with a curvilinear wood volume, with benches incorporated into the wrapping form. The room includes sun therapy lights and a sand-filled seating space ahead of the wood bench, providing a beach-like experience for users, and views towards the lake through a large glazed opening.
