Hidden beneath the upper pavilion, the lower level unfolds as a contemplative retreat, responding to the sandstone base with ochre-pigmented concrete and intimate courtyards. A cutout pool, reminiscent of a natural waterhole, is embedded within the ochre courtyard floor, flanked by deep ochre boulders and native planting that echoes the material palette. The experience of descending through the oak portal along the tall stairwell, with shafts of light washing the textured walls, reveals this level in a dramatic, almost poetic gesture — a secret revealed gradually to those who inhabit the house.

This undercroft hosts a sauna in western red cedar, a steam room in matching ochre concrete, a bespoke American oak dining table, and an intimate office nestled among integrated planters. Low-level windows reveal the sandstone rock face, reinforcing a strong connection between architecture and geology. Courtyards and terraces borrow distant landscape while maintaining privacy, each space conceived as a sanctuary for contemplation, renewal, and family life.

Together with the upper pavilion, this level completes a dual personality: the house is both a light-filled, elevated street-facing presence, and a grounded, introspective retreat. The upper and lower levels are distinct in material and atmosphere, yet intimately connected through thresholds, stairs, and framed views — revealing architecture as both experience and revelation, where discovery is part of dwelling.
