The Way Up is a spiritual retreat set within a peaceful natural setting, designed to promote mindfulness and self-reflection. The overall concept focuses on creating a space that encourages a deeper connection to nature and the divine. By aligning with the rising sun, the structure positions its meditation areas toward the east, enhancing the opportunity for users to engage with the space at dawn.

Orientation and Spatial Experience

The design uses a deliberate orientation from west to east to allow individuals to meditate in harmony with the morning light. This thoughtful placement utilizes natural illumination to enrich the meditative state, offering users an experience infused with early-day energy. Upon entering, visitors are encouraged to transition by shedding clothing that symbolizes everyday life. This act fosters a psychological shift toward introspection, preparing them for a deeper engagement with their thoughts and surroundings.

Elemental Integration

The Way Up includes the four elements of nature within its elevations. The water element flows from the roof, guiding rainwater into the meditation area, representing a cleansing and restorative force. Fire is introduced through a cooking area and soft candlelight, creating warmth and intimacy. The earth aspect encourages people to feel connected to the soil and plants surrounding the retreat, while the air element is represented in an elevated resting area constructed of ropes, giving a sense of lightness and liberation.

Sustainable Systems

A Trombe wall is part of the heating system, supplemented by a firewood solution sourced from the surrounding area. This design helps maintain stable warmth, with tubes embedded beneath the floor to distribute heat effectively. The Trombe wall also allows for passive cooling by enabling the opening of lower windows. This method highlights a practical approach to temperature control in the space.

Energy and Sanitation Solutions

Lighting in the meditation area comes from LED lamps that operate without external power sources. The retreat utilizes a concept known as "potato power," where chemical interactions between metals and potato acids create energy. This solution reflects a commitment to sustainable practices. In terms of sanitation, the facility employs a urine-diverting dry toilet system that separates waste without requiring flush water, featuring ventilation pipes to manage odors and moisture. This setup demonstrates dedication to ecological responsibility.

The design emphasizes grounding elements that connect users to the earth. It invites them to interact with the natural surroundings, fostering contemplation and reflection.
