This facility underwent a significant transformation to address extensive concealed water damage and structural deterioration that had developed over time. The project involved substantial demolition, reconstruction, and modernization efforts to restore the building and ensure its long-term performance. Significant moisture intrusion and rot throughout portions of the structure was discovered, requiring extensive structural repairs. The most challenging aspect of the project was the complete replacement of the structure surrounding and supporting the hot pool area, which had deteriorated from prolonged exposure to moisture. Other improvements included updating the HVAC and pool filter system as well as installation of new spray foam insulation, replacement of the burnt wood siding and trim, and new exterior windows and doors to match. A signature feature of the project was the installation of a custom multi-head rainfall shower system utilizing four oversized shower heads configured to function as a single immersive rainfall experience. The new pool system from Allen Pools & Spas was upgraded to a saltwater treatment system and the burnt wood siding and trim was from Nakamoto Forestry Products, which specializes in the rot-resistant shou sugi ban charred siding. The attic floors were repaired to support the new dehumidification unit and HVAC system while a new radiant heat boiler and basement ventilation system was installed to maintain a safe and sophisticated spa environment.
