Phase I: The mid-terrace features a prefabricated steel container pool vessel engineered into the site’s retaining scheme. Structural sub-grade preparation accounts for concentrated point loads, utilizing a reinforced concrete vault and engineered gravel bedding layer to ensure uniform ballast distribution and prevent differential settlement. Vertical grade change is mediated through structural retaining walls and concrete flatwork.

Phase I: An architectural hardwood deck platform surrounds the container pool, constructed with concealed joist isolation systems and moisture-barrier membranes to withstand continuous aquatic exposure. The adjacent outdoor kitchen integrates gas, electrical, and drainage supply lines cast directly within the primary sub-slab foundation.

Phase II: The detached backyard office structure was executed without disturbing Phase I hardscapes or subterranean utilities. The annex features an insulated building envelope with custom exterior cladding, low-E glazing, and Birch wood interior finishes, positioned to frame visual sightlines across the pool deck while maintaining acoustic separation from the primary residence.
