A coherent three-stage transformation designed to advance with the owner’s budget without losing the final architectural idea.
One architecture, designed to be built over time.
The project begins with an existing 776-square-foot, one-story residence. Rather than treating each budget phase as a separate intervention, Group-S organized the work as one continuous design whose structure, circulation and material language anticipate the completed home.
Phase One—now under construction—adds approximately 1,140 square feet at the rear and establishes a four-car tandem garage. Phase Two introduces the ADU within the planned composition. In Phase Three, the original house is removed and the two-level primary residence is completed.
Expand
Complete the ADU as the next independent step within the larger architectural framework.
Unify
Replace the original house with the two-level primary residence and complete the full composition.
Primary residence
A new street presence
Each phase is useful on its own and precise about what comes next.
The light metal-clad volume, transparent connector and warm wood element remain legible as distinct parts. Together they create a single residence whose final form is already embedded in the first construction phase.
