Prepare one strong first concept direction around a detached mother-in-law suite. Treat attached suite only as a fallback if the site cannot fit the detached option cleanly.
Primary concept
Modern two-storey residence plus detached mother-in-law suite. The suite should feel related to the main house, pool, outdoor sitting area, and Lao kitchen without losing privacy.
Fallback logic
If setbacks, septic placement, access, drainage, fill levels, pool position, or buildable envelope make the detached suite awkward, Vieng should show why and propose a connected/attached alternative as a practical correction, not as a separate full design track.
Design language
Modern flat roof, creative but buildable in Vientiane. One expression may carry a restrained Mediterranean/Italian feeling through proportion, shaded outdoor rooms, plaster/stone warmth, and quiet courtyard composition rather than decoration.
Expected first output
Site layout, draft floor plan, room relationship diagram, simple 2D massing/elevation direction, and a clear question list for Sam/Gary/client before detailed drawings begin.
