generate a building formed from three stepped rectangular levels with the following fixed massing level 1 the largest rectangle containing the bedrooms level 2 same width as level 1 but shifted backward to create a front terrace this level contains the living room level 3 the smallest rectangle shifted further backward in the same direction apply organic architecture with smooth curved lines and flowing transitions across all volumes while keeping the stepped geometry and relative proportions exactly as described place a rectangular glass bottom pool on level 3 positioned directly above level 2 so that the pool s glass floor becomes the ceiling of the living room the building should feel sculpted fluid and naturally integrated in its terraced form but the three level stepped massing must remain clear and unchanged
