Step-by-Step Guide

1. Place the lower deck and upper terrace edges: Ensure the pink lower platform covers the entire area and the light-beige corner wall fits at the back. On the left, align the pale wooden slat pad flush with the lower platform's left-front corner. Leave room on the right for a door and welcome mat. Align the upper terrace's curved front to match the final image.
2. Install the staircase and rails on the left: Add the staircase rising diagonally from the lower left to the upper floor. Attach lavender-blue handrails on both sides, making sure their rounded ends end just above the floor. Place a potted monstera beneath the stairs.
3. Add the glass double doors, welcome mat, and sidewalk sign: Center the grid-pane double doors under the balcony's curve. Place the cream welcome rug horizontally in front and position the A-frame chalkboard sign angled outward on the right.
4. Build the cozy lounge: On the lower-right, place an orange-peach loveseat facing left, with a pastel blue heart pillow on the right cushion. In front, position a coffee table with a slim green bottle and a vase of flowers.
5. Assemble the “mochi love” counter and heart chair: Add the counter with the “mochi love” panel facing outward. Position a pink heart-back chair diagonally on the left. Behind, hang a wall shelf and a display box.
6. Ring the upper terrace with rose planters: Wrap the upper balcony with flower boxes filled with red-pink roses and greenery, starting above the stairs and ending near the potted tree.
7. Set the dining alcove and wall cabinet (upper left): Position a round table with a cream cloth, goblets, plates, pastries, and a rose bouquet. Add a heart-back dining chair. Against the back wall, fit a recessed cabinet stocked with bottles, a second bouquet on the sideboard.
8. Build the performance stage: Position a small raised platform as the stage. Arrange four floor spotlights pointing inward, and mount ceiling track lights aimed at the stage. Hang a soft poster above.
9. Place the musician desk, the singer’s mic, and the dancing couple: At the stage’s back, place a desk with a computer, a potted plant, and the gray cat with headphones. Set a mic stand for the white cat vocalist in the front-right. Nearby, position a cat couple mid-dance.
10. Finish the right terrace: Add a glass-pane door on the upper-right with a golden step below. Anchor a potted citrus-style tree on the balcony corner.
11. Populate the ground floor: Place the brown and white cats walking toward the "mochi love" sign. Add a side table with a vase near the counter.
12. Drape the multi-color fairy lights: String pastel fairy lights from rear left to right over the rose planters and doors. Ensure all elements are aligned and tidy.
