Step-by-Step Guide

1. Place the kitchen base module in the left corner on the lower floor. Ensure it lines up with the floor's edge to establish a neat cooking space.
2. Add countertop details: Position a wooden cutting board with a half-assembled sandwich on the right end, a kitchen towel beneath, and a paring knife beside it.
3. Install floating shelves on the left wall above the kitchen, placing decor items like a sunflower vase and pastel mugs.
4. Position the refrigerator with magnets against the left-center wall, ensuring the right edge is flush, and decorate with a bunny magnet and sticky notes.
5. Arrange a grocery bag with leafy greens and vegetables on the floor, touching both the floor and base module.
6. Set up the dining area by placing a long white table with a bench and two stools, ensuring precise spacing.
7. Build the entrance zone: Extend the checkered tile, set sliding doors, and add curtains. Place a wicker basket with bread loaves inside.
8. Position the TV console opposite the dining table, add a flat-screen TV, and tuck a potted plant into the corner.
9. Assemble a central bookcase divider to separate social and work areas and fill with books.
10. Install a spiral staircase in the lower-right corner, carefully aligning its twist and height for smooth connection.
11. Create a balcony retreat by affixing glass railings, placing chairs, a table, and decorating with plants.
