Building Multi-Story Houses in The Sims 2 Pets (PS2): Not Possible

The PS2 version of The Sims 2 Pets restricts building to a single floor. There is no staircase tool or foundation system to add a second story.

You can still create spacious single-level homes with multiple rooms, but vertical expansion is absent.

Alternatives for Multi-Story Building

• The Sims 2 (PC/Console): Full build mode with floors, stairs, foundations.
• The Sims 3 / 4: Even more advanced building tools.
