A multi-tiered central courtyard connects to flanking cylindrical towers via elevated cardboard suspension bridges. Painted in soft pastel shades using zero-VOC, non-toxic pet-safe acrylic paints, this project turns cardboard into an enchanting fantasy playhouse. The color scheme features pastel pink, lavender, sky blue, and crisp white.
Step-by-Step DIY Assembly
- Source Heavy Cylindrical Tubes: Obtain 8- to 10-inch diameter heavy cardboard concrete form tubes (Sonotubes) or roll thick corrugated cardboard into cylinders.
- Build Central Courtyard: Join two rectangular boxes into a central 2-story palace, cutting side entry arches that align with the round turrets.
- Craft Conical Roofs: Cut large cardboard circles, slit them to the center point, overlap edges into a cone shape, and glue atop the round turrets.
- Connect Skyway Bridges: Build open U-shaped cardboard walkways spanning between the central palace and outer turrets.
- Paint with Non-Toxic Paints: Coat the exterior with zero-VOC, non-toxic water-based acrylic paints, allowing 48 hours to dry completely before cat use.
