1. Basic built-in bunk bed. Houzz readers loved the custom, grown-up color of this built-in bunk bed. Several even wanted this space-saving solution for their guest rooms.
2. Texas tweens' crafts and homework space. An upgrade from the average play area, this room works as a combined homework and crafts space for tweens and teens. Plenty of custom storage — visible and hidden — keeps things neat and clean.
3. Cozy kids' window seat in North Carolina. In lieu of a playroom, a cozy nook with space for games and books like this one might be the perfect spot for your little one.
4. Dream Nashville tree house. Nearly every kid wants a tree house, and it's hard to dream up one better than this. The mix of modern design and pure playfulness (such as the bucket for raising and lowering treasures) makes for a dream two-story getaway.
5. Pink and purple done right in Connecticut. Purple and pink don't have to accompany an outrageous design. Houzzers saved this photo for its timeless take on two feminine colors.
6. Simple, elegant Kansas nursery. Although this lovely nursery was designed for a boy, Houzz readers enjoyed its unisex side. Soothing colors and simple patterns combine in a classic space that can easily transform into a toddler's room later on.
7. Lofted playspace in Massachusetts. Kids love secret hideaways, like this loft built for a girl. A homework station below and a playspace above help divide work time and playtime.
8. Colorado cabin kids' room. This dark sleepover space has just enough of a dungeon vibe to feel fun but not spooky. Stone walls, weathered wood and iron railings flow with the rest of the cabin's style.
9. Sophisticated San Francisco nursery. Houzzers couldn't get enough of the graphic patterns and playful colors in this nursery for a baby girl. While most of the furnishings could work in a master bedroom, the pom-poms and other fun touches keep the room youthful.
