Boys love to build. From their earliest years when they first place block upon block, to their teens when they are constructing even more elaborate buildings and vehicles. Toys that are tactile, engaging, and fun to play with will always capture their imagination. Even if they don’t choose to become architects or builders, these toys help them develop their fine motor skills and brain capacity while having a great time.

From straws to LEGO to bristle blocks to magnets, these building toys offer a range of materials for boys of all ages to use as they either follow the instructions or – more likely – use their imaginations to create wondrous structures…and then destroy them to start again. We’ve based our recommendations on only the real reviews out there, so you can rely on these toys to bring hours of fun.
