About Us

We’re Block Party Co. — a Jacksonville-based, mom-built business bringing LEGO®-inspired, sensory-aware birthday parties straight to your door. We believe every child deserves a celebration that’s creative, inclusive, and thoughtfully planned — and every parent deserves to enjoy it, stress-free. With organized rotations, engaging stations, and sensory-aware design, we make sure every child can join the fun.

Our Inspiration

Block Party Co. was born after planning a LEGO®-themed birthday party that… missed the mark. We saw the gap between what parents wanted (organized, engaging, sensory-aware fun) and what was being offered. So we built a better way: a stress-free birthday experience where creativity thrives, chaos is managed, and kids leave with unforgettable memories (and maybe a few mini-figs too).

How It Works

Our parties are built to be simple, flexible, and completely customizable. Every package includes core build stations, and from there you can add on the extras that feel right for your child and your guests. Whether you’re planning for a handful of builders or a full house, you’ll find an option that meets your needs—and lets you shape the experience your way.

Our parties are designed to engage growing minds.

Our parties are designed to keep young minds engaged through problem-solving challenges, step-by-step guided builds, and opportunities for planning, decision-making, and teamwork. By blending structure with open-ended play, we create a balance that keeps kids engaged, learning, and having fun without overwhelm.
