Forget one space station — this is the whole solar system on your desk. CaDA's The Solar System is an 865-piece brick build that assembles into an orbital display of the Sun and planets, easily the most ambitious set in the range and a genuinely satisfying multi-session project.
What's in the box
865 interlocking bricks forming the Sun, planets and their orbital arms
Clear picture-led instructions, no glue or paint required
Compatible with other major brick-building systems
Best for
A weekend project for space and astronomy fans, solo or as a family build
A striking display piece for a shelf, desk or classroom once complete
Builders (8+) ready to step up from smaller brick sets
With hundreds of pieces and a full planetary line-up to assemble, it's a proper sit-down project — and one that earns its spot on the shelf once it's done.
Our cosmic neighbourhood in brick form. Pair it with the CaDA International Space Station for a full orbit-to-planet display.

Are CaDA bricks compatible with other brick brands?
Yes — CaDA bricks are made to the same standard dimensions as the other leading brick systems, so they clutch and combine with whatever's already in the box under the bed. Mix them freely; nobody will know.
Is anything else needed to build it?
No. Everything's in the box — bricks and clear printed step-by-step instructions, with no app to download, no glue and no paint. A brick separator makes undoing a mistake easier, but it's a convenience rather than a requirement.
What age are these suitable for?
It depends on the piece count, so check the details above for this particular set — the smaller kits suit a confident younger builder, while the bigger ones run to several hundred pieces and are generally aimed at 8 and up. All of them work perfectly well as an adult project, which is how a fair few of ours are actually bought.
Is it just for display, or can it be taken apart?
Either. These are built to sit on a shelf and look the part, but they're standard bricks — nothing is glued, so it can come apart and go back together, or get absorbed into something else entirely.
