Frequently Asked Questions

Are these official LEGO® products?

No — and we are upfront about that. BuildMOC sells independent, unbranded building sets produced by specialist manufacturers — original boxed kits in their own right. We are not affiliated with, sponsored by or endorsed by the LEGO Group; LEGO® is a trademark of the LEGO Group. What you get is high-quality ABS bricks on the same standard interlocking system, full instructions, and detailed display-worthy designs — at a price that isn't inflated by a brand badge.

What does MOC mean?

MOC stands for “My Own Creation” — a term from the building community for models designed outside the official big-brand ranges. Our MOC sets are original or reimagined designs produced as complete boxed kits with full instructions.

Are the blocks compatible with major brick systems?

Yes. Our sets use standard interlocking-brick dimensions, so they clip together with the major brick brands and any compatible bricks you already own.

Are instructions included?

Yes — every set includes full step-by-step instructions, either printed in the box or as a digital manual. If your manual is missing or damaged, contact us and we will send a digital copy.

Are the bags numbered?

Most larger sets arrive with numbered bags that match the instruction stages. Some smaller sets use unnumbered bags sorted by piece type. If bag numbering matters to you for a particular set, ask us before ordering and we will check.

Do sets arrive boxed?

Yes — sets arrive as boxed kits. Packaging is plain or manufacturer-branded rather than big-brand retail boxes; that is part of how we keep prices down. Product listings state the packaging type where it differs.

Are figures included?

Only where the listing says so. Sets that include figures state the number included in the title or description — for example our display books include full figure sets. If a listing does not mention figures, none are included.

What age are the sets suitable for?

Most of our display models are adult builds rated 14+, with small parts throughout. Our magnetic tile sets are designed for ages 3+. Each product page states the recommended age.

What happens if a piece is missing?

We will put it right. Visit our Missing or Damaged Pieces page, send us the details, and we will send replacements or arrange another resolution — no need to return the set.

Where are orders dispatched from?

From our UK warehouse. Orders placed before 2pm Monday to Saturday are dispatched the same day.

How long does delivery take?

UK delivery is free and typically arrives within 1–2 working days of dispatch, fully tracked. See Delivery Information for full details.

Can completed models differ slightly from the images?

Occasionally, yes. Manufacturers sometimes revise piece colours or minor details between production runs, and lighting in photography can differ from real life. The design, scale and piece count you see listed are what you will receive; small cosmetic variations can occur.
