Creator 3in1 Medieval Castle Toy to Tower or 31120

The LEGO Creator 3in1 Medieval Castle Toy to Tower set 31120 was released in 2021. It transforms into three different models and comes with 1,426 pieces. Retiring in 2024, this set is supplied sealed by BuyMyBricks.
In depth

The full description

The LEGO Creator 3in1 Medieval Castle (Set 31120) is a versatile building experience that captures the romance of castle architecture with genuine build variety. This factory-sealed, retired set offers three distinct models in one box, a challenge that rewards creative builders and collectors alike. With the set now retired, this is a rare opportunity to own a piece of LEGO history that’s never been opened.

What You Get

  • Complete, factory-sealed LEGO Creator 3in1 set 31120
  • Three buildable models in one set, Medieval Castle, Tower, and alternative configuration
  • All original pieces, instructions, and packaging intact
  • Retired set, no longer in production
  • Verified authentic by BuyMyBricks

Why This Set

The Creator 3in1 range is celebrated for giving builders genuine choice. Rather than a single static model, you’re looking at multiple complete builds from a single set, each one substantial enough to warrant display. The Medieval Castle theme has enduring appeal; whether you’re drawn to fantasy worlds, historical architecture, or simply the satisfying challenge of complex builds, this set delivers.

Building experience matters, and 3in1 sets force you to think creatively. You’ll work through one model, then deconstruct and rebuild into something entirely different. It’s engaging in a way that single-model sets sometimes aren’t. Once built, each configuration stands as a display piece worthy of shelf space, detailed enough to hold interest, distinctive enough to stand out among other LEGO creations.

As a retired set, 31120 is no longer available through standard retail channels. For builders and collectors seeking sets that are out of print, finding one still sealed represents both rarity and the assurance that every element remains in pristine condition.

Condition Guarantee

This set is factory-sealed and has been verified by BuyMyBricks. We stand behind every sealed set we sell. Every piece inside is guaranteed to be complete, unbuilt, and in original condition. The box, instructions, and packaging are untouched. If you decide to build it or keep it sealed, you’re starting from absolute zero, exactly as it left the factory.

Shipping & Returns

Free tracked UK delivery on orders over £85. If you’re not entirely satisfied, returns are accepted within 30 days. We want you confident in your purchase.

Common questions

The things people ask

Is it genuine and factory sealed, and what if it is not?
Every set is checked before it is listed: the factory seals and tape first, then the corners and edges, and anything worth knowing about the box goes on the listing. If a set from us is not genuine and factory sealed, tell me and I refund in full and pay the return postage. We sell sealed retired sets and nothing else, so there is no opened or used stock for yours to get mixed up with. Returns for any other reason are within 30 days, sealed, as the returns policy says.
When will it arrive?
Order before 3pm on a working day and it goes out the same day, tracked and insured. UK orders arrive within 1 to 3 working days, and you get the tracking number by email as soon as it is on its way. Tracked UK delivery is free over £85.
How is it packed, and what if the box arrives damaged?
The set box travels inside a second carton with fill, so the courier handles the outer box and not the one you are keeping, and every parcel is insured to its full value. If it still turns up damaged, photograph the outer packaging and the set box before you unpack any further, then email support@buymybricks.com with the photos and your order number the same day. We reply the same working day with a replacement if we have one or a full refund, and we deal with the courier claim ourselves so you do not have to.
Do you ship outside the UK?
Yes to the United States and Canada, with tracked and insured delivery costed at checkout before you pay. We do not ship to the EU at the moment. Everywhere in the UK is covered by the standard tracked service.
Can I return it?
Yes, within 30 days of delivery. If it arrived damaged or not as described, tell us and we pay the return postage and refund in full or replace it. If you have simply changed your mind, the set needs to come back sealed and as it arrived, and the return postage is yours. The refund goes back to the card you paid with within 3 working days of the set landing back with us. Use a tracked service so there is proof of delivery.
Is there a discount code?
Yes. Join the email list on any page and your first-order code comes through in the first email, along with what has just landed. We do not print the code on the site, so the list is the way to get it.
Can I pay in instalments?
Yes. Klarna Pay in 3 is at checkout: three equal payments, no interest and nothing extra to pay. Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay and Shop Pay are all there too. Payment is handled by Shopify Payments and we never see your card details.
Is it going to be a gift?
Tell us in the order notes at checkout and no prices or invoice go in the parcel. Sending it straight to them is fine: put their address as the delivery address and keep yours as the billing address.
Can I have a VAT invoice?
Yes. We are VAT registered and every price on the site already includes VAT. Reply to your order confirmation asking for one and it comes back the same working day. For a business or bulk order, email support@buymybricks.com before you buy and we will sort an itemised invoice.
Not the set you want?
Tell us the set number and we will look for a sealed one through the trade. If we find one at a sensible price you get an email with the link before it goes on the site. Ask us to find it.

Not answered here? Email support@buymybricks.com or ring 01904 900212. A person reads it, usually the same day.
