About the LEGO River Steamboat set

A Mississippi paddle steamer with three decks, 69 cm long and with a stern wheel that really turns. A mechanism links it to the modelled steam engines in the hull, so the pistons run when you move the wheel. The ornamented superstructures with their railings and columns are what give the model its character.

The hull and the decks are clearly separated sections; most of the 14 hours goes into the ornamentation. 4’090 pieces sounds like more than it feels, because many of them are small and quickly placed. Finished, the ship is narrow but long and tall. To display it you need a shelf with height, not just width. Released in 2025 and currently in the shops.

Questions about the BlockAbo rental model

How does BlockAbo actually work?

You pick a set from our collection and we send it to your door for free. You build it, keep it as long as you like, and send it back when you are ready for the next one. After a month at the earliest, with no upper limit. Then you choose your next set.

What does BlockAbo cost and what is included?

There are three options: the single rental at a one-off CHF 42.–, the monthly plan at CHF 39.– per month and the yearly plan at CHF 29.– per month. Included are the complete set, the instructions, delivery to you and the cleaning. You cover the return, and the label is already in the box.

Can I cancel the subscription at any time?

Yes. The monthly plan can be cancelled to the end of any month, with no reason and no notice period. You send the set back and that is that. The yearly plan commits you for twelve months and costs about a quarter less per month in return.

How hygienic are rented LEGO sets?

Every set is washed at 30 °C with soap after it comes back, dried, and checked brick by brick for completeness. Only then does it go out again. So you never get a set somebody else has been through unchecked.

What happens if pieces are missing or break?

Up to ten lost small pieces are no problem and are included in the price. It happens, vacuum cleaners are merciless. We only get in touch for larger damage or missing large pieces. You do not have to go over the carpet with tweezers.

How fast does the set reach me?

Orders placed before 14:00 go out the same working day. After that Swiss Post usually takes one to two working days. We deliver anywhere in Switzerland and delivery to you is free.

Why is renting more sustainable than buying?

A LEGO set is usually built once and then sits on a shelf or in a cellar for years. With us the same set passes through eight to ten people. For the same number of sets built, that is up to 90 % less newly produced plastic.
