10,000 bricks & more…

In September and October 2025 Hari built five LSP kits and had many thoughts about it.

The thing about LEGO® Serious Play® is that it takes a lot of bricks.

A lot of bricks.

We built our first two kits from a combination of the official LSP kits from Lego.com. We spent an afternoon sitting on the kitchen floor tearing open little bags of bricks and dumping them into Lay-N-Go bags.

But somehow, between building those kits and building the next set, things changed.

So we had to improvise a bit.

First we had the problem of the bags - Lay-N-Go weren’t shipping to the UK anymore and we didn’t have time to get a friendly American to act as an intermediary and send things on to us.

Luckily we came across the Stuffel Store on Etsy who make a version of the same sort of bag right here in the UK. It’s a little less practical (no cover flap for the drawstring) but a lot more colourful!

On to the bricks.

When we’d built our first two kits we’d also added some random bricks abandoned by (stolen from) the kids to bulk up the bags, so things in our kit bags weren’t exactly by the book anymore.

First of all we had to know what exactly was in there.

A local teenager doing some summer work counted all the bricks in one kit for us - all 1911 of them. They even documented it into a Google Sheet, which I turned into a CSV and checked against Pick a Brick to see if we could fake our way to the kits.

But that turned out to be even more expensive.

We were tipped off to 35kg of LEGO® bricks going cheap on Facebook marketplace. It wasn’t a bad price but it became much less cheap when Aaron accidentally drove our borrowed car through a bus gate while picking it up and accrued a £160 fine.

But we had 35 kilos of bricks, and surely that would be enough right?

You’d think so.

But it wasn’t. Or, rather, there weren’t enough plain old standard bricks. Like the trusty 2 x 4 standard brick.

According to our spreadsheet out standard kit contains over 200 of those in a variety of colours. When we started extracting what we needed from the 35kg haul, once thing we didn’t find many of were 2 x 4 standard bricks.

We needed 230 of the 2 x 4s and 110 of the 2 x 2s - instead we had 87 of the former and 89 of the latter.

Hari sorts the bricks

Given we were expecting each kit bag to serve as building material for 6-8 people, and the first activity we ask people to do is find 6 of those 2 x 4 blocks, well, the phrase needle in a haystack came to mind.

Off to Amazon we trotted to grab a few of the LEGO® Large Creative Brick Box kits (we would have preferred Lego.com for the loyalty points but we needed the Prime delivery) to top things up to 2000+ bricks per set.

Finally those three kits were done.

But we needed five, and even though there were a lot of bricks left in the marketplace stash, any kit we built from it wouldn’t match the the existing kits very well.

So we bit the bullet and ordered a bunch more from Lego.com.

Lots of boxed LEGO®

3 Stuffel bags, 8 LSP kits, 2 classic kits and a box of Duplo®

There are 11 boxes of bricks in that picture. That works out to only 2 LSP kit bags.

Of course I forgot that, tried to make 3 kit bags out of it and got very confused. And this does mean I do now have a spare Stuffel bag somewhere, which will be good for the day I need some quiet non-screen work and I have the energy and inclination to go through the remaining kilos of those 35kg.

Sorting LEGO® bricks can be very dull. Even the biggest brick fan would find the back pain and cramps hard to take after a while.

But it is rather satisfying when you get it all done.

And especially satisfying to say:

We have 7 fully specced LSP kits, ready to go for future workshop and conference use. Come talk to use about our bricks, because we’ve got thousands of them.
