#21067 Tower Bridge is $350 for 3745 pieces.

First Impressions

Before the set arrived in the mail, I had just heard rumors of the price and part count. I immediately thought of two previous LEGO sets, because I predicted that it combines aspects of both. Naturally, the first comparison is #10214 Tower Bridge (2010), a long-retired set with a comparable 4287 pieces and a delightful $240 price tag. It was an early entrant in the ‘landmarks’ collection within what became the Creator Expert lineup. Buildings in this series were all about size, and often less detailed than sets in the LEGO Architecture lineup.

The other set that jumped to mind was the recent #21061 Notre Dame (2024) set. It’s a modern set in the LEGO Architecture series with a comparable 4383 pieces, but with an excellent $230 price tag. It is surprisingly compact despite the high part count, thanks to tons of intricate details made from lots of small parts. (It earned a rare 5/5 Star rating in our review.)

My expectation for this set is something larger than Notre Dame, but smaller and more intricate than the 2010 version of Tower Bridge. I worry that both of these comparisons will make it feel like a poor value, since it is likely smaller and more expensive than #10214 Tower Bridge, and a lot more expensive than #21061 Notre Dame for a similar price point.

When I saw the box for the first time, I immediately noticed the vibrant colors which are more striking than the original model. I was a bit surprised to see that the scale is much closer to the original than I predicted, likely only a few studs narrower due to more realistic proportions for the two tower sections. The price still seems a bit high, but my first impression was more favorable than I worried.

Build Process

Upon opening the box, you will discover 25 numbered bags, three un-numbered clear bags, and a large instruction booklet in a paper pouch. This feels like a more impressive project after opening the box, since the box isn’t all that huge.

The set contains 25 numbered bags.

Since the model is largely symmetrical, it is no surprise that the first 8 bags build one side of the model, and bags 9-16 build the other side. We connect the two sides in bags 17-18, and we will finish the towers and suspension cables in the last seven bags.

The instruction booklet explains the main stages of the build process.

Bags 1-8 & 9-16: Water and Road Surface

We learn on the next page that both sides of the model are identical, so I went ahead and built them both at the same time. Starting with Bag 1, we create a simple platform out of plates and tiles which will be familiar to LEGO Architecture fans. The 42Transparent Light BlueTrans-Light Blue tiles look a lot darker since they are placed on a 26Black base. I was able to build the second copy only slightly faster than the first one.

In the second bag, we build the towers up, with rounded corners using a stack of 4×4 Ø8 Round Corner Brick (Large Macaroni) (Part 48092) on all four corners. In the middle, a Technic assembly is installed with a pair of Technic Beams sticking up on both sides.

A pair of Technic beams are hidden inside the tower base.

The road deck is added in Bag 3 using 23Bright BlueBlue with 1White railings. The road surface has several exposed studs, where I anticipate we will attach cars and buses later.

the road section is assembled as one large piece.

The fourth bag introduces a play feature in the form of a working drawbridge. We spend most of the time building the road deck, and a pair of triangular supports on the underside. The supports look nice, lending a believable structural engineering nod to the overall design. The bridge rotates on a pair of Click Sockets: 1×2 Brick w/ Click Pin (Part 4920) is embedded in the tower structure and 1×2×1⅓ Rotation Joint (Part 80431) is integrated into the road deck.

Getting ready to install the drawbridge assembly.

As will be explained in my upcoming book The LEGO Parts Guide, Click Sockets are a strong articulated connection that can be positioned in 15° increments (since there are six teeth per 90° of rotation).

Bag 5 is pretty quick, since we only increase the height of the tower by a small amount. We also strengthen the area holding the click socket in place by adding additional plates on top, and adding a vertical component that prevents you from raising the drawbridge too high and breaking the model. (I learned this the hard way when my son opened the drawbridge all the way after the fourth bag, and it fell off.)

We encounter additional architectural techniques in the sixth bag, including ornate friezes along the top edge built using clips, rails, and 1×2 3-Teeth, Horizontal (Part 15208). This is also where we see three different printed elements for the first time, a 5Brick YellowTan 1×1 Tile with one arched window, a 5Brick YellowTan 1×2 Tile with one tall arched window, and a 1White 1×2 Tile with one tall arched window.

Inverted arch and window assemblies.

We first saw the use of printed tiles for windows in the LEGO Architecture series in #21063 Neuschwanstein Castle. I did not like how it looked when that set was released, and I don’t really like how it looks here either. The raised tiles are a little less noticeable here, since they are set into a recessed area between the rounded corners.

Bag 7 is pretty straightforward — we simply continue building the tower even taller. Again, it relies on printed tiles, including two additional 2×2 tile variants, one with three bays of windows, and one with four. Bag 8 is largely the same, adding another bay of windows on all four sides.

Two identical bridge halves at the ends of bags 8 and 16 respectively.

Bags 9-16 repeat the process exactly, since we build two exact copies before attaching them in the next stage.

Build time: 153 minutes (Bags 1+9: 16:20, Bags 2+10: 16:00, Bags 3+11: 15:40, Bags 4+12: 24:40, Bags 5+13: 16:35, Bags 6+14: 24:10, Bags 7+15: 20:20, Bags 8+16: 19:00.)

Bags 17-18: Connection

While it was common to open multiple bags in the past, this is pretty rare in modern sets. Nonetheless, you will need to open both Bags 17 & 18 to build the next stage of the model. There’s nothing all that surprising about this section: the plates connecting the bases are completely predictable.

Sub-assemblies added in Bags 17-18.

Looking higher, we have two raised bridge assemblies which rely on the same fence element used in the earlier 2010 set. In fact, 1×4×2 Fence, Lattice (Part 3185) was introduced in 1967 (59 years ago).

Progress at the end of Bag 18.

Build Time: 18 minutes

Bags 19-35: Completion

In Bag 19, we work on the left side of the bridge by building the tower around the raised walkways we built in the previous stage. There is some nice exterior detailing including the use of 1×2 Gold Bar (Part 99563) for rusticated stonework.

Reinforcing the tower connections in Bag 19.

In Bag 20, we just build rectangular columns for all four corners of the top of the tower. This seems straightforward enough, except each of the four towers are dense SNOT assemblies and are a little different. This took longer to build than any other bag so far.

Adding squared-off corners for the top section of the tower.

Bag 21 completes the first tower. The focus here is on a final bay of windows on all four sides, built into the gables of the sloping 151Sand Green roof. The effect is finished with white spires on the four corners, and a row of 297Warm GoldPearl Gold spires along the top edge. This was a satisfying bag, bringing nice detailing and closure to the first tower.

Bags 22-24 repeat the process, but for the other tower. You can decide if you want to alternate between the towers or build each tower separately.

We wrap things up in Bag 25, which is a quick finale to this substantial project. First, we build a bunch of cars, mostly involving a 1×1 Tile attached to a 1×2 Jumper. There’s also a classic double-decker bus, strategically placed near the middle of the model. Finally, we add the suspension cables, each involving a pair of 16L Flex Axle (Part 32202) connected using a Technic 3L Axle Connector (Part 42195).

Adding some cars and an iconic double-decker bus in the final bag.

Build time: 84 minutes (Bag 19: 8:35, Bag 20: 18:45, Bag 21: 11:20, Bag 22: 8:15, Bag 23: 15:50, Bag 24: 11:25, Bag 25: 10:00.)

Value

While expensive, this is a physically large model which will require some space to display it properly. In fact, it is just shy of 1 yard (35.25″) which works out to 89.5 cm. If you want to display it with some space on either side, you will need a spot that’s a full meter wide! With a total build time of 255 minutes (4:15), this is neither an extremely long build, nor something you probably want to build in a single sitting. It’s also fairly heavy at 2.5 kg (5.5 pounds).

Price-per-gram gives us an objective measure of value, and it tells us that this set offers an unusually poor value. And this table includes many licensed sets containing rare minifigures, which can skew a set’s price higher.

Conclusion

My expectations before the set arrived were modest, improved slightly when I saw the bright colors and fine details reflected in the box art, held largely steady as I built the model, and fell back down once I realized the extremely poor value based on the price-per-gram and price-per-minute metrics. This set doesn’t just feel overpriced, it is overpriced and the data backs it up.

The upside, and it is a big upside, is that this is a nice looking model and it was pleasant to build. If you are looking for a large and impressive display model, and you can find this set for a discount of 15% or more, I am happy to recommend it. While largely a static model, it is nice to have a tiny bit of ‘play features’ in this set since the drawbridge goes up and down — just don’t forget to remove the vehicles from the central span when the bridge is raised, or it will look like a re-enactment from Grand Theft Auto or The Fast and the Furious films.

#21067 Tower Bridge – Completed Model.

When it comes to parts and building techniques, there are a few things worth noting. While I already expressed my disdain for relying on printed parts to represent windows, this set is a great source of printed tiles representing slender windows with an arched top. They might be useful for a MOC you are trying to build. The set also teaches why the larger Click Sockets exist — unlike click hinges, they are able to hold a heavy bridge assembly at an angle.

Lastly, there are some good examples of intricate SNOT techiques used throughout the towers. Notice how the 1/2 plate difference between the height and width of a LEGO brick is sometimes resolved by attaching something 2 studs wide (5 plates tall), and other times it is ignored by having the SNOT section extend beyond the rest of the wall.

#21067 Tower Bridge – As viewed from the front.

I personally preferred when the LEGO Architecture series focused on microscale models, and was separate from the Creator Expert Landmark series which explored larger models; this set would have fit nicely into the Creator Expert lineup due to its large size. That said, #21067 Tower Bridge is a perfectly acceptable set in a series containing excellent re-creations of Architecture models.

Due to the atrocious value, it is bumped down to a Good (3/5 star) rating from the 4/5 star rating it likely would have earned with a more appropriate $300 price tag. (I rarely penalize sets so blatantly based on the price, but this is an extremely bad example.)
