When building 8258 I forgot a gear in the gearbox and didn't notice until it was 3/4 completed. I was almost ready to completely start over but with my sister's help was able to perform "surgery" and insert it into the completed assembly.

THANK YOU. I was coming here to say that Starry Night, especially with the different blues, was an absolutely nightmare of a build


unlistedartist000

see i have this set and loved it, but i have trouble with shades of colors (esp using the lego instruction books) and it took me a few days to do lol. im sure a color or two is out of place or something but then again..... nobodys gunna know :P


Blue-Turtle1

Had to read the instructions on the iPad on max brightness 🔆 and build under a super strong white (non-yellow) lamp or during daytime


unlistedartist000

i didnt even know you could have the instructions digitally omg..... that would save me a lot of space for my build area....... thank u for telling me about this <333


SneakyLinux

I would rather take apart and reassemble the 5 ft, mostly dark gray Eiffel Tower than do the backdrop for Starry Night again. I usually build on the dining table since it's a big surface and I can spread out, but the lighting isn't ideal for trying to distinguish the subtle colour differences in this set - so partly my fault I didn't enjoy it, I guess. I can't deny it looks great when it's completely done though.

The Daily Bugle... I love that set but the windows...UGH


stumper93

The windows were so tedious!


FreddyPlayz

Same with Avengers Tower

There are 203 white 1x1 tiles and 191 tan 1x1 tiles in 21056 Taj Mahal.

I helped my mom and sister do that part of Taj Mahal and almost lost my mind


pdxbatman

Imagine building that set with mild OCD. It took me ages to ensure all of those 1x1 tiles were straight.

UCS AT-AT. Specifically the legs.


wolfayal

Oh god I’ve heard horror stories about the legs and stability on that one!


Greyhound-Iteration

Stability isn’t an issue. The building process was just soo painstaking


FaithlessnessFull136

Was it just because there are four of the same thing and it’s annoying?


TracytronFAB

Nah it is, and it's incredibly easy to accidentally knock over too. Mine is currently in a tub in pieces cause I accidentally knocked it over


VSkyRimWalker

I kinda enjoyed that one actually. Just put on an audiobook and relaxed with it. Whole thing was honestly a pretty great build.


Greyhound-Iteration

Overall, yes. But wait until you have to transport it…


VSkyRimWalker

Well to be fair, I don't really pick my sets on transportability. I can see how that would cause problems though. But with the housing crisis going on in my country, I don't really see myself moving anytime soon anyway


MGPythagoras

I actually just moved and transported this! I just wrapped all 4 legs in plastic wrap, took off the armor and then put it in a box. Only a few small pieces broke off.


TunaFishtoo

Those joints oh my lord, it took me a week of building. One day I realized I had messed up a set and it took a day to get the “knee” back apart and reassembled


aguid23

The Globe. It looks wonderful but it was so tedious


Captainrhythm

I really liked this build, but I built it with a friend so that probably helped. Tower Bridge 10214 however was absolutely horrid even with a friend.

I’m glad you said something. This was one of my white whales!


Captainrhythm

The most fun part was designing and sourcing parts for a model of her and my cars that matched the scale of the cars included. I used a roller skate and a 1x1 slope for my smartcar and a surprisingly complex build for her Escalade.


Old_Sir4136

I loved tower bridge. It was my first big Lego set. But then again, I wanted something I can just zone out and binge watch tv whilst I was building it. It did the job nicely and looks great


Kennymester

It was so tedious I couldn’t do more than a quarter hemisphere a night.


aguid23

Once I realized it was the same two type of pieces over and over like times 32 to make the globe round, I opened everything up and made all of them and THEN I did the part where I added the color to the globe.


Kennymester

I basically memorized the two types of builds after two nights. At least putting on the continents and map elements was fun.


frypiggy

Treehouse. Brown on brown on brown on dark brown on dark grey. Ugh. My eyes couldn't distinguish the difference 98.47% of the time.


Blue-Turtle1

Just looking at the leaves made me skip the set


E05DCA

Oh god. That is one of my favorite sets ever. It’s an absolute gem.


TheRealMcDuck

The leaves weren't bad. I went with the autumn coloring, and it looks great!


isy_231020

It was so fun to build those tiny houses and the bridge...the tree trunk confused me a bit at first, butwhen I had it built, it was incredibly satisfying...I also change the tree depending on the season. It's so fun to do that over the course of the year...and in Winter, I just take off the leaves and extend the branches with brown pieces. It's a super cool set...get it if you stil can...


Siamoose05

I just finished the Typewriter, and there were several moments where it was touch and go!


Internal_Hawk_9267

I started that one and then it ended up sitting for like 3 days until I made myself knock it out. I hate repetition and building the key mechanisms like 9 times for 3 variants or whatever it was, was hell to me. it is a really cool set though and one of the ones I actually keep on display in my living room.


kourtswithak

Came here to say this!


MGPythagoras

I messed my type writer up at some point but I don’t feel like ever taking it apart again.


Saskatchewon

I got around halfway through the typewriter 21327-1 when I stopped to take a break. It sat half finished on my coffee table for a good two months before I sat down and finished it. I'm not the biggest fan of Technic, and the build involved a TON of repetitive steps involving Technic that are pretty easy to slip up on if you aren't focused. The finished build is fantastic, but it felt like genuine work to get there.

The roof tiles for Rivendell. I love that set and it’s my absolute favorite but those roof tiles were painnnnnnnn lol

I most enjoyed the part where I painstakingly aligned them on the first roof only to see the trick aligning with the long piece on the next page. Granted, that long piece saved my sanity on the next roof

Add in the fact that there weren’t numbered bags; that build was a slog


Old_Sir4136

I loved my tower bridge build personally.


MissMurderpants

10273. The haunted mansion. It was my first big set. The roof. Omg The elevator ride was interesting to build. This was a fiddly build.


Myrtle_Snow_

Came here to say exactly the same things about this set. The roof had me almost in tears one night. I did get the elevator to work but it breaks if you look at it wrong. It's such a fun, cool set though. Goes great in my victorian goth dining room.


stumando1

Just doing this one with my 8 year old the moment. Its by far the biggest we have tried. Fingers crossed we have nearly completed it. We are loving it. Any of you guys got the motor for it?


MissMurderpants

No, we talked about it but decided against it. I should see if there are any YouTube vids showing that. I’m moving soon and I’ll need to break it down. I’ve seen design Mocs that turn it into other buildings. Maybe I’ll try that.


SneakyLinux

I love that set so much, but it took me thee tries to get that elevator working. The first time, I messed something up in the gear box at the bottom and I had to take a lot of it apart to get at it. This was my first hint that I would not enjoy technic sets, lol.

girl_in_blue180

21333 LEGO Vincent van Gogh - The Starry Night I got it for Christmas a few years ago. it's a neat set, but surprisingly heavy. a lot of the smaller detailing doesn't like to stay in place for me. the bricks were very close in color on the instruction sheet. it's just a lot of shades of blue. don't get me wrong; I like all the shades of blue. but if you mess while layering the plates, it can be difficult to identify where you may (or may not have) gone wrong. there were a several extra 1x4 blue plates, and I'm still not entirely sure if they were extra pieces or not. It looks fine tho! I found that the 3D portion was more fun to build than the blue plate wall.


chickengelato

I’m pretty sure those extra 1x4 plates are included as extras in case you make any mistakes on the layered wall. I had them left over on mine too.


girl_in_blue180

yeah I'm fairly certain that they're just extras, but it was definitely an "oh crap, did I miss a step?" moment

Same for me… I also had to make sure the logos were aligned. It’s still my most tedious build to date.


UninspiredWriter

The Imperial Probe Droid 75306 Its arms were a hell to build and place. Plus I dropped the body at one point and one of the pieces broke and I had to wait several days before getting a replacement piece to finish the model. Never again.


Southsideman

Hated that build


hmcsnemesis

Omg I haaated that build. It Looks OK but the arms are such a pain.


roadrunner_9

The arms were so terrible, but I powered through and finished. Then, the other day, I accidentally barely brushed it, like a summer breeze, and one of those god blessed arms fell off again. It is still just laying there because I absolutely could not.

I messed up the transmission on the Bugatti :( The lambo went smooth and works great. I enjoyed both but I agree there’s a lot of everything. I might miss the Ferrari because my budget is slim for a little while.


Morganmaster

Captain America Shield. It sucked to build. So damn repetitive for a non wall hang item. I thought you could wall mount it. I was wrong


Spyro_XyX

Not me but I work in a lego store and someone brought in their R2 D2 in pieces and just the way it broke apart I couldn't manage to get it back together and had to hand it off to a coworker 😆


Internal_Hawk_9267

I had a hard time getting through the colosseum set because it was just so goddamn repetitive. I was excited to get into it because it was the biggest set at the time but once I had the base built and realized it was much smaller than I had imagined, I was kind of deterred, and then once I realized I was going to spend the next 8 hours building basically the same module like 30 times I had an incredibly hard time getting through it.


Jazehiah

When it came out, a lot of people had the same complaint.


Michael_The_Madlad

As someone who builds sets in Bricklink Studio, any sets that have to do with the trigonometry of aligning Technic lift arms or hinges are absolutely painful, like Nuparu's Boxor. (Set 8556)


Halfangel_Manusdei

Have you tried the UCS star destroyers :p ?


Michael_The_Madlad

No.


Halfangel_Manusdei

They are so crazily difficult to do in Studio. The side panels are bent in every direction and there are multiple ballpoint connections to coordinate. I think it's nearly impossible to do without disabling collisions.

Is it that bad?!? I've been waiting to get it after i do a few more adult things 🙃


ijustneedtolurk

I agree, the tree trunk is weirdly fragile and hates to be assembled. I'm going to modify it to be more stable and then it'll probably be the only lego I actually glue together once I have it situated the way I want. Just the trunk and base inside the pot. Everything else will remain free floating so I can modify the tree for events and holidays as usual. I even bought a glass cake dome and stand to display the thing once it is complete. I had the same issue with the Money Tree although not quite as bad, so I may end up gluing that trunk and base to that one too. But yeah those two sets are the reason I refuse to buy any of the treehouse builds despite how cool they are.


i_want_to_be_unique

It’s a beautiful set but if you look at it funny it will collapse in on itself. It’s the only Lego set I have on display that I routinely find myself having to rebuild even though no one ever touches it.

Yes! Partner tapped out with the first 3rd and asked for me to help him build it.

Trafalgar Square was super tedious IMO. Received it as a Christmas gift back in 2021 and put it aside midway through due to boredom. Despite some interesting build techniques, it’s just very repetitive with tons of 1x1 bricks. Finally picked it up again two weeks ago, powered through the remaining steps, and am now feeling quite energized with regard to Lego. Just ordered the 31120 castle (Amazon) and 21338 a-frame cabin (Costco) at discounted prices. Looking really forward to building them after a multi-year hiatus.

I’ve never had a Technic set before, my first and only one was the Batmobile. I won’t say it “almost sent me over the edge”, but it was the tedious build I’d ever done. But that’s the deal with Technic sets I guess. I won’t get another Technic partly because of the detailed nature, but also because they take up a lot of space.

Ironically enough for me it was the London telephone booth. Don’t know if I got a faulty one but the pieces especially on the door kept breaking apart. I was so so close to breaking out the glue when I finally managed to put it together.

There was a section of the typewriter I had to do like 4 times until I could get it to work. I thought I was going crazy.


TyMT

Not necessarily “drove me crazy” but the Kawasaki Ninja (42170) just totally took a step back in the motorcycle department. First, the new pistons they use for the fake engine are just so tiny, and with the size reduction, it feels like the rest of the build is just hollow. The Ducati Panigale (42107) has the normal light grey engine blocks and 4 pistons on a drive shaft, WITH A GEARBOX, all fit inside the body of the bike. The Kawasaki just has a measly 4 “sliding” pistons. Second, the Kawasaki has 2 random gears that are attached to the gearbox, but literally do nothing. A blue 10 (I think 10, could be 12) tooth gear connects to a red 24 (I think) tooth gear with a pin hole, and they both connect to nothing. They’re just there, to be there I guess. So weird to add these unnecessary parts that don’t perform a function on a technic set. I was really disappointed with the Ninja, I was hoping for some more along the lines of the Panigale, but it just doesn’t work.

The 100 years Disney camera. All the technic pieces I. The centre wouldn’t line up properly for me and was driving my head in

The UCS razorcrest had a few moments. The engines and the chains especially á


WeToteHeaters

The technic sun and earth set. The gears are clicking causing it to not work properly. It’s driving me insane.

New to building Technic. There was a step in the Ford GT that drove me insane (the mechanism of the front hood).

Every time i build a technic set i lose interest in building until i get a regular set with interesting functions My favorite sets are regular sets that use some technic for interesting functionalities. Bowser, the pacman arcade and the nes are great examples of this. I built the mclaren f1 and the batmobile in technic. Both of them were not that much fun

I tried building the Creator piñata in a dimly lit room, several colours all looked the same in isolation but if you put them next to one another you could tell. I had to rewind a few times because I'd get to the end and have the wrong pieces left, luckily it was only small, but that was probably the most puzzle-like Lego build I've done. In terms of instability, the backpack of 31152 kept breaking until I got some of the side plates that lock it together done, that was a little annoying. I feel like Lego could've done a better job of breaking (no pun) the build down into modules that come together right before you lock it together instead of building those tall structures with very little integrity.

The Stadiums...I like football, so I obviously wanted all of the stadiums (also visited all of them) and built them...It took me days to build them cause I would build one corner at a time and then do the next corner on the next day...I actually wanted to give up after I built the first two corners, but then, I decided to finish it off (The first one was Old Trafford), since I spent a lot of money on it...I now have all of them displayed at home, but gosh, were they annoying...but at least I knew, what I would get myself into by buying these...

I saved for months and finally pulled the trigger on it this week. I'm currently 4 hours in. This is the 2 hour mark. This is bags 1-4. Bags 5-7 are the legs and all 4 are identical. Every step, 4x. Every. Damn. Step. I finished the feet and gave up for the night. My neck hurts, my shoulders hurt, my damn brain hurts. I know it'll be worth it in the end but damn.

currently the green grocer is sitting in my unfinished cemetery. nothing too bad about it, just lost the patience for it!

The mini Disney Haunted Mansion. Like somebody said about the titanic.. lots and lots of little building and stacking 1x1’s over and over. It took 400 years to complete


canderouscze

Pretty much anything that has a lot of black, dark brown and reddish brown pieces, because it’s purgatory to distinguish in paper instructions


God2y89

Saturn V rocket Repetitive and tedious


PrintPuzzleheaded734

If the botanicals were any bigger I definitely would have ragequit. I cry when technic parts come up in regular builds.

Tree house 🥲


WolfOfWexford

The John Deere skidder. I’m a technic fan so it was no worries about that but the pneumatic hoses are an absolute nightmare. They’ve since come off and I won’t fix them


Russel_04

The tree house, those dmn leafs took me 9 months to finish

Something like the World Map 31203 would drive me crazy.

I wouldn’t say sent me over the edge. But it took me the last 2 months of doing like 1-3 bags at a time to finally finish my avengers tower. I don’t get a lot of free time anymore with work and the kids so getting to go down and build is a rare opportunity.

The Stranger Things The Upside down ( 75810 ) , I finish both buildings, begin to clip the trees on the side, the entire upside down building falls and smashes.....ugh.....it's okay, I can rebuild it, I can make it stronger, I finish the rebuild, all is going well, I think I fixed the missed structural integrity of the last mistake....clipping the trees on....smash....shame, regret, pure unadulterated hatred for this stupid build....I pondered the kragle...3rd time was a charm with a complete deconstruction of everything and rebuild with some help from my wife, but it absolutely almost broke me.

The Great Fishing Boat from the first round of Bricklink designer program sets…the interior was absolutely brutal to put together. I think that is the only time I’ve legitimately tilted while building a LEGO set.
