From LEGO to reality: building a climbing wall

Today, I thought to write about a little something different. It is not totally LEGO-related, but it started with LEGO, so I figured it would qualify for the topic of this blog. I was introduced to LEGO as a child by my dad. He is an architect, and he sometimes uses LEGO for modeling new architectural projects. (He also uses many other things, like clay, plastic, cardboard, wood, Styrofoam and – my favorite – chocolate). In fact, I knew LEGO as a modeling medium before I discovered that it was also a toy. With this upbringing, the concept of reaching for LEGO bricks when planning a new building project comes pretty naturally. 🙂

Many people use LEGO to replicate objects from real life that are already built; their house, car, school, church, place of work, and more. However, LEGO can also be used quite effectively when planning new projects. You don’t have to be an architect or designer to use LEGO as a modeling medium. LEGO can help anyone to visualize the size, shape, layout, colors and other details of a new project.

My new project was a climbing wall I wanted to build in our bedroom. I love indoor rock climbing, and our town used to have a really nice climbing gym. However, due to issues with the structural integrity of the building, after many years of accommodating a thriving climbing community, the gym had to be closed. The owners of the old gym have been looking for a new location, but the weeks of waiting turned into months, then years, and we still don’t have a climbing gym. There is a smaller location in a nearby town I sometimes go to, but due to the distance, I can’t make it that often.

Then, I discovered via YouTube that many people build their own climbing walls and bouldering caves, usually in their garage, some other empty space in their house, or even in their yard. I was immediately inspired by the idea and wanted to build my own climbing wall. However, we don’t have a garage, our ceilings are low, and our extreme weather conditions weren’t favorable either.

After looking at pictures and videos of other people’s climbing walls, I decided to choose our bedroom as the location of my wall, mostly because that’s the only unused larger space we had, and this way I could use our bed as a ready-made crashpad. I had enough room to put in a small climbing wall, a short horizontal peg-board, and a hang-board/small system wall.

And that’s where LEGO comes in to help with the planning stage of the project. I pulled out my LEGO bricks and built a replica of the bedroom, then started putting in the different elements of the climbing wall. As you can see on the picture, it is a pretty simple layout, but I have never built anything big like this, so working out the details with LEGO was helpful to wrap my brain around all the different steps that needed to be done. I even replicated the studs in the wall to remind myself that it is absolutely crucial to secure the climbing wall panels to the wall studs. I know this is very basic, but as I said, I was new to all of this.

Once I finished building the wall out of LEGO bricks, I was feeling more comfortable with the project and started to believe that I could, in fact, build it for real. The LEGO model was also useful for making a shopping list of all the building materials needed. It is basically three 4’x8′ sheets of plywood, plus some extra plywood for the peg-wall and hang-board. The plywood panels are attached to the studs in the wall by furring strips, leaving some empty space between the panels and the wall. This was necessary, so the different length bolts in the climbing holds have somewhere to go (instead of damaging the wall). Below is picture of how the wall looked like with two sheets of plywood installed, with the furring strips still exposed where the third sheet will go.

I’m not going to bore you with the details of building a climbing wall on a LEGO blog, but just briefly, here are the steps I followed: 1.) plan layout of the wall 2.) make a shopping list and purchase necessary materials and tools 3.) find studs in the wall using a stud-finder or strong magnet (I used both to make sure) 4.) cut to size and attach 2″x4″ furring strips to the studs in the wall using decking screws 5.) cut to size plywood sheets, drill holes for t-nuts, sand and paint plywood sheets, install t-nuts 6.) attach plywood sheets to furring strips using decking screws 7.) purchase or make climbing holds and attach them to the climbing wall (I got mostly bolt-on holds so I can regularly reconfigure my wall, and also a few screw on holds). 8.) climb!!!

You may have noticed that in the LEGO model of the climbing wall I used tan for the bottom of the wall and white for the upper section. I was originally planning to texture the wall with outdoor deck paint, and those were my choices for color. However, once I saw how nice the plywood sheets looked, I decided to just finish them with several layers of polyurethane coating. Having some parts of the plan change as you work on your project is quite natural. I did stay with white and tan climbing holds though.

All in all, the climbing wall turned out as planned in the original LEGO model, and I have been really happy with it. I particularly like the peg-board and hang-board section, and those big holds with cracks on the climbing wall section. I didn’t have any hiccups in building the project, but I kept it pretty simple. As you can see, I didn’t add any angled walls or roof climbing. This is mostly because our house is old, and I wasn’t sure about the condition of the wall studs. I didn’t want to put any additional stress on them. With my skill level, this layout should keep me busy for a while. Now I climb every morning when I wake up, and also throughout the day.

I can definitely say that building the climbing wall first out of LEGO really helped both in planning, and mentally accepting the idea that I can do it. I should add that before this project, my only experience using power tools and building something big was cutting and attaching plywood to cover our windows before a couple of approaching hurricanes. Other helpful tools were some YouTube tutorials about building a climbing wall, particularly this video and this. I have also downloaded a number of free PDF instructions for building the wall, but the one I ended up using was this one from Atomik Climbing Holds. This is also the company where I purchased all my climbing holds, as well as t-nuts, and bolts for attaching the holds.

The kitten you see helping me during the building process is Hiss & Bite. She is a feral kitty left at our place by her mom before hurricane Irma hit our area. Mom never returned, and Hiss & Bite lived through the hurricane hiding out at our carport. During those rough times, and later building the wall together, we became friends. Now she is supervising everything I do…

If you would like to use LEGO for modeling, there are a couple of suggestions that I could offer. One is that if you are planning something for your living space, get away from trying to make it minifig-scale. Minifigs are not realistic representation of humans, so everything in minifig-world is off-scale. Notice that I did not use a regular LEGO door in the doorframe. This is because LEGO doors are not in-scale with real doors. It is better to convert LEGO studs to feet (or meter) instead, and just scale down the space you are working with from real life. My second suggestion would be to stay with neutral, realistic colors, or even just one soft color. This helps with not getting distracted by the bright colors of LEGO during the planning/designing stage. I lucked out, as I had some light-yellow pieces that are the exact same color as the bedroom wall, and I also had all the white and tan pieces I needed. But I could have also made the model with similar soft colors and could have still visualized the project pretty well.

If you don’t have any basic pieces in soft, neutral colors, the #21050 LEGO Architecture Studio set is excellent for starting out with LEGO modeling. It comes with 1211 mostly white and some clear pieces, and even includes a hefty book teaching basic concepts of architecture, design, and modeling with LEGO. You can find it under the LEGO Architecture section of the Online LEGO Shop and on

I hope you found this little detour from our regular LEGO news and reviews a bit interesting and informational. What do you think? Have you ever used LEGO for either modeling objects from real life, or planning projects that you were working on? What was your experience? Are there any tips and tricks you would like to add?

Wait. You built what?? This is amazing! Love the whole story! Now I want to build a climbing wall!


admin December 29, 2017 at 11:39 AM

LOL! Go for it! 😀


Tony December 29, 2017 at 10:27 AM

Wow! Girl, that’s awesome! Question; so the gap is only required if you are using bolts for the climbing holds? If you screw them all on, you could attach the panels directly to the wall?


admin December 29, 2017 at 11:42 AM

Yes, that is correct. If you are using screw-on holds, and you make sure that the screws are not longer than the width of the holds and the panel, thank you can attach the 4×8 plywood sheets directly to the wall. Just makes sure they are securely attached to the wall studs behind the drywall. However, because my wall is small, and I wanted to make it as versatile as possible, bolt-on holds were a better choice.

Where did you get that articulated minifig? I want one, but it doesn’t look like lego. And I want your wall too! looks fun!


Håkan December 29, 2017 at 10:32 AM

Yeah. I was just wondering about that.

By the way, the wall looks nice, but I’d need any available wall space I’ve got for bookshelves… =/


admin December 29, 2017 at 11:45 AM

Bookshelves make great climbing walls… just sayin’… 🙄


admin December 29, 2017 at 11:43 AM

The articulated minifigs is from Minifigs.Cat. I really like it:


Håkan December 29, 2017 at 11:59 AM

A Chinese Si-Dan product, it seems. Looks pretty good, at least…


admin December 29, 2017 at 12:03 PM

I have lots of stuff from them, and they are definitely very good quality. I have reviewed their products a number of times. And I really like the articulated minifigs. 🙂


Hayato December 29, 2017 at 10:34 AM

I hope my kids don’t see this…. seriously, really cool! This gives me an idea of having the kids build their dream room out of lego. See what they come up with.


admin December 29, 2017 at 11:55 AM

That’s actually a great idea! It allows you to talk through new projects in a creative and visual way. 🙂


Håkan December 29, 2017 at 10:35 AM

Would be a good idea to keep the cat away from the glue… No need for more hissing and biting than necessary…


admin December 29, 2017 at 11:57 AM

LOL! She is not hissing and biting as much any more. But she was very hissy when she was little. She was very scared of people. She is still scared of strangers, but that’s normal for feral cats. I estimate that she is about 6 months old now. 🙂


brickmaster December 29, 2017 at 10:42 AM

You have Lego and you have a climbing wall. Can I come over to your house? It’s more fun than my space! As far as your question, I once try to replicate my grandparents’ house out of Lego. Once you start building, it quickly becomes apparent that minifig scale doesn’t equal people scale.


Håkan December 29, 2017 at 11:42 AM

Minifig scale is a complicated matter.

(The Microfig height is stated incorrectly, though.)


admin December 29, 2017 at 12:04 PM

Tom Alphin is a master of using LEGO for architectural projects and that’s a great reference. 🙂


admin December 29, 2017 at 11:58 AM

Sure come on over! 😀

Yeah, it takes a while to figure out how to work with LEGO when you want something realistically scaled.


Mav.Weirdo December 30, 2017 at 12:23 AM

I did a microbuild of my grandparents house for the “mini building madness” contest.

FrenchToast December 29, 2017 at 10:54 AM

Okay, I know what our New Year project is going to be! Very cool!


admin December 29, 2017 at 12:00 PM

It’s definitely a fun project, so go for it! 😀


SPMom December 29, 2017 at 11:27 AM

My son would love this! I don’t know if I’m brave enough to build something big like this, but I like the idea of using legos for planning. I may use that next time we redecorate any part of the house. Really like your wall, and thanks for sharing the touching story about your kitty friend.


admin December 29, 2017 at 12:02 PM

Glad you liked the story. We have so much wildlife here, we always have someone stop by for shelter. Some become friends, some move on… as far as building the wall, I wasn’t feeling very brave either, but by watching the videos, studying the plans, working out the details, and talking a lot with my “supervisor”, it started to sound doable. The way to eat an elephant is one step at a time. 😉


jabber-baby-wocky December 29, 2017 at 1:14 PM

Very very cool. Climbing is a great workout. I was reading that on American Ninja Warrior most of the best contestants have a climbing background.


admin December 29, 2017 at 2:10 PM

Yes, that’s true. There are actually a couple of Ninja Warrior contestants in my town. They train in rock climbing, martial arts, aerial dance, and more. Climbing is definitely an excellent whole body workout, and it’s a lot more fun than spending time on all those weird machines at the gym that look like torture devices. 😀


gid617 December 29, 2017 at 1:47 PM

Mostly I’m just amazed at the idea of building a rock-climbing wall in your bedroom, but using LEGO to design it is definitely cool too. 😉

Do you know I think I want one now. 😛 Actually I’ve only climbed on those kinda things a couple times in my life. Once it was high enough to need a cord system (or whatever that should be called), but for the most part just as a big kid on playgrounds here and there where I could practically jump and land on the top. hehe I’d love to do some real rock climbing one day though!


admin December 29, 2017 at 2:06 PM

Rock climbing is awesome. I first got introduced to it when we went on a cruise some years back. It had a great climbing wall, the kind you mentioned; tall, with ropes. Then, I discovered that we had a great climbing gym in our town, but as I mentioned in the post, it was closed down.

When I was going to the climbing gym, I learned that there are all kinds of climbing methods. There is climbing of high walls, called top-rope climbing, where you will either need a partner to hold your rope, or use autobelay, but there is also bouldering, cave climbing, campus-board, moon-board, system-wall, peg-wall climbing and more. While most people won’t have high enough ceilings to build a tall climbing wall, you can do definitely build a wall for the other activities. They are just as challenging, but they don’t require a high wall. Even just putting a small hang-board or system-system wall above your door gives you plenty of challenging workouts.

Also, while I bought my climbing holds, you can also make your own, making the project even cheaper. There are tons of videos on YouTube on how to build various climbing related equipment.

Climbing is a great whole body workout that is becoming more and more popular. When I was in Vancouver earlier this year, they had a climbing gym at practically every corner. They even had one in a converted silo! 😀


gid617 December 30, 2017 at 7:26 PM

Well I had no idea climbing was so big! It does sound like a great way to exercise a bunch of random muscles all over the place. Now I shall better value my opportunity next time I get a chance to climb a rock wall. 😉


admin December 31, 2017 at 11:36 AM

Have fun! 😀


TomTom December 29, 2017 at 3:02 PM

This is a great project and I’m very impressed. Nice to see Lego fans being involved in challenging sports. A lot of my Lego friends are indoors people sitting in front of their computers, then build some Lego, then sit in front of their computers again.


admin December 29, 2017 at 3:51 PM

LEGO fans are just like people in many other hobbies; there is a great variety. While it is true that many of them live sedentary lives, there are also others who are greatly into sports. I know Jason Allemann (JK Brickworks) is a very serious climber, there are others who are into martial arts, biking, hiking, watersports and more. We are a mixed bunch. 😉


JasonK December 29, 2017 at 4:42 PM

Very cool. What are those dangly gold pieces over the door in the lego model?


JasonK December 29, 2017 at 4:49 PM

Oh, and also the gold pegs the little dude is using in the pegwall. Are those lego?


Håkan December 30, 2017 at 5:39 AM

That’s a weird part. Could it be metal?


admin December 30, 2017 at 9:01 AM

It’s ABS plastic. A small vial from BrickForge. I have a bunch of them in different colors as they are very useful little rods with a stopper at one end. 🙂


Håkan December 30, 2017 at 10:09 AM

Ah, it was a typo for vial. I got confused, so it took me a while to find it.


admin December 30, 2017 at 11:00 AM

Yes, that’s it. Sorry about the typo. 😀

My family use to move a lot and when I was little my Dad would use the moving boxes and make them into forts or castles. I had a blast . The imagination was running wild . The left over pieces of cardboard would become swords and Shields. So, my weren’t the most wealthiest families . We had our struggles. That meant that my toy collection wasn’t very big . So , I use to use shoe boxes or something of that size maybe bigger. I turn them into castle or fortress for my action figures . In fact I made a Jabba the hutt’s palace out of cardboard( complete with a trap door). That’s where my creativity comes from. To this day I still make things from scratch only they are out of Lego bricks.


admin December 30, 2017 at 9:04 AM

Oh, yes! Cardboard forts are awesome! 😀


Håkan December 30, 2017 at 9:58 AM

I did Styrofoam space bases for my Futuron astronauts… We’d bought a Stereo or something with rounded walls, so the Styrofoam had pretty rounded shapes…


admin December 30, 2017 at 11:02 AM

Gosh, I used to love those Styrofoam boxes! Some had really interesting shapes that made perfect space stations, or spaceship interiors, and a host of other things. We also used to use one for a Hoth base. 😀


Mav.Weirdo December 30, 2017 at 12:28 AM

When we were having the bathroom renovated I used Lego bricks to try out some tile patterns for the shower wall.


admin December 30, 2017 at 9:02 AM

Oh, yes! That’s a great application! 😀
