I didn't grow up in Indiana. I've never lived in Indianapolis. But for 26 consecutive years, I've made the trip to the Indianapolis Motor Speedway for the greatest spectacle in racing. Twenty-six Memorial Day weekends. Twenty-six times hearing "Back Home Again in Indiana" while 300,000 people go quiet. Twenty-six times watching "Taps" echo across 2.5 miles of hallowed asphalt before the command to start engines.
The IMS Pagoda has been there for every single one of those visits. It was completed in 2000 — just before I started attending — and from the first time I saw it rising above the start/finish line, the building captivated me. Eleven stories of glass, steel, and purpose. Taller still when you count the flagpoles that crown its peak. It's not just a control tower. It's the nerve center of the most famous race in the world, and it's one of the most architecturally distinctive structures in all of sports.
At some point — probably during one of those long drives home on I-65 after the race — the idea took root. What if I built it? Not a simplified version. Not a display-friendly approximation. A real, architecturally accurate, museum-quality LEGO replica at a scale that captures the detail this building deserves.
I've built a lot of LEGO sets. Reviews on this site cover everything from Speed Champions to the Titanic to postcard builds. But there's a difference between following someone else's instructions and engineering something from scratch. This project is about the latter — deliberately choosing something that pushes past what I know how to do.
There's a therapeutic side to this too. After a day of work, I don't want to think about spreadsheets or deadlines. I want to sit down with a pile of bricks and a problem that has nothing to do with anything else in my life. The Pagoda build is that escape. It demands focus — real, sustained attention to measurements, proportions, and structural integrity — and in return it gives back the kind of quiet that only comes when your brain has fully committed to a single task.
Every brick placed in this model is, in some small way, a nod to the men and women that the Pagoda overlooks every May. That connection is not lost here.
The Pagoda also carries weight beyond architecture. The Indy 500 is held every Memorial Day weekend. "Taps" plays before every race. The Speedway served as a military facility in both World Wars. Building a scale replica of the structure that overlooks all of that history — there's something meaningful in the precision. Every floor plate placed correctly, every canopy overhang measured accurately, every staircase built to scale — it's a form of respect for what the building represents.
Isometric view of the Pagoda ground floor in Stud.io — the foundation that every upper floor builds from.
The scale anchor is simple: 1 LEGO stud equals approximately 1 real-world foot. At 1:38 scale, a standard LEGO minifigure stands about 4 bricks tall — roughly 4 feet in scale, which is slightly short for an adult but perfectly acceptable for context. With a hat or accessory, a minifig reaches about 5 bricks — close enough to a 5-foot person to sell the scene.
The build is designed as a modular building — not a modular city layout, but modular in the MOC sense. Each section of the Pagoda separates cleanly from the others for transport, photography, and display flexibility. You can lift a floor off, examine the interior detail, and set it back. This was a deliberate design choice from day one. An 11-story structure at this scale needs to come apart or it becomes a permanent, immovable display piece. I wanted both — museum-quality presence when assembled, and practical accessibility when working on individual levels.
One of the earliest and most important decisions was getting the car scale right. Most LEGO fans would reach for a Speed Champions car as a scale reference — but Speed Champions are 8-stud-wide builds. Do the math: at 1:38 scale, 8 studs equals 8 feet of real-world width. A real IndyCar is roughly 6.5 feet wide. A real pace car is about 6 feet wide. An 8-stud car sitting next to the Pagoda would look comically oversized — the building's proportions would read wrong immediately.
The answer was the LEGO City McLaren F1 #60442 — a 6-stud-wide car. Six studs equals 6 feet at scale. That's nearly perfect for a real car's width. Once I placed a 6-stud car next to the model, everything clicked. The Pagoda's proportions, the canopy overhangs, the bleacher section — they all made sense against a properly scaled vehicle. That single math check validated the entire scale decision and became the reference point for every measurement that followed.

The build features multiple setback floors — each upper level is slightly smaller and stepped back from the one below, creating the Pagoda's distinctive tapered profile. Cantilevered canopy overhangs extend approximately 10–12 studs from the building face. Angled facade elements capture the building's characteristic angular glass treatments. Bleacher seating, staircases, and a rooftop observation deck with railings complete the structure.
Here's what makes this project different from most MOCs: there are no floor plans for the IMS Pagoda available to the public. No architectural drawings. No CAD files. No cross-sections published in any book I've been able to find. Everything in this build has been reverse-engineered from photographs.
The elevator tower and bleacher section — one of the most structurally complex sub-assemblies in the build.
The process is methodical. For each floor of the Pagoda, I analyze multiple photographs to establish dimensions. I cross-reference against the 3D model. I calculate stud counts from real-world feet. Then I design the floor plate in Stud.io, verify every part number on BrickLink, and check that the structural connections actually work at this scale. Only then does a floor get approved for the build.
Some decisions are locked and final. The floor plate rule: largest plates on the perimeter, smallest toward the center. No 6×24 plates (cost-prohibitive at quantity) — always substitute with 6×16 plus 6×8 combinations. All staircases use uniform 2-plate rises. Rooftop railings use part #3185 — the Fence 1×4×2 Lattice in black. These rules keep the build consistent and the parts list practical.
Bleacher detail — individual seating, support structure, and railings at 1:38 scale.
Other decisions are still open. The canopy edge treatment — how to achieve that translucent, floating appearance at the tips of each overhang — remains the project's biggest unsolved design problem. Trans-clear curved slopes, light aqua pieces, bright light blue options — nothing perfectly replicates the real building's glass edge. That's the kind of problem that keeps me up at night. In a good way.
This is Part 1 of a 7-part build series. I'm documenting every design decision, dead end, and breakthrough — not just the finished product, but the thinking behind every brick. Here's where we're going:
Part 2: Modular Design — Why this build is modular (not a modular city — a modular building). How each floor separates for access, transport, and display. The engineering behind making an 11-story structure that comes apart cleanly and goes back together precisely.
Part 3: The Scale Math — The full breakdown of why Speed Champions 8-stud cars are too big for this build. How a 6-stud LEGO City car — the #60442 McLaren F1 — became the scale anchor. The math for minifigure height, car width, and how it all validates the 1:38 ratio.
Part 4: Ground Floor Footprint — The math behind establishing the Pagoda's base dimensions. How I measured the ground floor from photographs with no architectural drawings and translated pixel counts into stud counts.
Part 5: The Details — The level of detail I wanted to achieve and the compromises LEGO geometry forces. Canopy overhangs, angled facades, window treatments, bleacher seating, and the open design questions that are still being solved.
Part 6: The Reference Hunt — 150+ photos analyzed. Video sources including IMS's own Behind the Bricks series. How I screenshot specific scenes for angles you can't find in any still photograph. The process of building a reference library from nothing.
Part 7: Learning Stud.io — I learned BrickLink's Stud.io from scratch for this project. What worked, what didn't, and how the software shaped the design process. A practical guide for anyone picking up digital LEGO design for the first time.
Part 8: The Bulk Buy — My first time buying bulk LEGO on Facebook Marketplace. The thrill of the find, hauling home bags of unknown bricks, and then the deeply therapeutic process of sorting through thousands of pieces hunting for white and light gray — the two colors this build demands by the hundreds.
I haven't started fully building yet. The design phase is where this project lives right now — and honestly, that's where most of the interesting work happens. The physical build is the payoff, but the engineering is the journey.
If you've ever wanted to know what it takes to reverse-engineer a real building into LEGO from nothing but photographs and stubbornness — this is the series for you.
