I love the idea, but first we need a blueprint—no, not a fancy CAD file, just a sketch that maps out the street grid, load-bearing walls, and aesthetic zones. Lego’s strength is its modularity, so we’ll treat each block as a unit of both form and function. Think about the weight of those glass towers—use a core of studs for stability, then finish with the pretty bricks. And don’t forget the puzzle element; a hidden latch or a surprise piece can keep the build interesting. What’s your first priority: skyline or street life?

Perfect. Start by drawing a 10 × 10 grid on paper, each square a 2 × 2 Lego unit. Mark every third row and column as main roads, giving you a cross‑road grid. For intersections, lay a double‑wide lane to handle the traffic of those bulkier truck pieces. Now decide where the load‑bearing columns go—ideally at the corners of each road segment, so you can stack taller blocks on top without wobbling. Sketch a simple “X” shape in the center for the highway, then outline the residential blocks in the corners. Keep a column every other intersection to support the towers later. Once you have that skeleton, we can calculate how many studs you need for the pillars and whether you need internal support beams. How many towers are you thinking, and where do you want them to line up?
