How to Read Buildings
Like Duolingo, but for How to Read Buildings. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Decoding the Street View and Experiencing the Interior. It starts from scratch.

Key ideas in How to Read Buildings
- Gravity pulls overhead loads straight downward through connected structural parts
- Walls and columns transfer rooftop weight down into the foundation
- The foundation spreads the full weight of the building out onto solid bedrock or stable ground
- A horizontal beam transfers weight straight down into vertical posts to form flat openings
- An arch pushes downward weight diagonally outward, demanding heavy side walls or buttresses to keep from spreading
- External props and thick masonry are architectural cues that an arched ceiling is pushing outward
- Loose masonry like bricks cannot hang in mid-air over open space without collapsing downward
- A lintel beam or arch bridges the gap, carrying the heavy overhead wall around the open window
- The wider a window span is, the stronger the horizontal bridge or steeper the arch above it must be
- Internal steel and concrete skeletons carry the full weight of a modern skyscraper
- Exterior glass serves only as a weather barrier (a curtain wall) and carries zero structural load
- The most important public or entertainment rooms traditionally receive the tallest windows and richest exterior decoration
- Utility, servant, and private bedroom floors are signaled externally by smaller, plainer openings
- Façade ornament mirrors interior status rather than being distributed randomly across a building
- Repeating elements like columns, piers, and window openings establish a visual beat or rhythm
- Breaking a wide facade into repeating vertical segments prevents large buildings from overwhelming the street as a monolithic slab

Eight weeks. You meant to finish. You didn't.
Tomo gives How to Read Buildings the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
