My first Claude project ever (a floor-plan maker in one HTML file), completed in about 5-6 hours total

liwi808.itch.io/easy-blueprint-maker I've been using Claude to build a blueprint/floor-plan tool and thought the process was worth sharing. This is the first project I've actually finished with it. It's a single HTML file with a snap-to-grid canvas where you draw rooms, drop in furniture, and add doors. I originally wanted it to plan store layouts for a game idea, but could not find a free, easy program to use that had the features I wanted. I gave Claude a spec for the first version, it had something working in a few minutes, and I just kept building on it from there. Most of the time went into adding one feature at a time. Doors that stay attached to a wall when you resize the room. Merging two rooms into an L shape and being able to split them back apart. Undo, copy and paste, rotate. For each one I'd describe how I wanted it to behave, Claude would write the change and test it in a browser, and it usually caught its own bugs before showing me anything. When something still looked off I'd say what was wrong and it would fix it. The last stretch was cleanup and refinement. The sidebar had gotten cluttered, so we reorganized the layout, moved the canvas size and zoom controls into a top bar, and rewrote the help text to match. Total time to completion was about 5 to 6 hours of back and forth. It's still one file with no dependencies, and runs offline. I'm pretty proud of it. Please let me know what you think, and if you find any bugs. and I'm open to suggestions for what you would like to see added. Thank you!
