The toughest piece here is clearly the 3D apartment model itself, and the maker attacked it with real preparation: blueprints, Sweet Home 3D plans, photos of every room, lamp lists, descriptions and structured requests. Claude reportedly said that with that level of detail a single prompt alone would never get there, which matches the polish in the result. The look came together through Sweet Home 3D, Photoshop, Blender, Claude and, in the maker's own words, a lot of time.
What stands out is how live everything is. The apartment model rotates freely, and individual lamp color gradients update the virtual room lighting in real time, covering Hue gradient gear like Signe floor lamps and TV backlight strips. Movie scenes light up a virtual television screen, there is a toggle between a dark nighttime mode and a bright daytime view, and the vacuum named Margrit reports battery status and cleaning routes. Climate controls and live power monitors round it out, with wattage readings from 202 to 344 W and temperatures between 17.5 and 24.4 degrees.
The setup behind it is tidy too: Home Assistant runs on UTM on a Mac mini, the maker is really happy with that, and the dashboard reportedly runs smoothly on an iPad and an iPhone. The display is a 13 inch iPad Pro.
Two things remain open. The rendered pet image is called far from perfect, though good enough for a laugh, with refinement planned for next week. And no written guide exists yet, so anyone wanting to copy this still has to ask.
