Tetris.Casa

Problem solved

Sketching a floor plan to scale is either pen-on-paper or a heavy CAD suite. Homeowners planning a renovation, a move, or a new build have no lightweight, playful tool that snaps to a grid and respects real dimensions.

Value proposition

Drop rooms like tetrominoes, snap to the grid, rotate, multi-select, and preview the result in isometric 3D. Plans save to your browser and export as JSON. Works offline, runs in every modern browser.

Target Audience

Homeowners planning renovations, first-time buyers visualizing a layout, architects who want a quick-sketch tool, and anyone who enjoys a game-like drawing interface.
