A developer sells the same flat three times: as a number in a catalogue, as a plan in a building, and as a document you sign. The site had to hold all three without making the visitor learn a new interface each time.

The catalogue carries three views of the same stock: grid, list and the chessboard developers actually think in. A buyer and a sales manager can look at the same page and each see what they came for. Every state is drawn: empty results, request modals, success and error.
