I want to make houses like this. This is totally rad. A family commissions an architect to renovate the interior of their home, and gives him some vague suggestion to make it 'playful,' and hide a poem written by the previous owner somewhere in the house 'like a message in a bottle,' and said architect then spends four years turning their house into a walk-in game of Myst, with encrypted poetry written on the radiators and tiny scale models of rooms hidden behind panels in the walls, and storybooks full of clues commissioned specifically to be written for the house.
