The only clue is a lightbox at the street corner. Through the iron gate and a turn, you reach Knocknock. "Finding the door" is part of the experience. We saw the hidden value of this corner at first sight. Brick by brick, a ruin became a secret garden for cocktail lovers. Steps become seats; stone walls get wooden inserts as small tables. The partition wall pulls back to open up the garden; the bar counter moves forward, turning the windowsill into a bar table. The inside-outside boundary blurs through these pushes and pulls. The small garden extends the interior organically, adding usable seating and enriching the experience.
