No worries. You can leave your shoes on.
Every day, we're passing many doors, we're walking through them, we're opening and closing them. Sometimes leave ajar. Sometimes leave them locked.
Thereby, we often see them as a plain means to an end. But if we stand still for a moment, we can see that a door can tell you countless stories without even entering a house. Knock Knock is a digital gallery of about 300 front doors. Enjoy the online stroll, play with the filters and get some inspiration by something as 'trivial' as a door.
