I thought about what we already do to ventilate rooms & how that could be changed or improved. Opening windows stuck out the most. But what if we had the option of opening the walls & the roof as well as the windows? – What if the room could do all of this by itself? To follow up on this I looked around our home for some inspiration and eventually homed in on our wooden horizontal blinds and a set of long vertical fabric blinds that we have in our hallway. The blinds were doing exactly what I needed walls to be able to do. 

After realising this I searched the internet for different types of blinds & shutters, and after several searches, I landed on an image of some ventilation shutters which had been designed by the architect Le Corbusier –

and my vertical shutter wall idea was off.
