The SOS Forums had this interesting thread about a bloke who can turn his guest room into a studio in about 10 minutes.
My studio set up consists of a control room/office which is unusual in that it has no parallel surfaces, even a sloping roof. This room is loosely triangular being a maximum of 4.8m long and 4.5m deep. There’s a short 1.2m corridor (which I call the portal) that leads into a guest bedroom which is 3m by 2.7m.
Sometime ago I renovated the guest room so that I can convert it into a studio in around 10 minutes and I thought this might be interesting/useful.
The guest bedroom has a permanently installed double bed in it, but I’ve put it on hinges! It’s really easy to hinge the bed onto the wall
