We have a spare bedroom that is long, but also fairly narrow. With a queen bed there wasn't much space for anything else, but we wanted to make the room more multi-functional. The obvious solution was a murphy bed.
We spoke to some of the local suppliers, and for a basic murphy bed and cabinet with no additional storage space the price would have been about $3,500. That's a little steep, but the bigger problem is that we didn't like the style of any of them.
I'd seen two ikea hacks that used Pax cabinets with a murphy bed kit:http://jerrystarbuckproject.blogspot.ca/2011/02/murphy-bed-with-ikea-cabinets.htmlhttp://herbiesworld.blogspot.ca/2009/04/guest-room-remodel-budget-murphy-bed.html
Neither of those were what we were looking for either, but they inspired me to try something similar with some tweaks.
