This was a pretty fun project. The Iowa room was built with a loft in it. The room wasn't especially suitable for a loft, but the owner of the house built a loft in each bedroom to create more space.
It was built by hand and there was a wooden latter, literally fashioned with 2x4s, that was used to get into the bed.
The room also has two giant windows in it and given Jordan's nightshift schedule, it was extremely difficult for her to get any good sleep in there during the day.
One evening I quickly drew up some plans one evening, purchased everything I needed at Home Depot, and got to work on a solution.
I had already ordered some blackout curtains and so I framed out the top of the loft in the same fashion one would frame out a wall. I ran the wiring into the bed area as necessary, complete with remote controlled switches, and then sealed it shut with the blackout curtains (having to cut them up rather significantly so they'd fit).
Finally, there was just a hole where the ladder was and this still let quite a bit of light bleed through. So I fashioned a trap door out of MDF, added a pulley and a counter-weight, and voila, the Treehouse was born.
It provided a wonderful, comfortable, and dark quarters for sleeping and I'm told helped Jordan's sleep rather significantly.
