THE Ramapo is the flagship of our free plan series. This is a 3 plywood large building made as square as possible without any extra fanciful saw work. This originally started out as a sketch for a bunkhouse on a rural property. The square walls, simple roofline, and single windowed facade make for a quick frame-up. If you learned on Tuesday that the in-laws were coming you could erect this little mansion in time for their Friday arrival.
The original intention was to place a 38" twin size bunkbed to the left and a 54" full size bed on the right. By shifting the door about 2' left you could have room for a queen mattress and floor space to tango. The other option is to squeeze in a small powder room to the right of the door, possibly with a lofted bed above. The possibilities here are endless and only limited by the mount of warning you have to build.
Most jurisdictions should not require a building permit for such a small structure. However you may want to inquire as to whether a zoning permit is necessary. As always, obey setbacks and don't irritate your neighbors.
