I want to use it for when our granddaughters come to visit [we have a rustic log cabin for the guys] so want it to be feminine... maybe french country or cottage. A sleeper or daybed, futon, etc and tv with cabinetry for conceling my sewing supplies, ironing board and work/cutting table
Put bedroom at the front of this building and the workroom at the back. Figure 12x14 for bedroom and 12x10 for work area. Two small hand made platform beds could be made to form an L-shaped bed/sofa/room divider. The corner of which could be a table for lamp, etc. with backside facing into work area could be storage shelves. Hang the TV on the wall and put in a bench with stoage to use as a suitcase bench. A 36"x10' for a compact bathroom if you plan to install plumbing could also serve as part of a divider. Add a sink in the workarea if you do put in plumbing. Then buld in the work area as you please with open or covered shelves. Depending on how the room is laid out, a work surface at desired height could be built as the other part of room divider...with storage underneath. build cubby holes to suit! All this could be hand made and moveable...all except the bathroom and cabinets built on the back wall.
This a little bit bigger than our cabin: http://www.hometalk.com/531377/my-cabin aside from the "work" space do you have electricity, heat etc?I think row of cabinets for storage with some "work table" would be pretty easy to set up. Sleeping can be done with a futon couch...which can double as a hang out space.I our cabin we have a sleeping loft and a "dinning nook" that converts to a bed using some surplus cushion I got from a Salvage RV place.
What a fun space this will be Kate. I'd suggest searching CL for a used TV armoire to use for your sewing machine. I've seen one converted to a sewing center by adding a fold down table to put out your sewing machine. It's similar to a Murphy bed the way the table pulls down. Perfect for small spaces, or in your case, when you want to hide the machine when not in use.
