Lots of pieces to paint and assemble.
The interior panneling is 1/4" mahogony underlayment plywood. Cheaper than fir, and easier to finish. Everything is painted with Latex Enamel.
The drawers under the couch/bed are boxes on casters. The berth extension will sit on two of them. The desk has a roll-out box that has room for a printer and a computer tower, with storage for paper and disks. the desk top and counter tops are varnished 3/4" birch veneer plywood. The head counter has a sink that I removed from my travel trailer, and a lid over the bin for the peat moss for my composting toilet.
I also completed the front of the galley counter. It has a cutout for the stove, and drawer cutouts. the ice box will be at the aft end. You can see the helm seat that My Sister got at an auction for $6.00.
