Another few evenings spent in the ceiling and the end is in sight.
Over the last few days the shelves were finished. The railing around the ladder hole is done, and the air vents are in place.
Tonight I finished off the final part of the door frames, cleaned out all the offcuts of wood and removed all the tools. Now all that is left is to clean everything and give the walls a coat of sealant and the floor a coat of varnish. That should protect everything a bit and stop it getting so dirty. Then we can start moving the junk there.
