Too dark for photos today but :
So Far
Roof finished.
Walls Finished.
Exterior treated with stain/preservative to get rid of the green tinge from tanalising.
Both sliding door rails fitted and tested.
Oak face ply for interior walls purchased and cut to size.
This weekend (hopefully)
Door interiors paneled
Door exteriors clad
Doors hung
Wall next to the short door clad
Wall next to long door clad apart from where sparky needs to run the wires for sockets, although I might do that anyway just so I can get the wall finished.
That will leave two side of the shed finished, two to be plaster boarded and skimmed, the roof to be insulated, plaster boarded and skimmed and the sauna to be clad and wired up when the bits arrive from Estonia + the flooring to be sorted.
