It's been a busy few days! The metal roof is on (but not yet weathered), the back wall is finished and the "tarpaper" (actually 320 sandpaper) is laid down. The wooden walkway is finished but won't be in place until after I weather it and the tarpaper. The skylight is so small that there was no metal thin enough for the details, so its mullions are painted on.
The front window is ready to be painted, but won't be installed until after the interior is finished.
At the request on my client, I also am going to build a planter box for a roof garden, which will be positioned between the back wall and the skylight.
There are also lots of small details still to be added to both the roof and the building.
