Well another weekend has seen some progress on Shedzilla, although I think next weekend is likely to be the last before putting the project to bed for the winter
On Saturday we managed to get the torch-on felt on the shed and garage - removing the old felt from the garage was a right royal pain in the bum as whoever put on the original felt omitted the underlay and bonded the first layer direct to the wooden roof boards - this meant that removal of the old felt took a lot longer than estimated GRR!

Still, an early start meant that we managed to complete the job by mid afternoon and still had time to get the guttering and drainage pipework in place
The drainage pipework was interesting as the original guttering on the rear of the garage had a downpipe that went straight into the ground and ran under the garden before joining the sewer system. I didn't fancy digging trenches to follow the run and reroute so I used a diamond core drill to take the pipework through the engineering brick wall (a slow and laborious process), and ran it under the floor to join the original pipework - luckily water doesn't need much of a fall as space was tight
All the pipework was sealed with internal beads of silicon and then left overnight to set - the bricks are there to keep everything in place while the silicon goes off. On Sunday, I tested with lots of water and no leaks - which was nice
Then it was a case of adding some additional joists and noggins to fill in the gap I'd left to make working on the pipework easier and fill the last gap in the first layer of the floor
Starting to get an idea of the internal space now even though only the back half has had its second layer of ply. At this point I ran out of ply so the rest of the floor is going to have to wait until next weekend - I just settled for adding a few scrap pieces as a temporary second layer over the pipework area as I don't want any flexing that could potentially disturb the pipes.
As I couldn't finish the floor, I decided to put in the doorstep - a single course of engineering bricks infilled with some nice strong concrete
Once the concrete had gone off enough, I topped the step with a nice, thick slab of mineral-rich slate - it's got lots of iron in which oxidises giving large golden-brown patches. It's hard to see the colours in the photo I acid-washed the slate a couple of times before using it and it's still wet from rinsing off the acid
Barring work-related emergencies, next weekend should see the floor finished and some large fluorescent lights installed - after that I've promised SWMBO that I'll ease off and leave the rest of the interior fit-out until after the winter (unless I get bored :evil: )
