Unsure if my previous post worked..
Building a lean to off my shed and have a few concerns.
Fascia is 180x30 anchored to the shed and tied down into each pillar / concrete filled.
Joists are 90x35 with 600mm spacing.
Concerns are the ammount of joists hangers and the use of pryda 12g 35mm connector screws.
The job is not finished, any advice would be great. The idea for joist hangars was so i can have a ceiling and the roof will use staggered metal hats for fall.

Looking at the picture it looks like you have used 90mm there for the span, is that correct.
If you have, it is way under specced and you are going to have huge problems. It's simply doesn't meet code. Did you consult timber span and roofing codes?
What is the distance from the top to the bottom? It looks like it's over 4 metres.
Maybe I'm missing something but I think you may be in trouble if you proceed. I'd swear from the picture it already looks like it is sagging in the middle just holding its own weight.

Welcome to the forum
You will require Planning & Engineering designs/details and Certification for that
At a glance it is under Engineered...
I'd say Chippy's spot on it's sagging now and it will only get worse
Thanks for the photo

If that's is an Illegal non compliant structure you will have a much bigger issue than the screws used
Structurally it's not fit for purpose & Council will make you pull it down. hth

Any structure like your building needs council approval which will guarantee that the structural (and planning) side of the build is correct. It may seem like a pain but in the long run it's best.
Good on you for pulling it down and progressing correctly.
You were going to run into some serious issues if you went forward.

Good Move as It's not worth the hassle with Council
OT here is
1.The Councils Unauthorised and Building Compliant Department checks annual aerial photos
which Flags Illegal structures
2.They will inspect the unauthorised works and ask you for retrospective Planning and Building Approvals
3.The application also requires a certificate from an Engineer certifying the structure is fit for purpose
4.The Carpenter is long gone and won't be back to fix the issues
5.The council instigates legal action against the home owner
Goodluck with that...hth

Have you paid a fixed price for the slab? Keep an eye on the reinforcing, make sure it is per the drawings and has cover from the sides and bottom of the trenches.
