Just want to make this design for a shed. Is this possible with the measurements. It is half brick construction and flat roof.

1. Will 100x50mm joists be good or do I need 145x50mm.
2. Which side should roof joists run. L-R or Front- Back.
3. Finally will the structure look ok given the measurements, or look crammed. Just want other's opinion on the design side.

Thanks all. View media item 81214

Run your joists on the shortest span (3metres) but you'll need the 145x50 to bridge a 3M span, unless you want a saggy roof. Why a flat roof, a peaked or single slope would solve a lot of drainage (and leakage) problems.

If you want a perspective view-point, make yourself a cardboard model and see what it looks like.

Love the drawing. You could give Tony a run for his money.

Thanks guys.

Noseall: Still not perfect like Tony's 😛 though.

Jack: By slope you mean (rear wall a bit higher than front ).I am restricted for height,ie,2.5 metre. I will be using some ferrings to achieve this. My footings are dug atm. I have gone down 800 and 300 wide.

What is the best material to use. Fibre roof or blow felt. I will be using OSB board. I suppose cant use tiles for such a low pitch, if i do decide to raise the rear wall for a slope roof.

Have you checked out the felt shingles. They come in about six colours and are in strips of about six "tiles" length. Very easy and starightforward to fix. They do need an underlay for maximum durability, on a OSB base.
They also have a minimum pitch at which they can be used.

They have something like a 10 year guarranteed life and they can be simply re-shingled over the top when it is required.

Ideal for EPDM.
