MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Well, theres hasn't been one on the front page for at least 46 minutes so time for another...
After an impulse buy of a log cabin/shed on eBay last week I could do with a few pointers from you experienced folk.
I've got a concrete pad already so my plan was to build a frame, lay that on blocks to keep it slightly off the pad. Insulate the frame, OSB boards on top of that then build the shed on top of that. Does that make sense?
2 questions:
- For the frame, is 3x2 with 400/450mm centres ok or would 4x2 with say 600mm centres make more sense?
- Would you put some waterproof membrane between the frame/boards or boards/shed floor or not at all?
Hopefully photos to follow this week.
I put DPC membrane under the bearers on mine
How do you stop water collecting in the DPC if it is under the bearers?
Thinking it's probably sensible to go with 4x2 and 450mm centres for the sake of a few extra quid.
Off to get the bricks and timber today and making a start at the weekend.
Based on the sticking a DPC under and how to stop pooling I used treated fenceposts for the frame.
I painted bitumen on the underside and stuck the whole lot on open concrete block above the concrete base. This raises the entrance by 6" or so.... but the wood is well away from pooling....
Also painted the underside of the shed itself with the bitumen.
The concrete base is also at a slight slant itself... so the water runs off (more or less)
It's only 2yrs old but does seem to be working.
Sounds pretty much along my plans top to bottom:
- Shed
- Floorboards
- OSB Board
- Frame (filled with insulation)
- Blocks
- Concrete pad
I used 75mmx75mm fence posts for the frame.
(At the time they were a multi buy item and I was more concerned with them lasting)
I stuck the insulation in the shed floor (between the OSB and the floor boards) rather than in the frame... though obviously you could do both.
Incidentally I paid for a EPDM roof.... (chucked the felt came with the shed) .. Really really good stuff doesn't need replacing every few years.
I also got a close board shed... as most damage seems to be various creeping plants (Ivy and such) ... and I also filled the spaces with the Evostick space glue cement stuff (the green tubes).. painted over when I painted the shed.
Turns out a tantalised wood frame actually comes with the log cabin/shed so that saved some bother of having to sort that.
Luckily no vegetation where it'll be installed so hopefully not an issue.
Thanks for the heads up on the roof - that's something I need to work out. It's a shallow pitch of 3.8m x 2m on each side. EPDM looks like it'll cost about £200 for a proper job. My only concern is that I can see us moving in the next few years so either leave it for new owner or dismantle - a cheaper, less permanent option might actually be more sensible.
Jigsaw starts this week!
