extending concrete slab base for log cabin

[magooagain]

If you barrow through the house,check the barrow clears the doorways.

Do an empty run to check.

You may need to fix protection to the frames as a heavy barrow can be hard to control for someone not used to it.

Pack out any door thresholds as you don't want to be spilling concrete.

The better prepared you make the run then the easier it will be.

Make sure the tyre is pumped up on the barrow.(DONT use a solid tyre barrow)

Good luck.

The most important consideration here (I have two Tuin cabins) is that the base is 100% level. You can get away with a fair bit of tolerance or a shed, but not a cabin.

One the plus side, whereas a shed base generally covers the entire footprint the only important bit for a cabin is the walls. As such, you can level up with slithers of timber (make sure they're tanalised) for the foundation beams.

If you're not level at ground level, you'll have a hell of a job piecing the beams together as they are machined to pretty tight tolerances. Out of whack and you'll have gaping holes at best and lots of problems down the road.

No issue with extending the base - but bear in mind the above.

Personally, I made a timber base for mine as they have 100mm of celotext insuation (and 50mm in the roof)

I was considering a timber base made from 6x2 so its cost effective. But a timber frame would ideally have to be above ground and the 150mm it adds to the height means the 2.5m permitted development height limit is exceeded.
