A double garage build thread - but not a double garage!

I can now appreciate why you were so worried about the kid with the Cardigan!
great thread

Thanks. More to come (still working on it). But actual employment keeps getting in the way :-)

subbed! this is making me depressed about my plans for a measly double!

Did you add any heating? i'm thinking of insulating the entire slab and putting some underfloor heating in.

Go big or go home! or in my case, go big at home :-)

I did think about underslab insulation, but in the end decided against it as I wasn't really sure about putting a two lifts on a slab basically floating on a load of Celotex. Probably would have been OK (and I am sure someone will advise shortly). Underfloor heating would have been a bit of a faff with the lifts and when I was doing the house, trying to find someone who would do wet underfloor heating was nigh on impossible (to the point that I went with electric).

I had two aircon units fitted, as these are air source heat pumps they also heat in the winter (reasonably efficient too).

Overall the insulation of the building does quite a good job, stays noticeably cooler in there on hot days (with no AC on) and stays warmer on cold days. The AC guys specced 2 units to cover the floor area, but to be honest, one of them on for 20 mins makes the whole garage T-shirt compatible in the current temps (5C-10C) so I think I could have gotten away with one (plus a jumper for really cold days).

It's not quite finished yet, life (and work) has gotten in the way, although it is operational (and has been used quite a lot). Hoping to get some updates out soon. :-)

Does your scissor lift shuttering allow for some structural connection between the concrete under the scissor lift feet and the overall building slab pour on top of it?

i'm wondering how that's done - perhaps by pouring a deeper square slab first under the shuttering, and leaving some adjoining rebar exposed for the floor level pour?

Pretty much that. Manufacturer gave specs for the thickness of the slab and the depth of the hole. Really the weight is all taken on the slab underneath (basically the bottom of the holes) which extends by over a meter around the holes (can't remember exactly but the manufacturer specs were followed) and rear left sticking out of the top to tie it into the main floor slab. The main floor slab holds down the lower slab and stops it moving, bit the "under-slab" (for want of a better term) is pretty big on its own.


Still not finished the dammned thing (work has been mental over the last 12 months). I have some updates but want to finish it all off in one go on here :-)
