Shed/workshop flooring

strawb_shortcake

We are in the progress of prepping the garden to have a workshop installed (20×12ft).

We've narrowed down the building we want but now looking at insulation and flooring, my OH is likely to be building  motorbikes at some point so the flooring needs to be durable, we've looked at metal flooring but that's coming out about £1k but wondered if there is any cheaper options we could consider?

What's wrong with paving slabs?

And when you say 'insulation' you have to clarify what you actually mean by this. Nothing can be worse than metal flooring in  this respect.

I've no idea to be honest, this is my OH's project I'm just looking for ideas to try and manage costs. 
The shed will be on a solid concrete base, I'm not sure if it comes with a wooden floor? I assumed so. My OH was looking at non slip flooring which looked like thin metal sheets to lay on top of the wood. Trying to do my own research I'd naively thought my ramblings would make sense to someone more knowledgeable 🙂

We are intending to line the shed walls with insulation thermawrap and line with board.

We built a workshop the same size as yours about 14 years ago

My husband insulated the walls, doors and roof with insulated plaster board and double glazed the whole window area with plastic rigid plastic sheets. Not sure what that material is called but we used that as safer than glass. The windows don't open but that's not been a problem. (and as both are now cracked it was a wise decision) 

The shed is placed on a concrete base and floor was reinforced with double the amount bearers. I think the base it came with is MDF/chipboard. We placed a layer of underfloor insulation down and than another layer of flooring grade chipboard on top, mainly to support the weight of an old fashioned lathe, etc

We then bought a large offcut piece of vinyl kitchen type floor covering and placed it in the high traffic area. 

My son used it to 'mess about' with engines. He finally moved 80% of his stuff out last summer and on inspection the floor is in excellent condition. 

We used a dehumidifier in the winter as damp would have been more of a problem than cold. For heating he used a simple convector heater. (I've no idea how much it cost to heat as this was for my sons hobby/learning - and whatever it cost it was cheaper than going to the pub!)

Concrete floor with a coating of two pack industrial floor paint. Don't use chequer plate (patterned steel or aluminium sheet). It is as slippery as [redacted] when you spill oil on it.

You may find the floor that comes with the shed is a bit flimsy. I'd say your best bet is to lay some studs on the concrete, 400mm spacing should be fine and fill the gaps with insulation board. Then overboard with moisture resistant 18mm ply/chipboard/OSB. If you want something other than wood you can add a final floor covering should you so wish. That'll be solid enough and will take everything you throw at it.
