Building a motorcycle shed

[BrickyBrian]

I would like to build a shed around ten feet wide and 25 feet long to hold the growing number of motorcycles my son's have with the prime purpose being fire proof and affordable. Could anyone make a suggestions as to what material to use and the roofing?

Don't know what you want it to look like but at that rough sizes you could get a fridge lorry body.
It won't be quite as wide on the inside but the good thing is they're insulated so you don't get condensation, and relatively secure

In the interests of security I would be building it from blocks
