What's the consensus on the best cost efficient construction for a garage (ignoring windows and aesthetics, etc) - I live in the UK, where it's relatively humid during the winter and am looking to build a new garage/unit to house 10-12 cars (which will actually be inside a huge open ended barn/agricultural building - but I'm not sure if that changes anything other than the fact that it won't get rained on/ direct sun). I'm looking to improve security and protection against humidity, dirt, birds... etc. The cheapest material is steel, you can buy big off the shelf steel sheds pretty cheaply, but obviously the temperature fluctuations inside will be huge and attract a lot of moisture. I was thinking of breeze blocking out a corner to use 2 existing walls, insulating and then dehumidifying, but interested in views of people who know more than a laymen such as myself..?
Many thanks
