Starting disassembly next week and hiring a Luton to move it 2 miles down the road to my property. Any tips on how to do this with minimum fuss would be appreciated, if anyone has happened to do this before.

    It is currently sited on a concrete base, I don't have the budget to lay a concrete slab so have been pricing up options for the floor/subframe.

    It will be sited on heavily compacted clay soil - I'm thinking medium density concrete blocks laid and levelled at decent spans on concrete/gravel, 4x2 or 5x2 joists at 600mm centres, 100mm poly insulation and 18mm osb3 on top.

    It will be used as a mancave/office, not a lot of weight apart from my fat a**e and a couple of guitar amps. Desk, chair, maybe some tools but nothing serious.

    Will 4x2 be sound enough for the subframe? Any other suggestions welcomed. A section of the garage will be within 2 metres of the boundary and the apex is at 2.5, so want to keep height to a minimum. Cheers

    As long as your decent spans are decent enough
