    Morning,

    I'm wanting to build a summerhouse, and keen to find out all I need to know before starting. The plan is to build something 3mx4m, with the highest point of the roof being <2.5m high. The site is not very level, a few inches drop from one end to the other, and can get very damp in the winter. I'd rather spend a bit more money and time to get something that lasts well. I am wanting to insulate all walls/floor/ceiling. I've found some second hand double glazed doors and windows.

    Please do feel free to give me links to other pages!

    Two particular areas I'd be grateful for advice are:

    1) Would a base like in these pics be suitable, or do I need to build concrete foundations under the piers, or would it be OK to use groundscrews? I'm a bit concerned with groundscrews that the alignment would have to be perfect, and that only a tiny cross sectional area of the wood would be supported.

    2) What would I use to waterproof the base and sides, would damp proof membrane be suitable? For the floor, would this go above or below the insulation?

    Many thanks,


    Mark

    Just realised this is in the wrong place, any chance a moderator could move into the building forum?
