    Hey all,

    I'm taking up a challenge.

    I'm building a summer house, with a tin roof, I need help on materials. To ensure it lasts longer than Donald trumps reign of madness.

    Walls, starting from the outside layer in: cladding, strips of wood to nail cladding to and provide a small gap, membrane, chip board, nailed to the wood frame, the frame will house insulation, then on the other side more chipboard, completely sealed and waterproof membrane, cladding, then a sofa so I can sit and hide from the misses.

    My question is, does that layout of material sound correct? Is this the best solution to avoid wood rot? If not, then what would you suggest? If so then what type of wood foe the different parts, what membrane, insulation and wood treatment for the frame and boards?

    I've not done this so can't comment, but I joined a Facebook page a while back full of people doing this, tonnes of advice

    I still might build something, once my house is finished ...

    Start with a concrete base. Then 2 courses of brick with DPM on top. Screw wooden wall plates to the brick wall. Build stud walls.

    Place osb3 board around the outside.

    Install insulation inside the cavity's of the stud walls.

    Outside DPM over the sterling board, and clad in your preferred material.

    Inside line walls with plaster board.

    Roof do similar to walls

    Someone else may be able to add a bit more, as I'm not sure if you need a vapour barrier anywhere.

    Regards the windows and doors I'd look out for either good used double glazed units, or units that have been made wrong from factory and are being sold cheap.

    It doesn't matter too much about sizing as you can build your walls to what you need
