Advice on building a wall
Hi all, I live in an old apartment block on the 4th floor. At the back is what used to be a little balcony with a wall about 1 metre high. This balcony has since been enclosed and incorporated into the kitchen. Now I have a damp/condensation problem, partly because this wall was never designed to be interior and is only single skin (10 cm thick). What is the best way of making this a 'proper' wall? I would like something not too thick (to minimise the amount of space I'll lose in the kitchen), yet still solving the damp problem. Lightweight materials would be best as I'll have to carry whatever materials I buy up 4 flights of stairs! Should I go cavity wall (with insulation?) or just build a second skin of concrete blocks? Obviously I'll be removing the radiator and pipes! Thanks for any advice.
