I think , according to the number of members who complain of damp in their Turkish properties, that dampness in Turkish buildings is akin to the windows, i.e. it is built in to the property !! Turkish builders have, for many, many years, built homes, offices, bars, restaurants etc. without EVER installing air-bricks, or any kind of ventilation ( apart from the aforesaid windows, that is ) !! Constant ventilation is a MUST in any building, no ventilation = beacoup de dampness !! You are welcome .
