Improving indoor quality air with ventilation

Anonymous user 4 June 2019 - 2.34 PM

Hi all, Recently bought a flat (ground-floor and basement) in a Victorian mid-terrace on a hill. So the flat has the living-room/kitchen with a suspended floor just above the basement which is not tanked. There are airbricks at the front and the back of the property at the basement level to allow airflow in the untanked basement/cellar. The only problem is that in the past there has been a double storey extension added over a concrete pad which spans the whole house - the extension covers two thirds of the building width and there's a door down to have access to the garden. There's no way for air to circulate at the back of the house, or sides as it's a mid-terrace. It provokes some ventilation issues as there is no air flow, reducing the air quality, making some family members sick (they are allergic, maybe to mold, dust or other). Having a damp, dusty, not ventilated basement doesn't help ... as flat has floorboards and concrete floor at the back. Would you have a solution to improve the air quality without having to knock ceilings or walls down please? Thanks
