I am in the process of planning a large raised deck.
I thought it best to attach a ledger board to the side of the house as it will be about 4ft above ground level. I want to create a flush walk through from inside to out.
Is it o.k to attach the ledger board over the air vents with a 10mm gap or would that not leave enough space for adequate airflow.
Advice welcomed
