Can you elaborate ?
Has the area been completely redeveloped into a residential area ?
The country is full of residential areas that used to have factories or warehouses.
Does it still look like an industrial estate ?
The only issue that I think if it residual industrial pollution. Is this your concern,
ordo you have other concern.
If it is, it should be easy to research the history of the site and find out what find of factories were there and assess the risk.
