We are looking to purchase a property which has an extension and converted garage but learned today it has no prior planning permission. We are not overly worried about this as the works were over 10 years ago so we know it’s unlikely the council will be after us.

The issue is that we would like to make alterations to the existing extension (new windows/removal of outside door) and potentially extend onto the top of it. Are we likely to get planning permission refused for this because the initial extension wasn’t approved? Any advice would be appreciated, thanks.
