I agree Kbdiy. If I was a landlord I too would certainly have the tenant run any modifications past me first. I did ask the landlords permission for the kitchen and they agreed. The kitchen at present cannot accommodate a fridge or other white goods. Although the kitchen imo is not fit for purpose, I believe the landlord is in not obliged to change it. There was room fro a washing machine and a cooker only and the landlord said the fridge, dryer etc could go in the lounge area!
