Thank you, now it makes a bit more sense I think its a department in Harrow council I need to contact
P.S. there is no gate so its a new construction. we used to be a very safe area but recently a car was stolen from near the house and next month they came back and cut out catalytic converter in day light and intimidated tenants. left without hurry. the police didnt come (said later - they came to wrong address - yeah right)..
