thanks for your insight and advice, the plans were submitted and passed initially without any upgrade or mention of fire alarm, i was planning on putting 3 battery operated ones (kitchen/lower hallway/upper hallway), the building is pre 1950 and i planned to put back the original door, there is a glass panel above the kitchen and also the living room doors, these allow light into the hallway, she wants these covered up.
On her previous visit she started to wonder upstairs, saying where is my fire escape and that i needed all the doors to be fire doors and again the glass panels above the bedroom doors to be covered, the only daylight i get into the upper hallway is via the glass panels above the bedroom and bathroom window.
on her last visit, she came in aggressive, saying the rain water needs to go into the main sewers, i explained that there are no sewers in the back and that they are located at the of the building, it would be very difficult if not impossible to dig all the way under the building, i have neighbours adjoining on both sides, its only when i put my foot down a little did she mention a soakaway, until then she was adamant i take a pipe beneath the house into the main sewers.
I am installing a soakaway 5m from the pipe and calling her back in, i will put fire doors on and cover the panels above the doors, the balustade on the landing i cant do anything and i dont wish to install a main fed heat detector as i would need to have exposed trucking on the ceiling now.
