Views please. A ground and 5 upper storey, single staircase residential property has a ground floor with entrance front and rear. Gr floor is split into 3 parts, front lobby, central and rear lobby. Within the central lobby there is access to lift and the enclosed staircase, off of the front lobby there is access to two flats. They have recently had a brand new L3 system installed and all new E/L. Currently each lobby on the gr floor has AFD. Their request is this - can they remove the front set of doors and pannelling between the front and central lobby (to make it open), upgrade the two doorsets to the flats with FD30s and replace the doorset and pannelling between the central lobby and the rear lobby to 30 minute resistance? My only thought would be to make the doors to the flats FD60s instead. There are a lot of elderly people within the block and so any evacuation may be delayed or slow. Very minimal ignition sources within the communal area. Staircase totally sterile area. Opinions please?
