Protected escape route in ***

[Guest Lydia]

I am currently renovating a property to turn it into a 4 bedroom *** and have a question regarding protected escape routes.

Most the existing walls in the property are brick masonry and therefore I assume have adequate fire resistance. However there is a short length of plasterboard wall (shown in red on the picture) leading into the kitchen. I was wondering if this needs to be fire resistant plasterboard? Fire rated plasterboard will actually be applied to the whole of the kitchen ceiling (as well as the hallway), therefore the kitchen is effectively fully fire resistant anyway. Also, does there need to be a fire door between the kitchen and the hallway? Again, if the kitchen is fully fire resistant then maybe not?

Kind Regards,

Lydia

Here is the guidance: https://www.cieh.org/media/1244/guidance-on-fire-safety-provisions-for-certain-types-of-existing-housing.pdf

Depending on the type and thickness and number of layers of board the existing plasterboard may be sufficient.

If it is a single dwelling, two floors then there is no problem
