I'm planning on doing a rear extension and as such, I will be left with what was the old kitchen (around 3m x 3m) as an inner room with no openable windows. The plan is to split it into a 1m wide corridor that will allow access between the current entrance hallway and the new extension, leaving a 2 x 3m area that I'd like to use as a small study.
As the study area will have an entrance directly from the hallway then I think I am ok with regards to Part B, but Part F doesn't seem to have much guidance for my situation. Paragraphs 5.14 - 5.16 talk of ventilation of habitable rooms through other habitable rooms/conservatories. But I am going to be ventilating what is presumably classed as a habitable room (study) through a hallway.
The hallway contains the front door which I hope will provide sufficient purge ventialtion (or does it have to be a window?) and I am replacing the front door so will make sure to include trickle vents. Do you think I can follow 5.14-5.16 even though my internal room will be ventilated through a hallway and not another habitable room? And when it talks of a permanent opening between the two rooms, can this opening be fitted with an internal door to make it a separate room or does it have to literally remain permanently open? I don't know many people who have a permanent opening through to their conservatory with no door so assume I am being too literal.
