I am due to open a new showroom of roughly 200m2 split by a dividing wall (with an access door) in the centre of the room, creating 2 100m2 rooms. Do both rooms require a fire escape?

Chris there is not sufficient information to help, for instance square meters doesn't help, you need the dimensions to calculate the travel distances and the size and location of the doors. How do you get to the outside from those rooms and what is the construction of the partition is there any glazing. Nobody can help without a fully scaled detailed plan.
