Hi there

We have 2 sets of double doors( push bar fire escape doors) these are only exits. On one side of our room I've completely sound proofed that side of the building in order  to keep the neighbors happy, the weakest part of the sound proofing is the doors. Am I able to build a mini hall way and install another set of doors that swing both ways I front of the current doors. In effect making a kind of mini porch on the inside.

The doors  would be 1600mm wide, the same as the current doors and be 1200mm in front of the current doors

I would obviously make sure the little room between the two doors is fully lit

 

Cheers 

Duplicating the doors to make a lobby is not an issue providing that they open to a minimum of 90deg so as not the encroach on the existing doors.  You may want to duplicate the fire exit signage above the doors
