Oh, whi. Have you read the latest revisions to code? Sometimes, it's necessary to provide a second means of egress, even if the "spreading phenonmenon" means replacing a window with a door.
BBf -- understood -- But these replacements of window for door are to provide access to a space not previously accessible (e.g. Copley Plaza sidewalk cafe on St. James) or to change circulation patterns (e.g. Isabella Stwart Gardner's new entrance) or to open a previously limited access wall (e.g Filene's >)
as the Copley Plaza folks said about the $20 million being spent to update the hotel in celebration of its 100 birthday this year -- including: a new roof-top fitness center with roof deck; new mechanicals; renovations to the famous Oak Room restaurant; renovations to the elegant lobby; and the new outdoor cafe:
"Paul Tormey, the hotel’s general manager, said the plan includes replacing a window with a door onto Saint James Avenue...to animate the new restaurant and bar and bring some life to that corner...We are such a large and imposing facade and this will soften it up a bit.”

"The Fairmont Copley Plaza will also be adding a new state-of-the-art fitness center on the roof of the building, which will include 2,400 square feet for machines and free weights, as well as a more than 700 square foot outdoor deck perfect for relaxing before or after a workout. The fitness center is scheduled to debut in August of 2011.
The hotel’s signature function space and elegant lobby will receive some enhancements as well. The project also includes upgrades to mechanical and electrical infrastructure, as well as heating ventilation & air-conditioning improvements, including a new sidewalk on the St. James Avenue façade of the building..... The guestroom part of the project will begin in the fourth quarter of 2011, and the hotel anticipates completion by the celebration on its centennial in summer 2012.
