My handyman agreed to add 2 BR's in attic...how should I plan?

[Steve DellaPelle]

The unit I am living in is a 1 BR/1 BA on the second floor of the building...the door to the attic is right outside my entrance and goes up to a big open area that USED to be 2 additional bedrooms, however, it has been vacant for years as there was a fire in the 80's.

My handyman took a look and agreed that he could definitely add the 2 bedrooms, no problems...

I know egress windows will be a major factor and I am also looking into the heating and electric to make sure it is linked to my unit's heater/panel.

What else should I be looking/planning for?
