No access to "attic space" above living room in bungalow: how to insulate?

[caljane]

Hello,
We live in a bungalow with an attic accessed via a stira in the hallway. At the front of the house, the living room juts out about two foot beyond the rest of the house. A plumber working in the attic brought our attention to the fact that the "attic" doesn't extend as far as this jutting-out section of the living room. So, I suppose, it is just empty space without any access to it from our attic. As a result, it isn't insulated at all.

That section of the room has had some mould on it. I am now thinking the lack of inslation might be the reason? How could I go about insulating it?
Thanks!

Is the 'jutting-out section' roof pitched or flat?

Thanks for replying. It's pitched.

Put a hole in the ceiling for access, insulate and close back up the hole? Our garage juts out to the side and there is an access square in the ceiling to get into the space. All that is up there is insulation.
