Hi Bob
As part of a house - which doesn't requrie a Fire Cert - this does not seem to be considered exempted development if you use velux style rooflights.

===============================
4.If I build an attic conversion do I need permission?
Normally no. However, if work involves dormer windows, permission is needed. If velux windows proposed to the rear, it is exempt. If velux windows proposed to the side/front elevation it is not exempt.
5.Is the area of an attic conversion reckonable in assessing the 40sqm exemption limit for domestic extensions?
No.
===============================
However, as part of an apartment development you may need both planning permission and a fire safety certificate - you may also need a Disability Access Certificate.
Talk to your local authority first of all to get a definitive comment.
Then talk to the building management company to okay this.
Finally, talk to a competent building professional.
Or the reverse order may be a better route.
