First of all, hipped roof .. have you ever thought about the pitch? And what kind of space arises there and how poorly it can be illuminated under the roof?
Example 38° on the long sides, 45° on the short sides
results in the following possible floor plan

You can see the 1m and 2m lines. To still have reasonably good lighting, roof windows would have to be placed around the 1m line.
-------------------------------
For comparison, gable roofs, where I deliberately left the "holes" that go beyond a normal story height.
38° pitch

leads to over 100 sqm of living space
28° pitch
still leads to 75 sqm of living space
I would therefore reconsider the choice of a hipped roof very carefully.
