Hello everyone,
we are currently facing the decision on how we want to design our attic. Since we actually have all the "needed" rooms on the ground floor, only 3 rooms will be planned there as expansion reserves: storage, possible guest room/children's room/office & hobby room.
The floor plan (14.5 * 10.5) is so large that we basically don't care about hard-to-reach slanted roof square meters in the attic. The roof must have at least 30 degrees and be a gable roof.
My question is which option is the financially best solution in relation to well usable space:
Values I googled were approximately: 0.5m more knee wall about 10,000€, 1 degree more roof pitch about 800€. I cannot estimate the cost for an insulated air space – would the screed also have to be extended to the roof edge there?
I lean towards option 3 – since the roof is already very large. Thank you very much if anyone has some input here.

My question is which option is the financially best solution in relation to well usable space:
[*]Roof pitch: 30 degrees + 0.5m knee wall + 0m air space (i.e., insulated setback from roof edge)
[*]Roof pitch: 30 degrees + 1m knee wall + 0m air space
[*]Roof pitch: 38 degrees + 0m knee wall + 0m air space
[*]Roof pitch: 30 degrees + 0m knee wall + 1m high recessed, insulated "air space" (Dr?)
