Hello forum,
I am currently planning a small weekend house, measuring 6 x 8 meters (wood frame construction).
It will have a gable roof with a pitch of 33 degrees.
Roof covering: first a chipboard, then roofing felt, and metal sheeting on top.
I do not want to install a ceiling; instead, I want the roof slope to be visible from the living area inside. There will also be no interior walls, creating a completely open space measuring 6 x 8 meters.
Can the roof structure be designed to allow this, or is 6 meters too wide for this open construction method?
If possible, what thickness should the rafters have, and at what spacing should they be installed?
I assume a horizontal brace needs to be placed near the ridge between the rafters. How far below the ridge should this brace be positioned?
Regards, der_andy

As you correctly recognized in the title, this is a question for a carpenter.
