I am in the planning stage for a garage construction with a basement where the garage will be placed in the basement. This is due to the zoning plan's limitation on the ridge height, 3.5 meters and a maximum of 50 m2 building area.
The garage will be dug down and will thus be built on a slab with built-up leca walls.
To save time, I plan to set up a Lundqvist prefab timber building (8.4 * 6) on top of everything. In this, I envision an office area of about 20 m2, and the remaining part will be storage for all the junk one accumulates.
The questions are which joists should I choose to get as low a building height as possible. The span will therefore be 6 m and I want to avoid columns in the basement. Cost-effectiveness is also a parameter at this stage.
I have tried to google the answer, but I get very confused by all the different names for the lightweight beams and maximum deflection, etc. I hope someone can share their knowledge/experience regarding my options.

If you want to minimize the floor height while still covering a 6-meter span, steel or glulam is the way to go. The question is, what floor height do you think is the maximum?
If I understand correctly, @oobum's response means that I should manage with 66*315 glulam?
Is this calculated for a normal living area? or storage?

Best answer
I usually calculate myself instead of using various apps. In the Moelven app that oobum has used, there are apparently some assumptions that are not disclosed. I suspect that all options assume the use of screw-glued floor chipboard on top of the beams to meet the deflection requirement. If you do it with 66x315 mm glued laminated beams at c/c 600 mm, it will definitely be good.
