Hello all skilled builders!
I'm planning to build a mezzanine/loft in my new garage. It's going to be used for storing auto parts and as a "break room/lounge."
It is 5.8 meters wide and it will be 5.5-6 meters deep.
The idea is to place bearing beams on posts along the walls on the sides and attach the floor joists to them, so the floor joists span across the garage.
What do you think about having 3 pieces of 115x115 posts on each side and laying a 66x315 bearing beam on them? Then attaching 56x270 floor joists to the bearing beam.
Looking forward to hearing from all you builders
Best regards,
Marcus

I believe that it is always a good idea to include a sketch to avoid misunderstandings.
Well, it didn't become much clearer for me; can you sketch out a plan, i.e., if you look at it from above?
The penny just dropped, I can figure it out a bit later.
Ha ha ha yes, it's not easy to understand when it looks like a 3-year-old drew it 
I have another suggestion too if you can calculate that as well.
3 pcs of 115x115 posts along the walls on the long sides
Then place 90x315 or 115x315 on them straight across the space (from long side to long side) which is 5.8 meters.
Then screw 45x220 resting on 45x90 studs that are screwed into the beams.
A little blurry picture is coming...

In your first example, you have three glulam beams with c/c 3m and a span of 5.8 m resting on their respective pairs of glulam columns. If you want the beams to have the same height, the middle beam can be 215x315 and the other beams 115x315. From a load perspective, 90x90 columns are sufficient. On top of the glulam beams, you lay construction timber unjointed 45x145 C24 c/c 600 mm.
I myself have a similar local space in this dimension L12*5.9m wide. which will be built with a mezzanine 5 meters deep and 5.9m wide. Is it enough to place a glulam beam across the beginning of the mezzanine as a load-bearing 405*5900mm then 45*220*5000mm 30 cc
Hello!
I installed three 115x115 glulam posts on each long side of the space, then placed 115x315 glulam beams across the space on them.
At the bottom of the glulam beams, I mounted 45x90 studs as support for the 45x220 floor joists that were installed at 60 cm centers.
Then glued and screwed 22 mm floor chipboard on top of that.
I hope you understand what I mean
PS. Have you bought a space from Egenlokal.se?

Marcus

Hi, it's cool that you're sharing info, I appreciate it! I’m egenlonal in Kumla. But how did you attach the limpelarna to the floor? I was thinking of attaching the entresolen to the building's framework, which is visible with 2 at the back and 2 in the middle, what do you think? Best regards
Hello again!
I just placed them on the floor and drove approximately 160 mm long screws straight through the 115x115 glulam post and into the wall. You could place the last post against the supporting steel beam in the middle of the garage and the first one deep in against the wall. That way, you lock the entire construction/mezzanine.
If you're going for 90x405 glulam beams as you mentioned, then go for 90x90 posts; it'll look nicer
