Cracking garage this, looks big inside

My house and garage build has just started with all the footings poured few days ago, my garage needed a portal frame internal for building regs, its 6500 wide and 7500 long internal sizes, I think the frame is needed for the height as its 3.125 to ceiling and from ceiling 2.4 to peak, I wanted enough height for a ramp and storage area in upper level
