Currently working with my in house architect ( I work for a home builder), to design a house with a 5 car garage. Plan on keeping my '17 Grand Sport and taking on a Factory Five Cobra as a fun project for my dad, father in law, and myself.
Saw this picture of 4 post on CF and saw the garage was 9'9." Currently the garage in question is setup for a 9' height, and I can't raise the garage height very much due to the rooms above it. I'm hoping we can find a way to raise the right side of the garage up to 10', but if not Am I out of luck on a 4 post lift and storing the ffr cobra above the GS? The garage doors wont be an issue since I'll be working in the back of the tandem garage.

WOW!!! That's going to be a BEAUTIFUL house, you are very fortunate. I love my new 17 GS and expect you do yours as well. I always like the garage entry on the side or rear elevations, however that's not always possible depending on the lot and others factors.
Enjoy it, hope construction duration doesn't drag on too long.
I'm not an engineer/designer, but would there be a way to sink the foundation of the garage area to accommodate?
Thought about that, but we have expansive clay in Houston, and our foundations are essentially "floating" post tension concrete slabs, so I wouldn't be able to counter sink that area without astronomical cost to reengineer the foundation. I'm going to see if he can either raise the plate height by 1 foot on just the area at the furthest right, or if there's enough room/ structural integrity to keep the plate height the same, and just do a angled vault up to my desired height.
My main issue is how the garage extension does/doesn't tie into the second floor.

You can for sure do this if you floor is on 2x6 just have him cut r raise & make the angle vaulted just over the roof area of top of the car.
OP here let me say this to you on the 4 post lift just to help you on the c7 get the wide 4 post lift man you really need it I don't have the wide one, & I have to push my side rear views in to get the car between the 2 outer rails going in. Robert

Add a few stairs up to the living area above garage. Your architect didn't suggest that??
He tried it on his autocad and it kicked it back citing the 2nd floor plate height. I don't work for a fully custom builder, so the mere fact that I've gotten them to allow me to tweak that house as much as I have is a semi-miracle.

Hey OP, you should be able to stack those 2 in a 9 ft garage as long as:
* Both cars are about 50 inches tall or less.
* The 4 post lift posts are <9ft tall.
* The 4 post lift has adjustable stops (I have 2 BendPaks and they have adjustable stops).
* Here's how the math works: 2 cars at 50 inches each = 100 inches; ramp = 4 inches; need 1 inch above lower car to drive it under = 1 inch; need to lift car off stops = 2 inches. Total 107 inches. 9 feet = 108 inches, so 1 inch to spare.
Please note the actual height of a C7 is listed at 48.X inches, and that's very accurate. Not sure about your Cobra, but it might even be lower. We have a GS now - same height as our '15 Z51. So you might have a bit more leeway.
I know this math works because I worked the math prior to knowing if I could stack a C7 over a SRX and later a Terrain. I adjusted the stops so the SUV had 1 inch (literally) clearance, and the C7 fits perfectly.
This worked so well I got another stacker and bought a chromie - same height as a C7 (I googled, got the answer, and it worked perfectly too).
So, make certain you have at least the 9 feet to work with, google the height of the cars you're working with, check the stats on the lift you have/want, and hopefully it'll work out for you!
PS: don't forget to have them tuck the garage door up to the ceiling and use a side-mount motor. You'll need the extra room over your hood or trunk that would hit if the door isn't tucked up. Your builder will know how to do it - I think it cost me about $300 to do the one side when we built our home, and about $500 to retro fit the other side when we did it last year. This won't be a problem if you put the lift deep in your garage ahead of where the doors come up, but it would be an issue if you have your lift near the garage opening.
PS PS: Robert Miller is right about getting the wide lift. Both of mine are the wide models - I could get by with it on the C3, but not the C7.
I would like to say it is a beautiful home. I wish I could have something like that built.
First let me say that I am not an architect, engineer, or builder so what I am going to suggest probably won't work or will destroy the look of the house. Maybe I have watched to many home improvement shows, but here you go:
1) Run a beam the length of the garage between the single wide side of the garage and the double wide side of the garage. This will allow you to terminate the load for the second floor at the beam.
2) Raise the outside walls of the garage, and the roofline 12". Raise the garage ceiling over the single wide side by 12". Use 8' garage doors. Raising the roof may eliminate the ceiling slope on the outside walls of bedrooms 4 and 5.
3) Add another window to bedroom 5.
Yeah, I've probably watched too many home improvement shows.
Hi OP, when we built our 2nd house (also in Houston) we had the architect raise the whole first floor ceiling by 2 feet to make it a 14 ft high ceiling across the entire house. Reason for this is because I like tall ceilings and also raises the garage ceiling height as well. I am pretty sure its doable on your plan as well.
We set our house on the lot and adjusted the garage height by raising the foundation height and lowering the garage Floor. I ended up with 12' ceilings and 10' tall doors in the garage. It was minimal in cost mostly handled through the excavation. I think it was only about $1k in difference in concrete cost if I remember correctly.
Looking forward to getting the lift etc put into the new house so I can have everything back together again. And do some landscaping so it looks a bit less commercial.
I’ve a 10’6” clearance and if I want to work on a car on the four post I have to use an office chair bottomed out. Can’t stand up.... For parking even with what I have the 65vert and 69 Mach 1were tight
I'm not an engineer/designer, but would there be a way to sink the foundation of the garage area to accommodate?
If height restrictions are not an issue you can lower garage slab as long as you can pitch away and increase door size.. Just did one and they had a 9' door with a 12' ceiling height.

Talk about making the most of your existing space. Nice toybox
Just in the process of building a new house and my specs were to have an 11ft ceiling in the garage. Hoping to go with a single lift plus a double. It will be 23 x 37. I'm hoping that I will have room to have one in font of the other.
