Help designing car storage barn for Porsche’s

I deleted the photo as I decided I should ask him first! I don’t expect to do something that nice but I love the feel of it. I keep a few cars there.

Can you insert steel frame windows in the concrete structure?

What’s the relative cost of concrete versus steel frame? Cost per square foot?

Web joists in preformed concrete can be complicated, so engineered steel would be the answer... a hybrid. Clerestory windows and a lighter roof structure as I suggested earlier.
Check with the pre-formed contractors in your market, you might find one capable of doing exactly what you want.

Concrete is cheaper for larger structures, steel is cheaper under 5000 sf. With a slab, expect $20-30 per foot (or less, depends on location) for engineered concrete.
In some markets there are contractors that pre-form at a factory, while others cast on site )again, depending on size and location).

In the long run, tilt wall is less expensive. A quick search provided some useful info that should answer your questions: https://tiltwall.ca/blog/pre-enginee...-construction/

BTW, I'm not in the business. A lifetime ago my design career involved a LOT of interesting projects, and as a student of architecture it's the kind of stuff I retain.

... which is otherwise useless information

Although I haven't seen it used much in the states, there are some nice structures being made out of site formed self supporting arched roofs. The steel is corrugated and curved on site, big spans are possible and translucent panels are integrated. Supported with concrete columns and then concrete block walls built up to fill in.
Very modern and lots of light.

I have a solution! You can buy my house an 1850replica house built in 1997 on 4.25 acres in NW Connecticut 30 miles from Lime Rock Park racetrack. On it is a 3300 sq ft building set back with its own private driveway not visible from the road that has heat, electric, and bathroom facilities.

I was googling to see what these were. Basically curved roofs like a Quonset hut?

Just curious...

For the size of building you need (2000sf or so) a metal building will be, far and away, the most reasonable non-combustible building in cost. Find a manufacturer that makes buildings the size you need. Sounds like you’re in an agricultural area, so there should be some recently constructed local examples for you to see. Pour a slab, and erect the building. You say that you are in a moderate climate. If so, you may not need air conditioning. If you pay attention to your prevailing summer breezes, you can configure sectional doors to provide both great vehicular access and cross flow ventilation. Solar orientation should also be considered - it’s great to have north facing sectional doors open on a summer day. Provide skylights for daylighting. If you provide skylights equal to about 4% of the roof area, you will achieve a daylight autonomous garage without a lot of solar gain penalty. Working in day lit shops is amazing! If it gets cold where you are, insulating the roof and walls should make it so that you can install unit heaters that will make the place habitable and freeze protected for reasonable energy expenditure. As for fire resistance, consider a sprinkler system if you have the access to water and if you have contents worth protecting.

As nice as tilt-up structures are, they typically aren’t cost effective for such a small structure.

Again, how you site and orient the building makes a huge difference. Understand how and when the wind blows. If you are near an airport, there will be tons of data available concerning wind intensity and direction at all times of year. Really understand where the sun is at all times of the year, and how trees or other obstructions may shade your garage when it’s advantageous and when it’s not.

Full disclosure: I’m an architect. Beware my runaway vision and callous disregard for the needs of my clients!

Here is what I am referring to:

These can be done from a single horse stall to an airplane hangar. Skylights can be incorporated and the steel comes in many colors and with insulation sandwiched in between.
I've seen it used for schools, warehouses, shopping malls, homes etc. It can be quite attractive if the columns and closing walls are well chosen. As Scott mentioned, proper orientation is key to provide air circulation.
What is neat is the fact that it self supports so completely open with no beams.

Interesting info !!! ...…..

That’s what I saw pictures of.

Very interesting and you are right the sidewalls would define it. I wonder if one needs to worry about strong winds lifting the roof?

Insulation in the roof would be key.

Anyone know of any west coast builders that have used this?
