I have now received several quotes for carports, but none of them really convince me.
Since our move-in date is now shifting towards spring next year, I’m considering building it myself, but how?
The plan is to build a double carport with maximum dimensions of 6.00 m wide and 5.50 m deep (19.7 ft wide and 18 ft deep). If possible, I want to avoid having a support post in the middle of the carport, between the two parking spaces and driveways.
Basically, I need four posts/supports with a flat roof on top. For the sides, I might later enclose them all around with open wooden slats or coated perforated metal sheets. Later on, as an option, I might also install a gate.
Additionally, I don’t want to underestimate the snow load, especially with a flat roof. We are talking about around 150 kg/m² (31 lbs/sq ft) or kN/m².
I have somewhat moved away from a fully wooden carport because I think the structure will be too heavy and require too much maintenance over the years.
So, the options left are steel/aluminum or concrete/stone.
What do you think would be the best option in terms of price-performance for a non-professional?
For aluminum/steel, I have someone who can provide the materials and welding expertise—a metalworker.
For concrete/stone and building four columns from formwork blocks or masonry bricks, I could probably manage with my father-in-law, who has years of experience in civil and road construction.
Or is this project perhaps too complex? Due to size, structural engineering, snow load?

You’re not seriously calling that alien-looking concrete prefab garage combined with a canopy a carport, are you?
I couldn’t find any house in your thread history that you plan to spoil with this so-called carport—but nonetheless, I (together with Al Borland and his mother) am confident that this plan will work out if you try to act like a Tim Taylor on a project like this. Your description
sounds like a brilliant plan for a metal garage on installments.
Whoa! Where did you get that price from—a clearance sale, or is that supposed to be for a “kit”?

It should cost €7,000 for the aluminum stuff...

I haven’t seen any house in your thread history that you intend to spoil with this so-called carport – yet I (along with Al Borland and his mother) am confident that this plan will succeed if you try to take on a project like Tim Taylor. Your description
at least sounds like a brilliant plan for a metal garage paid for in installments.
Oops! – where did you get that price from – or is this meant as a “kit”?Well, taste is always subjective, luckily we all have different preferences... And regarding the aluminum carport, yes, it is of course a kit.
