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?

Well, I would suggest consulting a structural engineer or architect who can design and calculate that for you. It’s also important to ensure that it doesn’t collapse or lift off under wind loads.

If you have no experience with self-building, simply go for a construction kit. They are available in steel, wood, or aluminum, with your dimensions starting from 4-5,000 euros.

A wooden carport costs around 4,000–5,000 euros from the online shop. The local carpentry wanted 20,000 euros. The aluminum version should cost about 7,000 euros. I’m still waiting for an offer for the concrete version.

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.

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

Whoa! Where did you get that price from—a clearance sale, or is that supposed to be for a “kit”?

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.
