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 can use the dimensions of ready-made kits as a guideline if you don’t want to do the calculations yourself and just add a little extra for safety. Having some knowledge of joinery techniques helps; otherwise, watching YouTube videos on common mistakes to avoid and how to do it correctly is a good idea. I would choose wood because I simply enjoy working with this material. You could probably even park a tank on the roof later – whatever. The combination of delicate design and high stability is always expensive – and it shouldn’t be costly if I understand the original poster correctly.

Well, taste is known to be subjectiveOr maybe not: as I said, I don’t know your house, so I automatically can’t picture how the carport and house fit together. But I consider another connection even more important: that between the quality of the materials and the skill and talent of the builder.https://www.instagram.com/11antgmxde/

Well, taste is known to be subjective, and luckily we all have different ones... Regarding the aluminum carport, yes, it is of course a kit.You won’t find any ready-made structural calculations online here, nor will anyone send them to you via private message.
So you will either need external help—someone who can provide drawings and structural calculations, order materials for you, and assist with assembly (for a fee)—or you can choose a kit.
My father once got a kit from the local timber supplier.
I hired a carpenter who did the drawings, bought the materials, and cut everything to size. We primed the wood beforehand and helped with the assembly.
In the end, it cost about €9,000 for a 9 x 6 m (30 x 20 ft) structure including a partition wall and a sliding door, used as a shed.
Edit:
If you paint it at least three times, maintenance is minimal.
We applied two coats of primer and one coat after final assembly.
Dirt can be cleaned off with a water jet, and after almost two years there has been no weathering, despite being on the northeast side in the shade of the house.

T_im_Norden9 Sep 2020 07:39Carefully check how the kit was calculated; usually, the wind and snow loads included are minimal. If there is no side wall included, it was likely not considered in the calculations.
There is a good reason why kits that take these factors into account quickly reach around 7,000 to 8,000 euros.
In the end, the difference compared to a carpentry company is not that big anymore.
We have a quote for a double carport with a storage shed, skylights, doors, roof, and drainage, measuring 6.50 by 9 meters (21 ft 4 in by 29 ft 6 in), for 12,000 euros.
