ᐅ Building a Garage Yourself – Materials and Cost List, Does This Look Correct?

Hello everyone,

Originally, we planned to build a carport, but the idea of constructing a garage ourselves never completely disappeared. We have a building permit / planning permission, but it was originally issued for a timber frame garage. Accordingly, the structural calculations are available for that.

To make a final decision, I roughly compiled a list of materials and prices to estimate the costs. A master mason friend is available to help. Most prices were based on online listings or existing quotes from the current building. Only for the garage door do we have concrete offers.

What do you think? Is something major missing or are our prices completely off?

Garage made of 24 cm (9.5 inches) Ytong blocks, 7.00 x 6.50 m (23 x 21 feet), shed roof with 40 cm (16 inches) sandwich panels, sectional door, floor slab existing, no earthworks necessary:

24 cm (9.5 inches) Ytong blocks: 2,000 EUR
Adhesive, 15 bags: 240 EUR
Ring beam with reinforcement: 2,000 EUR (this is where I’m most uncertain)
Roof rafters 8 x 20 cm (3 x 8 inches), 1 m (3 ft) spacing: 500 EUR
Sandwich panels with 40 cm (16 inches) insulation: 1,500 EUR (possibly extra costs for higher insulation)
Sectional door including installation: 3,200 EUR (promotional door 2,500 EUR)
Gutter sheet metal: 170 EUR
Rain gutter: 120 EUR
Structural engineering adjustment: 500 EUR
Exterior plaster: 500 EUR
---------------------------------------------
Total: 10,730 EUR

There would also be a potential extra cost for a cement screed (45 m² x 25 EUR): 1,125 EUR. I will do the electrical work myself.

How realistic do you find this estimate?

How can I contact you outside the forum? The private message function seems to be disabled on your account.

If you both happen to be online at the same time...

That way, the other person will have seen it (and theoretically third parties during that short time), but the addresses won’t remain publicly visible indefinitely. Alternatively, you can wait until you are allowed to send private messages, which is usually after about 150 or 200 posts.

Hello

20cm (8 inches) slab: 6.8m³ (8.9 cubic yards) of concrete = about 600 euros including delivery.
200 euros for rebar.
One day (generously estimated) for formwork.
3 hours for concrete pouring and leveling.
Do the math yourself.

That doesn’t quite add up. Just look at the cost of the reinforcement mesh. Top, bottom, plus overlaps, you’re already spending more than 200 euros. Then add spacer bars, chairs, etc. ...
It all adds up quickly.
You won’t get waterproof concrete for that price including delivery either.
Five years ago, I would have agreed with you on everything.

With this new account, which was necessary due to the incompetence of those involved, I do not yet have enough posts to use the private messaging function. This setting is preset and not something I have disabled myself. Either follow 11ant’s suggestion or just ask here...
