ᐅ Are the costs for a double garage justified or not?

My father built our garage mostly by himself. It was over 50 years ago.

First, a strip foundation was laid, and then he and a coworker raised the walls (mostly large pumice blocks) in one day.

The roof was made with pumice slabs (about 50cm x 200cm (20 inches x 79 inches)) resting on double-T beams.

The floor was then poured with concrete.

The only parts done by companies were the installation of the gate and the side door, as well as the plastering.

I want to say that this kind of project can definitely be done by a non-professional, which can save you money. You just have to have the confidence to do it.

6.15m x 9m (20ft x 30ft) costs me about €43,000 (around $46,000) here in Baden-Württemberg this year. Built with hollow bricks, a 5.5m (18ft) sectional door at the front, a 2.5m (8ft) tilt door at the back (for driving through), a door into the house, and basic electrical work.

Your garage is even a bit larger, so I consider €50,000 (around $54,000) quite realistic. €65,000 (around $70,000) seems too expensive to me, even with a lot of extras.

Are these prices normal, or should we keep looking?

If you have obtained several (more than 2?) quotes, then that’s probably the case. It would be best if you share the exact numbers. How much do they vary? Have you tried negotiating?

If you want to lower costs:
- Do some work yourself
- Build smaller/simpler

Just ask the suppliers where you might be able to save costs. Maybe you made an expensive mistake somewhere.

But as others have already mentioned, the price won’t be halved, if that’s what you’re expecting.

Well, 6.5 x 10 meters (21.3 x 32.8 feet) including a small separated room... that’s quite a size.
I don’t think €60,000 is unrealistic for the foundation slab, exterior and interior walls, roof, and door. However, that doesn’t include any special flooring (do you need that in a garage?) or special doors/windows. I would simply get three local quotes.

You can also do this without a concrete slab... We are getting a double garage with a storage room, 9 m (30 feet) long, also built with masonry. We will just have it paved. The cost for the garage shell alone is already over 20,000.
