Large garage single-family house - prefabricated or brick-built?

However, I am actually very disappointed about how much money is demanded for "nothing special"...

I guess it depends on the expectations. For example, I don’t think a prefabricated garage is something special or necessary. It works! Ps. Is it available as an offer now? I just briefly visited the website

We decided on a masonry garage, which was built directly by the construction company. It is attached to the house and leads directly into the utility room. If something was not sealed properly afterward at the transition from the house to the garage, we were worried that no one would want to take responsibility and that blame would be shifted. In addition, we have a washbasin with hot water on the partition wall to the house, which had to be taken into account with the pipes in the house. For us, it seemed easier to have everything done by one source, it might possibly have been done differently, but we are absolute laymen and did not want to make any compromises. It is then, logically, also in the same brickwork, etc. The cost for this was 38,000 euros. 7x9 meters including a 6 meter (approximately, could also be 6.30 or so) Hörmann sectional door.
A huge advantage was also that we could already safely put everything in the garage during the construction phase and especially right after moving in, and we still can. Tiles, construction equipment, fence, etc. I would have had a bad feeling if all of that had just been left outside.
The prefabricated garage usually only arrives when the house construction is nearing completion.

Yes, you may be right - the question is simply how much more I have to invest to get something "reasonable."

- Longevity, cracking, mold formation, water standing on the base slab, etc.

Maybe a garage doesn't have to be living space, but for the price, I think one could expect a lot more. I don't even want to know how high the margin is...

[...] and various bicycles and children's vehicles.

Around here, it feels like at most 30% actually keep their car in the garage. Not least in times when fewer and fewer basements are being built, garages are sometimes used as basement replacements with storage space and hobby workshops. In that case, people also have higher demands on the equipment and quality.

But I can also understand that for the lot of money, you want something decent. You just must not underestimate the basic costs that every project entails. That makes the garage very expensive per sqm. Actually, the garages should be much cheaper if you have them built directly by the general contractor during the house construction. They already have the respective construction crews (foundation, bricklayer, electrician) on site anyway. They just charge a premium for the convenience of having everything completed at once for the builder.

I only have the best impressions of aerated concrete prefabricated garages, which are already my age and still in good condition. I have already had files and furniture standing in aerated concrete and concrete garages without any faults; cars suffice with a sheet metal garage (although I recommend taking a tiled ceiling). Double garages, which are delivered fully assembled (= as room cells), always have a joint (horizontal for double doors, vertical for single doors). I would always choose single doors.

Large garage with 1 door and open space - double garage with 2 doors and separate space (possibly with open space).

No. A double garage is a two-car garage, usually in the single-chamber variant. A large garage is a collective term for three or more car garages, usually on one level, and if underground also called an underground garage on the one hand, but also single garages, for example for motorhomes, on the other hand.

The prefabricated garage usually comes only when the house construction is nearing completion.

Keep in mind to build a room cell prefabricated garage attached to the house before the roof overhang of the house is in place.

I only have the best impressions of pumice concrete prefabricated garages, which are already my age and still in good condition. In pumice and concrete, I already had files and furniture standing without complaint; for cars, the metal garage is sufficient (although I recommend taking a tile-covered ceiling). Double garages that are delivered fully assembled (= as room cells) always have a joint (crosswise for double doors, lengthwise for single doors). I would always choose single doors.

No. A double garage is a two-vehicle garage, mostly in the single-chamber version. A large-space garage is a collective term for three- and multi-vehicle garages mostly on one level and, if underground, also called an underground garage on one hand, but also single garages, e.g., for motorhomes on the other.

One should consider building a room cell prefabricated garage attached to the house before the house’s roof overhang is in place.

Well, with all the prefabricated garage manufacturers here in the area, it is clearly always referred to as a large-space garage – 6x6m – not a double garage. It also seems to be stated on every manufacturer’s website. But it doesn’t matter, everyone probably has different terminology. In our case, however, it is the large-space garage from Kemmler with 6x6, type IX.
