Greetings,
We are planning to build a garage next to our single-family house. We have requested several quotes and are surprised by how much they vary. We contacted the following companies: Zapf, Rekers, Hoffmann, and K-Plus. We also noticed that the prices for installing strip foundations fluctuate dramatically, ranging from 3,000 to 5,000€ (approximately $3,200 to $5,300). Wouldn’t a large concrete slab be more cost-effective?
Garage dimensions: 2.95 x 9 meters (9.7 x 29.5 feet), including an extension. The specifications were always the same: Hörmann sectional door, Hörmann door and drive, electrical package.
Quotes:
Hoffmann: 30,000€ (about $31,700)
Zapf: 21,000€ (about $22,200)
Rekers: 17,000€ (about $18,000)
K-Plus: 12,000€ (about $12,700)
Except for Hoffmann, all providers add extra costs for the foundation and crane. Additionally, there is the electrical subcontractor’s fee. Our favorite is Hoffmann because of the material quality and the fact that no crane or foundation is required, but 30,000€+ is quite expensive. With Rekers, we appreciate the TÜV certification and the fact that the electrical wiring is installed flush in the walls; they are also the only provider offering this in their package. Zapf and K-Plus have many dissatisfied customers, and Zapf is still quite pricey.
What are your experiences, or are there other providers known for delivering quality that we might contact? By the way, a steel or wooden garage is not an option for us.
Best regards

I'm glad to hear that, and
It amazes me that windows of this size are possible with plank construction – though I wonder if your car even appreciates that panoramic view ;-)

Therefore, we wanted to have plenty of light. It is also good for ventilation, so you don’t always have to open the door.

HansvonKlaus20 Jun 2024 13:13Hello,
After a long wait, work finally started today. The foundation was just poured, but without any reinforcement. Is this correct, or is this a case of cutting corners in the wrong place? The garage is about 3m (10 feet) wide and 10m (33 feet) long.

HansvonKlaus21 Jun 2024 03:38The offer and contract specify the following:
Execution with an 18cm (7 inches) thick, doubly reinforced concrete slab (plus a 5cm (2 inches) leveling layer to integrate the door track) on a site-prepared base course (approximately 30cm (12 inches) thick capillary-breaking material). Surface flatness according to the requirements of DIN 18202, sheet 3.
The garage was delivered on Monday, and the driver had another customer to serve or deliver to. This delivery included three steel reinforcement mats. The garage is smaller than ours. However, we did not receive any steel mats.
Should I be concerned that the slab might develop cracks over time and that the garage could be compromised? The garage or shell is scheduled to be completed this morning. This means the slab had less than a day to cure, which seems questionable or possibly insufficient.
