Hello everyone,
I wish you a Merry Christmas and have a question right away.
We started building this month. It’s a single-family house with a concrete slab foundation and a garage, which we are having constructed by a local general contractor.
The concrete slab was poured on Thursday, and we inspected it today.
I’m wondering if there might be a mistake because I interpret the plans differently.
Maybe I’m completely wrong with my amateur observations, and I will speak with the general contractor in the new year. But at the moment, I’m pondering it, and maybe you can help put my concerns to rest.
Here’s the situation:
Our solid brick house is being built using a cavity wall construction and will be plastered on the outside (wall structure from inside to outside: 17.5cm (7 inches) Poroton brick, 18cm (7 inches) mineral wool insulation, 11.5cm (4.5 inches) Poroton brick). On the street side, the garage is set back by 25cm (10 inches).
However, the garage’s concrete slab extends slightly further forward than the house’s slab. To me, it looks like the slab is aligned with the load-bearing walls. That would make sense, but the facing wall also has to be built on the slab and cannot be “floating” in the air, right?!
Am I missing something here?
I’ve attached a drawing and a photo of the construction.
I’m very curious to hear your opinions.
By the way, our general contractor is responsible for the shell construction and the foundation slab.
Thank you ✌️

Yes, we do have that. The first planned inspection is the structural shell check. That was the suggestion from the building savings contract. ♂ Hmm. So he/she comes when the foundation slab is in place, the internal masonry is up, the ceiling has been poured, and the ring beam is completed.
So if it’s already too late by then, there really would have been a mistake here 🙄
I’m not sure if I understood your problem correctly. I just remember that when we laid our foundation slab, I thought it was too small. It was missing several centimeters around the edges. After measuring, I had a sleepless night. However, it turned out that the first row of bricks around the perimeter was built with an overhang of about 5 cm (2 inches). This made the room dimensions correct again and everything was fine. You can see this in the picture… I hope so...
