The new, much more skilled bricklayers naturally had a good laugh about the construction company.

Especially after I mentioned that the boss personally built the gable.

Also note the perfectly executed support. Here, I will replace the wood with a larger steel plate.

Construction site: red brick wall at the bottom, concrete base, wooden boards above, black diagonal brace.


Roof structure made of wooden beams, red brick gable, and temporary boards on the gable.

Windows, external blinds, and the roof are finished.
The mason narrowly missed the nominal dimension for the kitchen window.

I have been following your house building project from the very beginning.
It’s nice to see you sharing your progress here again.
But I think it has become a bit quieter here because you are spending a lot of time on site.

We are currently building something very similar, so I’m interested in how the staircase is planned.
Is it going to be a steel stringer staircase that will later be enclosed with drywall?

The staircase is a precast concrete element.
There is masonry built underneath.
For the railing, I will assemble a modular system myself.
Due to an architect’s mistake, the staircase ended up being relatively steep. I would not recommend this. However, since I have already used it around 100 times, I don’t find it that bad anymore.

According to the tread step calculation, the staircase should be fine with 63.5 (2*h+T). Our staircase will be the same,...unfortunately, there is often not enough space for an additional step.

May I ask how much the precast concrete staircase including installation costs?
