The structural engineering costs also amounted to a five-figure sum for us. Fortunately, this was quite early in the construction phase.

The two terraces are gradually taking shape, bit by bit. Slow and steady wins the race, as the saying goes. We also have a squirrel on the property. It seems to live on the west side and, during its journey to the hazelnut bush on the east side, it always passes by the lower children's rooms. Of course, the kids are thrilled to see the fluffy visitor and enjoy watching it scurry by several times a day.

Oh, and I was already complaining about my 1m, 1.3m, and 1.5m L-shaped retaining walls over 67m (219 feet).
That’s a whole different level, my goodness!
Everything, including the terracing, is enclosed from all sides.

The setting work is now complete. At first, no one realized how time-consuming it would be. A consistent layer of lean concrete was applied underneath, and the parts were welded together. The installation was done very meticulously (to our delight). Many working hours went into this, at what I would call a fair hourly wage. We are pleased with the result.

Now we move on to the next steps, such as planting. The neighbors are also eagerly anticipating this, as they are not too fond of the concrete. The concrete walls visible to the neighbors will be "hidden" with plants, agreed upon in a cooperative way with them. This is also new territory for us. But I, in particular, am really excited to immerse myself in the flora. That means, for now, hauling quite a few wheelbarrows of topsoil up the slope...

The neighbors will get used to the concrete as well. It’s just unfamiliar at first because there was nothing there before.
I’m looking forward to the final result. It will definitely be great.

Don’t dive too deep.
At least once a week, I realize I’m missing about 5,000 sq m (54,000 sq ft).
