Still going well with construction
The weather is good now

We wanted to move in by Christmas 2016, but it was by Carnival 2018

The exterior landscaping is mostly missing, as well as the roof and basement

Yesterday, the first walls were already standing.
PS: The earthworks contractor moved the excavator yesterday. I hope it doesn’t start moving on its own.

You must not be afraid of heights there.

I always get a bit nervous when I’m over 1 meter (3 feet) high. Climbing down a ladder takes a lot of courage from me. Even ten horses wouldn’t be able to get me into the excavator.

The concrete walls have been installed. It’s a pity that these are load-bearing walls. Otherwise, we would have left the concrete surface as is (without plaster, wallpaper, or anything else).

Will insulation be added on top?
Our concrete wall on the hillside side was insulated from the inside.
That sounds familiar. I don’t think I would have gone down into the excavation pit.
The plasterers specifically installed a mobile staircase for me, otherwise I wouldn’t have been able to ventilate during the screed drying process. I can’t reach another floor using a ladder.

Insulation will be added later! First, for example, a black primer layer to adhere the insulation. For the exterior insulation, 120mm (5 inches) extruded polystyrene rigid foam boards.

The soundproofing plans for the outdoor staircase are now also finished. Soon, the access via ladder will no longer be necessary.
