I would also choose terrace 2. With small children, the pool would be too close to the house otherwise. With terrace 2, you would have a few more meters to keep the kids from getting too close.

Terrace 2 for the pool
Terrace 1 for the children
There is nothing better than being able to leave small children alone for a short time. I would be worried with a pool.

Many thanks for your feedback! The pool is now planned for Terrace 2. The landscape gardener has arrived and is working from the lower side (the valley side). We reached an agreement with a (non-adjacent) neighbor. We want to get rid of about 300m³ (390 cubic yards) of rubble, and he can make use of it...

Since the last posts in mid-May, not much has happened, partly due to the holidays. The structural builder has completed the backfilling in front of the house and the exterior stairs. The roof frame is now finished, the tiles were delivered today, and the roof will be covered by the end of this week. The electrician has started work, plumbing begins tomorrow, and the small windows and doors will arrive this week. The large south-facing windows are expected in two weeks.

The shell construction has also been inspected. There were only a few items on the punch list. They have really done an excellent job!

Now we need to accelerate the pace. The apartment lease ends at the end of November. This will be a busy phase, especially with the three little ones (5 years, 3 years, 1 month).

And the digging continues. Half of the pile is already gone.

The roof is now mostly covered. The tiles for the snow guards were missing. These will be replaced later, and the opening will be closed. The next step will be the flat roof waterproofing (for the balconies and terrace). This is a critical task that will hopefully be closely monitored by many attentive eyes. However, part of the scaffolding must be removed first.

The manifold for the ground collector has also been installed, and the pipe from the heat pump to that point has been laid. Tomorrow, I can weld the joints. After the rainwater filter, valves will also be installed. This will allow controlling whether the water goes to the pool, irrigation, or infiltration. The infiltration is carried out using drainage pipes above the ground collector. This way, the collector receives additional energy during the cold season, as water is rarely needed in the pool then.
