: no idea. A "normal" insurance does not cover that. Better to build reserves and have it replaced if there is ever a defect...
Bird strike should not be a problem. The panes are not mirrored. My mother has a large conservatory and year-round feeding. In the first year there were some hits. No longer now. Only when the young birds are on the move does one occasionally hit the glass. Rarely fatal.
: With core insulation it was not possible because of the glass system
The cast asphalt is not really more expensive. You save the screed and the covering. For that you need an underfloor heating made of metal...
We "bit" on some things like the glass system, the ceilings, etc. That definitely made it considerably more expensive.
What I would have done, for example, if money didn't matter (before construction started):
- Solid concrete. So thick that no insulation is needed. Ideally with a company from Switzerland. But after seeing the result now, I wouldn't consider it anymore.
- Property boundary. Retaining wall sunk into the ground and in the visible area with natural stone and corten steel. I once asked for an offer for this and politely declined.
- Possibly we would have made more glass parts motorized and movable.
- Installed shower WCs everywhere right away
- Terrace covering in a really large tile format
- Raiseable floor for the pool
- Flocculation system for the pool
- Elevator even bigger
- The kitchen would possibly be from another manufacturer
- Also plaster and paint the technical rooms on Q3 and install a floor covering.
- Insulated and (centrally) heated pool pavilion
Many decisions were also made with regard to maintenance. I don't want to constantly check, clean, refill here and there... nor do I want to have staff permanently in the house.
We already have much more than we need.
