Outdoor water tap was not connected!!!

Hello first of all,
we have a small problem. We already had the handover of our new building and shortly after realized that one of the two outdoor water taps does not work. The construction manager immediately sent craftsmen to fix the problem, but they couldn’t do anything... they only called around the world to find out which colleague installed everything. Well, now it turns out that one of the outdoor water taps was actually not connected. And it’s the one that goes out the kitchen window into the garden. We were now offered, alternatively, to connect a new faucet from the utility room... this would mean the water tap would no longer be in the garden at the back but on the right side of the house by the carport... totally impractical and not as planned.

Another possibility would probably be: to lay the pipe behind the new kitchen unit (just installed by the kitchen builder for about 10,000 €) and bore through into the utility room... in order to connect the original tap... all very elaborate in our opinion or at most I would only find it okay if it’s concealed and we are a bit afraid for the new kitchen.

Either way, it will be complicated. Either partially dismantle the kitchen and tear open walls or make a new bore and seal the original spot...

What would you do or recommend us? And can you claim money back if the water tap is relocated, so not installed as planned? Thanks in advance.. :)

Wouldn't bother me at all because it’s not my money. If something breaks, you’ll get it replaced anyway. Better have it installed in the garden... Our neighbors saved a few euros because the extra installation in the back cost money for the outdoor faucets. Now they have to pull a 40m reel all the way to the back every time to water. That would be too annoying for me.

Are you sure that the valve was installed as a blind end without connection, and not just turned off due to frost without documenting where the shut-off valve is located? If the "forgotten" fear should prove true, then my motto would be clear: Fix it - without nonsense, without ifs and buts, no whining and no ill intent, and without damaging other trades. At the expense of the forgetter, of course.

Is the entire supply line actually missing? Or what exactly does "not connected" mean?

As an alternative, one could also agree on the installation of a well in the garden, if that helps you and is possible (electricity, groundwater accessible, etc.)

how can something like that happen?
So you have a faucet including connection fitting in the house wall but no pipe leading to it on the inside?
The plasterer should have noticed that at the latest when plastering over an open pipe on the interior wall.

If it bothers and burdens you: have it improved. We also have an outdoor tap WITHOUT an internal shut-off valve! When I inquired, I was told that the water pipe runs from the utility room to the outdoor tap and then to the angle valve in the kitchen. Allegedly for hygiene, so that the outdoor tap is also regularly flushed. If that is really the case, would that be possible for you?
