Relocating the kitchen to a new room: effort required for laying the connections?

Good day,

we are planning to move our kitchen to a new room. Currently, the room contains an open office with a sofa and a piano.
Where the black/silver cabinet currently stands, water, wastewater, and power connections have already been installed.
However, we plan to place the kitchen table exactly there.

The kitchen should consist of a kitchen cabinet wall and a cooking island, which should be placed in front of the window front.
The kitchen cabinet wall with oven, refrigerator, and freezer should stand against the wall where the piano currently is.
The cooking island with induction cooktop, recirculating extractor hood, dishwasher, and sink should stand where the white sofa is currently located:

My question now is whether this placement is even possible? The floor consists of Australian maple parquet, which is screwed onto cross beams. Under the parquet there is about 30 cm of insulation material (glass wool), and underneath that the screed.
Is it even possible to lay fresh water and wastewater connections in the middle of the room in this way? What slope must be adhered to?
What is the usual cost for laying fresh and wastewater connections in this case?

Is there anything we absolutely should consider when relocating the kitchen?

Walking works for now. Wastewater and water are also "just a few plug connections." BUT: You can never take direct routes and have to see where you can plausibly connect to the existing line. An island in the middle of the room in the existing building is therefore pretty much the biggest challenge because you usually can't run directly down but have to take complicated routes. Sacrificing the entire parquet for that? Unlike electricity, which can take some unusual routes, you are very limited with (waste)water, mainly due to the slope and the larger diameter of the pipes. If you're lucky, the parquet can be removed and reinstalled without damage AND the joist layer up to the line allows it, then maybe it will work. Sufficient space and slope would then be under the planking. However, the joists must not lie perpendicular to the route you want to take.

That would be a great piece of luck. But maybe you should first say whether it is a house at all or just an apartment, which floor it is on, and whether it is sole ownership. A floor plan with wiring, including the floors below, would also be helpful.

Sacrifice the entire parquet for that? Unlike electricity, which can still take a few unusual routes, you are very limited with (waste) water, especially because of the slope and the larger diameter of the pipes. If you’re lucky and the parquet can be removed and reinstalled without damage AND the beam structure up to the main stack allows it, then it might work. There should then be enough space and slope under the floorboards. But the beams must not lie perpendicular to the route you want to take.

We definitely do not want to "sacrifice" the parquet. Since the parquet is screwed down, we had assumed that dismantling, laying the pipes, and reassembling the wooden parquet would be possible without damaging the parquet. However, I lack experience and expert assessment in this regard. The cross beams actually run favorably for this planned renovation, namely perpendicular to the running direction of the parquet boards. In other words, laying the pipes might even be possible without repeatedly "crossing" the wooden beam substructure, and the pipes could probably be laid in the spaces between. Possibly only one "breakthrough"/"crossing" through a cross beam would be necessary depending on the location of the connection to the drain pipe.

... But maybe first tell us whether it is a house at all or just an apartment, which floor, and whether it is sole property.
A floor plan with pipes also from the floors below would also be helpful.

It is a single-family house from 2006 in ownership. The office and later the planned kitchen are located on the ground floor. Unfortunately, I do not yet have the drawings showing the pipe layouts. However, above the current location of the white sofa on the first floor, there is a bathroom. In combination with the fact that water and wastewater connections are available at the location of the current black/silver cupboard, I strongly assume that the stack runs along the wall to the right in the viewing direction from the white sofa in the picture below.

That doesn't help. You have to find and show the complete plans. All floors and preferably all pipes. It might be more elegant to route water and wastewater through a neighboring room through one or two walls than to break up the parquet or go across the room.

There is about 30 cm of insulation material (glass wool) under the parquet and below that the screed.

Are you sure about that? What kind of strange insulation is 30! cm! Is it not rather only 3 cm of insulation?
