Planning: Water/Electricity connection for future garage?

Hello everyone,

we are currently planning our dream house together with a home construction company. Since the money is not sufficient for a garage at first and it can only be built later, we are considering whether we should have the foundation for the garage built at the same time as the house.
When asking whether the house connections for water and electricity can be tapped for the garage and the necessary cables laid at the same time, the construction company said: "For the connections of the garage, separate connections must be laid from the street to the garage."

Since I cannot understand this fact, I wanted to ask here how you solved this or whether connections can also be laid afterward without much trouble when it eventually comes to building the garage.

Many thanks in advance.

That is nonsense, in pretty much every new building the cable first runs into the house to the fuse box and branches off from there to the garage.

If it runs directly from the street to the garage, you need everything twice there, like a meter, fuse box, etc. And you will probably also be charged development costs twice.

I would just have a cable laid, the main thing is that power is available at the intended place. It’s more difficult with water, since the connections have to match the later garage. But at least the connection can already be routed "close to" here.

Think about the power connection for an electric car. Have 5x6 or preferably 5x10mm^2 installed. And yes, otherwise everything has been said above,

Well, electricity shouldn’t be an issue, of course you can run it from the house. With water and especially sewage, it depends on the property and the location of the garage/sewer system. If the garage and house don’t share a wall with water/sewage, I also think the effort is too high; you don’t really urgently need a water connection in the garage.

Alternatively, later lay a line from the outdoor water tap with a pipeline system from, for example, Gardena. That's how I planned it for later.

Install a water socket below the outdoor water tap and lead it with a pipe into the garage. So just plan an empty conduit somewhere in the garage's floor slab accordingly.
Back then, we simply had a 5x6mm² 10m cable run from the house for electricity. I then laid it myself under the supporting layer of the paving and later came out in a corner of the carport. I also laid an empty conduit along with it, who knows what might need to go in there someday?!
