Size of utility room / space in front of washing machine

Stacking is only a makeshift solution in my opinion! The heights are definitely not comfortable... The washing machine is too low and the dryer is too high!
How much space will you have in front of the appliances if you widen by 30 cm?
Our podium feet are built from masonry (before the screed!) and the slab on top is cast concrete! Here is a picture.

Thank you for the photo! It's really convenient with the basket directly under the machine! With 30cm more, we would have about 1.30m in front of the washing machine. I calculated 70cm depth for the washing machine including connections. I set it up in the bathroom in front of the tub, and I found 1.15cm also okay. I measured that with the laundry basket.

Regarding the height - my husband just said that the laundry basket still stands on the floor, and the higher the washing machine and dryer stand, the higher I have to lift the laundry, and I have to bend just as low... only when taking it out I can just let it fall into the basket or are we making a mistake in our thinking now??

We have stacked the washing machine and dryer on top of each other, and I find that quite practical. It saves space, and the dryer (which is on top) is at a comfortable height to load the laundry directly from the washing machine. However, I think this is a matter of taste and also a matter of getting used to it.

If you are not yet sure about the space or cannot imagine it, try taping the current floor plan of your utility room as well as the furnishings on your floor with tape and see how it looks.

Well, if 1.15m is sufficient, then just do it that way. When building a house, you have to find pros and cons everywhere and find an optimal compromise for yourself. You still have to bend down when putting things in, but in a different way. I always sort the laundry on the floor anyway, and then it is naturally lifted from the floor up into the machine. But it is not as uncomfortable as squeezing it in that low. We had that before. And when taking it out, I have a stool that I put underneath and then the basket goes on it. Then it is super easy to put the heavy, wet laundry in and lift the basket up. Or the wet laundry goes straight to the freezer on the right.
