Floor plan holiday home Tuscany - 175 sqm on a moderate slope

I'm not a floor plan expert, but a toilet next to the kitchen is absolutely out of the question. Because of that, the kitchen/dining area feels like a corridor. Also, you fall straight into the house without a proper entrance area. I also find the staircase situation to the upper floor dreadful.

The floor plan would be a no-go for me. At least for a self-used property.

You are asking about prices in the wrong place here. We are in Germany and know prices from Germany – also due to the regulations in Germany. In Germany, you couldn’t build the house for that budget.
You have to ask around in Italian forums.

Thanks for the floor plan criticism. The staircase seems to be an aspect that caught your eye quickly.

Thanks also for the hint regarding prices. I will do some further research. To some extent, I also have to trust the architect that this project is feasible. The budget was communicated early and repeatedly. I’m curious about the first offers.

2.5m height difference in the area of the house. Your budget is not sufficient for that. The development already costs 100k. Please rotate your plot with north at the top.

Here is the plan oriented to the north:

Do you have a photo with the view? Show it and say in which direction it was taken.

that is approximately towards the northeast

I have shifted the house a bit. There is only a 10% slope. The access reduced by 50%. The house about 3 m higher. Red alternatively the driveway without 15% incline. Although in Tuscany 15% should not be a problem. Or does it snow there too?

although the northeast orientation probably protects somewhat against extremes

Yes and no. Of course, a north orientation protects. But anyone who has spent a summer vacation in the south (Italy, Spain, Greece, or elsewhere) appreciates outdoor areas that do not get any sun at all. And in the north, the sun does shine, for example, the midday sun.

The plan is to level the area at the house.

Hm. It makes sense here to create a holiday apartment on the side in the basement instead of some additional studio that you reach via a spiral staircase in the south. Yes, for one person the view is wonderful. But one also has to consider the overall situation.

On the other hand, without children there is only limited foot traffic.

But you are hindering yourselves as well. Houses from the '60s ('70s, '80s) often have a similar situation with the gallery and air space. However, not fully furnished, but in a separate area, so that the staircase is free. The toilet next to the kitchen was also criticized. At first glance, I wouldn't have minded because of the sliding door/hall buffer, but I also find it strange and unpleasant when the toilet and pantry share the hallway. *I miss something typical for the region in the planning. By that, I don't mean the exterior appearance, but rather the weather conditions as well as the terrain and holiday home usage. But maybe I'm overcomplicating it mentally. Nevertheless, certain characteristics have their background, for example, an air conditioning system is more or less a must. That’s also what you use for heating. No too large windows and if so, plan architectural shading walls/protrusions. Use the terrain slope for cool rooms and/or holiday apartment. With one hectare of land, ensure storage space for tractor and larger garden equipment. With a pool and the north orientation, you are already on a good path. I also like the separation of the guest room, even if you have to go through the chill area again. I wouldn’t forget that as host you might have to take care of cleaning the guest room, and for that reason, I would plan a laundry room upstairs. But whether anyone would access a roof terrace in 40/50 degree heat over a south-facing staircase, I don’t believe that. For that money, I would rather build a greenhouse for the lemon trees.
