Plot of land 371 sqm, are the expectations realistic?

our development plan is pretty "loose"

I would say "so-so". After all, you may only build on a maximum of 35 percent, so roughly 65% remain for (front) garden. Here it is 40% (which is more than sufficient).

We built as large as possible (no development plan, but restrictive building laws in Bavaria that unfortunately make densification rather unattractive). The dimensions are 12.5m x 7.3m. The garden will still be around 70sqm; lacking a green thumb, that is enough for us. Apart from a grill with a seating area, a paddling pool, and a sandbox, we don't need anything else. But of course, that is very individual. We are building without a basement, so we definitely need the space in the house.

Yes, that is true, it is always individual, but it is quite good to read experiences so you don't get stuck on just one opinion.

how large you build is always a budget question anyway

as large as we are allowed, is definitely too much. There are only three of us

yes, I wanted to say that what we are allowed is already too much anyway, hence my casual tone

the terrace should be placed in the west, since a south-facing terrace would border the parking lots on the private road.

I had already found many floor plans, but the requirements have changed due to corona.

for 4 months I have been working at the dining table in the home office, so the new house should definitely be able to accommodate an office on the ground floor, as there will be more home office work in the future. Before that, it was not an issue at all..

however, on about 150 sqm without the whole thing feeling too cramped

so kind of the jack of all trades.. oops:

how big it is then also always a budget question

Just build as big as your needs are. Everyone does that if they can and are allowed to.
Why should you build more? Or don't you have to watch the costs?

But we also have to watch the costs.

I have to say that many people in our circle of friends are building or have built, and now everyone tells each other what they would do differently if they were to build again. And everyone agrees not to build too small. Therefore, we got a bit unsettled about what is really necessary and what is nice to have for us.

But we are interested in how others with a similar plot decided. Since our friends all have 500sqm+ of land area...

everyone tells you what they would do differently if you were to build again.

Maybe they didn't think enough beforehand, but just chose a standard floor plan? Presumably, you will never be 100% satisfied, but many "mistakes" can be avoided if you think things through thoroughly... And listen to the advice and tips from the forum
