Plot for semi-detached house - How large should it be?

Hello everyone,

I have a question or rather a discussion

How much land area is needed for a semi-detached house or one half of a semi-detached house? How many square meters should it be to live "comfortably"?

The reason behind this is that finally the vacant lot opposite our property is going to be developed. I found the final lot sizes, into which it was divided, interesting: One half of a semi-detached house gets just under 230m². Isn't that way too little? For the half-house, at least another 60m² will probably be taken up, two parking spaces plus a terrace also need to be added.

I am very curious to see how it all will look in the end – so far I just can't imagine what it will look like. Above all, this is a rural area where there is basically enough space – in cities or also in village centers I can well imagine such dense construction, but out here in the countryside? Is it comfortable to live there, does a "house feeling" develop, or is it more like living in an apartment?

What do you think? After all, it is very affordable. 230m² of land plus 150m² house for half a million. A bargain.

A semi-detached house only saves a side building setback per half - and not even completely, because the windowless side in the floor plan requires compensatory measures, which can generate a handful of extra square meters in total.

That means, in principle, there is a difference from the requirement of a detached single-family house mainly in the plot width - since the floor area ratio factor is not affected (it is usually set equally high for D or E/D plots as for their E neighbors).

Semi-detached house plots therefore mainly arise when two narrow plots are created by a division. The question of convenience is, in my opinion, already answered: inherently lower, since one would almost always voluntarily build a less "elongated" cross-section of the floor plan.

230 sqm of plot area, in my opinion, is borderline and only sufficient for two and a half stories (regardless of whether it is a recessed or pitched roof); with fewer stories, the house becomes a sardine can.

People who buy something like this are "partly to blame" for such things being dared to be sold at all - especially at princely prices.

As stated at the time in an advertisement:
Terraced house 119 sqm living area with optimal plot size of 108 sqm.
Near Munich, something like that can happen.

So we have 466 sqm for our semi-detached house - and it shouldn't be less, I also want to have a garden. I would have preferred an even bigger one where more trees can fit, but we are lucky to have that much for a semi-detached house, most plots are significantly smaller.

As I said, I’m curious to see how it will look in the end. The access road is on the west side, meaning the terrace would have to face that side. But it will be rather tight there; in the end, the terrace would have to extend almost to the property boundary just to fit a table on it. In front of that, ideally a gabion fence, and the cozy feeling will quickly set in... But where is there still room for bicycles on such a property? Sandbox & play equipment for the children? Rotary clothesline? There’s no basement, either...

The plot is just as big as the little piece of garden that is finished with us. Since there is still a house on it
