220 m² for a semi-detached house? Enough space

I would also say: if the budget allows, plan for a basement to house the building services and to sink the infamous guest room below, and/or without much additional cost give a few degrees more roof pitch to force a usable (storage space/"studio"=guest) attic room there. Then the rooms on the ground floor and upper floor can even be designed very generously. From the house itself, I see no problems here. The garden will be quite cozy, but the south-west orientation seems to fit, so: why not?

I would definitely want to build with a basement here as well. In addition, large dormers to retain living space in the roof.

Isn't that extremely small even by urban standards?

No, it only becomes extremely small under 170m².

You have to keep in mind that you still need two parking spaces.

That is regulated differently from municipality to municipality; maybe only one parking space is necessary, maybe even none.

What about parking spaces?

The original poster still owes us an answer.

At least 3m clearance areas to the house on the street side and on one side.

You don’t need a 3m clearance to the street unless it is a private road and the owner forbids approaching, or there is a development plan.

or someone here can remember the name.

He already answered:

A two-story semi-detached house with a 30-degree pitched roof is desired.

Is that your wish? Is that fixed? Is that permissible? Is there leeway? Is there a development plan? What exactly was approved? Is the neighbor confirmed? Is/Will the green area be a private path? How many houses are accessed through it?

No, it becomes extremely small below 170m².

This is regulated differently from municipality to municipality; maybe only one parking space is necessary, maybe none at all.

The answer is still owed to the OP.

You don’t need a 3m setback to the street, unless it is a private road and the owner forbids approaching it or there is a development plan.

Is that your wish? Is it fixed? Is it permitted? Is there room for maneuver? Is there a development plan? What exactly was approved? Is the neighbor fixed? Is/will the green area be a private path? How many houses will be accessed through it?

1. Parking space or garage not mandatory.
But since I will build without a basement, I will build a large garage.
The city also allows this.

2. Desired by the city: 2.5 stories.
The shape of the house and the facade are prescribed.
I am attaching a photo.
The roof is also prescribed as shown in the photo.
An offer for the house in this form is available.
A package with general contractor for 295 thousand without painting and flooring work.

AND I THANK EVERYONE FOR THEIR CONTRIBUTION!!!
IT REALLY IS FUN HERE

PS: I have now bought the plot.
The path, i.e. the green area, will be "gifted" to us by the city.
They will lay the lines up to the plot there.
That would also be included.
The cadastral surveying office will also take care of surveying and the soil report.

Then a lot is already predetermined. Is the price including the plot? Or does the semi-detached house alone cost 295,000. Which KfW? Controlled residential ventilation? Can you have the floor plan changed? We are good at helping with that.

House built stone by stone NF standard. I can change the floor plan as I like, remove walls, add walls. So he said energy saving ordinance standard, but we didn’t go into that any further. What he probably meant by that I will clarify. The conversation with the architect is still pending. That was just preliminary information. 295 thousand is just the bare house without walls and floor coverings. I have opened a new thread, if you would be so kind as to look there and give your opinion. I have also uploaded an architect’s plan there.
