House design
Who is the plan from: A finished, standard solid house from the shelf of a construction company
(No advertising/links allowed, so I roughly drew it; please forgive mistakes)

What do you especially like? Why?: Open kitchen -> pleasant. Office on ground floor -> practical and also some storage possible (e.g. drinks). Several windows facing south -> nicely bright.

What don't you like? Why?: Entrance directly by the stairs -> dirt? Parking space takes up a lot of space.

Price estimate according to architect/designer: approx. €200,000 without major extras (still waiting for a detailed breakdown)

Personal price limit for the house, incl. equipment: I would rather not go much higher with the price for the house (without incidental costs, without garden)

Preferred heating technology: I would like to hear your opinions. Find an air-to-water heat pump interesting. Underfloor heating or classic radiators, I don’t know. Central or decentralized house ventilation also not fixed yet.

If you have to do without, which details/extensions
-can you do without: -
-can you not do without: Garden area facing south

Why did the design turn out the way it is now? e.g.
Standard design from the planner? It is a standard design that was liked.
Corresponding/which wishes were implemented by the architect? -
What makes it particularly good or bad in your eyes? Bad is rather the relatively large east garden. There is a fear that it gets dark quickly there in the afternoon. Bad is possibly the long way to the front door.

What is the most important/basic question about the floor plan summarized in 130 characters?

What is your opinion on the house size related to the plot? Is the house position and orientation well chosen? Is the space sufficient to turn cars well? Is there a good possibility for both cars to leave the property first?
Do you have tips to realize the largest possible south garden (preferably other narrow houses)?

Thanks and best regards,
ChronoMax

The model house does not fit like this because the entrance is far too far away. Can you please draw the building envelope on the property?

Hello ypg,
Here is the building window:

Cars usually have a turning circle of about 11-13m - my great-great-grandparents therefore had a turntable in the courtyard of their townhouse to be able to turn the carriages around ..

Turntable to be able to turn the carriages

I had also thought of such a turntable with a diameter of 4 m ;) (but electric)

Price estimate according to architect/planner: approx. €200,000 without major extras (still waiting for a detailed breakdown)

Phew, that's very ambitious. Do you already have a fixed general contractor? Is the plot already yours? Have you been to a bank yet?

Preferred heating technology: I would like to hear your opinions on that. I find an air-to-water heat pump interesting. Underfloor heating or classic radiators, I don’t know. Central or decentralized house ventilation is also not fixed yet.

Oh, those are also things that cost money. What about gas?

There is a concern that it gets dark there quickly in the afternoon.

It never gets dark anywhere in the garden except after sunset. One has to differentiate between terrace location and light inside the house. That can also come from another side. How was it? Are there fields to the east?

Do you have tips for realizing the largest possible south-facing garden (preferably other narrow houses)?

What about your general contractor? According to the budget, it will almost certainly be a model house with hardly any changes, which is also okay. Does he offer other models?

I’ll be honest: you calculate €2000 per sqm of living space plus painter, floors, exterior and incidental building costs.
So what is missing from your general contractor that you don’t have on the list?
