Thanks for the feedback
On the topic of pipe dreams:
It really was a concept where I was quite aware that it would not be feasible for me as is. And the folder P will probably get quite full.
What surprises me though is the price estimation. As I said, I was aware that it wouldn’t be realizable at that price. However, that it was estimated at 1.5 million was unexpected for me. I really have to re-interview my sources/contacts to see if they deceived themselves in their estimation/conclusion.
Thanks for pointing out the gross error!
On the topic of heating, I have the following considerations:
First, the heating demand:
As far as I could find out, the heat demand for a passive house is 15kW/m² per year; we simply double the value and say 30kW/m².
One question here: is this a realistic value in practice?
If we calculate with 160m² of heated area, that means 4800kW heating output per year.
Cost for purchase and installation of infrared heating: €8000
Cost for purchase and installation of air-water heat pump: €12500
Operating costs of air-water heat pump per year €150-200 (experience from a comparable single-family house in the family)
Regarding operating costs of infrared heating panels:
The keyword here is “electricity costs”
So, for electricity – Tiwag:
Cost per kWh 7.376 cents/kWh
however, the charges from Tinetz are added, so the final price per kWh is about 14 cents/kWh.
That results in running costs for the infrared heating of about €670.
That makes a break-even point at about 8-9 years if I have not miscalculated.
Now, with the photovoltaic system combined with good insulation (low heat loss), decentralized ventilation system (low energy loss during ventilation) and home automation that raises the room temperature according to certain rules when there is electricity surplus from the photovoltaic system thus allowing “overheating” of the standard room temperature, I hope to shift the break-even point a bit further.
Good insulation will be done regardless of heating system. Home automation is also desired; overheating the rooms is feasible with relatively little effort without Z-Z-Wave and KNX
Yes, the green is the stairs (sorry, I forgot to mention that).
The floor plan measures 2m x 2.135m.
I hardly found any useful design guidelines for stairs on the internet. But what I did find was a description with these measurements.
Too small?
There is space for that in the entrance area of the stairwell in the basement. The width between the stairwell and the wall is 1.8m. A wardrobe requires between 40cm - 60cm depth, depending on how the jackets and shoes are stored. That results in a passage of 1.2-1.4m.
That should be sufficient, right?
One more note:
Some shoes and jackets will be stored in the utility room, as the entrance through the garage leads through this room.
Both.
That means there needs to be space for hobbies; about 15m² would suffice roughly. However, since no attic or other storage spaces are planned, the room should be somewhat larger to create some storage space.
Somewhere the Christmas baubles have to be stored if there is no Christmas tree in the house.
Great statement
Hits the nail on the head
I googled that
Looks interesting, but I haven’t dealt with it much – however, I can definitely see similarities.
Do I understand you correctly that you mean the “putting together” with the neighbor here?
There are indeed already talks with neighbors. For example, the garage should be adjacent to the neighbor’s garage.
Also, earthworks and adjustments in the outdoor area will presumably be handled together.
Nice that you registered here. I think there are still many unrealistic pipe dreams that will end up in folder P by the time the first groundbreaking takes place.

Is the green area supposed to be the stairs? Seems too small to me.

Where are coats, shoes, bags supposed to go? No space for a wardrobe

What happens in the hobby room? Placeholder or really necessary
Both.

A house is a container for the life of the people who live in it. Habits, longings, attitudes, tasks, social attachment and connection, aesthetic sense, body awareness, and health

How would the neighboring insertion of this building look?
