House Design

Preferred heating system: Ground-source heat pump with ring trench collector, including passive cooling, controlled ventilation system

If you had to give up details / additions
- What you could give up: T-shaped bathroom solution
- What you cannot give up: Hi-fi living room, kitchen island, walk-in showers, double garage

Why is the design the way it is now?
I can’t do better (layman) :-D. Unfortunately, the architect couldn’t either (objectively speaking).

--------------------------------------------------------------------------------------------------------------------------------------------
Hello everyone,

Here are some SweetHome files again (the professionals will probably roll their eyes already), but with the difference that I probably spent more time on the design than usual for a layman’s draft.

About the ordeal:
I have an architect, but after 4 months of waiting, only disappointing results appeared on paper. Although I requested a fresh concept, the exterior dimensions were copied and the rest was made worse. A typical example of no time, rushed work combined with little talent.

Then I went to a construction company. Their design proposal—again from a female architect—was also catastrophic.

Then I lost trust in the profession and took matters into my own hands. It seems there are many bad apples among architects. I was somewhat confirmed in this by the fact that almost every architectural floor plan posted here in the forum gets heavily criticized (but I understand the reasons, thanks to the great forum members!).

About the house:
All development plan requirements have been met.
North is truly at the top of the plans with only a two-degree deviation.
There is a street to the north. South offers a nice view. East and west have plenty of distance to neighbors.

For you, the unmarked floor plans in the second post are probably the least confusing (but they are not completely up to date). The double garage is partly missing there.

Best regards, and I look forward to constructive suggestions!

I’m not sure what you’re trying to achieve with your question. However, it is clear here that you have already built the house:

Is that some kind of modular construction/big Lego blocks???

Thanks in advance, Katia!

A guest toilet without a window is always a bit of a pity. Would it be an option to swap the cloakroom and the toilet and open up the vestibule?

I can’t quite imagine what you mean yet. The passage to the garage has to remain. Would you then use a strip window?
K a t j a schrieb:

It feels like the kitchen and the lounge should be swapped so you can step directly from the kitchen onto the terrace. Only bad because of the pantry. But otherwise someone is always running in front of the TV. That’s really annoying, especially since you care so much about that. I would probably have the pantry accessible from the hallway and bite the bullet of having to walk 3m (10 feet) to get there.

Here too, I lack the creativity to see how to implement that. Where do I put the base cabinets if a large lift-and-slide door occupies the west wall?
How do I solve the drainage?
K a t j a schrieb:

Unfortunately, I don’t understand the location of the chimney. Is it in the middle of the room? It’s not, right?

No, it stands in front of the solid wall and is boxed in. The fireplace is in front of it. (See living room pictures 1 and 2.)
K a t j a schrieb:

What do you do with a sink in the garage? Won’t it freeze in winter?

The utility sink won’t freeze. The garage is planned with a U-value of 2.0 W/(m2K) (13.3 Btu/(hr·ft²·°F)). The roof above even has 1.0 W/(m2K) (6.7 Btu/(hr·ft²·°F))—same insulation as the house to avoid height differences.
It has a large garage door, but I think that shouldn’t be a problem.

Better leave the recessed doors in the guest room and child’s room 2 at the back. Otherwise, the corridor loses a lot of its aesthetics and cozy atmosphere. The other rooms don’t really benefit from it.

I pondered that for a long time as well! The space under the stairs (folded structure look) is intended to be used as a storage room/wardrobe. I found that a continuous alignment with the partition wall of the two rooms looks cleaner. Maybe I just couldn’t visualize that space well enough.
K a t j a schrieb:

Do you really need all those rooms under the garage? It’s tempting to incorporate them into the insulated envelope and place an office and bedroom there. In my opinion, there’s good potential for savings if that becomes an option.

I need a workshop (currently way too small)—25 m² (270 sq ft) would be preferable :-D. I also think you need a storage/pantry room.
In the garden-side “garage” in the basement, the lawnmower, bicycles, and some of my tools in cabinets will be stored.
Here again, walls with a U-value of 2.0 W/(m2K) (13.3 Btu/(hr·ft²·°F)).

Best regards

Yes, the shell is already built. However, almost all walls are drywall partitions. I can still make changes to all of these, or I can move or remove elements.
The exterior dimensions are fixed. My concern is the floor plan, which is why I titled it "Last Minute."
If this was not clear, I apologize.
I would like to clarify this again in the title, but I cannot find an option to edit it.

Yes, the structural shell is already completed. However, almost all the interior walls are drywall construction! I can still make changes to these. I can move things or leave them out. The exterior dimensions are fixed. My focus is on optimizing the floor plan, which is why the title says "Last Minute." If this wasn’t clear, I apologize.

Of course it’s “not clear,” because you never mentioned it anywhere. Instead, you referred to several architects who are no longer relevant here. Interior walls are visible, and what’s left to redesign when almost everything is already built?
I would never design a house with only one balcony connected to the open-plan living area. I probably would have criticized that and wasted our time unnecessarily.
I would have placed the open-plan living area on the ground floor and the bedrooms upstairs. I don’t see any benefit in making it impossible to access the garden from everyday living areas. After all, daily garden care during the growing season and using the lawn are part of everyday life. I would have created a small gallery upstairs for the nice view, possibly with a whirlpool on a balcony, but I prefer living close to the garden.
