Floor plan design: Single-family house with basement; 560 sqm plot

Comparison sketch is now attached, the black line indicates the ridge (or gable strip in #1). You will also find the other suitable ground floor in the attachment.

There is no gable there, you probably mean the stepped edge of the ridge offset.

We had planned the layout as follows:

[*] Basement: workshop, storage, utility room, technical room
[*] Ground floor: guest room/office, bathroom (shower and toilet), pantry, kitchen, dining and living room
[*] Upper floor: child 1, child 2, parents, bathroom

How does this relate to the previously quoted paragraph?

What we are still missing is the puzzle piece for the transition in form and orientation of the house on the plot. A few thoughts, detached from all designs: Of course, the main garden would be the right part of the plot (south side), so the arrangement of the children’s rooms would be towards the southeast, bathroom and parents’ room then rather depend on the arrangement of the wet rooms? On the ground floor, kitchen ideally with access to the garden and short paths from the entrance. That would roughly correspond to a mirroring of the open plan from the current design and then rotated by 90° in the UZS - although an L-shape for living room, kitchen and dining area would also be conceivable, similar to the first design.

The building form and its integration into the property are not a “still missing puzzle piece,” but a foundation.
Floor plans can be mirrored, but as described, rotated the sun would rise in the old north on the plan. Unfortunately, due to the tilt of the earth’s axis, this does not result in a linear shift of the sun’s path by six hours.

Our current understanding, at least for the design from #29 (image 1) is: The manifold for the BKA and underfloor heating is placed on each floor in the niche of the 24 cm wall facing the corridor.

The naïve thinking of intentionally building a thick wall just to weaken it for an HKV niche is funny (but unfortunately only that). The same applies to the continuation

The idea behind this was: In the realization of the controlled residential ventilation, initial rough calculations show it is more economical to build one brick higher (including whatever follows on top) than 75 mm ventilation pipes in the element ceiling with increased steel and concrete requirements and other technical execution. [ / ] Space for a decentralized ventilation unit is also available, if a central ventilation unit is not aimed for. From there, the underfloor heating for all rooms is easy to reach and to install. If now two at least 160 mm spiral pipes for controlled residential ventilation, about 4 well insulated 40 mm MSVR risers for BKA and underfloor heating, one downpipe, water, electricity, network and co. are installed, the shaft quickly gets full.

Suggestions and criticism are welcome.

They can only very limitedly cure a confused planning.

1. Take a sharp axe and free house and garage from their rigid connection to each other;
2. a. replace the struggling planner with a capable one;
2. b. stop leading the planner with half-knowledge gimmicks.

Oops! I find the ridge direction sensible, but explain the load-bearing wall and the bay windows to me. They will be two stories and therefore look quite unusual with the roof orientation. Biolek calls it "interesting," which does not necessarily mean successful.

decentralized UV

What is that?

at least for the design from #29 (Image 1): The HKV for the BKA and underfloor heating is placed on each floor in the niche of the 24 cm wall facing the corridor. There is also space for a decentralized UV if no central UV is aimed for. From there, the underfloor heating for all rooms is easily accessible and installable. If you now install at least two 160 mm spiral ducts for controlled residential ventilation, about 4 well-insulated 40 mm MSVR risers for BKA and underfloor heating, a drainpipe, water, electricity, network, and so on, the shaft quickly fills up. But yes, the shaft here is already large relative to the house, although the size also strongly depends on the technical equipment.

The idea behind it was: When realizing the controlled residential ventilation, it is cheaper according to initial rough calculations to build one stone higher (including what follows on it) than to install 75 mm ventilation pipes in the element ceiling with increased steel and concrete demand and other technical execution.

I would leave the technical planning aside for now. You’re not planning a mansion with west and east wings where you have to think about necessary rooms being additionally heated by decentralized heating units.
First comes the floor plan, then the technology. Otherwise, you get tangled.

Based on these thoughts @everyone (please correct me if something here is totally off): What arrangement possibilities (shape and orientation; also considering the option to omit the pantry) arise taking room and space requirements into account? Or can the current design even be redesigned so that it meets these needs?

Again: your room program is standard, and the house is standard except for the roof orientation combined with the bay windows.

We had the same criticism. Better to have more space for the children and make the parents’ bedroom minimally larger with space for wardrobe meters.

Such a bay window simply defines the walls, otherwise, the room would have too many corners.

Besides groceries, the intention was also to store regularly used kitchen appliances in the pantry (we have quite a few of those).

I bet those many kitchen appliances fit into a tall cabinet, possibly two.

The conclusion is: The floor plan is really not suitable for the plot.

By the way, it already existed on April 26 in #23 – very creative architect.

Comparison of #17 vs. #29 or #29 vs. #1?

I don’t even look at those because of the view from the living space to the nearby property boundary.

Maybe it would be an option to work together on a rough design that we can present to the architect as a "reference"?

You’re funny. That can be done, but keep in mind: he gets paid, we don’t.

A few thoughts, detached from all designs: As a main garden, of course, the right part of the property is suitable (south side), so the arrangement would be

This thought is my top priority: stand on the property, spend time, get to know every corner and mark where you’d like to sit, where you want to look, and where not. Then harmonize the ideas with the shadow casting, and you get a sketch of where the terrace or garage is best placed.
With the thought of where you want to access the terrace daily, what you like and love, the location you grant the children or yourself, a floor grows. And whether there is space for a pantry or not results from the more important rooms. If there is space for a pantry, the kitchen can be a bit smaller; if not, you plan for two tall cabinets.

What is this?

UV = sub-distribution. Decentralized -> not as "one unit" in the technical room, but for example one for each floor.

I would leave the technical planning aside for now. You are not planning a manor house with west and east wings, where you have to consider that necessary rooms are heated by decentralized heating devices. First comes the floor plan, then the technology. You will get confused.

Also here: your room program is standard, and the house is standard except for the roof orientation combined with the bay windows.

Such a bay window just defines the walls, because otherwise there would be too many corners in the room.

With the consideration of from where you want to access the terrace daily, what you like and love, which location you grant the children or yourself, a story grows.

Thanks for the explanation! We tried to pick up the ideas from the forum here. We focused on how we want to use the rooms, what the window views are, and how the circulation paths are. After visiting the plot again, we printed the plot on A3 and sketched first drafts with tracing paper. Strangely, as laymen, we got along best with the platform staircase, although one often reads that it consumes a lot of space. We could not accommodate a double garage combined with a simple building shape, therefore we reduced it to a single garage with a carport. If anyone has a better idea, feel free to share! After some back and forth, we had the hand sketches drawn in CAD by a colleague so that it can be discussed better here (no architect drew it!).

In short: Attached are two variants, whereby the floor plan is the same and only mirrored. We would be very happy about constructive criticism!

therefore the reduction to a single garage with carport.

Can the two required parking spaces be used independently of each other? If this is not the case, the captive parking space is often not recognized.

Can the two requested parking spaces be used independently of each other? If this is not the case, the trapped parking space is often not recognized.

The garage can only be used for one vehicle, theoretically two vehicles can fit side by side in the carport (5.3m at the back, 5.7m at the front). If the house is rotated a bit, the parking space width increases to 5.7m at the back and 6.4m at the front. Thus, the parking spaces can be used independently of each other.

We are currently considering how to proceed with the architect, so any feedback here would help us. , , Your suggestions were a great help. Perhaps you could take another look at the sketches above (#45) to see if we are on the right track?
