Unfortunately, I was no longer able to edit my previous post, so here it is again, including the floor plans and with better image quality.

Good day.
We plan to build a single-family house on a 610 sqm (6566 sq ft) plot in a new development area. We have already made some considerations. By now, we have been able to refine and clarify our wishes. At this point, we are wondering whether we might have overlooked something or if there are any suggestions for improvement.

Development Plan
  • Site coverage ratio 0.3
  • Floor area ratio 0.8
  • Number of parking spaces: 2
  • Number of storeys: 1
  • Brick masonry
  • Roof style: gable roof with 45-degree pitch

Client Requirements / Wishes
  • Family with two children
  • Living space around 200 sqm (2153 sq ft)
  • Target energy efficiency class KfW-40 EE (hence the thick exterior walls)
  • Room requirements on the ground floor: kitchen + pantry, open-plan living and dining area, guest toilet, utility room with garden access, study/guest room
  • Room requirements on the upper floor: 3 bedrooms, 2 bathrooms
  • Two children's rooms approximately the same size, each at least 16 sqm (172 sq ft)
  • Fireplace, preferably U-shaped, serving as a room divider between dining and living areas
  • Technical room for heating system, heat pump with hot water storage, photovoltaic system with battery storage, and ventilation system with heat recovery
  • Double garage including a workbench
  • No basement due to a high groundwater level
  • Void space to improve lighting in the ground floor and for the central corridor on the upper floor, preferably a closed void (to increase privacy in the living area and avoid cooking smells in the upper floor sleeping areas)
  • Laundry chute from the master bathroom leading to the utility room
  • Current Challenge
  • Feasibility of the ceiling construction in the living and dining area with the walls above on the upper floor (question for the structural engineers)

We would like to thank you in advance for your active participation and support.

How old are the children that they don’t want to retreat to their rooms or prefer sitting in the dark? I don’t know any 12-year-old who finds an open space above the dining table so cool that they never want to see sunlight themselves.

And especially when the main living area is as bright as a theatre stage, it becomes even more noticeable when you enter a northeast-facing room.

Or is there another building regulation requirement you know of that mandates the 5m?

It is at least stated in some state building codes (LBOs). And unless otherwise specified, it applies. It serves to protect other road users, so why should this be considered less important in some places?

Oh, this is such a pleasant tone here with you! ... the positive feedback from some forum members really helps! Thank you for that.

Well, let’s say this: you either don’t respond to criticism at all or you downplay it. That is also a form of communication, but one you won’t benefit from. Ask yourself whether you want to communicate here or if you’re able to accept genuine criticism. You wouldn’t be the first who just wants to present their house here.

What puzzles me is that almost all professional publications manage without the much-praised dimension chains here. So is there really no expert audience present here?

You’re not in a specialist forum here, but in a forum for non-professionals. And precisely the demand for missing dimension chains (if that is the case) should be noteworthy: without them, hardly anything can be seriously assessed. Overall, only processes and orientation can be considered, but not dimensions, which naturally play a significant role in floor plan drafts.

Since I am new here, I am very curious whether there will be any serious and well-founded contributions.

Apart from the fact that no floor plans have yet been posted that can be viewed without downloading, the measurements would likely be missing anyway. I like the views except for the northwest one. The question is: why isn’t the garage located in the northwest?

Is it allowed to have the garage there? Usually, it must be at least 5 m (16 feet) away from the street almost everywhere.
If the gate can be opened electrically when approaching, it usually is allowed.

Should we read that between the lines as if you wouldn’t appreciate valuable warnings?

What puzzles me, however, is that almost all technical publications manage perfectly well without the much-praised measurement chains mentioned here.

Please name such technical publications (note: no links!), I’m eager to learn more.

It’s an open secret that only about seventeen thousand of my posts are actually useful, and the ENTIRE REST (also a good four hundred twenty) are really just rants against inspectors and real estate agents *shame*; unfortunately, from @Escroda, known as the king of serious, well-founded contributions, there are no posts here anymore, and also none from @kaho674. Most recently, we sadly lost @hampshire. Well, the air is getting thinner. But in a free country, it’s up to you to decide whether you want to offer the remaining community members a bowl of measurements or not.

- We have a window-to-net floor area ratio of 27.86%, while the Lower Saxony Building Code requires at least 12.5%, and DIN EN 17037:2019-03 considers 20 - 25% optimal daylighting. Additionally, both rooms receive light from two different cardinal directions. I’m happy to reconsider that point. The open spatial concept was one of the most important aspects of our design. Unfortunately, it’s not possible to orient everything to the south in one plan.

As far as I know, there is no corresponding provision in Lower Saxony. Here, 0.5H applies.

why is the garage not in the NW?

- Garage location: Based on optimizing the plot use in relation to the sun’s path. The goal is to create the largest possible garden area facing south. With the garage on the east side, we would only get proper evening sunlight in a garden strip at least 6.6m (22 feet) wide, and the kitchen would be closer to the neighboring building.

What else is there to say? You argue using DIN standards on window areas, but for you, the most important part of the house is an open space that is basically just an architectural gimmick, previously reserved for architecturally well-designed villas – that north-facing light is always cool and on winter days with bad weather produces rather gray-blue daylight… doesn’t matter. For you, it is more important to have a bright, light-filled dining and master bedroom area than to provide the children’s work and living spaces with psychologically beneficial lighting conditions.

I had a northeast-facing room and, except in the height of summer with good weather, I always had to use artificial light to work or play in the room.

For me, the priorities are just not right.
