Floor plan of a new multi-family house with 3 residential units, living area approx. 350 m²

I hope the development plan was reviewed thoroughly, because with such a project many problems can occur: - The mentioned eaves height - In many new development areas, a green roof is required for flat roofs (if that is the case, also consider the additional costs) - Hope 3 apartments are allowed (often limited to 2 residential units) - Pay attention to the floor area ratio (the terrace also counts, so be careful when choosing the size) - Sometimes 30% planting of the property is required. This could also be tight here. etc.

Thank you for these hints. Green roofing is required (for roof pitch under 10 degrees) and planned. The floor area ratio is 0.4. The development plan states: "The floor area ratio may be exceeded by up to 50% due to ancillary facilities (§ 19 Abs. 4 Baunutzungsverordnung)." Therefore, we see no problem in this respect. Regarding planting, the following applies: "At least 30% of the open spaces on the property must be planted with native, site-appropriate deciduous trees." Therefore, this does not refer to the total property area but to the open spaces, which should not be a problem.

Thank you for these notes. Green roofing is mandatory (for roof pitches under 10 degrees) and planned. The floor area ratio is 0.4. The development plan states: "The floor area ratio may be exceeded by up to 50% due to ancillary facilities (§ 19 para. 4 Federal Land Utilization Ordinance)." Therefore, we do not see any problem in this regard. Regarding planting, the following applies: "At least 30% of the open spaces on the property must be planted with native, site-appropriate deciduous shrubs." Therefore, this does not refer to the total plot area but to the open spaces, which should not be a problem.

Then it should definitely work out. Regarding the floor area ratio, please note that, for example, the terrace does not count as an ancillary facility to my knowledge. But it should be sufficient as long as the terrace is not planned to be too large. Garage/shed count as ancillary facilities, so that would not be a problem.

Yes, great. It is always very helpful when the site plan is included here. However, a site plan counts in its entirety (legend and drawing). It is required by the questionnaire, and I requested it in #6. Nothing came of that. Then one looks at the draft, asks where you are placing the 5 parking spaces, and you don’t respond.

I already answered this in the previous post. I do not yet have a site plan at the moment. My questions also relate to the floor plan design.

Because no one here wants to seriously discuss every crazy idea, pipe dream, or simulation house. You wouldn’t be the first. And sorry: about the budget, I’ll just say: Welcome to 2024!
You are also asked other questions that you do not address. I ask about supply and disposal, about the parking spaces, nothing comes from you on that. People discuss here, and if the original poster does not participate, replies with wrong information, keeps distant, or remains silent, then the discussion just doesn’t work.
Anyone planning by themselves should inform themselves beforehand.
The basic conditions must be correct, then the details follow!

I will address everything step by step. It takes a little while for me to answer everything; there are many more follow-up questions than I thought.

Regarding connections and discharges: this is considered in the current plan. Wastewater is bundled on the upper floor (through the floor structure and concrete ceiling) and connected to the wastewater sewer via the shower toilet and bathroom on the ground floor.

I assume they are also for the garbage?!
But again: where are the 4.5 parking spaces? If you place your shed on the boundary on each side, there is not much space left.
And that’s why we are currently dealing with a crazy idea – living space is often planned without parking space obligations.
Where is the accessibility?
Where is the technical room?

I have already addressed the points on parking spaces and garbage. To my knowledge, the apartment on the ground floor is barrier-free according to the Hessian building code. The technical room is marked in the plans on the ground floor. The previously shown separation in the sketch is, of course, only a room division and not a wall.

I do not have a site plan at the moment. My questions also relate to the floor plan design.

Both belong together. You can plan a great floor plan that then does not make sense on the plot, for example due to the orientations.

The parking spaces are laid out like this (see sketch). [IMG alt="1725005848134.png"]https://www.hausbau-forum.de/attachments/1725005848134-png.87476/[/IMG] As far as I understand, this is permitted. Of course, it still needs to be approved.

Enclosed parking spaces are almost never recognized.

Prisoned parking spaces are almost never recognized.

In my current residential building, it was approved that way, but it's not certain. At least it's the same building authority.
