Hello dear forum community,
I am probably still at a very early stage of my project. Well, at least the building plot is already secured.
At the moment, I am trying to design a floor plan that I could be happy with.
The house is planned as a single-family home including a double garage and an upstairs granny flat.
Optionally, it should be possible to convert the single-family home into two separate apartments without major structural changes, in case we decide to rent it out.
I would simply ask you to take a look and give me all the feedback you have—anything you don’t like or that I could improve.
Usually, you only build once in your life, so it should definitely be right.
I am grateful for every reaction from you.
Best regards,
Sebastian

Site coverage ratio: individual
Floor area ratio: 2.5 You misunderstood that. The floor area ratio is not the number of floors, but the factor by which the plot area is multiplied to calculate the maximum allowable living area. For example, floor area ratio “0.4” x 636 = 254.4 sqm (2729 sq ft). The site coverage ratio means the same for the building footprint, e.g., site coverage ratio “0.2” x 636 = 127.2 sqm (1370 sq ft). Recently, development plans more frequently specify only the site coverage ratio or the floor area ratio, since that is usually sufficient along with the maximum number of floors allowed.

Here is the exterior view. Your window lintels are positioned noticeably lower than the door lintels. That looks odd, and the view out of the windows is awkward as well ;-)
But—even though I see “lots of potential” in your floor plans—the consistency in the number of different window formats already appeals to me.
Dimension lines are, let’s say, “not your strongest point,” and it seems you haven’t dealt with construction tolerance dimensions yet.

The views are meant just to illustrate... the software simply allows it and makes working in 3D as well as in draft mode enjoyable 😉
Sebastian, the floor area ratio cannot be customized.
Although Bavaria is a bit different, if you describe the area as "rural," I doubt you are allowed to build that much floor area.
It’s best to check this with the floor area ratio and plot ratio before investing more effort.
Otherwise, the balcony could be better used by the basement apartment. An external connection between the master bedroom and children’s room is not practical.
If, for example, the doors in the basement apartment are repositioned first, it could actually become nice with a sunny balcony.
Other than that, I would generally suggest opening up the main house facing south.

Sebastian_LA13 May 2018 16:34Okay 🙂 So, I marked the south side incorrectly. The south is on the balcony side 🙂
I couldn’t find anything about the floor area ratio or similar.
I simply drew the plan according to my preferences.
I fully understand that an architect and structural engineer will have to review and revise everything.
Our development plan is from 1996, and there is a lot of new construction happening around us right now.
These new buildings do not fully comply with the development plan.
What I have already learned from the municipality is that I am allowed to build 2.5 stories high and that the roof ridge direction does not matter. I’m attaching the development plan here for you.
Please don’t judge me too harshly. I am a LAYPERSON trying to get help and advice through a forum like this. I will only build once in my life, and I want to make sure this huge investment is well spent and built according to my rough ideas.
Best regards

This is purely about the floor plan, and of course the windows and doors play a role in that 🙂

These new buildings are nothing like what the development plan specifies. Can you judge that yourself, or has the local authority already confirmed it?

What I have already learned from the municipality is that I am allowed to build up to 2.5 stories high. Did the official actually mention half stories? Legally, those don’t exist in building regulations. It also seems that roof extensions are not permitted on your lot (Zone II and not II+D).

You should definitely draw your property to scale (get a cadastral map and enlarge it or use Bayernatlas) and accurately transfer the building boundary lines. It appears your house won’t fit within the designated building area, so all your efforts might be in vain. Also note that the house must maintain at least a 3m (10 feet) setback from the property boundary.

Sebastian_LA13 May 2018 19:55The floor area ratio is 0.4
The plot ratio is 1.1
Our plot currently has a total area of 1790 m² (19257 sq ft), on which a house is already built.
This will later be divided into 636 m² (6845 sq ft) and 1154 m² (12422 sq ft).
Can I use the current 1790 m² (19257 sq ft) as the basis for my calculations, or do I have to use the later divided plot areas?
