ᐅ Floor Plan Design and Orientation of an Urban Villa with Two Residential Units

Hello,

I plan to build a city villa with two residential units with Dennert.
The location is Neustadt, Marburg-Biedenkopf district, parcel 20, plot 16/2.
You can view it in the Hessen geodata system. The property would be split almost equally in half. It is not yet decided which half we will use ourselves; the younger sister will take the other half.
I’m unsure how to position the house so that, for example, a balcony above the garage could be used, possibly facing south-southwest.
Could you possibly help me with this?

The property is listed on Immobilienscout24 with Scout-ID: 70642775 (just enter the Scout ID on Google).

I know that without a building permit/planning permission it may not help much, but the property has not been purchased yet. See my related question in Land for Building, Contracts, Building Law Tips.

The neighboring development is set back 3 meters (10 feet) from the property, but there is an old house directly on the property boundary. Therefore, I would suggest planning the building plot at least 3 meters (10 feet) away from the property line.

Building Permit/Restrictions
Property size: divided into 1962 by 900 (units not specified)
Slope: none
Site coverage ratio
Floor space index
Building envelope, building line and boundary: possibly 3 meters (10 feet) from the road
Edge construction: garage yes
Orientation: this is the question, what is best?
Maximum heights/limits: neighboring houses have eaves heights over 7 meters (23 feet)
No building permit/planning permission available yet

Client Requirements
City villa
No basement
Parents, 60 and 63 years old, on the ground floor; sister, 37, with child 7 and second child 17 (who does not live there regularly) on the upper floor
Approximately 90 square meters (970 square feet) per residential unit
Ground floor definitely with a guest room
Very open architecture
Modern construction
Open kitchen, kitchen island: both yes
Number of dining seats: 8 on ground floor, 6 on upper floor
Balcony, roof terrace: possibly a balcony above the double garage
Garage, carport: double garage with door to the utility room

House Design
Planning by:
- Do-it-Yourself
Personal budget for house including fittings: 400,000
Preferred heating technology: air-to-water heat pump, eligible for BAFA funding, with ventilation system and photovoltaic system with storage

If you had to give up something, which details/upgrades
- you could give up: KfW40+ standard if it doesn’t make sense, balcony above garage, garage itself if necessary, possibly sourcing sanitary fixtures independently
- you could not give up:

Why was the design chosen as it is? For example, what makes it particularly good or bad in your eyes? Discussed with parents and sister about their wishes.

What is the most important/fundamental question about the floor plan summarized in 130 characters?

Whether it is feasible and whether the location on the property is okay. Also, suggestions for improvements and possibly help to properly save the floor plan in a file format, not Paint (sorry, I’m not good at this).

It would be great if someone here could help me!

The proposed layout of the plot doesn’t really make sense to me; I can’t tell where the neighbors or the street are located. If a neighboring house is built right on the property line, I would expect there to be a setback agreement, meaning the previous owner probably registered an obligation in the land registry to maintain a 6m (20 feet) distance between the two houses on their side alone. I wouldn’t commit to any specific building material at this stage. I don’t quite understand the project: you show a two-family house that’s the size of a single-family villa, and you mention one sister living there and another sister on the other half of the property. Where do you fit into this arrangement yourself?
The references to the locations on the plot are almost commendable—but I don’t have time to follow them up.

Ah, okay, there is a street under the property (more like a lane) and a street to the left. I thought I was not allowed to post links, so this is the explanation. There is no neighboring house in close proximity to the property.

I am planning for my parents and the older sister. The younger sister will get the other half of the plot. There is nothing for me. I already built a house 8 years ago.

That is correct – we only provide free advice here, and there isn’t time to go look for plots ourselves. Screenshots of cadastral maps or aerial images would be more helpful.

Um, I didn’t really get any planning experience from the floor plans :-(

Please add dimensions and scaled furniture to the floor plan.

A drawing with measurements corresponding to the text would be helpful. I only see rectangles… and yes, those are supposed to be rooms. But honestly, I can’t make much sense of it.

Try marking the existing trees with a green colored pencil, the street in gray, and draw some lines with measurements for the property boundaries. And don’t forget to indicate north.
