Good evening!
Keywords to start: townhouse with pitched roof, KfW40+ energy standard, geothermal heating with ground probe, photovoltaic system at least 10 kWp + 5 kWh battery storage, living basement with external stairs and laundry room + basement room for a granny flat, converted attic. Turnkey price 580,000€ including basement and carport.
This year we will be building a house with a granny flat for renting out to the parents-in-law just outside Hamburg. The floor plan is a preliminary draft created by ourselves. We hope to get valuable ideas and suggestions from you to optimize the layout, since we have become too close to the project. We are not yet fully convinced by the townhouse design, as it feels a bit impersonal. However, the lack of sloped ceilings and the large attic space provided by the pitched roof are appealing. We are considering adding a veranda facing the street and window shutters to give some character. The interior will be designed in a rustic country house style.
We already have a quote, which we plan to accept. However, the floor plan and possibly the house type may still be adjusted.
We have attached screenshots of the development plan, infrastructure plan, house graphic, floor plan, cross-section, and garden plan.
We look forward to your ideas and thank you in advance for your time!
Development Plan / Restrictions
Plot size: 774 sqm (8,331 sq ft)
Slope: No
Plot ratio: 0.25
Floor space index: Unknown
Building envelope, building line, and boundary: See development plan screenshot

Style, roof form, building type: No fixed specification. Townhouse has the big advantage of no sloped ceilings upstairs and large attic space if built with pitched roof rather than hip or pyramid roof.
Basement, stories: Living basement, ground floor, first floor, and converted attic
Number of occupants, ages: 2 adults in early 30s and 1 child; we plan to have at least 3 children.
Space requirements on ground floor and first floor:
Main residence: At least 55 sqm (592 sq ft) living/dining/kitchen + hall + shower bathroom ~70 sqm (753 sq ft)
First floor: 3 children’s bedrooms each at least 13 sqm (140 sq ft) + bathroom 13 sqm (140 sq ft) + corridor ~62 sqm (667 sq ft)
Granny flat: At least 75 sqm (807 sq ft), 2 bedrooms of 13 sqm (140 sq ft) and 10 sqm (108 sq ft), living/dining/kitchen about 35 sqm (377 sq ft), one bathroom at least 6 sqm (65 sq ft), and a guest toilet of 2 sqm (22 sq ft)
Office: Family use or home office? Both
Overnight guests per year: 20
Open or closed layout: Rather closed; floor-level windows only on first floor facing west and northwest (due to street in southwest, none facing south)
Conservative or modern construction: Rustic
Open kitchen, kitchen island: Yes
Number of dining seats: 10 with extendable table
Fireplace: Yes, but planned for later due to cost
Music/speaker wall: No
Balcony, roof terrace: Not desired
Garage, carport: Carport
Kitchen garden, greenhouse: “Self-sufficiency” garden and chickens
Two terraces facing southwest and northwest.
House Design
Who designed it: Us, the owners.
What do you particularly like? Why? The granny flat only has access via the laundry room and its own basement room accessed by external stairs. A lot of usable space was gained on a small footprint through the basement and pitched roof. We like the two terraces which provide afternoon and evening sun.
What don’t you like? Why? “Square, practical, good.” A townhouse feels a bit impersonal, but 1.5-story design offers too little space in the attic and the sloped walls are inconvenient.
Price estimate according to architect/planner: Turnkey 580,000€ according to the quote, including living basement, geothermal heating with ground probe, photovoltaic 10 kWp + 5 kWh battery, KfW 40+
Personal price limit including equipment: 600,000€
Preferred heating system: Geothermal heat pump with ground probe
If you had to give up something, which details or expansions
Could you give up: Kitchen island, possibly the pitched roof but rather reluctantly
Cannot give up: No basement is a no-go
Why is the design as it is?
Standard design by planner? Own design
What is the most important/fundamental question about the floor plan in 130 characters?
We hope to receive valuable ideas and suggestions for optimizing the floor plan.

I’m asking, where is north? Is there a section in the development plan about that? How did you come up with the idea of designing a house like this? I don’t see a roof eave height of 3.5 m (11.5 ft) anywhere. You should start over. Or better yet, have someone who knows what they’re doing plan it. 🤨
That becomes less of an issue with one less floor. :p I’m quoting myself here: the eave height is 6 m (19.7 ft), please disregard the part about the eave height.
What does the text section say about parking spaces and garages / carports?

How is the basement staircase supposed to exit into the ground floor? I would just be walking into the sloped living-kitchen wall. That doesn’t really solve anything now, since the staircases seem to be changed here like weather vanes anyway.
