Open Kitchen, Cooking Island: Open, preferably with a cooking island but not essential
Number of Dining Seats: 6-8
Fireplace: Not planned initially, possibly reconsidered due to KFW funding changes
Balcony, Roof Terrace: Potentially a small “roof terrace” above the apartment terrace would be nice, but not planned due to budget (great view)
Garage, Carport: There is an existing garage (built 1995) in an inconvenient location, which will remain for now
Additional Wishes / Special Features / Daily Routine, including reasons for decisions
The plot is heavily built up, so we have tried to identify spots with good views, which involved a lot of planning on my part. Good views are towards northeast and west
House Design
Who designed the plans:
Architect and do-it-yourself: Mainly my own design; the architect made changes, some of which we did not like (e.g., U-shaped staircase, arrangement of rooms difficult), so currently it is essentially a drawing based on my drafts with useful improvements from the architect
What do you particularly like? Why?
Staircase, integration of WC on the upper floor, loft door to the open space as a connection to the “stairwell.”
Entrance to the utility room to be placed under the stairs on the ground floor, shifting the wall of the apartment unit accordingly.
Children’s rooms are the same size, space-saving staircase to the attic (amazing view from there), use of attic as playroom and possibly guest accommodation.
Living room ceiling height increased to 2.70m (8 ft 10 in) planned on the upper floor.
What do you dislike? Why?
Entrance to the utility room still needs to be placed under the stairs on the ground floor, requiring adjustment to the apartment’s wall.
Windows generally need revision; in the living room facing west, possibly an “imitation corner window” (with support pillar) to maximize the view.
The kitchen window facing northeast should definitely be a seating window.
Price Estimate According to Architect/Planner:
Including groundwork, €540,000 (approximately $600,000), but originally planned with KFW 55 energy standard, which we missed submitting on time. Now we need to reconsider, as we actually wanted KFW 40 standard for the two residential units. 😡
Personal Price Limit for the House, Including Fixtures:
€540,000 would be ideal; preliminary estimates from contractors roughly match this.
Preferred Heating Technology: Planned heat pump with underfloor heating
If you have to give up on which details / expansions
-could you give up:[/I]
Attic later, glass door/loft door to living room later, no planned lift-and-slide doors or other fancy features
-cannot give up:
Wooden flooring, sufficient windows, wheelchair accessibility on the ground floor
Why is the design the way it is now?
Long iteration process on my part, partly inspired by Pinterest, but overall the external envelope is quite predetermined
What is the most important/fundamental question about the floor plan summarized in 130 characters?
Is there anything that doesn’t work? Have we missed anything? How about the window layout (still to be revised)? Does it make sense as the architect suggested? We even want to remove some windows (e.g., in the bedroom).

Ground floor
Here are my dimensioned floor plans. I swapped the utility room and the bathroom, which I think works well, but furnishing the bedroom is quite challenging. I decided against a small intermediate hallway to maintain accessibility. It might be possible to add one later, or perhaps use a room divider.
I would prefer to move the wall between the utility room and bathroom on the ground floor further to the right, but that would make furnishing the living area more difficult. I used existing furniture as reference points for the current layout.

The toilet looks so tiny. It feels like sitting inside a closet. What are the interior dimensions? It’s quite small! But we thought it’s better than having no toilet on that floor at all. My suggestion to place it on the left exterior wall was rejected by the architect, who argued that the study would then just turn into a storage room.
The software is called Architouch 3D. I once paid 20€ for a month and now I believe I can work on a project indefinitely.

Quick question off-topic: How much did the demolition cost?According to the quote, 28,000 euros, although we have not received the invoice yet. A comparative quote was at 52,000 euros.I certainly don’t want to be disrespectful, but I find the ensuite bathroom in the granny flat quite unfortunate.
What happens if the unit is rented out to someone else in the future?
For a two-room apartment of this size, I would prefer the toilet to be accessible from the hallway, so guests don’t have to walk through the bedroom. Ideally, the bedroom should also be large enough to fit a double bed without major compromises.
I feel the space in front of the stairs in the open-plan area is somewhat wasted, considering the size of the WC and the adjacent room.
Upstairs, I would personally allocate more space for the children’s rooms.
This means making the bedroom smaller, but as always, opinions differ on that... 😉
