Hello,

I have been reading along for some time now and finally dare to share a floor plan here.
First, here is the list of questions:

Zoning Plan / Restrictions

Site plan with blue building structures, green areas and trees


Plot size: 576 sqm (6,200 sq ft)
Slope: Yes, slight. According to the site plan, the top "right" corner is at 295.4 meters (970 feet), lower at 293.88 meters (964 feet), left side goes from 295.17 meters (968 feet) to 293.43 meters (963 feet)
Floor area ratio: 0.3
Building envelope, building line and boundary: Applies to house number 16

Site plan of a building plot with parcels, building areas and street details.


Surrounding buildings
Number of parking spaces: 2
Number of stories: 2 full floors required, plus optional recessed floor (setback floor)
Roof type: Flat roof, max. 5° pitch
Maximum height/limits: Max. 10 m (33 ft) high
Additional requirements: Equipment (heat pump) must be integrated, not external. Maximum of 2 residential units. Specific exterior colors required, rainwater should infiltrate (soil report says this is unlikely). Roofs must be greened. No oil or gas heating allowed.

Client requirements
Style, roof type, building type: Actually, none specified.
Basement, floors: No basement, 2 floors.
Number of occupants, ages: 4 people — 2 adults, 2 children
Ground floor space needs: Daily life (living, kitchen, dining, technical room, guest room)
Upper floor: Family (2 children's rooms, master bedroom, separate bathrooms), home office
Office: Home office, second workspace for occasional use such as a work window sill for example in the bedroom
Guests per year: Currently few.
Open or closed architecture, conservative or modern style: Either is fine.
Open kitchen, kitchen island: We are still considering. Initial wish was separate pantry like in the floor plan. An island would be nice if space allows.
Number of dining seats: Normally 4, rarely up to 8.
Fireplace: None.
Music/stereo wall: Multi-room audio with central unit in technical room.
Balcony, roof terrace: Neither.
Garage, carport: 1 garage
Other wishes: Central vacuum system, laundry chute, smart home (KNX) (I am mostly doing this myself, yes, I am a certified electrician, can program, but will also get additional help)

House design
Who designed the plan:
- Planner from a construction company: Correct, with some input from us. Based on an existing plan.
Price estimate by architect/planner: approx. 485,000 € (euros) for the house, approx. 210,000 € for the plot including basic services (survey, soil report, etc.)
Personal price limit for the house including features: approx. 800,000–850,000 € (including land)
Preferred heating technology: Heat pump

If you had to give up, which details/extra features could you skip:
- Could skip:
- Cannot skip:

Why is the design like it is now? For example:
Standard design by the planner? Yes, with minor wishes from us (wall between study and child’s room 2, T-walls in bathrooms, porch roof, conservatory, pantry)
What do you find especially good or bad about it? So far it seems to fit; apart from possibly the pantry/dining room, we don’t see major issues yet. But that’s why I’m here now.

Floor plan of a house with rooms, furniture, outdoor area and dimension lines.

Floor plan of a single-family house: parent’s/children’s rooms, study, hallway, bathroom, garage.

Floor plan: green flat roof, conservatory above, garage on the left, VELUX windows in the center, dimension 10.96 m (36 ft).


Edit: The furniture shown in the floor plans can be safely ignored. Planners seem to like adding these.

Best regards
Ganneff

Please enlighten us. I have read about the “Robber” several times, what is that about?

I’m sorry you had to wait so long. I was typing the answer for almost half an hour when a mouse button (or Windows, who knows) malfunctioned and I had to rewrite everything from scratch because suddenly it was all gone:
@R.Hotzenplotz (1,610 posts, member since August 8, 2015, last seen October 10, 2018) tried to find out across numerous individual threads how to best build his approximately 220sqm (2,370 sq ft) “city villa,” if I recall correctly. His initial mistake was probably hiring a general contractor who was not really suited for realizing his very modern design; the contractor had an inadequate profile (happy to install traditional toggle switches, but reluctant towards technical and/or visual modernity) and also involved a frame builder for the first time in his project. This eventually led to an endless chain of minor disasters, during which the “Robber” apparently went through four construction experts (some recommended by the community) before withdrawing here out of genuine frustration. He deliberated so much about many details that he lost track of the current release status of the detailed plans, which resulted in the utility installer placing the house connection in the wrong basement room (correct in an earlier plan). The threshold to exit onto the laundry balcony turned into a major obstacle due to misunderstandings about its necessary and possible height; rainwater downpipes were boxed in because they were installed next to, not inside, the planned wall chases; the elaborately integrated mailbox cannot be accessed from the back for insulation reasons; the intended lawn tractor model was only able to fit through the front gate, but not also through the rear gate of the double drive-through garage, and much more.

May I ask what positives Fingerhaus highlights about their electrical installations?

Combined with the not exactly brightest construction consultants/advisors/architects, this resulted in a build that seemed like a prototype for training new construction experts.
There were actually no other construction consultants involved, only me here in the forum. The self-designed plan was already too advanced for an architect to save anything. And even construction supervisors or experts cannot intervene retroactively – by the time the third one was called in, the situation was clearly beyond saving. The pathologist knows everything, but too late.

May I ask what credit you are getting from Fingerhaus for the electrical work?

You’re always welcome to ask.
They deduct a "Finish Package 04," and in return, you get a preparation for outlet boxes and wiring pulls, which results in a reduction of about 12,000 euros (approximately $13,000). (This doesn’t come close to covering what I’m planning, but that’s to be expected. What’s removed is a very basic standard electrical setup, whereas what I’m planning is something different).

The standard electrical work is always quite basic, regardless of whose construction specification you look at.

How thick is a non-load-bearing interior wall then?

The question comes out of nowhere for me. What are you getting at?
11ant schrieb:

Electrical work is structurally such a load-bearing element, and within a turnkey house it’s such a minefield of warranty issues that the head of the legal department could retire just for not prohibiting it from sales.

I don’t quite understand what you mean exactly. Could you explain in which areas it might be difficult to separate warranty responsibilities when the electrical installation is done in a stud wall?

That @wiltshire doesn’t regret it, in my opinion, is not encouragement to try it yourself.

That’s true. It only shows that it can run smoothly and without stress. It should perhaps be added that I awarded the contracts myself (not a generally recommended approach) and made sure that the carpenters and electricians already knew each other from various projects and were well coordinated. For the carpenters, I purchased trade coordination. Their site manager proved to be very reliable and was significantly less expensive than site management services according to HOAI.
It is a path with risks that you can identify and evaluate. Essentially, it comes down to how much entrepreneurial spirit you bring to your own construction project. There is no “right” or “wrong” here, but rather “suitable” or “unsuitable” depending on the builder’s personality.
