Hello everyone,
My name is Konstantin, and we will be building a house for ourselves and our children (currently 1, increasing to 3 in the next few years) in early 2017.
I have been following this forum for a while and am always grateful for your tips on all aspects of house construction. I have already been able to use many ideas for our project. Thank you all!
Attached is our floor plan (created with a friend who is an architect).
This floor plan has been optimized several times and we are quite happy with it.
Since this is a major investment that should be well planned and prepared, we would like to hear your opinions on the floor plan to avoid possible mistakes or to incorporate new ideas.
We look forward to your feedback.
I have included images of the ground floor, upper floor, 3D house model, and the plot.

j.bautsch16 Dec 2016 07:30The walk-in closet immediately caught my attention as well. I would extend the right wall of the closet and design it as a passageway to the bedroom. This way, you don’t have to walk through a narrow corridor to get to the bed. However, I also agree with bieber0815 that the layout is somewhat awkward.

Thank you very much for the initial feedback.
Hello Steffen, thank you very much.
You are right, on top of the 500k there is quite a bit more:
+ 5,000 euros architect (is a friend)
+ Additional construction costs
+ 35,000 euros KNX
+ 20,000 euros borehole heat pump
+ 15,000 euros controlled ventilation system
+ 2,000 euros water softening system
+ 20,000 euros contingency for bathroom and stairs
Hello Bieber, thank you.
The office is intentionally designed that way; that’s where I earn the money for all this luxury.
Why convoluted? We deliberately tried to keep it as clear as possible.
Hello j.bautsch, thank you.
We deliberately did not want that for the following reasons:
1. We would then have to pass through two doors about 2 meters (6.5 feet) apart (like an airlock), which would be a real nuisance, especially at night when going to the bathroom.
2. Dust migration... Clothing produces a lot of dust and lint, especially when dressing or undressing. I don’t want to constantly spread those particles throughout the house by passing through the dressing room. They should stay in the dressing room (door closed).
Thank you very much for the initial feedback.

Nice design... I like it. 500k including additional construction costs and architect? That’s too tight. The house alone ~500k plus 50k architect (HOAI) plus 50k additional construction costs is probably more realistic. KNX easily adds 30–35k additional to the electrical costs. Borehole heat pump, controlled ventilation system, and water softening system will also total around 50k. Many architects don’t charge that high... so be careful. We just went through all of this. 225 sqm (including attic), garage 470k plus architect plus 150k additional construction costs (KNX, controlled ventilation, and so on).
Regards, Steffen

The overall layout seems a bit convoluted to me. In many places, a smaller rectangle (cube) has been added within a larger one to provide certain functions (kitchen-pantry, bedroom-dressing room, office-utility room...). This leads to somewhat “odd” (?) circulation paths. Often you end up walking through narrow corridors.
Example:
- Guest to guest bathroom
- Resident from couch to toilet
- Homeowner to their bed
- Back and forth to office
- Guests to office (meeting room?)
The more I think about it, I would replan. Make the office smaller (but only you know how many guests come to meetings at once), improve office access, generally smoothen corners and edges.

+ 5,000 Euro architect fee (he is a friend)That hardly seems enough for the structural engineer, right? He must be a very good friend... he’s probably taking quite a loss on this.

Steffen8016 Dec 2016 10:20The time required for the detailed design is already significant, and is he really going to do all of that for free? A friendly price would be 20,000 EUR... normally around 50,000 EUR. But 5,000 EUR is just ridiculous.

I just spoke with him, and he confirmed that 5,000 euros is completely sufficient for his work (planning, structural engineering, and building permit application). He is not doing construction management; my mother is taking care of that (she has years of experience as a construction manager).

Bieber081516 Dec 2016 11:19I would modify the dressing room/bedroom as follows: remove the dressing area, move the door to the bedroom downward on the plan. Position the bed away from the window toward the left on the plan. In this large room, you then have more than 5 m (16 feet) of wardrobe wall at the top of the plan, as well as plenty of space to arrange furniture freely (freestanding bed, dresser under the window, etc.).
On the ground floor, I had misunderstood the entrance situation; the path to the office actually seems fine to me.
What kind of staircase are you planning? Perhaps a very open staircase supported on one side by the wall could be an option here.
