Additional wishes / special features / daily routine, including reasons why certain things are or are not wanted:
- Carport adjacent to utility room
- Utility room adjacent to kitchen
- Kitchen semi-open to living/dining area
- Possibility to create 2 separate living units, for example through a staircase at the main entrance and a vestibule in the hallway (for when the children grow up, rental, etc.)


House Design
Who designed it: architect
What do you particularly like? Why? Not really anything
What do you dislike? Why? Room layout is totally illogical, for example living room in the northeast, utility room in the southwest and far from the carport, 170m² (1,829 sq ft) instead of 150m² (1,615 sq ft)
Cost estimate according to architect/planner: -
Personal price limit for house, including fittings: €275,000
Preferred heating technology: geothermal with horizontal trench collector

If you had to give up something, which details/features
- can you give up: cooking island, office on ground floor, laundry room
- cannot give up: semi-open living / kitchen area, possibility to create 2 separate living units

Why does the design look the way it does? For example:
Standard design from the planner? No, but the planner showed us a similar floor plan during discussions
Which of your wishes were implemented by the architect? four walls
What do you think makes it particularly good or bad? They hardly considered our wishes and the house is way too large

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

We took our own floor plan to two builders who offered it as is. We were not really satisfied and wanted a professional involved. Unfortunately, the architect’s drawing was a real disappointment. Issues I notice as a layperson seem to be overlooked or ignored. Shouldn’t our wishes be feasible within 150m² (1,615 sq ft)? The floor plan problem is holding us back a lot. The architect took almost a month to send us this poor draft. Structural calculations, energy regulations, etc., are waiting to move forward, and I don’t know what to do.

The house is number 25 (blue in the center) on the site plan.

Best regards

André

Painting and plastering work is completely missing, right? That can easily add up to $50,000 or more.

No, there are just many individual items in a single-family house and I haven’t listed all of them in detail. All walls are finished as standard with Q2 plaster.

What about small details like window sills, etc.?


I’m not going to start copying and pasting all the complete quotes now.

Oh, and we also have KNX, which usually increases lighting requirements. How does it look here? That can easily add another $10,000.

In summary, there is only one thing to say – this won’t work. You’re already short by $100,000 with just the standard equipment...


Alright, please close and delete this thread. I’m always happy to discuss, but this is going nowhere. I wonder how people in my circle manage to build their house for similar budgets without it leaking inside ¯\_( ツ )_/¯.

Feel free to share a few more opinions. There are really people in this forum who are well-versed in the subject of house construction and costs. You mention 50€/m² (square meter) for tiles. Is that net or gross? For example, we are currently calculating 130€/m² (net).

Sorry to say this, but the budget just won’t work. Of course, you don’t want to hear that, but everyone here will tell you the same. $1500 per square meter (approximately $140 per square foot) is never going to be enough, especially with the features you're planning like KNX and so on. Welcome to 2019. €2000 per square meter (approximately $185 per square foot) is actually already the absolute minimum.

As I said, I have no problem with other opinions and am open to being convinced otherwise. However, I don’t want to have to defend the cost of each item, especially when these are common prices in this area...

€50 net, the standard for most is around €30. €130? What are you planning to install? When my parents renovated three years ago, they ended up paying €50 gross, and that was already for something quite good...

You wrote that you don’t know what is missing.
Then you are told what usually is missing.
No one said you have to publish the offer item by item.

It should only make you think that everyone has pointed out so far:

The 2-meter (6.5-foot) line is missing on the upper floor plans.
Draw your existing or desired furniture everywhere to scale. Consider traffic routes, open doors, and that someone sits on the chair at the table.

Look at floor plans. Neither a gable roof nor two children's bedrooms are unusual.

I would choose a narrow building shape and move it as far north as possible.

Something like this, for example? Living area facing south, and instead of an extra door to the kitchen downstairs, a shower for the bathroom. Upstairs, two equally sized children’s rooms on the left, extend the third gable where the open office is and put the bathroom there. On the right, bedroom and office. Does that work?
