I’m venturing into this part of the forum to share our floor plan for discussion. I’m hoping for constructive feedback and ideas in case improvements would be advisable.

We want a bright house of about 160-170 sqm (1700-1830 sq ft). We would prefer an open staircase design, but it should not interfere with the floor plan. The flat roof dormer is more than just a nice-to-have... 🙂

Overall, we like the current floor plan very much, but since we are building novices, we would like to go over it with you experts to identify any possible issues. As we haven’t signed the contract with the general contractor yet, there are unfortunately no detailed dimensions available. The furnishing in the kitchen, bathroom, and living area is not yet fixed, so please don’t focus too much on those!

Orientation: the street and entrance are on the north side, terrace faces southwest.

Garage, carport: garage or carport (6x9 m (20x30 ft) – position and storage room next to or behind garage not fixed yet – orientation on plot either lengthwise or widthwise)
Utility garden, greenhouse: no
Further wishes / special features / daily routine, also reasons for decisions:
  • Seating window on upper floor (bay window) – to hopefully bring plenty of light into the hallway and provide a nice view
  • Open staircase (straight or with landing, no preference)
  • Kitchen without direct line of sight from living area
  • Office preferably with garden access

House design
Origin of the design: original floor plan from Gussek House “Zypressenallee,” adapted to our needs and wishes by a general contractor’s planner

What do you like most and why? We like the layout and orientation of the ground floor, with sightlines from the entrance area

What do you like least and why? Uncertainty whether the kitchen is too tight; arrangement options for living room (sofa, piano!, bioethanol fireplace?) – possibly remove the middle square window in the living area on the ground floor in favor of more space for furniture?

Price estimate from architect/planner: 600,000 EUR (including garage, additional construction costs)
Personal price limit for house including equipment: 600,000 EUR
Preferred heating system: air-to-water heat pump

If you have to give up on certain details or extras:
- Can give up: staircase, 10 sqm (110 sq ft) of living space
- Cannot give up: bay window on upper floor (I just really like this nesting box)

Why is the design as it is now? For example:
The desire for a bay window with reading window and open architecture was implemented, combining examples from various magazines...

What is the most important/basic question about the floor plan in 130 characters?

I agree with Katja: these are all very high-end staircase designs… don’t get me wrong, I think they are all great. But they are basically the icing on the cake of luxury features, which require even more square meters (square feet) to really make an impact. Maybe it’s worth first recognizing the advantageous basics of a staircase????

Ok, I understand.
I was already aware that these stairs are among the more expensive options. However, I’m not sure if the cost will be closer to 10k or over 15k. For now, we have budgeted around 10-12k for the stairs. That doesn’t mean they can’t be simpler, though.

We will go through all the information again and see if and how we can get the best value out of it.

Then that roughly fits.
It’s hard for readers to understand if money is tight everywhere but you don’t consider investing more in living space.
So I need to ask again, sorry if I missed it: You have 600k for the garage, house, and additional costs. How is that divided? With this floor plan, roughly estimated, you have 11.60m x 8.40m x 80% (due to the walls) which equals 156 sqm (square meters) x 3000 = 468k. If you increase to 11.6 x 9.4, using the same calculation, you get about 523k with the difference that the layout of the living area and kitchen improves immediately. Are 80k for the garage and additional costs not sufficient?

The garage could also be added later or not at all.
My priority would be the house for the people, not the house for the car.
If the budget is tight, you could leave a bathroom in a rough state (my brother did this, lived with only one bathroom for 3 years and kept the door closed).
Living space in the house is more important and cannot be changed later.

As a reader, it’s hard to understand why, if there’s a tight budget everywhere, the money wouldn’t go into more living space instead.

With this floor plan, you’re roughly at 11.60m x 8.40m x 80% (due to the walls), which is about 156 sqm (1,680 sq ft) x 3000 = 468k. If you go up to 11.6 x 9.4, with the same calculation, that comes to around 523k, with the difference that the layout of the living area and kitchen would immediately be more comfortable. Won’t 80k for the garage and additional costs be enough?

The total budget is currently 600k (excluding the land) and is allocated as follows:
- 470k for the house (this is how it was estimated)
- 30k buffer
- 50k for additional construction costs
- 50k for kitchen and landscaping

The garage would cost an additional 50k. We plan to include it in the building permit application but will likely construct it later, possibly just a carport. We were offered an extra 10 sqm (108 sq ft) of living space for 17k EUR.

It would be interesting to know exactly what is included in the ancillary construction costs if the landscaping is already included with the kitchen. For us, it was mainly fees. These were considerable but not $50K.
Otherwise, prevention is definitely better than dealing with problems later.
Maybe you should have your financial plan prepared much more precisely soon.
What would be really unfortunate is ending up with $40K left over afterward while the dining area is actually too small.
