Hello,
we have been following this forum for some time and have already incorporated many ideas into our floor plan design. Now we're starting to get serious and want to obtain cost estimates. Changes to the plan are still possible.

The plan was created by a structural engineer based on our wishes.
We would appreciate suggestions and constructive criticism.

Development Plan / Restrictions
Plot size: 849 sqm (approx. NE-SW - so from bottom to top: about 30 meters (approx. 98 feet, average, slightly diagonal), from left to right about 26 meters (approx. 85 feet)

Slope: No

Site coverage ratio: 0.3
Floor area ratio: 0.6

Building envelope, building line and boundary: Yes, there is one, about 3 meters (approx. 10 feet) to the NE and SW. On the other two sides, boundary development is possible.

Number of parking spaces: Attic + 2 parking spaces in front
Number of floors: two full stories, no basement

Roof type: Shed roof (mono-pitch) with 6.6-degree slope

Style: Modern

Orientation: Southwest

Maximum heights / limits: (specified above sea level) - approx. 11.5 meters (approx. 38 feet)
Additional requirements: No flat roofs, minimum roof pitch 5 degrees, for two full stories a maximum roof pitch of 35 degrees for gable roofs.


Homeowner Requirements
Style, roof type, building type: Shed roof (mono-pitch), modern, clean lines

Basement, floors: two full stories, no basement

Number of residents, ages: Currently three (34, 33, 3) - possibility for a second child is open.

Space requirements on ground floor and upper floor: Probably less than initially planned...

Office: Family use or home office?: An office is desired for general household activities, but working from home is not mandatory.

Overnight guests per year: about 15

Open or closed architecture: Open. Definitely open.

Conservative or modern construction: Modern

Open kitchen, kitchen island: Yes. - Not yet shown in the plan; we have currently designed a peninsula with five tall cabinets behind it (in a niche).

Number of dining seats: 6

Fireplace: Yes

Music / stereo wall: Not necessary.

Balcony, roof terrace: No

Garage, carport: Maybe self-built later, but already planned.

Utility garden, greenhouse: No.

Additional wishes / special features / daily routine, also reasons why certain things are desired or not: We work shift schedules. It would be good if one can get up without waking the other. Also, we want a "buffer zone" between the children's bedrooms and the master bedroom to allow sleeping during the day.

House Design
Planner: Independent structural engineer (commissioned by us)

What do you particularly like? Why?: Open living space, straight staircase, gallery, no "uninviting" stairwell, corner window in the living room, spacious ground floor.

What do you dislike? Why?: Layout of the upper floor (storage room as a last resort?), second door in the bathroom, general window arrangement.

Cost estimate according to architect/planner: 350,000 - 400,000 euros
Personal budget limit for the house, including fittings: 400,000 euros
Preferred heating technology: Air-to-water heat pump with underfloor heating and fireplace - NO ventilation system!

If you have to give up anything, on which details / extensions can you compromise: build smaller if necessary; straight staircase
On which details / extensions can you not compromise: gallery, fireplace, office, children’s bedrooms no smaller than 15 sqm (approx. 161 sq ft)

Why is the design the way it is now? - ? Because it was planned around the straight staircase
Standard design from the planner? - No

Which wishes were implemented by the architect? - Almost all.

A mix of many examples from various magazines... - Yes

What is the most important / fundamental question about the floor plan, summarized in 130 characters?
How do you see the price range, what are your honest opinions about the floor plan in general? Ways to reduce the size?

As an additional note, the house should be positioned on the plot as shown in the attachment.

It’s best to also upload the drawings as image files; that will help bring the discussion to life.

Straight, single-flight stairs take up a lot of space and expand the floor plan. The layout as planned barely works, but it can’t be made any smaller.

Simply swap the parents' bedroom and the dressing room; then the "changing room" can be removed, and the second door to the bathroom can be eliminated as well.
At first glance, I don’t see any further design flaws. The hallway on the ground floor is huge – which doesn’t have to be a bad thing if you’re planning an elegant entrance area, but to me, it seems rather plain and dull, just like the living area. Maybe the housewife has a good eye for interior design.
The elephant has already made his remarks about the staircase – I agree.

...Well, it also depends a bit on what expectations you have... if you reduce the house by one meter (3 feet 3 inches) on the lower level, it still works... the children's rooms become a bit smaller... you give up the gallery and instead of nearly 60 square meters (650 square feet) for living/dining/kitchen, you end up with "only" 50 square meters (540 square feet). But you save about 20-25 square meters (215-270 square feet) on the total house... or am I missing something?
