Single-family house floor plan, 2 stories without a basement

Hello everyone,

we are currently planning to build a single-family house and have put together the following floor plan with Home Design 3D (however, the PDF print function always crashes, so here are the screenshots).

The house:
- no basement
- 2 full floors
- utility room and guest shower on the ground floor
- the utility room should accommodate: photovoltaic system with storage, all main connections, electrical panel, ventilation system, washing machine, dryer, and a small sink
- study on the ground floor
- pantry under the stairs
- bedroom and 2 children's rooms on the upper floor
- sports/storage room on the upper floor
- attic as storage space

What do you think?

Pain points from my perspective, where I have the most questions:
- Is the size of the utility room sufficient?
- Is the guest bathroom size adequate, or have I planned the pipes to be too small?

PS: my first post, I have only been here for a short time, so please forgive me if something "essential" is missing

What do you think

You have found the subforum, so you will also find the questionnaire for constructive criticism. Please fill it out (!) and preferably upload the site plan etc., and so on.

All right, second attempt:

Development plan/restrictions
Size of the plot: 401 sqm
Slope slight incline: no
Floor space index: 0.4
Floor area ratio: 2
Building window, building line and boundary: 15.6m width by 15m length, with 3m left and right remaining undeveloped each (except with garage)
Edge development:
Number of parking spaces: 3
Number of floors: 2
Roof shape: gable roof
Style direction
Orientation: garden facing south
max. eaves height: 6.6m
max. ridge height: 13.1m

Client requirements
Style, roof shape, building type: gable roof
Basement, floors: no basement and 2 full floors
Number of people, age: 2 adults <35 and 2 children <5
Space requirement on ground floor, upper floor:
Office: yes, on ground floor
Guest sleeping ca. 30 (on sofa bed in study)
Open or closed architecture
Conservative or modern construction: modern construction – solid construction
Open kitchen, cooking island: YES
Number of dining seats: 4-6 (but not at the cooking island)
Fireplace: yes
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: garage opposite 2, or at least a storage shed
Utility garden, greenhouse: nothing large
Further wishes/special features/daily routine, including reasons why this or that should or should not be:
- a sports room or also for storage on the upper floor
- parquet everywhere except bathroom/laundry room/toilet
- sliding windows on the ground floor
- attic not converted but insulated
- outdoor area done by ourselves

House design
Who designed it: myself with help from Home Design 3D
What do you particularly like? Why?: straight staircase lengthwise, layout of living, cooking and dining areas
What do you not like? Why?:
- narrow bathroom on the upper floor → it is narrow but a compromise so that wet rooms are stacked and the rest is well divided
- laundry room → all technology must fit in (photovoltaic and storage, ventilation system, etc.) and washing machine/dryer and a small sink, no idea how far apart things need to be and what exact sizes will be
Price estimate according to architect/planner:
Personal price limit for the house, including equipment: 500k EUR
Favored heating technology: heat pump (air-to-water)

If you have to do without, which details/extensions
- you can do without: if necessary the sports room (although the bottleneck is more likely the ground floor than the upper floor)
- you cannot do without: shower on the ground floor and study

Why did the design turn out the way it did? e.g.
Standard design from planner? = No
A mix of many examples from various magazines. = rather own creation and a few ideas from other floor plans
What makes it particularly good or bad in your eyes? = good, because quite compact and efficient use of space (6 rooms with appropriate sizes e.g. children’s room > 14 sqm)

Question:
- am I overlooking bottlenecks that appear feasible in the plan but won’t work in reality, e.g. because pipes need more space?
- is the laundry room layout okay and will I fit everything mentioned there?

Thanks in advance

Hello and welcome! I think that’s not so bad for a first attempt. On the ground floor, we probably see the Neo from Fingerhaus. Unfortunately, the upper floor doesn’t fit so smoothly with it. You don’t want to pay for all those narrow rooms – believe me, you would regret it at some point. Basically, you should clarify 3 questions beforehand: 1. The budget. Roughly estimated, about 175 sqm x €3000 (basic equipment) = €525K. That already puts us over, and we haven’t paid anything else except the house. If I read the technical equipment and other wishes, the €3K/sqm probably won’t be enough, I’m afraid. So the red pen will probably have to come out. 2. I assume the front door is facing north? 3. With 3 parking spaces, you should start on this relatively small plot with the placement of the house and the parking spaces before the floor plan.

Personal price limit for the house, including fittings: 500kEUR

Should the ancillary building costs be included in that? Is this supposed to be built by a general contractor? Around 3000€/sqm. With your stated fittings more like 3200€/sqm.

e.g. because pipes require more space?

Things like missing technology will be corrected and hopefully changed by the architect. Unfortunately, it will probably remain as is, since the client is king nowadays and does not want to be disappointed when told that many things are actually not that nice. Therefore, the joints and roughness will be accepted.

I overlook bottlenecks that seem to work in the floor plan but won't function in reality

I think the design has no added value for its size compared to its smaller siblings, except of course many rooms. However, building big is no art, unless you cannot afford it. The rooms are almost all very narrow, so not well shaped. The doors almost all open in the wrong directions or have the wrong hinges. Moreover, they are poorly positioned so that you cannot hide cabinets behind them. In the children’s and sports rooms, you bump into the cabinets. What bothers me personally right away are the narrow windows and the long corridor next to the stairs. Nothing will happen there. Opposite the utility room door, the corridor gets tight (a ladder or similar could get stuck). Is it clear whether those are terrace doors or windows? I wouldn’t plan one-meter-wide windows as double-winged. That doesn’t fit the size of the house either. It is quite wide anyway. Otherwise, the windows are placed very arbitrarily. Or? What is that square in the vestibule?

, thanks for the feedback. 1.) we need to take another look at that 2.) the front door is on the north 3.) we want to build the house and the garage in a line 5m from the boundary (thus the 3 parking spaces would easily fit, one in front of each garage and one in front of the house. This way the garden would be (5+11.5=16.5, leaving 9.2m garden length and 15.6m garden width). The pure garden would thus be 143 sqm in size (excluding the additional side strips), which would be completely sufficient for us.
