Hello everyone,

After more than six years of searching, we will soon be able to purchase a plot of land, so it’s time to advance the planning.

Since we are still undecided whether to build with an architect or a developer, we started drawing ourselves and have been diligently browsing internet forums like this one. The floor plans below are the result, thanks to SketchUp.

I hope we understand the floor area ratio correctly, meaning the basement is not included. Otherwise, we have a problem...

Development plan/restrictions
Plot size 15.6 x 29.95 m = 436 sqm (51.2 x 98.3 ft = 4,692 sq ft)
Slope no
Site coverage ratio 0.4 = 174.4 sqm (1,878 sq ft)
Floor area ratio 0.8 = 348.8 sqm (3,753 sq ft)
Building envelope, building line and boundary 12 m depth (39 ft)
Setbacks 3 m (10 ft) on right and left
Number of parking spaces only in front of the garage planned
Number of storeys 2 full storeys
Roof type Gable roof 42 degrees
Style brick + Wienerberger Poroton T7 P 36.5
Orientation garden facing east-northeast
Maximum height restrictions 10 m (33 ft) high
Other requirements finished floor level at least 30 cm (12 inches) above reference mark

Client requirements
Style, roof shape, building type gable roof is mandatory
Basement, number of storeys 2 full
Number and ages of occupants 6 (37, 36, 6, 4, 2, 0)
Space requirements on ground and upper floors (see plan)
Office: family use or home office? both
Guests sleeping per year the attic provides enough space
Open or closed architecture
Traditional or modern design it will be a smart home with KNX, photovoltaic system, heat pump, possibly battery storage…
Open kitchen, kitchen island open kitchen
Number of dining seats 6
Fireplace no
Music/stereo wall I was thinking of multi-room audio, i.e. one ceiling speaker per room
Balcony, roof terrace no
Garage, carport garage
Utility garden, greenhouse later
Additional wishes/particulars/daily routine, also reasons why certain things are required or excluded The house should be divisible in 25 years, hence the staircase placement. There is a kitchen shown on the upper floor, but it will only be relevant in 25 years. I roughly marked the ventilation system, indicating where ceiling or wall outlets might be and where ducts lead to the upper floors. The two offices are important. The master bedroom on the ground floor is future-proof. Everyone gets old!

House design
Who designed the plan: us amateurs
What do you like most? Why? four equally sized children’s rooms
What do you like least? Why? the upstairs hallway might be somewhat dark
Price estimate according to architect/planner: if only we knew
Personal price limit for the house including fittings: 400 + building allowance
Preferred heating technology: ground-source heat pump

If you have to give up features or extensions
- what can you do without: I hope we don’t have to
- what can you not do without: we definitely want to keep the base dimensions and the basement is a must, but we may have to save on components.

Why is the design like it is now? 4 children’s rooms, two offices, ground floor master bedroom, divisibility in 25 years…
What do you think makes it particularly good or bad? that’s what we want to know from you

What is the most important/basic question about the floor plan in 130 characters?
What would you do differently and why?

Nice, but you can still plan to include a window!

@Yvonne: What issues did you notice with the shower? Was it also the size?

Of course. A shower should be rectangular, ideally 1.00 x 1.60 meters (3.3 x 5.3 feet)...
I might consider swapping the bathroom with the office. That way, visitors don’t pass right by the window. You have to see how it fits. I wouldn’t oversize the bathroom now either.

Why? Light comes through the glass sliding door, and the rest is handled by the controlled ventilation system.
That’s way better than a “cubicle,” especially one made of plastic that needs rinsing.

Well, I have to admit, personally I wouldn’t install the glass sliding door but would replace it with a proper door. Otherwise, as a guest, you might feel quite exposed, don’t you?

An accessible shower measures 150x150 cm (59x59 inches). Our "niche" with 140x149 cm (55x59 inches) is quite tight but should be sufficient. That is why it is planned like this on the ground floor.
It is not necessary on the upper floor, of course.
Regarding the proposed partial WC design, I dislike that the toilet would not be accessible or, judging by the dimensions of the "cubicle," could not be converted to be accessible in the future. In our plan, that would not be an issue. However, I agree with you that the guest WC should have a window.

I don’t understand. Do you have to build to accessibility standards? I wasn’t aware of that until now.
