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?

Most people will do as Kaho's grandmother does and stay in the familiar rooms as long as possible.
We have not planned for sleeping on the ground floor.
Nevertheless, there are no thresholds, wide doors, and turning spaces have been taken into account. At some point, steps and thresholds become difficult to manage.

Let’s all hope to stay healthy well into old age... but just in case that's not so, I expanded the shower to 150cm x 150cm (59 inches x 59 inches)... and added the window in the guest bathroom.


Try to find a place to shower that has such a large shower. We have one that is 1m x 1.40m (39 inches x 55 inches) – which I think is just about right. Any larger, and I would feel cold while showering.

Possibly, a boxed-in (drywall) vent pipe of about 10-20cm (4-8 inches), running upwards through the roof for drainage venting, will be added for the downward drain – then nothing fits in this size with a fixed shower base (such as enamel). Of course, tiling around the corner is also an option.

True. I think it will just be tiled and a curtain will be installed instead of a door. That also adds some flexibility. I also considered routing the supply and exhaust air of the mechanical ventilation system through the corner of the wall.

I would prefer to place the staircase on the right side of the hallway rather than the left, so that the living room offers a bit more privacy.

Best regards,
Sabine

Unfortunately, that doesn't work with the guest bathroom, and the front door would be right next to the garage. I also wouldn't want to move the garage further back.
