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?

I also see a necessary reduction here. Too much enclosed space for the budget. No guest toilet, two small rooms as offices.

Hello,

I’ve finally found a spot for the guest bathroom. WiCi Concept offers very space-saving solutions where the sink is placed on top of the cupboard. I also rearranged the kitchen. I think everything is starting to look quite well thought out.

Over a year ago, I already designed a plan (without a plot) without considering the site restrictions. Back then, there was a nice double garage and a house that was rather wide than deep. But the reality is that an affordable building plot in a good location is extremely rare, and you can be very grateful if you manage to get one at all, as we did. Therefore, I’m focusing my planning strictly on what the building regulations allow.

All the comments about the budget are probably well-intentioned, but this is really only about the floor plan, and I am happy to receive feedback on that.

Best regards
Johannes

Hmm, according to a VDI guideline (I would have to look up the exact number), a toilet cubicle must be at least 90 cm (35 inches) wide. From what I see, yours is only 65 cm (26 inches)?
I think I would definitely get stuck in there...
And of course, costs are also a factor – here, some people (not everyone who chimes in, I am less so) have solid experience with how much a house actually costs. They can roughly estimate prices just from the floor plan. If they say, "the price won’t work unless the fittings are significantly reduced," that’s at least a useful indication...

Good night.

A guest toilet measuring 0.65 x 1.10 m (2.1 x 3.6 ft)? - now it’s getting a bit ridiculous for me...

I also think you can do without a guest bathroom.

Regarding the kitchen… it’s better to have the main cooking area on the left side of the plan, a peninsula at the top of the plan, and tall cabinets at the bottom of the kitchen. This also allows access to the garden without always having to walk around the peninsula from the living area and inevitably past the dining table, for example, when bringing in groceries.

What’s the point of planning everything carefully now, only to realize in a few weeks that the finances don’t add up? Are you one of those who can almost endlessly increase the budget? Or are you more likely to end up cutting costs on fixtures and, eventually, on the size of the house?
I’m really curious why you seem so calm about potential budget constraints.
