Hello, we are planning our house, which we want to share with my mother (separate apartment approximately 70 sqm (750 sq ft)). We want to maximize the floor area with 137 sqm (1,475 sq ft). Maybe someone has ideas, suggestions, or improvements. We are grateful for any input.
Development Plan / Restrictions
Plot size 459 sqm (4,940 sq ft), 21.5 * 21.4 meters (71 * 70 ft)
Site coverage ratio 0.3
Building area 15.4 * 13.4 meters (50 * 44 ft)
Building line 3 meters (10 ft) and boundary line 5 meters (16 ft)
1.5 storeys
Roof type: steep roof, minimum 35 degrees
Street-facing gable
Maximum heights / limits 9 meters (30 ft)
Other requirements: max 1.15 meter (3.8 ft) knee wall
Owners’ Requirements
2 storeys + expandable attic
Upstairs: 5 people, including three small children. Ground floor: 1 person, mother
Space requirements ground floor
Mother’s apartment: 2 rooms + living room + open kitchen,
separate office with WC.
Space requirements upstairs: 3 children’s rooms, master bedroom, open living and kitchen area, two bathrooms
Office: home office, possibly for visitors
Conservative construction
36 cm (14 inch) masonry
Open kitchen, kitchen island upstairs
Number of dining seats upstairs 6-8
Possibly a balcony
Garage added later
Staircase to attic with roof window accessible from both households
House Design
Designed by:
- Do-it-yourself
What do you dislike? Why? Dark corridor
Personal budget for house including fittings: 400,000
Preferred heating system: heat pump
Why is the design like it is now?
What do you think is particularly good or bad about it? Maximum size utilized, difficult implementation due to sloping roofs
Thank you, maartina

Thank you. But there is still room for improvement, right? (Apart from the missing children's room doors)
I'm surprised that an architect would forget doors and just hammer some blocks into the walls.
I find the layout on the ground floor with the utility room/work area/granny flat acceptable.
However, in almost every room, including the upper floor, you could adjust the walls to make the space more functional.

sorry but this is only marginally better than the sketch you made yourself. This time I wanted to approach the discussion a bit more diplomatically and kindly, not so bluntly honest, and then you beat me to it.

Here are the current floor plans Oh dear, ouch.

[...] I'll stop the list here and suggest starting over. I can only agree with that advice, but I will still try to point out some additional issues, since the original poster apparently finds it difficult to see the flaws themselves (after all, no one wants to build something that’s just torture). But seriously, someone really managed to make nonsense even crazier:
Living room for the granny flat is a trapped space # room sizes kitchen – living room – and especially storage room are completely out of proportion # the single bedroom of the granny flat by itself is okay, but the master bedroom is more like a walk-in alcove # the upper floor just doesn’t work at all, especially the balcony with a knee wall height of 115cm (45 inches) is a joke, overall, the designer clearly lacks any spatial imagination # the wall layouts on the upper floor are a nightmare, both for masonry and tiling, and as my predecessor already mentioned, this is far from the end of the story. Not just to complain, I admit that I used to plan similar rubbish myself in the past – though back then I was only twelve, so looking at it now almost brings back old memories.
I too would bet my crystal ball that the root of the problem lies in roughly a gazillion more wishes than the building volume can accommodate.

Besides the issues already mentioned, you might want to reconsider the overall concept.
Due to the sloped ceilings, at the moment five people have almost the same amount of space upstairs as one person has downstairs. That seems disproportionate to me.
The office is quite large – how much space is really necessary there? Could visitors be expected to use stairs, or do they have any mobility limitations?
Are there regulations regarding dormer size?
