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

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

Hello,
Just one example: If your gross floor area (GFA) is fully utilized at 137m² (1472 ft²) for the house, then you may only build a total of 68m² (732 ft²) more with garage, parking space, terrace, driveway, and garden shed. With your triple garage, it should be clear to you that this alone, including the forecourt, will already exceed those 68m².
PS: Your floor plan is missing a staircase and many rooms do not have doors.
Maartina schrieb:So why are you planning "2 stories + expandable attic"? What does the building permit / planning permission (BPL) indicate now, in Roman numerals inside a circle? Is it a "1" or a "2" (full stories)?
A 1.5-story building is required, which is why we are having difficulties achieving a reasonably sufficient living space upstairs, let alone nice room sizes.
Maartina schrieb:If even the professional couldn’t do better, there might be a discrepancy between your conflicting requirements (room program) and the facts (gross floor area, budget). I think this is quite likely. No one can create a miracle solution here.
We have already had architects plan everything, but each time had to accept huge compromises...

So... on the upper floor (the level without garages), the toilet and shower do not work with just a knee wall and sloping roof. Dormers or not.
The beds can only be accessed from one side, and the open-plan room is also interesting.
It’s all somehow not right.
But that doesn’t matter, because that’s what architects are for.

We have also had everything planned by architects, but every time had to accept significant compromises. Since you are now looking for a general contractor, it would be great if you could share the design that you are planning to go with.

What kind of compromises?
Please show the architects’ designs and a site plan.
There’s no point in discussing self-made designs. Unfortunately, they have to be discarded.
Hello,
sorry, but this is only slightly better than the rough sketch you made yourself.
In the granny flat, there is a kitchen that is huge compared to the living room, a dark and uninviting entrance with the staircase, an impractical bedroom on the upper floor, bathrooms with space for a corner bathtub in the smaller bathroom but only a 750 x 900 mm (30 x 35 inches) shower, .........
I’ll stop the list here and suggest starting over.
