Hello dear house-building forum!
I have already done a lot of reading but still haven't found a suitable solution or optimization for our single-family home. Maybe you can help me further?!
First, some details about our single-family home:
Development plan/restrictions
Plot size – 890 sqm (9579 sq ft)
Slope – no
Site coverage ratio – ?
Floor area ratio – 0.4
Building envelope, building line, and boundary – building line is 6 m (20 ft)
Edge development?
Number of parking spaces – garage for 1 car
Number of floors – 1
Roof type – any
Architectural style – bungalow area, old house still standing, will be completely demolished
Orientation – ?
Maximum heights/limits:
- Ridge height max. 9 m (29.5 ft) measured from the top of the foundation
- Eaves height of the single-story main structures must not exceed 2.75–3.00 m (9.0–9.8 ft) (measured from top of foundation to bottom edge of gutter)
- Roof extensions allowed up to max. 2/5 of the eaves length
Other requirements – originally a designated bungalow area
Client requirements
Style, roof shape, building type – single-family home modern, pitched roof, solid construction
Basement, floors – no basement, ground floor, first floor, finished attic
Number of people, ages – 3–4 / 30, 31, 1 year
Space needed on ground and upper floors – 80–90 sqm (860–970 sq ft)
Office: family use or home office? No office but a guest room with a desk
Number of overnight guests per year – 20–30
Open or closed layout? ?
Conservative or modern construction? Rather modern
Open kitchen, kitchen island? Both
Number of dining seats – 6–8
Fireplace – yes
Music/stereo wall – yes, in a small version
Balcony, roof terrace – no
Garage, carport – garage with sauna and small lounge area, space for DIY/workshop
Utility garden, greenhouse – no
Other wishes/special features/daily routine, including reasons why this or that should or should not be included: Utility room is intentionally on the east side because daylight in the guest room and guest bathroom was more important to us. The sauna is intentionally located in the 2.20 m (7.2 ft) high garage because we want direct access to the garden.
House design
Who planned it: self-drawn, architect digitized. BUT: so far only the dimensions are set, interior walls, windows, and furniture are partially not yet in the correct positions!
-Planner from a construction company: no
-Architect: yes
-Do-it-yourself: all
What do you particularly like? Why? We think we have a coherent flow for everyday living but are still open to improvements and tips for saving space
What don’t you like? Why? Solution in the garage with sauna, first floor: master bedroom with dressing room, which should be able to fit at least 2 wardrobes of 3 m (10 ft) each
Price estimate according to architect/planner: 320,000
Personal price limit for the house, including equipment: 300,000
Preferred heating technology: heat pump with photovoltaics
If you had to give up something, which details/extensions
-Can you live without: we are open to suggestions
-Can’t live without: guest room, sauna, size of utility room
Why is the design the way it is now? E.g.
Standard design from the planner? Inspired by Viebrockhaus Maxime 800
Which wishes have been implemented by the architect? So far everything exactly as we drew it...
A mix of many examples from various magazines... no
What makes it in your view particularly good or bad? Good everyday workflow, short distances, all the rooms we want are accommodated
What is the most important/fundamental question about the floor plan summarized in 130 characters?
Can the rooms in the house still be optimized, e.g. on the first floor?
How can I fit a sauna with a small lounge area in the garage without feeling cramped?

You have about 20m² (215 sq ft) less than we do – and the garage is roughly the same size.
20m² (215 sq ft) x 3m (10 ft) = 60m³ (2,119 cu ft)
We have 1,250m³ (44,132 cu ft) – so you have about 1,150m³ (40,628 cu ft) * 350 = 400,000€
No idea where your 300,000€ come from.
Regards According to our architect’s calculation, we have 797m³ (28,140 cu ft).
House size = 172m² (1,851 sq ft)

So the sauna is only accessible from the garden or the garage, or is that the tiny workshop? The sauna is on the left, only accessible from the garden. The tiny workshop is on the right, serving as a passageway.
A small selection on the topic of budget:

Regarding the floor plan:
Draw in all the furniture at the correct scale according to what you want or already have.
Keep walking paths in mind.
Do you really want to squeeze a sauna into the narrow storage room next to your bicycle, lawn mower, and similar items? That feels more like a storage unit than a wellness area.
A bathroom used as a passageway doesn’t work. That would mean Uncle Franz is sitting on the toilet while the kids walk through.
Overall, I would start the floor plan from scratch after you have planned your budget.
Demolition: Ask several demolition companies. And if it’s not urgent, don’t set a strict deadline. We looked for over a year for a company that could gut and demolish the building. Quotes ranged from 45,000 to over 100,000 including disposal fees (this was more than what you have and disposal costs are quite high in Bavaria).
Have the basement carefully filled and compacted. Be sure to request a compaction certificate with load plate tests if you plan to build on top.

Double staircase: space-saving stairs leading to the attic. The staircase is not properly installed yet; as mentioned in the introduction thread, many elements are still not in their final positions. Here, we are looking at drafts where interior walls, furniture, doors, and windows are not optimally placed.
Backpack in the bathroom: I don’t think the bathtub is placed correctly. Originally, it was meant to be installed in the bay window area (which is why there is a wall above the staircase). However, it doesn’t fit there, so it is planned to be centered in the bathroom under the sloped ceiling with a skylight. The bay window will have two large windows, and the stairs will then be open; I don’t think we have what is called an open stairwell…
