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?

Lower Saxony offers affordable building plots:

180 sqm (1,940 sq ft) x 1,900 = 342,000 Energy Saving Ordinance 2016 (Viebrockhaus itself is more expensive, but I’m not entirely sure... it’s easy to be mistaken here)
Outbuildings 25,000 +
Sauna 5,000
Fireplace 8,000–10,000 AI
Flooring/painting in EL 20,000

= approx. 400,000€

Plus exterior landscaping around 20,000
Plus additional construction costs of 25,000 (flat land with good soil)

I think the walk-in closet is poorly designed. How wide is the room? 2.24 meters (7 feet 4 inches)? That would leave only about 1 meter (3 feet 3 inches) for the walkway, since you need at least 2 times 60 cm (2 times 2 feet) for the wardrobes. This means you’ll end up walking back and forth between the bedroom and the closet several times just to pick out and try on clothes... There’s a better way to do this.

The budget won’t be sufficient, but this was already mentioned. Is that actually your budget just for the house, and are you calculating additional construction-related costs separately, or are those already included?

No, you’re interpreting that exactly right!

Explain to us: what is the key advantage of a transit guest toilet?

I recommend moving away from simply copying a template. As you can see, it doesn’t work.

More likely the stamp approval of a general contractor. Any independent architect would act in an advisory capacity (meaning also discouraging) if the client planned something impractical, instead of just redrawing it exactly as it was. At least in the knee wall area behind the bedroom, this should be obvious even to non-experts, unless spatial imagination is severely lacking.

Where do the measurements even come from if furniture hasn’t yet helped verify the dimensions?

Does the bungalow have a basement? - I would reconsider a full demolition carefully. With such a low eaves height, it will be tight for the garage, which is just one step lower, to fit smoothly under the roof overhang. From the demolition, I infer that this is not about filling building gaps but preserving the character of the area, so chances of exemptions that would allow otherwise seem slim.

That should actually be our budget for the house itself, and we would add the additional construction-related costs on top of that, so we plan for them separately.
