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?

I really like it when someone designs a house based on their own living preferences rather than following common trends.

I have indeed encountered a walk-through toilet in two houses. Of course, we always had a good laugh about it, but the respective families lived quite well with it. You simply close two doors, and that’s it.

A sauna in the garden area is a great feature. Instead of placing it (expensively) in the garage, I would plan and apply for a separate sauna building.

Regarding the budget, I am also very skeptical that you will be able to stay within it. Architects tend to be optimistic with their estimates, and when the details are discussed, the limits are often exceeded.

Are you sure your interpretation is correct? Based on that, you could build anything, right?

I am certain this is not just an interpretation, as my quote comes directly from our current valid development plan.
Of course, I don’t know whether the local municipality today might see it the same way you do...

For the eaves height, the measurement starts from the ground/soil level and goes up to the point where the roof meets the exterior wall.
With a room height of 2.75 meters (9 feet) and a ceiling thickness of 25–30 cm (10–12 inches) measured from the upper edge of the load-bearing floor (OKBP), you already reach the maximum 3.00 meters (10 feet).

Maybe the architect should handle everything and be involved from the very beginning, ideally already during the preparation of the development plan / zoning plan?!


The architect has been involved from the very start; without them, we wouldn’t have been able to calculate this house. It all depends on the number of stories, and as mentioned, the eaves point is referenced and defined exactly as shown in our development plan / zoning plan and illustrated in our cross-section. If anyone complains, I just need to refer to the development plan.

I’ll believe it when I see your building permit / planning permission.
The planned house doesn’t resemble a bungalow at all.
Not that I wouldn’t wish that for you, but before you invest too much effort in planning, you should definitely show it to the building authority.

A simpler explanation for the eave height of a house is as follows: The drip edge of the house can be referred to as the height of the eave. This means the roof eave itself. Usually, the rain gutter is installed at this eave because all the water accumulated on the roof drains off at this point. However, it is important not to generalize and equate the height of the gutter with the eave height.
