Hello everyone!

Although we are from Austria and building here, we have been following various posts in this forum for some time. There are many creative minds here, and I really appreciate your advice in the other discussions.

We ourselves have been in the house planning phase for quite a while. We recently purchased a plot of land south of Vienna and plan to start construction in 2020. We want to build with solid construction methods, but we are still deciding between brick (which is very common here) and aerated concrete blocks (we really like the kit house concept from Ytong based on what we’ve heard so far, although it is quite rare in our area).

Efficiency in the use of living space is very important to us (no unnecessary features, no long hallways, no balconies or bay windows), as well as in the building services (heat pump, controlled mechanical ventilation system, etc.).

I assume there isn’t much experience here with Austrian building regulations, so I will try to answer any questions that come up as quickly and competently as possible.

Here is the completed questionnaire:

Zoning Plan / Restrictions
Plot size: 604 m² (6500 ft² approx.)
Slope: No, completely flat
Site coverage ratio: (not applicable here) - 32% buildable area
Floor area ratio: (not applicable here)
Building setback lines and boundaries: front setback 3 m (10 ft), side setback 3 m (10 ft) or half the eave height of the adjoining façade – whichever is greater, rear setback 3 m (10 ft)
Edge building restrictions: within the setback zone up to a maximum height of 3 m (10 ft)
Number of parking spaces: 2
Number of floors: not specified in the zoning plan
Roof shape: no restriction according to zoning plan
Architectural style: no restriction
Orientation: no restriction
Maximum height/limits: max. building height 6.8 m (22 ft) (eave height)
Other requirements: none

Client Requirements
Style, roof shape, building type: classic rectangular shape, gable roof or staggered shed roof, simple building form without bay windows or dormers, no balconies!
Basement, floors: basement (gym, workshop, laundry, mainly storage), ground floor (living areas + guest room), upper floor (bedrooms)
Number of occupants, ages: male 28, female 34, child 0.5 years, child 11 years (every second weekend + school holidays)
Space requirements ground floor, upper floor: ground floor (shower bathroom, guest room/home office/play/multi-purpose room, living room, kitchen, pantry), upper floor (bedroom including walk-in closet, 2 children’s rooms, bathroom), basement (gym, laundry, storage, workshop)
Office: family use or home office?: 80% family use as playroom, 10% home office, 10% guest room
Overnight guests per year: approximately 5, mainly relatives visiting for various celebrations from afar
Open or closed layout: open plan
Conservative or modern construction: rather conservative but open to “unconventional ideas”
Open kitchen, kitchen island: open kitchen with breakfast bar
Number of dining seats: permanently 6, at family celebrations minimum 12 temporarily, >16 long term
Fireplace: no
Music/speaker wall: no – but large TV frequently used
Balcony, roof terrace: definitely no!
Garage, carport: carport within the setback zone (on the north side?)
Vegetable garden, greenhouse: definitely yes! Gardening is a big wish and the main reason for the whole project
Other wishes/special features/daily routines, explanations if desired: The house should be as efficient as possible (during construction and especially in operation), therefore no awkward bay windows etc. (ratio of surface to volume)
Additional requests: controlled mechanical ventilation system, laundry chute, non-load-bearing partition wall between the children’s rooms so it can be removed in a few years if the older child no longer lives at home. The most important thing is a large garden, so that’s why the basement is desired to minimize the building footprint. The kitchen must be large enough for at least two people to cook at the same time – this is currently a problem in our apartment.

House Design
Designed by: DIY with a lot of input from planners
What do you like? Why?: almost all wishes implemented
What do you dislike? Why?: pantry is quite small, upper floor still not quite perfect, niche in the corridor as storage replacement for vacuum cleaner etc.
Price estimate according to architect/planner: €430,000 turnkey, €350,000 “turnkey with owner involvement”
Personal price limit for house, including fixtures and fittings: €350,000 in shell and core condition is the goal, with a comfortable buffer, but that would be our ideal
Preferred heating technology: heat pump with ground source collector (trench collector)
Note: We are not under time pressure for planning or construction. We are very willing and able to do much of the work on the house ourselves. Providing appropriate “self-performance proof” for the bank is not a problem either. This helps keep construction costs low.

If you have to give up something, which details/finishes
- could you give up: almost everything except the pantry and open kitchen
- could you not give up: pantry, open kitchen, and preferably not the controlled ventilation

Why is the design the way it is now?
A mix of many examples from model home parks, magazines, and many discussions with planners/architects etc.

What do you think makes it particularly good or bad?
All the rooms we imagined are present, relatively short circulation routes, hardly any wasted space

What is the most important/basic question about the floor plan in 130 characters?
What do you think of the design? Where do you see potential for improvement? Placement of laundry chute?

I look forward to your opinions and comments!

Best regards,
your Gugelhupf

The carport also fits on the north side, then the house shifts 2 meters (6.6 feet) to the south

The original poster probably assumes that the sun does not move those 2 meters (6.6 feet) with the house and that it suddenly stops shining at the garden fence.

I would leave it as is. The carport clearly marks the boundary to the playground. The terrace is just around the corner behind the house. A small Biohort shed and a fence complete the setup. This will not make the house any darker, and the shade on the south side provides welcome heat protection. In Vienna, summers are no longer very different from those in Italy—at least according to our son, who has been living there for some time now, after previously living in Rome. There, you don’t want sun, but shade. Apartments in the city, especially the newer ones, all have air conditioning. Karsten

What is this sentence trying to say? That the car next to the playground serves as a boundary? Up to here and no further, because the car is standing there?
In my opinion, a hedge or a fence still works best as a boundary.

Yes, it will. A large roof over the southwest windows blocks the sun, which poses a risk of seasonal depression from September to April.

Whether to install shading in the summer is a different question, of course. I would rather use louvers or blinds for that.

In short, we disagree on this.

I can’t share the enthusiasm for the mania of bringing large amounts of direct sunlight into the house. It causes glare, provides good heat in winter, but in summer you definitely don’t want it inside. Large windows that provide plenty of indirect daylight are the preferred solution.

By the way, it would be ideal to have windows extend from ceiling to ceiling rather than floor to ceiling. Since most ceilings, unlike most floors, are light-colored or white, they reflect much more indirect, diffuse daylight into the room.

Logically, shading systems should operate from bottom to top rather than the other way around. Do such systems even exist?

Simple ideas are known to be the best...

I don’t quite understand that. How can windows provide indirect light?
