Hello everyone,

this is my third post in this forum. First of all, thank you for the valuable tips I have already received. I think I have learned a lot so far.

I have linked the previous posts below. To avoid any misunderstandings, I will list all the necessary information again. Therefore, reading the old posts only makes limited sense. For completeness, I have included them here.

For the initial selection, there were three rough floor plan drafts. One was from Yvonne, the second from kbt09, and the third from the planner/ourselves. Many thanks to both of you for the good ideas! After some time for consideration and consultation with the developer, we decided to pursue the third floor plan.

If I say that the plot is not easy, I am understated.
Maybe this is an approach?

I continued with the approach from the floor plan adjustments.

Architect’s floor plan of a single-family house with living room, kitchen, bedroom, and bathroom.




Floor plan of a building on a plot as architectural drawing

Now to the main topic.

At the end of April 2019, we reserved a plot (plot no. 10) and started working on the floor plan. The plot is tied to the developer, and unfortunately, the planner has not turned out to be very creative (myself included). Two weeks ago, we had another meeting with the developer and talked about the three options mentioned above. We then chose one variant and want to proceed with it. We have now received a draft, which certainly still needs improvement.

For this reason, I would like to present the floor plan here again for discussion and hope for feedback, ideas, suggestions, and tips. Maybe you will immediately see things that “just don’t work” or are not practical for everyday life. I have also already noticed a few things that I would change, but since we will probably make quite a few modifications anyway, I have not yet suggested my own improvements in the floor plan. Also, the planner and I have not yet discussed doors and windows.

Attached again is the completed questionnaire.

Development plan/restrictions
Plot size: 819m² (8809 sq ft)
Slope: NO
Floor area ratio (FAR): 0.4 (allowable exceedance 25 per 100)
Gross floor area ratio (GFAR): 0.6
Building envelope, building line and boundary: On the northeast side approximately 31m (102 ft) deep, west side approximately 35m (115 ft) deep, plot frontage on the street 18.7m (61 ft) and rear boundary (development limit) approximately 27m (89 ft). The major challenge with the plot is the narrow width at the front. Depending on house orientation, after the 3m (10 ft) building setback on the street side, we have about 19.5m (64 ft) to 20.4m (67 ft) available. This means that if the house is parallel to the street, it is 19.5m (64 ft), and parallel to the neighbor in the northeast direction about 20.1m (66 ft).

Side building setback: 3m (10 ft)
Number of parking spaces required: no specification
Number of floors: maximum 2 full floors
Roof type: gable roof, hip roof
Other requirements: Garage must be at least 5m (16 ft) from the property boundary.

Client requirements
Style, roof shape, building type: bungalow with hip roof
Basement, floors: no basement due to high groundwater level
Number of people, age: 4 people aged 36 years (female), 37 years (male), 2 years (child), 7 months (child)
Room requirements on ground floor and upper floor:
Ground floor: living/dining/kitchen, utility room, guest toilet with shower, hallway with coat area and stairs to the upper floor, children’s rooms, master bedroom, bathroom, and storage room.
Upper floor: office, children’s playroom and additional storage space.

Office: family use or home office? home office
Overnight guests per year: 1–2 times
Open or closed floor plan: a mix of both
Conservative or modern design: a mix of both
Open kitchen, kitchen island: open kitchen with island would be nice but not a must, closed kitchen also has advantages
Number of dining seats: 4, with the option for 6–8 would be nice but not essential
Fireplace: no
Music/sound wall: sound system in the living room
Balcony, roof terrace: no
Garage, carport: Space for 2 cars is required. Currently, I am considering a garage (3x6m / 10x20 ft) and carport (3.6m / 12 ft).
Kitchen garden, greenhouse: no
Other wishes/special requirements/daily routine, including reasons for preferences or restrictions

House design
Who designed the plan:
-Developer’s planner / do-it-yourself
What do you particularly like? Why?
-There should be enough space in the coat area and behind the stairs to store jackets, shoes, etc.
-The children’s rooms have a comfortable size and are practically equal in size.
-Living room/kitchen are close to entrance and garage.
-The storage room has a good (central) location.
-


What do you not like? Why?
-Garage/carport is very far to the back (but I can probably live with this)
-The utility room is comparatively large and long
-The kitchen in my opinion is somewhat too large
-The living room is only the desired minimum size and could use 5m² (54 sq ft) more
-The main bathroom is located between both children’s rooms and the noise from showering and toilet use is likely to be a major issue
-The main bathroom could be slightly larger
-Between the garage and the property boundary there will be a dead space where weeds will probably grow later. Does anyone have ideas on how to prevent this?
-The garage is currently planned with a length of 9m (30 ft), of which 6m (20 ft) is for the garage and 3m (10 ft) for a storage room. The current position directly behind the garage is not optimal in my view


Price estimate according to architect/planner: no new price estimate received yet
Personal price limit for the house including equipment: 400,000
Preferred heating technology: heat pump

Why is the design the way it is now? e.g.
ideas from planner and do-it-yourself ideas from me

What is the most important/basic question about the floor plan summarized in 130 characters?
The main bathroom is located between the children’s rooms. How can we reduce noise disturbance to a minimum?
Imagine I drive a Skoda Superb into the garage. Since the garage is on the property boundary and the driveway narrows between the house and property line, I have to enter at a slight angle. Does this cause problems in everyday life? See pictures.
Assuming we build a double garage directly attached to the bungalow instead of a garage and carport, is there anything special to consider during construction?

I experimented again with an L-shaped bungalow ops:

The idea was to create a proper summer evening barbecue terrace.

On the north side, a garage (which means the window in the utility room has to be removed) with an additional storage extension, alternatively a carport with storage extension here as well.
In the southwest, another carport with a nice partition wall.
If the house is placed at the 5m (16 feet) corner just like the northern garage, in my opinion it is far enough away from the street to create a comfortable spot in the corner of the bungalow for summer evenings. Also undisturbed by neighbors, so you can enjoy the evening sun.

You can still have a terrace in the southeast, and might consider adding an exit from the children’s rooms, etc.

Just meant as inspiration for now.

The staircase is primarily determined by the floor-to-floor height. I usually calculate it using the website (-> Google) "Treppe 1x1". It’s good to keep a few basics in mind. For example, I wouldn’t go below 1m (3.3 ft) in width in my house—stringers and railings make it narrower in the end. Also, I always try to keep the riser height around 18 to 18.6cm (7.1 to 7.3 inches) and the tread depth between 26 and 27cm (10.2 to 10.6 inches). Headroom should not be less than 2.10m (6 ft 11 in).

I experimented a bit more with the floor plan. This is how I would do it now, although the stair is normally a quarter-turn without a landing (software error).

I only see a gable roof in the attic—without a knee wall, a hip roof doesn’t make sense in this case and, in my opinion, looks terrible. Maybe you could open the ceiling at the entrance all the way up to the roof for a small gallery. Add some nice large windows there—it would look something like this:

Okay, just playing around.

Did I miss a reply, or is my question about whether an offset mono-pitched roof is also permitted still unanswered?

Are you still expecting answers from the original poster? Well, at least their behavior matches the local development plan, which raises more questions than it answers. The usage template actually specifies gable and hip roofs. The legend confirms this. However, there is no reference to the legal basis here. According to the Building Code, roof shape and pitch cannot be defined. This must be regulated in a state-level design ordinance, which can be integrated into the development plan but must then be clearly indicated—something that is not the case here. The justification for the development plan does not clarify this either; on the contrary, it even mentions “simultaneous specification of roof shape and pitch.” Yet, in the plan documents, I find no indication of roof pitch. In my humble opinion, the specification of the roof shape is invalid.

That’s beyond the builder’s capabilities.

I don’t think the staircase width is important here; it could also be 90cm (35 inches). After all, it’s not a main staircase.

The construction supervisor can’t do that.
So, what now? A staircase? Or the gallery? ops:

I would like to design the living areas more in this direction:


Floor plan of an apartment with living room, dining room, kitchen, bathroom, shower, hallway, and storage room.


But then I can’t fit a staircase anymore, and the rooms end up adjacent to the "noisy" areas again. What do you think?
