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.

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 also like the living areas (dining / living) best as they are.

Relocating the washing machine is an option. I would rather invest in very quiet appliances. I did the same with my refrigerator.

In the bathroom next to the bedroom, I already moved the noisiest pipes (toilet, shower) to the opposite wall. I would probably also make the wall towards the bedroom a bit thicker. The question is how the bathroom usage is distributed with children. Presumably, you are the last ones using the bathroom?

The hallway is too narrow – the house needs to be longer here (which soon becomes a bit excessive).

Lighting is not an issue – you can place a glass panel next to the door. It could be positioned in front of the stairway. The door itself could have a large glass section.

Remove the wall between the living room and dining area. Is it large enough?

But maybe start again from scratch. I have another idea...

Our refrigerator is only 5 months old since we just moved and sold our old kitchen. It doesn’t cause any disturbance, same with the dishwasher. In our rental apartment, the kitchen is directly connected to the living room, but the dishwasher is so quiet that it’s not a problem. The washing machine and dryer are very loud. Something can probably be done about the dryer, but the washing machine is a Siemens IQ800.

In the evenings, my wife and I are the last ones in the bathroom. In the mornings, we go in together with the children since they are still small.

You’re right about the lighting. You can place a glass panel next to the door.

If I imagine removing the wall, the space is large enough. But I keep it in for odor control and separation.

Here is a version measuring 17m x 10.5m (56ft x 34ft) plus a front porch. I don’t think it’s bad at all, especially since the family would have plenty of space in the living area. Also, you won’t risk being run over by the car. The laundry room could be small if the technical equipment is relocated upstairs. However, there is one problem: no light in the hallway. You might need to use skylight spots, or even better, open up the ceiling in the hallway as I mentioned earlier and then install double casement windows. That would be pretty cool.

How wide is the extension? I ask because the garage is set too far forward (towards the street, I mean). It can be no more than 5m (16ft) wide up front if the house is 11.5m or 12m (38ft or 39ft) wide.

2.25m (7.4 feet).
The plot gets wider toward the back in a trapezoidal shape, right? Unfortunately, I don’t have the exact angles. But based on the boundary lengths, I made a sketch. The house fits easily within the 3m (10 feet) setback from the street. Of course, it’s a rough estimate. If you have your survey documents, you could measure the angles…

Hmm, is the washing machine really such a problem? You don’t usually run it at night anyway, right?

That’s correct, the plot does widen towards the back. But even with a width of 6m (20 feet) for the garage + 10.5m (34 feet) for the house + 2.25m (7.4 feet) for the extension + 3m (10 feet) for the setback from the boundary, it still isn’t enough. Yes, you don’t have the exact angles and unfortunately, I don’t either. I’ll call the structural engineer tomorrow. Maybe he can send me something.

Thank you very much!!!

Katja, with your bungalow, you are entering the 3m (10 feet) setback area on the right side.

I’m questioning the development of the attic once again... and if it’s going to be a hip roof, here is my version 1 again, now with a 22° hip roof and an extended carport/storage area.

This is a good floor plan.

Advantages:
- For me, the terrace location is very good
- Living, dining, and kitchen areas feel very spacious
- Bedroom with walk-in closet is nicely large

Disadvantages:
- Main bathroom and kids’ bathroom are relatively small with limited storage space
- Since my wife and I share the office, it feels a bit small
- Fairly long layout, but the carport/storage area makes it look good overall

My wife would prefer to have a main bathroom shared by both children and parents. I don’t mind either way and don’t see it as a disadvantage. It’s a matter of personal preference...

I know the question about the roof shape came up today.

Since the question about a gable roof has been asked frequently, I did some research. Here is an example of a shallow gable roof with an elevated knee wall. The question is how this affects costs compared to a hip roof. The house you see here measures only 13x12m (42.7x39.4 ft). I find it visually appealing, but I wonder how it would look if the house were, for example, 11.5x16m (37.7x52.5 ft). I also wonder how it would appear if a covered terrace were added later.






Roof pitch / knee wall height: 25° / 55cm (22 inches)

Attic floor plan: office, work area, storage, shower/bathroom, stairs, storage 2, carport.


The living space under the roof here would be 56.20m² (605 ft²), which is very good...
