ᐅ Floor Plan Design for a 100 m² Bungalow with Potential for Expansion

Hello everyone,

I’m planning to build a new house on a plot of land. The plan is for a bungalow with approximately 100 m2 (1,076 sq ft) of living space. The attic will not be finished initially but kept as a reserve. However, I would like to include the attic layout in the planning now.

The goal is to have two roughly equal-sized rooms in the attic for guests or potentially as children’s bedrooms. Additionally, having a bathroom (WC) in the attic would probably be useful.

I’m satisfied with the ground floor, but I am not yet happy with the attic. I would like to make the hallway in the attic smaller. Maybe it would be possible to combine Guest Room 1 and Guest Room 2 into one and turn the attic space into a second room. Perhaps the attic bathroom could be moved closer to the top of the stairs, and the wall between Guest Rooms 1 and 2 could be shifted closer to the staircase.

However, I can’t think of a good solution. Do you have any ideas?

To summarize my questions:
- Is the ground floor okay as it is?
- Any ideas for the attic? Or is it maybe already optimal?

Thank you.

House Design
Who designed it: architect
What do you particularly like? The room layout and arrangement on the ground floor
What do you not like? The attic. The hall upstairs seems to take up too much space in my opinion.
Cost estimate from architect/planner: not received yet
Personal price limit for the house including equipment: 360k
Preferred heating system: heat pump

Why was the design created as it is now? As mentioned, there are two garden beds on the left side at the front, so the driveway to the carport is on the right side. The utility room serves as an entrance area and storage for groceries. The kitchen and living room should face the garden; also, the kitchen should be right next to the utility room for pantry storage. The bedroom should have no window facing the street. The other rooms on the ground floor are then arranged accordingly.
The attic is a standard design from the architect, with which I am not very satisfied. The attic will probably not be finished, but I would like to have the plan finalized now and run any necessary wiring during the new build.
Which wishes were implemented by the architect: the ground floor matches my preferences
What makes it especially good or bad in your opinion: I like the room layout, and the room sizes could maybe be adjusted a bit. The bathroom and WC can probably stay as they are. The bedroom and living room height should not be reduced to avoid cramping. For the size of the kitchen, office, and utility room, maybe some adjustments are possible by moving walls.
The utility room should house the heating system, washing machine, dryer, and storage space for supplies. This room might be made smaller.
Regarding the attic, the current roof pitch appears to be planned at 45 degrees (24°). This might look quite bulky in relation to the ground floor. I would suggest considering laying a screed floor, raising the knee wall (dormer wall), and reducing the roof pitch.

The question is... are there already two cars? Why such a wide driveway?

You might also consider insulating the sofa/TV area and combining the kitchen and dining spaces, so you wouldn’t need two tables, especially since one would likely remain unused.

Regarding the bathroom and guest toilet, it might be possible to design the layout so that the toilet is accessible both from the hallway as a guest restroom and from the bathroom area as the main toilet, separated by a sliding door towards the bathroom. This way, you save space by having only one toilet.

Are there any regulations about building lines, roof ridge orientations, eave heights, or similar?

Kerstin, I can't imagine there are any relevant requirements. Building lines are very rare nowadays—just take a look at the neighboring properties, where pretty much anything is allowed. Building boundaries usually only exist as a 3-meter (10 feet) perimeter around a lot.

Bathroom and guest toilet… one could possibly design it so that the bathroom toilet is positioned in a way that it can be accessed both from the hallway as a guest toilet and from the bathroom as a bathroom toilet, separated from the bathroom side by a sliding door. That way, you save one toilet.

But then you might as well skip this room altogether. The purpose of a second toilet is precisely to have a guest toilet.

The purpose of this solution is that guests only need to enter the toilet area. At the moment, I can’t immediately think of a design solution for this in the current layout.

However, due to other concerns, such as the sun’s path and its impact on the rooms, I’m not entirely convinced by the current layout. The arrangement and planning of the rooms are acceptable, but considering the sun’s position and related factors, I don’t find the solution suitable yet.

I haven’t read everything, but just two thoughts:
1. When you build, forget about the flower beds. They will be gone anyway. If you want to save anything, it’s better to dig it up and move it to a safe place.
2. If the attic conversion is optional, you can skip the stairs for now. Instead, just plan the space for them and use the area, for example, as storage for the time being. A straight staircase isn’t as suitable for this purpose as a half-turn staircase.

@K a t j a ... the planting beds are part of the road structure/road layout and therefore their location must be taken into account. See photo:
