ᐅ Opinions on Single-Family Homes with a Secondary Suite Floor Plans

If that’s not building land, you can’t really compare it 🙂

Actually, you can, since there are residential houses on all of it.

It’s true that the children’s rooms are included in the upper floor of the granny flat. If you added more of them, the entire roof shape would change, and it wouldn’t be cheaper either, because you would then have to comply with certain building regulations or planning permissions again.
Bungalows, for example, like the granny flat here, may be a maximum of 4 meters (13 feet) high and must have a roof pitch of 40° if I’m not mistaken.

Well, we don’t know your planning permission details. The information you’ve provided is quite limited. And in my opinion, you might be mixing up some things. Maybe take another close look.

Yes, then the roof shape would be completely different. So what?

What does the use of the roof have to do with the planning permission? If you’re allowed to build two roofs, then logically you should be allowed to build just one.

But if money isn’t an issue and the rest of the house is enough for you, then just enclose a bit more unused air space. The carpenter will be happy. Maybe you’ll need him for something later – who knows.

I think the latter is likely, especially considering your unusual reference to floor area ratio and plot ratio. Please tell me the municipality and the zoning plan designation so we can look it up. Different height limits, etc., for single-story and multi-story buildings usually apply to different building zones.

Which storage room is unusable and why?
I have never really seen it as a disadvantage that a child’s bedroom faces northeast.
I can’t quite imagine it right now, sure, it doesn’t get direct sunlight. But with daylight, it’s bright enough—especially with a window that is 1.60 x 1.60 meters (5.25 x 5.25 feet) in size.
The dining table is there for eating when guests are over, or possibly in the evening when the children are older.

I don’t like breakfast bars, which is why the table height is like that. The narrow table in the kitchen is for a quick breakfast in the morning without having to clear everything into the living/dining room.
What exactly do you mean by no direct connection between the living units?
Separate apartment and main house? That was important to me—that they are separated and you can only enter through the entrances to the houses. At one point, there was talk about building a door to the separate apartment from the utility room, but I was immediately against that. 🙂

The narrow hallway on the upper floor: what do you want to put in there? A cleaning supply cabinet would be too deep.

You will need much more light in the northeast-facing child’s bedroom. In the late afternoon, it can often be too dark for homework, even with daylight.

Ah, the dining area is intended as a formal living space. I still prefer a practical kitchen-living area instead of a makeshift solution along the kitchen counter.

The grandparents are meant to look after the children sometimes—whether in the evening, after school, or when a child is sick. They will also occasionally need some help. Do you really want to go outside in all weather conditions? There are even multigenerational houses that have a planned common area. Whether you want that is a personal decision—it definitely has its benefits. A connecting door is a must and doesn’t limit privacy.

Different heights, etc., for single- and multi-storey buildings typically apply to different building zones.

1. Building Heights The reference height point for determining the building height (finished ground floor level, ridge height, eaves height) is the intersection of the centerline of the adjacent public road surface—i.e., finished road surface—with the extended centerline of the respective building plot running perpendicular to the public road surface (plot axis).

1.1 The height of the finished ground floor level at the center of the building, measured from the reference height point, must not exceed 0.5 m (approximately 20 inches).

1.2 In the part of the planning area where the groundwater table (HQ) has been adopted as purely informative, ground levels of private building plots may be raised up to 31 m (102 feet) above sea level (normal zero, NN), so that the finished ground floor level lies above 31 m (102 feet) NN. The elevation must be constructed using materials suitable for surface water infiltration.

1.3 The eaves height of buildings, measured from the finished ground floor level to the intersection of the outer edge of the rising masonry with the roof covering, must not be below or above the following values:
- For roof slopes under 30°: minimum 4.00 m (13 feet 1 inch) to maximum 5.80 m (19 feet)
- For roof slopes over 30°: maximum 4.00 m (13 feet 1 inch)

1.4 The maximum building height (ridge height), measured from the finished ground floor level to the ridge line (highest point of the roof covering), must not exceed 9.00 m (29 feet 6 inches).

In the northeast children's room, you will need much more light. It tends to be too dark in the afternoons for homework under natural light.

Ah, the dining area is intended as the main living room. I still recommend a sensible open-plan kitchen without a makeshift solution attached to the kitchen counter.

The grandparents are supposed to look after the children sometimes—whether in the evenings, after school, or when a child is sick. They will also occasionally need some help. Do you really want to go outside in all weather for that? There are even multi-generational houses with a planned shared living area. Whether you want that is up to you—it definitely has its advantages. A connecting door is a must and does not limit privacy.

The storage room on the upper floor is 1.35 meters (4 ft 5 in) wide and 3.50 meters (11 ft 6 in) long up to the 2-meter (6 ft 7 in) line. I think quite a lot fits in there: suitcases, vacuum cleaner, cleaning supplies.

As for the entrances, I completely disagree. A connecting door is an absolute no-go… What’s wrong with leaving the main entrance, walking 6 meters (20 ft) across the covered area?

Why not? It’s only a few meters (yards), so it should be manageable.
I wouldn’t build an internal connection either.

Suitcases, vacuum cleaner, cleaning supplies.

A lot does fit, yes. But whether it can easily be taken out again is another question. 😉 It will be possible, but not easy to carry bulky items like a decorative box or suitcase past a cleaning shelf.

The kitchen can certainly be the heart of a home. It should be. But in this case, it isn’t—it’s more of a walk-through room, basically just a circulation area.
As the builder, I would be here with my plan exactly for that reason: to realize this (since I didn’t see it myself) and to take control, to make changes with a new design where the kitchen truly becomes what you want it to be: a central gathering spot.
