Hello everyone,

After reading a lot here and planning for three months now, I’m trying to get some help.
The plot is complicated, maybe a bit narrow to also fit a separate apartment on the ground floor.

We are unsure how to “split” the plot.
Who should get the west or east side?
Which street should the house face?
The 5.5 m (18 ft) setback area on the north side suggests itself as the driveway/parking area. Also, no one wants a north-facing garden.
We all want sunlight somehow, but with further construction progress on other houses (marked in red) and the low sun angle, hardly any sun reaches the southern area.
The separate apartment really only needs a sunny terrace (because mowing the lawn will get harder with age).

I’ve simply added the architect’s two drafts here.

And that’s why I currently have a real problem on the ground floor..
I can do that. For that, I now have the children’s bathroom above the living room?

Let’s wait and see what the original poster says about this.

I would design the granny flat with a flat roof. That way, you can plan a really large window by the staircase.

Even if one office is intended just as a hobby or backup space, 6 sqm (65 sq ft) feels quite small for 4 people.
Yes, budget is a factor, but now you’re proposing an expensive flat roof and large windows on the upper floor.

Of course, I’m open to other ideas, but I believe the first priority should be to design good and affordable living space.

Personally, I don’t find the entrance and bathroom in the separate apartment very appealing. The bathroom is too tiny; after all, there should still be enough space for an independent washing machine, or at least a barrier-free shower and the necessary clearances, possibly with a grab bar on the wall.
My situation is different from yours. I assume your bedroom doesn’t have 3 meters (10 feet) of usable wall space on the lower side of the plan? I try to plan for a 3 x 4 meter (10 x 13 feet) room where possible, and then there would only be space left for a very small 4 sqm (43 sq ft) bathroom. I would plan that bathroom in the main apartment, since the residents are still young and there are other bathrooms available, but not in the separate apartment.
What do you think? Can you manage to optimize that better?

I am still a fan of No. 79 (because of the dimensions and the adapted office)... However, the utility room, basically serving as an extended closet space between the two bathrooms, was better.

Why... @Hausmma once mentioned somewhere that having morning coffee on the terrace is actually important for the granny flat as well. And this east-facing terrace of the granny flat also gets southern sun.

The family terrace, on the other hand, is more suitable for me because of the possible western sun. I also prefer the exterior appearance compared to having to imagine a flat roof or a large sloped roof on the left side above the granny flat in the west.

Additionally, in post 79, photovoltaic panels can be installed on the south-facing roof area, and with a very shallow roof pitch, it is also feasible to cover at least the top row of the north roof.

Wow, you were really creative today.
I can barely keep up.

What can I say: this floor plan is almost exactly like our current house!
We would feel right at home (okay, currently it’s only 7 x 10 m (23 x 33 ft)).
And what I just don’t like is the long, dark, narrow hallway – don’t you have another idea for that? Maybe a different staircase design?

But you’ve also planned the upper floor quite small, haven’t you?

I find the 3 m (10 ft) west garden not very practical. With a hedge, only about 2 m (6.5 ft) width remains – so almost unusable.
Therefore, I might also suggest placing the entrance for the granny flat on the side.

Is the south side not enough?

Where do you see a long, narrow hallway? I’m actually not planning anything like that.

Ok, you’re right, I would have added a small wall between the kitchen and the corridor.
