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.

We are also used to having a relative living with us directly, so I don’t see that as a problem.

It would really be a shame if we build alone—and then she would say: Oh, I wish I had…
When thinking it over, switch perspectives several times, plan a nice house for the family and then plan a separate apartment where you would like to live yourself. With two comfortable units, everyone should be able to live peacefully, and if one person doesn’t want to live there, another can simply move in.

And because I like the idea so much:
If she doesn’t want to participate—we’ll build with a granny flat anyway—maybe a bit smaller.

I would set a deadline for her, for example, Epiphany, by which she should decide yes or no. And if she doesn’t join in, cancel the all-in-one solution and build a house for the core family.

That’s exactly how I started again. I always end up with a house about 7-8m (23-26 feet) wide. Next to it, only a 4-5m (13-16 feet) wide apartment fits.
Most catalog floor plans have a study/guest room on the ground floor that we don’t actually need.

Done by Christmas

We want to build it together like this and have decided that the granny flat will be placed on the west side. That way, she gets a larger garden where the morning sun already shines from the east. And she has a separate entrance. So the entire half of the property basically belongs to her.
Without us having to walk back and forth or past each other.
This also makes the main garden a nice, large area instead of a narrow strip.

So approximately like this:

A simple rectangular gable roof house about 12.5x11m (41x36 feet) with a small extension/bay window, either to widen or lengthen it.
I’m missing some ideas for the granny flat now.
It should have an open kitchen: two-line kitchen with an island.
You can actually plan that pretty well as a long, narrow space, right?
But what about placing the sofa in front of the window/garden?

And for the main house, the garage blocks some windows.
A kitchen without windows, or rather the large living room next to the garage?

I’ll send two pencil sketches later.

Do I always have to rotate it so that north is at the top?

These are just some rough sketches, not accurate to the centimeter.
I don’t have exact measurements for the bathrooms, kitchen, or utility room yet.
But the furniture shown is the existing furniture.

This was attempt 1.

While drawing a standard floor plan, I realized that the front office could simply be assigned to the granny flat.
The kitchen doesn’t have a direct window.
The garage stays! This will not be a carport, in case anyone wants to suggest that.

Granny flat: The mother liked this version best, arranging the common room that way.
I think it’s a bit unfortunate that the couch would be placed right in front of the window.

Option 2 with a side "extension"

This should be better for the south-facing sun garden.

Now the living room is located in the corner next to the garage.

Accessory apartment:
Is it possible to design it like this?
You enter the open-plan area between the TV and the sofa?

You still haven’t made any progress. The upper floor is missing. You should start with that. As previously suggested, a slightly smaller size. Good to know that the first decision has been made. The position on the plot is, after all, clear.
