200m2 single-family house for 4-5 people without a basement on a narrow plot

Hmm... the AB on the upper floor is superfluous if the utility room is there. I don't like the bedroom. Or rather, it depends on what is supposed to go into the walk-in closet. And how is the bed supposed to be positioned? In front of a window? I consider 3.60 x 3.70 to be too small for a living room for possibly 5 people.

The AB somehow remained leftover, you could at most make a kind of second walk-in closet out of it (but it might be too narrow for that). The layout in the bedroom was intended like this, with a kind of clerestory window above the bed and a floor-to-ceiling window with a view to the north. Does that make sense? You could also make the bedroom a bit bigger at the expense of the office.

Instead of two terraces, I would build the house with a garage on the south boundary for the rather elongated plot – like your neighbors. Then you have a larger area of garden, lawn, etc. in the north. For sun even in winter, a seating area on the north boundary of the plot could be possible. You would just have to check the shadow cast by your house.

The problem with calculating the shadow cast is that the neighboring house to the west is not yet built; that is only a very preliminary plan. And as soon as the western neighbor realizes how much afternoon sun the 6m high boundary garage with roof of the next-but-one neighbor takes away from their north garden in autumn and winter, the western neighbor might still decide on a south garden (and cast a lot of shade into my north garden, just as I will do to my eastern neighbor if the house remains as drawn). It’s all a bit unpredictable.

Sonnenverlauf.de says that if I want reliable sun in the garden from October to February, I probably have to make a south garden (or sit outside the property). The rest of the months the north garden wouldn’t be that dark at all.

Der AB

I suspected that: 180 cm is too narrow for two real cabinets. At 60 cm you can no longer move between them.

FOR WHAT? Who sits in their garden in lousy temperatures? Sorry, but that is completely unrealistic. You use your terrace and take care of the rest, the planting. It may be that individually other things come into play. But you really don’t need any planning regarding the sun.

Hmm, the terrace in the north garden would definitely be almost completely in the shade during the dark season. I currently like to sit in the apartment in December in the midday sun on the south balcony.

Or am I just thinking too much about direct sun?
