I'm curious to see what will come out of this in the end.
If you first have to bring subwoofers, southern children, tumble dryers, and short house connections under one roof: then in my estimation, it's waiting for Godot.
In your floor plan, I find the living room very small.
You're mistaken there, probably the generous dining table confuses you.
The gable roof is much more charming and modern than the tall hip roof, which is not proportional to the building at all.
In reality, this is far less dramatic than in the drawing, and even with hip roofs, it's subtler than with gable roofs of the same pitch.
I would simply position the house at an angle with a standardized garage,
Anyway, definitely with a standardized garage – any potential parallel offset settles much more advantageously in the carport in between.
Ceterum censeo: a bungalow is a house type whose domain – apart from the special case of a wheelchair-using family member – is the couple with completed family planning (whether childless, children already out of the house, or willingness to move in case of more children). But the need for a child’s room on the ground floor automatically brings additional attic floor space with it and is thus its own strongest argument against not converting the attic. With such small children (2 years / 7 months), I also see a shared room as sufficient for quite a while and consider the option of later separating them on different floors so they can avoid each other (or then moving the bedroom upstairs) worth considering.
