Floor plan of a single-family house approx. 170 m² on a narrow 750 m² plot

Do-it-Yourself: Template of a prefabricated house provider’s plan [...] Do the room sizes seem reasonable?

Why don’t you attach the garage to the house?

Just name the base model (without a link!). The catalog designs are usually quite usable because they have been tested. Therefore, they generally remain sensible if not altered drastically. Where exactly have you made adjustments, and what was your motivation?

Now don’t encourage someone to do that – I’m grateful for everyone who refrains from that nonsense.

Why? If I could plan freely, I would always place the garage directly next to the house, with direct access to the utility room. What do you see as an argument against that?
