What it is

I'm not sure, how the lighting is set up, but the black streaks seem to be coming from the window panels. If your light source is small or close-by it will create harsher shadows. There also seems to be some light bleed. This [this video] should help you with most problems when doing archivis in eevee

Your expectations may be too high for a 4k image. Your benchmark of 1 minute for the BMW is very good. Note, however, that the image is rendered with only 35 samples and at 50% size. If you increase the size to 100% the render time will quadruple! Increase the size to 400% and it will be multiplied by 16 again. That's 64 times longer for 400% than if the size was 50%. This turns one minute render time into one hour! On the other hand, your scene is an indoor scene. Such interior scenes need much more samples to get rid of the noise. That's because the light only comes through the window or door and bounces in the room. More samples increase the render time. Light portals can help a bit ( Wha
