ᐅ Roof Overhang on a Gable Roof as a Protection for the Building Façade?

We are currently building a single-family house. The roof is designed as a gable roof with an 18° pitch and a 30cm (12 inches) eave overhang.
Personally, I think a roof without an overhang looks more modern. However, my architect believes that the eave overhang protects the house from weathering and is more cost-effective because it requires less complex sealing.
I find it hard to imagine that a) a 30cm (12 inches) eave overhang actually protects the facade and b) that the house would require significantly more sealing work and therefore higher costs without it.
What is your opinion on eave overhangs?
Thank you very much and best regards!

I am currently planning a gable roof with a 38° pitch. The eaves will have an overhang of 64cm (25 inches), and the gable overhang will be 36cm (14 inches). Previously, I had planned for a 87cm (34 inches) overhang at the gable, but my architect advised against this for aesthetic reasons (mushroom effect). Incidentally, I also saved 1,980 euros. However, I didn’t want to reduce the overhang any further, as I believe no or very small roof overhangs give the impression that someone was trying to save too much...

- Only reinforced battens, meaning no visible purlins where birds could nest
- Enclosed space directly under the roof
- 50cm (20 inches) all around
I have not seen this in any other house so far; usually, these "roof boxes" were very thick because of the large beams. Is this especially expensive or complex here? My planner never mentioned this option.
Is there a specific term for this type of construction?
