After a minifig-size replica of my apartment, I decided to make a microscale replica of the building that contains my apartment. I had that project since some time, and a challenge on the Lego thread of the hardware.fr forum was a good opportunity for that.
Photo of the actual building:
Captures from Google Earth, giving a better view for an easier comparison:
Edit: update with alternative roof tests made from comments received...
with red 45° slopes:
with tiles on the 33° slopes:
Maybe it would look good with dark red 45° slopes, but some required parts do not exist, and the roof is too high with such angle.
The visible studs instead of tiles help to keep a Lego style for the whole set.
So in the end I still prefer the first version.
