The angle limit for vertical sightline and horizontal one is a maximum of 150 and 230 degrees, respectively. Accordingly, the designer maps out the horizontal sightline for the homeowners, thereby making them the center of this simple structure and allowing them to fill in various traces of their lives. The design lexicon, on the other hand, gets to expand beyond the sightline, elaborating on invisible nuances so as to endow the low-profile space with a unique taste—minimalist but not simple.
