Thanks for your nice comment! Those are sand set concrete pavers.

Beautiful windows! Are those Marvin windows? And what kind of reflective tint do they have? I’m considering similar windows for our new home. I would greatly appreciate your insight. Thank you.

Thank you! Those are Sierra Pacific windows, but Marvin are similar. I believe the windows were just low-e with no tint. The photograph may make the living room windows look more reflective than they actually are.
