LR window seat inspiration--but with thick cushion. (Note how backrest plane and then seat plane expand overall width without having to thicken the wall.) Napa Valley House by Steven Harris Architecture (Architect: Eliot Lee)
Deck ideas: Like the open stairs, flower box bench added to square deck with railings. (Not this big.)Would put chaise lounge and sitting chairs on deck. Two tone is nice, too. The stairs would lead to patio deck (table/grill).
