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)
Murphy bed idea for guest room, but add second "foot" that turns into desk further down the bed. Store work items and craft items in cabinet. Also, embed lights in top "foot," to shine down on desk, just like ones that shine on bed.
