Jeff,
You know me...less is better. As far as distinction, I think the best way to achieve that is to do in-house production of accessories as much as feasible. Water chests built of native stone, benches of native trees from the property, etc. Of course, there isn't much for materials on that perfect wind swept, ocean front dunesland we all dream of......although, the right polymer mixed with sand could be fun.
Hope you're well,
Joe
