The Lego Ideas Luxury Mansion is the newest addition of designs I have made.
It includes 3 Minifigures, 3 Balconies, 2 small gardens, A gravity locking floor system, 2 bedrooms, 1 bathroom, An office, A music recording area, 1 kitchen, 1 living room, and A lot of detail.
When I was building this I looked at many modern mansions in the hills of Los Angeles, I seen the grey mezzanine style element in a lot of real houses.
I believe this would make a great Lego set because it has a lot of detail, A lot of play-ability, and a lot of fun things in it.
