hi, houses built during the 19th century had two front doors...i know it looks kind of weird but there's a logical reason behind it. One room leads to a so called " keeping room" and the other leads to the living room.
The keeping room contains a large fireplace, tables and chairs, but this is not where you introduce your guests while the other door is only used for special occasion. Or normally, one door leads to a parlor room while the other to a family's private room.
Glad it's the 21st century...it means, one front door
But i bet you're house is one-of-a-kind!
