I always tend to focus on the interiors of a house, but the exterior is just as important. My best advice is to keep the outside classic and add a fun twist or pop that's easy to change. You can always paint a door to freshen up the look.
Here's some of my favorite exteriors that I have been loving.
Light grey and white mixed with a stained wood door. It's classic enough it will never go out of style.
Grey with light blue doors, this garage is such a great color combo.
Very traditional black and white home. With wall to wall windows to let in lot's of sunlight.
I love the pops of turquoise in this exterior. It adds a beachy feel and is stunning!
The landscape design is equally stunning as the architecture.
