You don't have to have a 50's home to have cool retro modern front doors. The optimistic colors and unique window designs make these two choices a good way to give your home a nice face lift with out breaking the bank. The Crestview collection gets it's inspiration from David Erwin's take on the 50's but adds updated solid wood core and high efficiency windows and still manages to keep the price range $800 – $1200 and deliveries in 6 to 8 weeks.
The Snickarper collection from Sweden has a distinct look and even adds some flair to their collection of retro modern front doors. I guess the 50's was a stylish time over in Europe as well and Snickarper has a very diverse collection of residential front doors in a wide variety of finishes that really make a bold statement. I really like their contrasting window trims and linear details as well as the simple hardware. Snickarper also makes interior doors and garage doors as well to round out the complete look of your home.
