As I was browsing on Pinterest, two things caught my eye: symmetry and/or colour.
On the right, seasonal decoration and a wreath add a warm touch .
Bold front doors are not the norm here in Norway, probably because the houses themselves are colourful. Traditionally, houses are red, yellow or green. White near the shore. However, the last years, the trend was to paint them white or grey and that's why I would definitely go for a bold colour for the front door . What is the norm where you are living?
