Interior design, and exterior design for that matter, always takes inspiration from styles found right across the world. Sometimes it is a nod to the design ideas of the past that are perhaps missing in modern architecture. Sometimes it is a celebration of the heritage of the area or community. Other times an internationally-inspired décor is a reminder of travel and fond memories.
This all goes a long way to explaining why many people like interior design with a French twist. Some like the classic looks of Parisian themes and want to emulate them. Some may celebrate local heritage by enhancing the appearance within a once French community. Others may want to recreate the look of a hotel or retreat from a family vacation.
