Clive Christian is probably more well known for being the company that sells the world's most expensive bottle of perfume.They also have a reputation for high end cabinetry based home interiors.
Most of their designs are based off of old world designs but done with a modern cabinetry layout scheme.
Something of note with most of their designs is that they incorporate three elements. Crystal chandeliers, lots of wood molding and mirrors. When you break that down these are relatively inexpensive materials available at any big box home improvement store.Crown molding either stained or painted to match the walls is a fairly easy project even a beginner could tackle. Basic cabinets could benefit from added crown or base moldings stained to match. Front molding and finials are also readily available and could be added to the front of cabinet bases or open shelving. Crystal chandeliers can frequently be found at garage sales, flea markets and house fixture reuse stores. Walls can benefit from frames made of molding that are mounted to the wall. When doing so on a painted wall, painting the frames to match makes them look built in. The bedroom pictured could be mimicked using a love seat and two wardrobes. A used hotel furniture warehouse would be an idea source for a pair of matching wardrobes or armoires. The heavy use of mirrors is another features that is relatively easy to recreate. Standard unframed mirrors from a big box home improvement store could be installed on the wall and framed out with the finish moldings to blend into the wall.
