Our focus on, light fixtures, lamps, custom made tables, mirrors and traditionally hand made upholstery has created a highly regognized level of quality.  


Central to the company's aesthetic is a deep appreciation for unique hand made custom built furniture and decorative elements that are accented by richly layered hand made custom finishes.

We are committed to working exclusively with highly skilled local artisans in order to provide the highest and durable quality for personalised interior design projects. Our sources are mostly of high end traditional European inspiration.
