Upscale Medical Office on Fifth Avenue, NYC
Working directly with a fast-growing medical provider, In-Site interior designers created an upscale design for this Fifth Avenue medical office in NYC as a prototype which could be easily integrated for future locations. It was important for their brand to be contemporary and set itself apart through design, while being mindful of costs by selecting from the landlord’s standard finishes, using select key elements of customization for wow-factor.
