About THE TEAM

Karen Oriana Fellner grew up in South America, watching her dad - a TV producer and photographer, and her mom - a journalist and teacher, work really hard and loving their work. She moved from house to house, apartment to apartment; where she captured memories of neighborhoods, rooms and living rooms that she liked to explore - the stained glass at the double height staircase, the blue mosaic in the kitchen countertop and a row of hanging ferns. The little things that made each place a special one.

Karen’s interest in architecture and design has been always there. Her mom owned several encyclopedias, one of them on modern homes and furniture, and accent wallpaper, which she liked to read over and over. She watched the construction of a school from her living room balcony, which sparked her interest in the construction field. She wanted to know how buildings became buildings. The balcony had an italianate balustrade, the roof had Spanish red clay tiles and the fence had a Victorian wrought iron style. In school, she excelled in math and physics, she loved art - she was into Modigliani and Guayasamin.

She entered Architecture School at the State University in Guayaquil, Ecuador and after 2 years she moved to New York City for an opportunity to study Business Management. She lived in the tree-lined Park Slope, Brooklyn and after obtaining her Business Management degree, she realized there is no better place to study architecture than New York CIty.

Karen is a registered architect in New York State and an active American Institute of Architect (AIA) member, and holds a Bachelor of Architecture from The City College of New York/CUNY. She has been certified as a LEED Green Associate and is currently working on obtaining the LEED AP Homes certification.

She has sixteen years of experience in the architecture and design fields designing residential projects, single-family houses, apartments, K-12 education buildings, high end corporate interiors, retail and private residences in NYC, New Jersey, and Westchester County, NY. She collaborates with owners, engineers, contractors, project managers, tenants, manufacturers and vendors to achieve all project goals. Her work at Gensler & Design Republic have provided a solid foundation to the areas of Workplace interiors, interior design, and FF&E. Her work at SBLM Architects helped me gain experience in K-12 NYC SCA, public, private school and university projects in NYS. Her work at JWA Architects & Lind Design in Westchester introduced her to the design & construction of single-family homes & commercial spaces in Westchester, NY and beyond.

Karen works closely with clients, vendors, fabricators, contractors, engineers, lighting and audiovisual consultants, and interior designers, while managing all phases of work. She believes that the project starts at the introductory meeting, listening to their needs and wants and engaging the owner in the design process at an early stage, from their input in budget, schedule, and programming, to selecting finishes and reviewing contractors’ bids together. She conducts surveys herself to understand all existing conditions at the start of project, allowing her to provide accurate design advice. She enjoys conducting construction visits to review the project progress and address field conditions on the spot. The end result is to create spaces that are beautiful, functional, and budget friendly. Her diversity, communication, collaboration skills, and attentiveness to the clients’s needs enable her to lead multiple projects at any stage of a project, while ensuring overall project success.
