About Us

STEPHANIE HALFEN, AIA, NCARB
Founder and Principal

Stephanie was born and raised in Caracas, Venezuela. She received an architecture degree from the Universidad Simon Bolivar, where she graduated Summa Cum Laude, and an Interior Design degree from the world-famous Parsons School of Design in New York, where she also graduated with the highest honors.

While studying for her first degree, she was awarded a commission to design a residential project in El Avila National Park in Venezuela. Turning the project into her graduation thesis, she was able to explore the dialogue between the landscape and architectural form in great depth, and develop innovative ways to design for life in a tropical climate. Upon graduating, Stephanie established her first architecture and design practice in Caracas in 2005. She also became an Associate Professor at her alma mater – Universidad Simon Bolivar.

Stephanie relocated to Miami in 2009 and founded SDH Studio Architecture + Design in 2012. Since then, SDH has become known for its design excellence and impeccable work ethic. It has also been named one of the top architecture and interior design practices in Miami, South Florida and the Caribbean.

Stephanie is a licensed architect in the State of Florida, is an active member of the American Institute of Architect (AIA) Miami chapter, and holds a National Council of Architecture Board Certification (NCARB). She also serves on several Architectural Review Boards.

She is especially interested in 3D modeling, rendering, construction drawings, and construction administration. She enjoys being able to be a part of the transformation of two dimensional elements into three dimensions on the screen and then on site. She also appreciates the collaborative and problem solving nature of the field.

Ana joined the SDH team in 2022, where she works on taking projects from schematic design to construction documentation.

Mouna Harbie was born in Lechería, Venezuela. She received her Architectural degree from Universidad de Oriente, Venezuela (2016). During her college studies, she participated in architectural contests and congresses. While studying she worked and helped develop several architectural and interior design projects.

She always had an interest in art and design, which initially sparked her interest in architecture. She also has a huge passion for photography, especially in architectural and interiors photography.

Always finding something new to learn every day keeps her excited to work harder.

She believes that simplicity always makes a difference.

Claudia Fleischman was born in Lima, Peru, and raised between Lima and Asunción, Paraguay. She earned her Architectural Degree in 2016 from Universidad Peruana de Ciencias Aplicadas.

As she started working, she decided to explore different areas and had the opportunity to work in a construction company, an architectural and interior design studio, and at a renowned artist’s studio.

While living in Lima, she started developing her own Architectural, Interior, and Graphic Design projects, providing design and build services. This made her truly enjoy being a part of every step of the process and connecting with clients.

A couple of years later, Claudia found herself moving to Miami and joining the SDH Team as an Interior Designer.

She believes that the spaces we inhabit directly affect our well-being and that architecture and design are tools for personal and cultural development.
