What we Do

United Excel Design provides architectural design and planning services centered on creating exceptional healthcare facilities to meet the design goals of our clients.

Our design process is focused on enhancing the patient care experience while providing a comfortable staff working environment. Key aspects of our approach include incorporating evidence-based design principles to reduce patient stress, configuring department layouts for more efficient operations, and ensuring infection control for patient safety.

We recognize that communication and collaboration with our clients is an essential part of the design process. Utilizing technology such as virtual reality and collaborative BIM software we can better communicate and coordinate ideas throughout the design process.
