 The firm was originally founded by Samuel J. Caudill FAIA, who was honored with the American Institute of Architects for his lifetime of architectural achievement. As a direct outgrowth of Caudill Gustafson and Associates, Z-Group Architects’ reputation as go-to, practical architects is realized through cost-effective, efficient, durable, functional, and attractive designs.

Currently led by James A. Gustafson NCARB and Seth Hmielowski AIA. Our continued commitment to community and client satisfaction can be seen in our collaborative spirit, energetic staff, and open work environment.

“In a strange way, architecture is really an unfinished thing, because even though the building is finished, it takes on a new life. It becomes part of a new dynamic: how people will occupy it, use it, think about it.” – Daniel Libeskind

“A great building must begin with the immeasurable, must go through measurable means when it is being designed, and in the end must be unmeasured.” – Louis Kahn

“As an architect you design for the present, with an awareness of the past, for a future which is essentially unknown.” – Norman Foster
