alloy design group


BS of ARCH '01 - University of Virginia
MArch '05  -  University of Washington

Mark Haizlip is a native of the Pacific NW and has long been interested in the built environment, the natural environment, and the relationship between the two. These early interests took him to the University of Virginia where he received his undergraduate degree in Architecture. Following graduation he worked as a field engineer in Washington DC and then moved back to Seattle to work on his Masters degree in architecture at the University of Washington. This is where he met Greg Squires and ultimately joined up with him to collaborate on their thesis project; a small design/build project for a non-profit organization. Shortly before graduating he joined Pb Elemental, working there for the next five years with the primary role of establishing the single family residence division. Following his departure he teamed up with Greg Squires to form alloy design group. They have been collaborating ever since with the intention of producing work that positively influences our environment, both natural and built. When he doesn't have his mind on architecture, he enjoys spending time with his family, coaching basketball, and exploring the great outdoors.

BArch ’14 – University of Southern California

Corey Koczarski, born and raised in Woodinville, WA, moved to Los Angeles to attend the University of Southern California. Five years later, he graduated from the USC School of Architecture with a Bachelor of Architecture, and a minor in Cinematic Arts. His interests in both fields lie in the visceral and spatial relationships provided by both media. His fifth-year degree project involved a yearlong pursuit of the thesis he presented in a written work entitled, “Toward a New Master Builder”. The manifesto serves as a reflection of his pragmatic attitude, his approach to architecture, and as a document outlining improvements to the methodology of architectural discourse.

He has previously collaborated with the USC Solar Decathlon Team that worked towards the 2013 competition at the Orange County Great Park in Irvine, Ca. Corey currently spends his time pursuing all aspects of design, photography, the outdoors (including Seattle’s rain), and has a passion for craft and the process of making.


Certified Electricians License (UK) ’03
AAS: Architectural Engineering Drafting ’15 – NSCC Seattle

Dermot was born and raised in Ireland and has lived in the U.S. for almost 10 years. It was in his home town of Dublin where he first discovered his love for building and architecture, citing the many historical castles, ancient ruins and cathedrals of Ireland as his inspiration. After successfully completing an electrician apprenticeship, he continued to work in the electrical industry for many years. His experience focused mainly on wiring single family homes and residential remodels. Dermot emigrated to the U.S. in ’06 and settled in Seattle, where he met his lovely wife and started a family. During this time Dermot began working with a local building contractor, and oversaw many construction projects including single family residences, remodels and retail developments. Dermot then decided to transition away from construction and pursue an education in architectural and engineering drafting. He now enjoys the challenge of applying his construction and drafting experience into the overall design and implementation of architectural projects.

an alloy is the combination of distinct elements that creates an aggregate stronger than the sum of its parts. This essential concept guides the way we work. alloy design group is a design firm that believes collaboration is the key to every successful project. With each new opportunity we aim to create architecture that generates a sustainable built environment and inspires creativity.
