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.



BS of Arch '02  -  Washington University in St.Louis
MArch '05  -  University of Washington

Greg Squires was born in St. Louis, Missouri in 1980 and raised in Dallas, Texas. He returned to Missouri to receive a Bachelor of Science in Architecture from Washington University in St. Louis in 2002. Following his hands-on passion for becoming an architect-builder, Greg made his way to Seattle and received his Masters in Architecture from the University of Washington in 2005. His master’s thesis project, which built an outdoor classroom facility for a small farm in Seattle's Southpark neighborhood, was the first collaboration with Mark Haizlip, co-founder of Alloy Design Group. Before founding Alloy in 2009, Greg focused his work on the construction side of architecture and development. As the director of construction for Pb Elemental Architecture (05’-09’), Greg over saw the building of 120+ residential units within King County. These projects received numerous awards and accolades for innovation in design and efficiency. Greg founded Alloy Design Group in 2009 to create a firm with a practical approach to the design, permitting and construction of modern sustainable residential architecture


Registered Architect – Washington & Hawaii
BA History ’98 – University of South Carolina
MArch ’05 – University of Washington

While other 4-year-olds dreamed of being doctors, star quarterbacks, or even Superman, Tim told a local TV personality on-air that he wanted to be an Architect. The seeds of Tim’s “dream job” were sown in South Carolina at an early age in his grandfathers’ workshops and watching his father hand draft plans for an addition to his childhood home. A love for the smell of wood and making stuff followed him throughout childhood where he was an avid drawer and construction site bandit. His formal architectural education began with Jersey Devil Steve Badanes at the Yestermorrow Design/Build School in Warren, Vermont. It was in another design/build studio led by Badanes at the University of Washington when Tim first worked with Alloy-founders Mark Haizlip and Greg Squires. This experience proved that the three not only worked and played well together, but also shared a love of the collaborative process and well-crafted structures. Tim enjoys the collaboration that exists when all pieces of a project are actively engaged. He is a thoughtful and engaged teammate and enjoys interaction with the client and the communities where our buildings are located. Tim’s design experience includes residential, commercial and public projects. He has worked on a variety of building types - from single family residences and commercial tenant improvements, to primary schools and juvenile detention facilities. When he is not practicing his craft, Tim can be found strumming a ukulele on a hidden Hawaii beach or acting silly with his wife and 2 young children.

BS of Arch ’11 - Washington State University

Hana was raised in Seattle and devoted a great deal of her youth and adult life exploring art and architecture. Her appreciation for integrating design, building sciences, and the natural environment lead her to Washington State University where she received her Bachelor of Science in Architecture. After graduating, she developed her design and technical skills at an award winning firm that focused on single-family residential architecture, and a firm that specialized in multifamily projects and building envelope enclosures. Architecture aside, Hana enjoys spending time in the great outdoors, and has a passion for music.  



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 an architecture 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.
