our team

Holly Batt : Principal

Holly is co-owner of Batt + Lear. She studied both dance and architecture at the University of Washington, receiving a Master's Degree in Architecture in 2001. Though Holly sometimes teaches in the Architecture program at the University of Washington, these days, Holly spends part of her week at Batt + Lear and part of her week raising the next generation of Batt + Lear’s team – Maggie and Hammet Lear. Her work at Batt + Lear is focused on materials research, lighting technology research and interior design. Holly is also a professional dancer with the DanceJenkinsDance!!! company, and she leads Batt + Lear’s collaborations with the choreographer, Pat Graney.

Jason Lear : Principal

Jason Lear is founder and co-owner of Batt + Lear. Jason believes that we have the opportunity to make our 130 million existing houses, and untold numbers of commercial buildings significantly more energy efficient than they are, and, in the process transform them into a part of our environment that will thrive, and contribute to their surroundings, for many generations. He does not believe in a Silver Bullet approach; rather, he recommends treating a building as the complex system that it is and using simple systems, and excellence in construction, to make that building work better. He emphasizes the importance of both a holistic approach to building and attention to detail in every step. Jason loves building green and has a contagious passion for sharing that love.

Jason Lear received a Bachelor's degree in Architecture and International Studies from Yale University. Recently, as a member of the Northwest EcoBuilding Guild’s Regional Education Committee, Jason has spearheaded a collaboration between the Guild and South Seattle Community College that seeks to provide college credit for field-based, hands-on education modules, for existing and new practitioners in the green building field.

Marketa Kockova : Office Manager + Landscape Designer

Marketa runs the office and looks after daily accounting and reporting. With her keen knowledge of sustainable landscaping, she is the heart and soul of Batt + Lear’s landscaping team.

Alex Pfeiffer : Designer

Alex received his MArch from UW in 2001, and has since been a part of many high-profile projects including Nintendo's LEED Gold-certified North American headquarters in Redmond. Alex has also enjoyed remodeling Seattle's King Street Station and several schools, including the complete transformation of Nathan Hale High School.

Jan Kunasangeamporn : Designer

After receiving a degree in Civil Engineering, Jan relocated from Bangkok, Thailand to Seattle to pursue graduate degrees in Architecture and Construction Management at the University of Washington. Over 15 years, she has developed a strong relationship with a tight-knit community of individuals who share a deep appreciation for beautiful things, diverse cultures and life, which has greatly influenced her design approach and art. Jan's natural understanding of space and proportion is evident in the many residences she has worked on at Batt + Lear. She has also worked on a range of public and private projects in and around Seattle before joining Batt + Lear in 2005.

Walter Goodwin : Construction Principal

Walter has a degree in philosophy, the study of value and thought, and psychology, the study of human living and behavior systems. He made the decision early on to take the understanding from his studies and to apply it on a practical level in two ways – through education and through building design and construction. Walter has been a teacher and builder for over 30 years. He is dedicated to sustainable living and building principles and applies them in all phases of his work and life. Recent successes includes multiple Built Green 5-Star and LEED Platinum projects. His body of work includes successful residential and commercial projects in France, England, Germany, West Virginia, Maryland, Virginia, Washington, D.C., New York, Massachusetts, California, Oregon and Washington.

Energy performance and building science are important elements to sustainable building design and construction but they only work if the technology is used by dedicated and educated individuals who place the future health and well-being of our world ahead of material gain and personal recognition. We all need to strive to be awakened to a level of intelligence that incorporates our collective future on a grand scale and to the power and spirit of conscience that guides and encourages good deeds, meaningful action, fun and responsible behavior.

Imagine a perfect world – and then work to create it.
