• The Office

    Located in the Leather District of downtown Boston, BIA.studio serves clients both locally and nationally, undertaking design assignments at scales ranging from large transportation centers and institutional buildings, to mid-sized renovation, expansion, and planning projects. Formerly design principals with large architectural practices in Boston, Bertaux and Iwerks have built distinguished architectural design careers in Boston, authoring numerous award-winning buildings in the city and region.

    Bertaux and Iwerks formed BIA in 2006 in order to explore new ways to deliver client and stakeholder value. The result of these explorations is Outcome-Driven design (ODd), a highly effective end-to-end framework for including diverse stakeholder perspectives in the design process. ODd has been implemented on numerous projects and has become a highly effective tool for engaging stakeholders and enabling group decision-making.

    Drawing on innovation techniques developed in other creative industries, ODd equips project participants with a methodology for maximizing project potential. Understanding stakeholders’ desired outcomes provides the key insights needed to create truly responsive design solutions.

    ODd has been fully integrated into our practice and is an indispensable part of the design process. The concept of distinguishing outcomes from actions has proven a powerful framework for seeing more options and resolving differences.

  • Leonard Bertaux

    Leonard Bertaux, AIA is a co-founder and principal of the firm. Over his career, Leonard Bertaux has focused on planning and design of academic, transportation, commercial, municipal, and residential projects throughout the north east.

    With an educational background in physics and architecture, he leverages his passion for improving the ways buildings work to create high performance structures that are energy efficient, resource wise, and people centered. Focusing on ways to move architecture to net-zero energy use, his philosophy is to maximize passive building strategies to reduce energy need while incorporating cost-effective renewable energy solutions to further enhance energy independence. Leonard is a leading practitioner of sustainable design and a LEED Accredited Professional (LEED AP) with the U.S. Green Building Council’s Leadership in Energy and Environmental Design.

    Leonard’s innovative design work has been recognized by numerous design excellence awards, most recently for the Bridgeport Intermodal Transportation Center, which has brought new vitality to the city’s waterfront. Prior to forming Bertaux+Iwerks he was a design principal with the Wallace Floyd Design Group for 14 years.

  • Chris Iwerks

    Chris Iwerks, AIA, is a principal and co-founder of the firm. Over his career, Chris Iwerks has advanced outcome-driven methodologies to help clients and user groups articulate essential goals and explore innovative design solutions. His collaborative approach has been applied to a wide variety of project types, encompassing architecture, experience design, environmental graphics, marine environment design, master planning, software design, and the creation of outcome-centered methodologies for decision-making.

    In architectural design, Chris Iwerks’ portfolio includes nationally recognized projects for civic institutions, transportation, education, and research. His efforts have been recognized nationally and locally for design excellence, including receipt of the highest architectural achievement in Boston — the Harleston Parker Medal for “the most beautiful building in Boston”—awarded for the design of Vent Building No. 7 at Logan International Airport.

    In the arenas of environmental graphics and experience design, he has developed projects where deep systematic thinking and empathic design intersect. He has led large-scale projects for the MBTA’s new system-wide wayfinding program, exhibit and experience design for the New England Aquarium and Zoo New England, and environmental graphics projects for the Woods Hole, Martha’s Vineyard and Nantucket Steamship Authority, UMASS Lowell campus, and the Greater Bridgeport Transportation Authority.

    As an educator, Chris Iwerks has taught design studios at the Boston Architectural College, Rhode Island School of Design, and Harvard Graduate School of Design.

    Professionally, Chris Iwerks has served on the Board of the Boston Society of Architects, and was elected to terms as the BSA Commissioner of Design and the Honors and Awards Committee. He also co-chaired the BSA Executive Director search in 2012.

    Throughout his career, Chris Iwerks has been an advocate for integrating sustainable design strategies into his projects and was among the first in the country to become an Accredited Professional (LEED AP) with the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED).

    His current focus is on the development and implementation of outcome-driven design techniques. This methodology, widely used in product and service design, is new to architecture and offers an improved process for framing project criteria around the important desired outcomes of stakeholders.
