What We Do
LAB was established in 1999 and has completed a broad range of projects, including urban design, master planning, interiors, renovations, and new buildings. We’re most interested that our projects serve their immediate users and communities, and respond sustainably to their environment through sound construction and careful planning.
We want our buildings to create lasting impressions in the way they fit their neighborhood or site, capture the sun or view, or feel underfoot. We’re interested in the experience of the building and the place, both the sculptural form of the construction and the passage through the building’s landscape. Most of all, we want our buildings to have meaning — that comes from a response to context, environment, program, and architectural inspiration!
Who We Are
Brian Harner and Leonardo Sarli are registered architects in Virginia and the design principals at LAB. Over the course of our practice, we have invested heavily in our community, serving on multiple commissions, task forces, community associations, and working groups. Our buildings are of their community, projects that fit their surroundings.
Our master planning and urban design work are forward-looking, and broad in scope, with significant work in regional transportation and commercial center revitalization.
Brian’s experience over the past 20 years includes both private sector development and public-sector planning, with mixed-use commercial projects, community buildings, historic preservation, design guidelines, and transportation planning projects. Brian is a former chair and member of the Arlington County Planning Commission and has also served on the Arlington County Public Facilities Review Committee, responsible for the review of Arlington’s public buildings, including schools and recreational facilities. From 2012 to 2015 he chaired Arlington County’s Realize Rosslyn planning effort to devise a new sector plan for this important commercial center in Arlington. Brian has also been a U.S. Artist in Residence in Mexico, sponsored by the National Endowment for the Arts, for his studies of Spanish Colonial town planning in Mexico’s mountain villages. He holds a Bachelor of Arts in Economics from the University of Michigan, and a Master of Architecture I from the University of California Los Angeles.
Leo’s dedication in the office to architectural design, building technology, research, and construction documents has ensured high-quality and error-free construction of more than 50 buildings during LAB’s 20-year practice. In addition to the office’s architectural work, Leo also develops graphic design and layout for individual projects and manages all office production. Leo is a member of the Arlington Commission for the Arts and is currently chairing the Arlington County Cultural Facilities Task Force. He has served as a member of the Courthouse Square Sector Plan Working Group, the Four Mile Run Joint Task Force in Arlington, and the Public Spaces Master Plan. He is currently serving on the boards of Bowen McCauley Dance Company and the Arlington Forest Club. Leo holds a Bachelor of Architecture Degree from Andrews University.
LAB has been the recipient of several Arlington County historic preservation awards, and was part of the design team receiving a National AIA Honor Award in Urban and Regional Planning, for their work on the Burnham Place air rights development at Union Station.
