Bonstra | Haresign ARCHITECTS has been engaged in adaptive reuse converting schools, churches, industrial and office buildings to residences and other uses since the firm was founded. Housing shortages in our region persist. Conversions of mid-century office building in urban and Inner ring ex-urban locations proximate to public transportation, walkability, and nearby amenities. Outdated office buildings, in need of complete renovation or replacement, offer a sustainable alternative to new construction that saves embedded carbon and energy, and reduces time to market for residential projects. Our new publication, reIMAGINED :: Office to Residential Conversions, offers insights into addressing inherent challenges and shows possibilities with successful projects, and is available to read now! https://www.bonstra.com/studio/design-line/reimagined-office-to-residential-conversions/

The Essen, located at 1801 North Beauregard Street in Alexandria, VA, converts a 1980’s 4-story, 124,545 square foot office building to multifamily residential use. The six-and-a-half-acre project site sits adjacent to a forested nature preserve. The complete residential conversion yields 119 dwelling units. The basement and terrace level spaces include both common area lobby/amenity space as well as residential units. Exterior modifications to the existing building include an entry portal, adjustments to a limited number of window openings, and balconies that articulate the façade and provide views of the preserve.

All of us at B|HA celebrate and wish you a Happy Black History Month! This month reminds us to always honor the Black and African American architects that helped build and shape our nation, and especially our home of Washington, DC.

We would like to remember titans John A. Lankford, the first African American architect registered in DC, and original architect of CITTA50, as well as Hilyard Robinson, the original architect of Carver and Slowe Halls. Named after George Washington Carver and Lucy Diggs Slowe, respectively, these converted Howard University dormitories wereoriginally constructed in 1942 as housing for African American men and women supporting the war efforts.

These incredible black architects and their peers left ever-present marks on our nation and capitol. We celebrate the rich history of their legacies, their work, and the importance of diversity in architecture and design.

Located in Silver Spring, Maryland, an existing underutilized county-owned civic center and auditorium are re-envisioned as Allium Place as part of the Veirs Mill Corridor Master Plan that better connects communities to improved transportation and urban infrastructure. Allium Place successfully addresses the “missing middle” housing stock by providing both affordable multifamily housing, and for sale condominiums and single-family homes. A total of 192 affordable housing units were delivered to provide new opportunities for cost-burdened families.

This year, Allium Place has been awarded the Innovation Award from the Maryland Affordable Housing Coalition, and Best Small Project (Under 200 Units) by the LAI George Washington Chapter Awards.

We congratulate our clients, contractor, partners, and our B|HA design team for their excellent work in creating this incredible affordable community!
