Worklounge 03- Vietnam Co.

What Worklounge 03- Vietnam Co. does

Worklounge 03- Vietnam Co., Ltd. is a boutique architectural and sustainable design firm headquartered in Hanoi, Vietnam, established in 2010 by Hiroomi Takemori as a 100% foreign-invested subsidiary of the Tokyo-based practice worklounge 03- (founded 2003). The firm employs between 1 and 10 people and delivers full-service architectural design across residential, hospitality, cultural, educational, and public building typologies, with active engagements in Vietnam, Japan, Korea, and Turkey. Signature work includes the award-winning Step House resort villa in Vinh Phuc, the Lang Son Province Administration Building (25-story competition winner targeting 45% energy reduction), the Vietnam Japan University temporary campus, the Japan Foundation Library in Hanoi, and the Kimono Restaurant interior. The firm specializes in hot-humid tropical climate architecture, combining traditional Vietnamese woodworking techniques with computational environmental analysis (Revit/BIM, Rhino/Grasshopper) to deliver passive cooling and solar shading solutions, and offers separate LEED, LOTUS, and EDGE green building certification consulting through co-founder Tim Middleton, a LEED AP, LOTUS AP, EDGE Expert, and VGBC Board Member.

The business model is project-based professional services: clients engage the firm directly for commissions (typically secured via architecture competitions, institutional relationships, and reputation) and pay professional design fees tied to project scope. There is no productized software, no marketplace, and no intermediaries — every engagement runs through the two co-founders. Revenue is not publicly disclosed, there are no funding rounds, and ownership remains entirely with the founders, with no external institutional capital or parent company. Marketing and client acquisition rely on international architecture media (ArchDaily, Designboom, Nikkei Architecture, KJ, Shin Kenchiku) and award circuits (A' Design Award, HOPE Awards, 2A Asia Architecture Award, Ashui Awards) rather than paid channels. The firm's long-term positioning hinges on a niche combination of Japanese architectural sensibility, deep Vietnam-localized climate expertise, and green building credentials that have produced a disproportionately recognized portfolio for a sub-10-person practice.
