OFA Group provides comprehensive architectural services, including design and fit out for commercial and residential buildings, interior design, project management, regulatory approvals, and design only consulting. The firm leverages technology such as the Houzz platform for 3D visualization and is developing an AI enabled tool, OFA TransBIM, to automate construction drawings and code compliance checks. While its core operations are based in Hong Kong, OFA Group plans to extend its services into the United States and broader Asia markets. The company also began accepting cryptocurrency payments for its services in July 2025 as part of a digital asset treasury strategy.

Revenue is derived from four service lines: design and fit out, project management, application services, and design only. In the fiscal year ended March 31, 2025, design and fit out contributed $80,464 or 39.84% of total revenue, project management generated $64,684 or 32.02%, application services brought $39,883 or 19.74%, and design only services accounted for $16,976 or 8.40%, yielding total revenue of approximately $202,000. In the prior year, design and fit out represented $427,182 (80.51% of revenue), project management accounted for $58,551 (11.03%), application services totaled $44,873 (8.46%), and design only generated no revenue, with total revenue of about $531,000. The shift in mix reflects the company's efforts to diversify beyond its traditional design and fit out core. Additionally, OFA Group started accepting cryptocurrency payments for its services in July 2025, although this activity has not yet materially affected reported revenue.

OFA Group competes in a highly fragmented architectural and interior design industry where success depends on design quality, technological innovation, project management, sustainability expertise, and pricing. The firm identifies global players such as Gensler, Foster + Partners, Aedas, and Ronald Lu & Partners as its primary competitors, while highlighting its own competitive edges. These include its focus on AI integration through the development of the OFA TransBIM platform, its use of established tools like Houzz for 3D visualization, and its exploration of Building Information Modeling (BIM), virtual reality (VR), and augmented reality (AR) to improve design accuracy and client engagement. The company also benefits from an experienced leadership team comprising founder Larry Wong, who has over two decades of architectural experience; project director Keith Chong with similar tenure in project management; interior designer Meira Ho, noted for modern, client focused work; and structural engineer Ernest Wong, respected for solving complex structural challenges. Furthermore, OFA Group emphasizes sustainable and nature integrated design, citing projects such as the Tin Hau Temple that uses 100% natural lighting and ventilation, and maintains strong client relationships, with roughly 90% of its revenue derived from repeat or referral customers.

The company serves a diverse clientele that includes homeowners planning renovations or new builds, developers of residential, commercial, and mixed use properties, businesses seeking architectural design for offices, retail spaces, restaurants, hotels, and other commercial premises, and institutions such as schools, universities, hospitals, museums, and government agencies requiring design services for their facilities. Specific clients referenced in the filing are Yuen Long Primary School, Corporation Park Office, and Delta House Office. OFA Group reports having approximately 35 to 45 customers each year, with over 100 returning customers since its inception and cumulative revenue of approximately $7 million from those repeat clients as of March 31, 2024. Additionally, the firm notes that about 90% of its revenue comes from repeat or referral business, underscoring the durability of its customer relationships.
