What STX Landscape Architects does

STX Landscape Architects is a Singapore-headquartered landscape architecture consulting firm founded in 1995 (originally as Sitetectonix) by Helen Smith-Yeo. The firm offers three core service lines: landscape architecture, masterplanning, and urban design. Its practice spans four project categories — residential (predominantly luxury condominiums), institutional (university campuses and educational facilities), commercial (corporate headquarters, IT parks, mixed-use developments), and hospitality (hotels and resorts) — serving both private sector developers and public institutions primarily across Asia-Pacific (Singapore, Malaysia, Thailand, India, Maldives) with selected international engagements in Canada, the Middle East, and North Africa.

The firm's technical differentiation rests on a design philosophy that integrates landscape with architecture through vertical landscape solutions (sky terraces, green walls, skyrise greenery), water-sensitive urban design, biodiversity considerations, and culturally contextual aesthetics inspired by natural forms and local heritage. This methodology is operationalized through a multidisciplinary team that combines conceptual design with technical delivery via CAD/BIM workflows. Marquee projects include Oasia Downtown Hotel (a CTBUH Best Tall Building Worldwide 2018 winner featuring a 'living cloak' of climbing plants), Sophia Hills (heritage-integrated tiered landscape design), NUS University Town, and Hindustan Unilever Headquarters. The firm has accumulated 100+ industry awards spanning FIABCI World Prix d'Excellence, IFLA Asia Pacific, MIPIM Asia, CTBUH, ULI, and Singapore Landscape Architecture Awards.

STX operates a professional services business model with project-based pricing determined by scope and complexity (not publicly disclosed). Revenue is generated through direct engagement with enterprise clients, including RFP processes for public sector work and relationship-driven sourcing for private developments. The firm maintains a small to mid-size team (11-50 employees) led by three principals (Helen Smith-Yeo, Patrick Morello, Sherman Stave) with Harvard and University of Guelph credentials. In June 2025, STX joined Toronto-based landscape architecture firm LANDinc, creating a combined Asia-Pacific and North American platform while retaining the STX brand. Marketing is conducted primarily through portfolio-based content marketing, industry publications, and conference participation rather than paid acquisition channels.
