The iNTA 2025 First Annual Design Competition invited developers, design professionals, and academics to submit innovative tropical and subtropical housing projects and research in four categories: Sustainability, Resilience, Action-Oriented, and Historic Preservation/Adaptive Reuse.
Focusing on the conference’s theme “Housing Futures in the Tropics: Resilience, Sustainability, and Action”, the competition received entries from all over the world that explored solutions for climatic imperatives, problems, and opportunities in tropical and subtropical regions.
Congratulations to this year’s winners!

2ND PLACE
Kamp to Kampong, Banda Aceh, Indonesia,
Teo Rui Zhi Rachel / Student / National University of Singapore
Rachel Teo is a recently graduated Master’s student who cares about design that is grounded, intentional, and deeply connected to material craft. She believes landscaping isn’t an afterthought but the quiet backbone of good architecture—especially in the warm, humid, and wonderfully unpredictable environments of Southeast Asia.
Rachel has a soft spot for hands-on making. She enjoys 3D printing, product design, and woodworking/carpentry, where she can test ideas quickly and understand materials by actually working with them. She’s drawn to placemaking and humanitarian architecture, and she gravitates toward small, thoughtful projects that quietly create big, meaningful impact.

Metaamo + ʻIke Honua /
Leads: Matthew Bunza, James Miller, Xiaonuan Sun
Project Team: Kyle Altman, Jade Danek, Curtis Trueblood, Sang Pham, Purvangi Patel, Salum Rajabu
Metaamo is a process-driven, collaborative design practice working at the intersections of architecture, urbanism, landscape, and ecology, known for bridging cultural contexts and diverse scales. Based in Portland Oregon, but with satellites in Auckland and Hong Kong, its work spans continents and disciplines — from intimate residential spaces to large-scale urban planning — focusing on projects that uplift communities, honor cultural identities, and address resilience in the built environment. ʻIke Honua represents Metaamo’s research arm, blending rigorous academic research and applied practice; the design lab focuses on indigenous resilience across the Pacific.
