Here are notable hotels in Sri Lanka that exemplify tropical modernist architecture (with architect or design notes and sources):

• Heritance Kandalama — Kandalama / Dambulla. A cliff-hugging resort by Geoffrey Bawa that integrates the building into the landscape and rainforest reservoir — a signature example of Sri Lankan tropical modernism. (en.wikipedia.org)

• Jetwing Lighthouse — Galle. One of Geoffrey Bawa’s later hotel projects, sited on a rocky promontory above the sea with interlinked open spaces and strong indoor–outdoor relationships. (en.wikipedia.org)

• Cinnamon Bentota Beach (formerly Bentota Beach Hotel) — Bentota. Designed by Geoffrey Bawa in the late 1960s; explicitly described as “tropical modernism” and one of the earliest resort expressions of that approach in Sri Lanka. (en.wikipedia.org)

• Blue Water Hotel — Wadduwa. Often cited as one of Bawa’s last hotel projects, combining minimalist modern lines with coastal tropical siting and materials. (en.wikipedia.org)

• Heritance Ahungalla — Ahungalla. Another coastal hotel designed by Geoffrey Bawa; notable for tropical-modernist composition and integration with sea views. (en.wikipedia.org)

• Anantara Kalutara Resort (formerly founded as a Bawa project) — Kalutara. Geoffrey Bawa began the design and his protégé Channa Daswatte later completed the resort; the property promotes its Geoffrey Bawa–inspired “tropical modernism.” (anantara.com)

• Amanwella — Tangalle. Designed by Kerry Hill, the resort explicitly references Geoffrey Bawa’s tropical-modernist legacy (minimal, pavilion‑based layouts, local materials, strong indoor–outdoor flow). (cntraveller.com)

• Kahanda Kanda — Koggala (near Galle). A boutique villa-hotel by Bruce Fell‑Smith (owner/designer George Cooper), with pavilion layouts, verandas and polished-cement floors that read as contemporary/tropical modern. (asiangeographical.com)

• Palm Hotel Sri Lanka — Ahangama. A recent boutique property described by designers and press as a contemporary, tropical‑modern take (mixing minimalist tropical design with industrial/brutalist touches). (hospitalitydesign.com)

• Jetwing Vil Uyana — Sigiriya. While often described as “eco-architecture,” its sensitive siting, simple forms and strong landscape integration make it relevant to travellers interested in modern, landscape-led tropical design. (en.wikipedia.org)

What to look for (characteristics of tropical modernist hotels)

• Strong indoor–outdoor connections: courtyards, verandas, sliding walls and cross‑ventilation.
• Use of local materials and craftsmanship: stone, timber, terrazzo, terracotta and carved elements.
• Long, horizontal compositions and pavilions that follow the landform rather than dominate it.
• Shaded circulation (pergolas, deep overhangs), water features and planted courtyards to cool spaces passively.

If you want, I can: (a) make a short list by region (south coast, southwest/Galle, Cultural Triangle), (b) map these properties, or (c) show a few images or architect bios for the designers mentioned.
