ONCE Wongamat

Inspired by North Pattaya’s azure waters, ONCE Wongamat’s design seamlessly integrates beauty with ecological mindfulness. The facade not only captivates but also provides shade, ensuring cooler interiors. Reflecting the sky's shifting hues, the building embraces nature with green terraces and open spaces. This thoughtful design creates a rareness connection between urban living and coastal serenity. (https://oncewongamatpattaya.com/)

Following the groundbreaking ceremony on 27 June 2025, our Managing Director, Somchai Apipattanavis, participated in a discussion panel alongside Dr. Kanokpat of Bouygues-Thai Ltd. and other key project members. The panel focused on the key design aspects of this landmark project, covering topics such as wind tunnel testing, seismic design considerations, the use of advanced analysis and design tools, and the construction of pile foundations on rock. While seismic design is not required by the regulations, the project owner, HONOUR Group, has clearly directed the team to incorporate ductile seismic design measures into the building structures to ensure the highest level of safety for future occupants.

InGen Design, in collaboration with Design 103 International Limited, is proud to provide structural engineering design services to Bouygues-Thai Ltd., the Design-Built main contractor of the project.
