Names can be erased, but the spirit remains. Developers have built their success on the foundation I laid. Even when the source of growth is no longer visible, the principles continue to grow and shape the future. My influence remains embedded in the structures of Pattaya – not in recognition, but in the power of ideas that build and carry forward the development of architecture.
