The PTT LNG is a company dedicated to providing world-class natural gas receiving and distribution services. With a vision to promote clean energy and enhance energy security in the country, the concept of the PTT LNG headquarters aims to create a transparent business environment, a pleasant working space for employees, and accessibility for all external visitors. The design incorporates unique features such as a Tulip Garden and the Cold Climate Flora Garden within the building. The creation of these gardens is possible by harnessing the cold energy which is byproduct generated during the conversion from the gas’s liquid state to its gaseous state. This transformation of LNG's energy value into tangible elements not only improves the working atmosphere beyond conventional office spaces but also allows the general public to visit and appreciate the gardens as educational spaces for botany and energy sources like LNG. The open-plan workspace design helps reduce daily work stress, while the open free-form roof structure seamlessly connects with the adjacent open space to provide a clear view of the transparent working environment from the gardens. This design vision fosters a sense of unity, trust, and credibility among the company’s employees and image, its products, and the LNG industry as a whole.
