This renovation project began after winning a competitive pitch against two other companies.

Through the initial site survey, we found that the headquarters is located outside the metropolis in a town with greenery and riverside views, so the goal was to make the office feel more suburban.

Thai Petroleum Pipeline transports refined petroleum products from downstream to storage, where trucks then come to pick up the petroleum. Thus, the company resembles the root that sends up water to the tree. Based on this concept, vertical lines were used throughout the design to imply the growth of the company with the benefit of existing building features like high ceilings, double-height spaces and skylights. Natural light and natural color schemes like sunrise, sunset, and oceans, were also used throughout the space.

The main element of the interior design concept was the conduit, which represents the pipeline and vertical linkage for the perspective from the lobby to the double space. This vertical line was also used the same design language for the whole space - frosted film

Space in the building was initially divided according to room type (lobby, office, meeting room, etc.), but the new layout plan converted these enclosed spaces into an open space. As a rapidly growing company, this open space layout could also be beneficial in the future when hiring more staff. Double height was also added at the foyer and a connection was made from the lobby to the staircase.

The layout plan was also tailor-made for workstations. The hallway doubled as a storage space that connected to the workstations, so even though it is an open office the space still looks clean and sleek with enough storage for files.

Interlocking and open spaces were created to manage privacy across public and private spaces. To compensate for the loss of private rooms and enclosed spaces through this new layout plan, a lounge with glass bookshelves and a self-service pantry was created for more casual meetings.

The building façade was also redesigned and interior zoning was rearranged.
