A Dutch architectural firm is expressing regret over a design for towers in South Korea that evoke an image of the burning World Trade Center.

The rendition of the buildings appears on the website for the firm, MVRDV.

The luxury apartment towers are connected by what is described as a “pixelated cloud.”

In a statement on the website, the firm apologized by saying, “It was not our intention to create an image resembling the attacks nor did we see the resemblance during the design process. We sincerely apologize to anyone whose feelings we have hurt, it was not our intention.”

The firm says it has no plan to change the design.

Each tower is expected to be more than 850-feet tall.

It’s slated to open in 2015.
