TR紅磚之TR二字是「臺灣煉瓦（Taiwan Renga）株式會社」的英文縮寫，煉瓦是日文的漢字，中文翻譯為「紅磚」。1913年日本人後宮信太郎於臺灣臺北成立臺灣煉瓦株式會社，製程方式以一款乾式壓磚機所壓製，紅磚燒製後密度高重量十足，為當時有品質保證的一等建材，當時多用於公家機構的各種建物上。在民宅建築上，有些人會刻意將有壓印TR的磚面砌於建築物外側，以象徵個人或家族財力豐厚。

TR紅磚雖然已經停止生產多年，但仍然可以在許多舊式建築中發現，藉由3D建模的方式，讓更多人認識這塊擁有百年歷史紅磚的故事。

The "TR" in "TR Red Bricks" stands for "Taiwan Renga Kabushiki Kaisha" in English, with "renga" being the Japanese kanji for "brick," translated into Chinese as "red brick." In 1913, Japanese entrepreneur Uemon Shitatarō established the Taiwan Renga Kabushiki Kaisha in Taipei, Taiwan. The company utilized a dry-press brick-making process, resulting in dense and heavy red bricks that were considered top-quality building materials at the time. These bricks were commonly used in various government buildings and occasionally in private residences, where some individuals deliberately showcased bricks imprinted with the "TR" mark on the exterior to symbolize wealth or family status.

Although production of TR red bricks ceased many years ago, they can still be found in many old-style buildings. Through 3D modeling, the story of these century-old red bricks is being shared with a wider audience.
