The sitcom centres around Phua Chu Kang (Gurmit Singh), an eccentric general contractor who wears yellow boots and is portrayed as an "Ah Beng", and his family, portrayed by Irene Ang, Pierre Png, Tan Kheng Hua, Marcus Ng Yi Loong, and Neo Swee Lin.

They decided to expand the Phua Chu Kang skit from Gurmit's World into its own show, particularly due to its popularity and that there was growing interest in stories about contractors.

[8][5]: 3:34  Before Phua Chu Kang Pte Ltd, Ang worked as an insurance agent and warmed up crowds before the show Under One Roof.

According to Eunice Tan, an executive producer for Phua Chu Kang, Chong left to continue a career in accountancy.

[5]: 11:53  Charlie Tan and Ray Kuan portray Phua Chu Kang's workers King Kong and Ah Goon, respectively.

His personal clothing trademarks are his yellow pair of boots (bought in Beach Road), curly hair, a giant black mole, and long nails on his pinky fingers.

Phua Chu Kang is portrayed as an "Ah Beng", which is a Singlish slang for a stereotypical, uneducated Chinese gangster, complete with habits such as hoisting one leg up on the seat of a chair when he sits down and growing one long fingernail to scratch his ears.

Even his company and office being PCK Pte Ltd is also located at the backyard of his bungalow house either, in which he hired 2 lazy workers who are the fat King Kong (Charlie Tan) who loves "tau huay" (a Chinese bean curd dessert) and the attractive yet slow-witted Ah Goon (Ray Kuan) who dresses in revealing denim cut-offs all the time.

Critics of the show labelled Phua Chu Kang as an inaccurate or perceived undesirable representation of Singapore, and denounced his appearance in The Amazing Race.

In 1999, the second Prime Minister of Singapore, Goh Chok Tong, referenced Phua Chu Kang during a speech at the National Day Rally.

In response, the sitcom's 3rd season opened with Phua Chu Kang earning a certificate for completing the "BEST English" course from Institute of Technical Education, and dialogue had to be adapted to limit the usage of Singlish.

[13] Phua Chu Kang Pte Ltd won "Best Comedy Programme" at the Asian Television Awards for six consecutive years from 1998 to 2003.

Apparently,[citation needed] the original idea was to have PCK at the pit stop alongside Phil Keoghan (at the end of every stage of The Amazing Race, there would be a local person dressed in traditional clothing welcoming the contestants to the country), but Singaporeans protested that this would give foreigners the wrong impression of the local people in general.

He, along with his younger brother Anthony Phua Chu Beng, made their first advertisement appearance regarding the introduction of 3G mobile services and phones in Malaysia by Maxis.

In 2022, the cast reunited after 15 years on an episode on CNA's On The Red Dot series, titled "Phua Chu Kang Reunion: How's Singapore's Favourite Contractor?".
