The ground floor consists of a langar (dining hall), a kitchen, an office and a library, visitors' rooms and classrooms for holding Punjabi classes.
Many Sikhs were employed by the Federated Malay States Police to maintain law and order.
Gradually, more Sikhs arrived in Klang and became watchmen, money lenders, dairy farmers, bullock cart operators and chauffeurs.
By 1930, there were about 200 Sikhs living in and around Klang and the Gurdwara Sahib was inadequate to accommodate the ever-growing sangat.
Between 1933 and 1934, a double storey wooden building with a tiled roof was built on the site of the original Gurdwara Sahib.
In August 1989, the Government offered the Sikh community of Klang a new site about an acre in size, Lot Number 970, which is the location of the present Gurdwara Sahib.
