The south-eastern section of Calderwood Street is part of Bathway Quarter, a designated conservation area; the gurdwara and langar are not.

A chapel was built on Woolwich New Road, a site that is now occupied by the east end of Equitable House.

The new building would also house the Soldiers' Institute, the Methodist church being an official garrison chapel for nonconformists.

In 1977 the two buildings were put up for sale and shortly afterwards acquired by the local Sikh community to be converted into a gurdwara, which has been its function ever since.

On the south-west corner of the premises a tall, ornamented flagpole has been placed with a Nishan Sahib, the Sikh triangular flag.

On the parapet below the pediment a stone plaque with the inscription The Methodist Chapel, 1816 is now covered up by a wooden sign with the text ਗੁਰਦੁਆਰਾ ਸਾਹਿਬ ਵੂਲਿਚ - Gurdwara Sahib Woolwich.

Unusual in a Methodist church of this type is the presence of burial vaults underneath, "in case another Death should happen in the Preacher's family".

The main alterations for Sikh worship have been the removal of the pews and the insertion of a fixed floor where the galleries had been.

The main façade on Calderwood Street, now painted white, consists of three bays and three storeys (including the basement).

The building's main use currently is that of a langar hall (a communal refectory serving vegetarian food) with a kitchen.
