The main entrance doors were panelled with hammered pewter – a white alloy that resembles tin. The company's name was executed in hammered pewter, another example of the architect using tin as a motif for the company. Dadoes for the staircase and entrance vestibule were made of a new material, Marbrunite, in multiple colours. A motor car garage was incorporated into the ground floor. The Anglo-Oriental building has solid tower-like features flanking the corner entranceways in addition to vertical and horizontal Art Deco patterns and lines. The vertically banded front elevation of the building, which is held between two towers, contrasts with the horizontal bands of the two side wings. The tall, first floor windows of the Anglo-Oriental Building have individual concrete canopies, while the second floor is treated as a narrow band which appears to recede due to the deep, continuous overhang above the windows and the darker shade of Shanghai plaster. An internal open courtyard was roofed over for air-conditioning in the 1960s. During the 1941 Japanese invasion, the building was used as a police station. From 1986 to 1988, the architect Chen Voon Fee renovated the Anglo-Oriental Building and it was converted into Mahkota College, a private college partnered with Boston University. From 1995 to 2005, the Anglo-Oriental Building became a property of Ekran Berhad and it served as the corporate headquarters until 1 January 2005, where the second floor housed the principal place of business of the company. It was then that the present name – Wisma Ekran (House of Ekran) was established. Although Art Deco is seen generally in individual urban buildings, in the Rubber Research Institute Building it is employed for a complex of linked, single-storey buildings set in a landscaped compound. The buildings are almost modular with identical facade elements. Unlike most other examples, these buildings are in facing brick, with monumental corner piers. These piers frame the window openings, which are divided into three vertical bands by two large, protruding plaster mullions. Three horizontal rendered beams appear to be threaded through these mullions, visually tying the piers together. On the flat, recessed brick pediment, a plaster motif of layered latex sheets hanging out to dry is a witty allusion to the industry these buildings serve. The buildings are grouped around green courtyards and linked by covered masonry walkways. The walkways have amusing spout details over the beams which throw the rainwater from flat roofs.
