Waymouth Street forms the southern boundary of Light Square, an open grassy park in the centre of the north-west quadrant of the city centre. This section of Waymouth Street is one-way traffic to the west; east-bound traffic must detour around the square. Traffic signals control the intersection with Morphett Street where it divides to go around the square. A few bars, nightclubs and restaurants are located on the southern side of Waymouth Street and around Light Square.
The section from Light Square to West Terrace has lower scale retail and residential buildings, including several hotels, hostels, car and furniture dealerships. Across from the intersection with West Terrace is a service road for Adelaide High School and an entrance point to shared pedestrian and bicycle tracks in the western parklands.
On 2 March 1994, a bomb exploded in the National Crime Authority offices in a building on Waymouth Street, after being sent to NCA Senior Investigator Detective Sergeant Geoffrey Bowen, killing him and severely injuring lawyer Peter Wallis. The initial suspect, Domenic Perre, who was released for lack of evidence shortly after being arrested, was re-arrested in 2018. Perre was standing on top of a nearby carpark and was later arrested at his house.[7][8] He entered a plea (of not guilty) for the first time in the Adelaide Magistrates Court on 17 February 2020 but his lawyer conceded that there is a case to answer and he was committed to stand trial in the Supreme Court of South Australia.[9]
Woodards House, originally an office building designed by prominent architect F. Kenneth Milne (then in practice as F. Kenneth Milne, Evans & Russell) for Norwich Union Fire Insurance Society, which included ground floor offices for the Commercial Bank of Australia.[11][12] The building contractor was prominent local builder Frederick Fricker, who died suddenly while on holiday, in Port Said, before the building was completed.[13][14][15] The building was officially opened on 5 June 1929, after a dinner the previous night attended by many local dignitaries.[16] The building was state heritage-listed on 23 August 2013, and described as "an outstanding example of a building constructed in the Inter-War Commercial Palazzo style". An additional floor was added in 1953.[17]

Retrieved 22 April 2024. originally licensed as the Crown and Anchor Hotel on a site further along Elizabeth Street, the current Cumberland Arms Hotel building dates from 1883 and was designed by H C Richardson for Sir E T Smith, brewer and philanthropist. It is a typical corner hotel with chamfered corner and verandah/balcony, but features some ebullient detailing which makes it out of the ordinary. It also serves as a reminder of the once dense residential development in the west end of Adelaide. The interior is significant for its fine entrance hall and staircase and for its upstairs rooms being largely intact.
