The architecture of Laganvale Street is remarkable for its terraced flat-roof houses, a style usually associated with seaside resorts. Some of the houses are rendered, while others display the brickwork.
The name refers not just to valley of the River Lagan, which is close by, but to this specific estate in Stranmillis. Lagan Vale Estate Brick & Terra-Cotta Works Ltd was established here in 1909, but there are references to Lagan Vale Brick Works in newspapers as early as 1897. Also Lagan Vale was an earlier name for Lockview Road.
"That on the application of the owners a new street on property situate Off Lockview Road be named Laganvale Street and a new street on property situate off Ridgeway Street be named Strandview Street." Town Improvement Committee, 20th June 1900.
The dual language street signage was approved in June 2024.
