- It is 11.8 m wide at its narrowest and described as one of the world's slimmest skyscrapers, a "pencil tower"[3]
- Wikipedia gives 190 m and 57 floors (about 280 apartments), while Hickory gives 60 levels, 184 m and 259 apartments[2][3]
- Construction began in February 2016; Hickory reports a 29-month build with completion in September 2019[2][3]
- Hickory used conventional formwork to level 14 and then prefabricated structural units, cutting the programme by up to 30%; the tower incorporates a heritage facade and has a 4.5 m cantilever at level 14[2]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
