In one of the first 2021 sales, Stamford Hotels and Resorts has sold Stamford Green at 899 - 927 Hay Street, Perth for $67.8 million, after having rejected an offer of $134 million ten years ago. Stamford Hotels and Resorts was formed in 1995 by parent company, Stamford Land Corporation Limited (formerly known as Hai Sun Hup Group Ltd), one of Singapore's best known public companies. 

Stamford Green is comprised of a 14-level office building and three existing heritage buildings, refurbished and rebranded in 2020 (formerly Dynons Plaza). The office tower, completed in 2010, is an A-grade building comprised of 12 office floors, ground floor retail space and basement car parking. The building has a net lettable area of 13,360 sqm and typical floor plates of around 1,070 sqm.

The three heritage buildings include China Hall, a 373 sqm building which retains the facade of the original Dynon's Buildings; Plaza West, a two-storey, 829 sqm building and the 427 sqm Bank of NSW Chambers building. Hugo Boss and Tony Roma's Ribs, Seafood & Steaks are among the current tenants, but the office building remains empty after Chevron did not renew its lease in 2020 and vacated the building.

The purchaser of Stamford Green was Redhill Partners, a Singapore based private investment company controlled by founder, James Hyndes and Senior Partner, Oliver Mahe, both of Singapore, plus Christopher Zielinski of Perth. The company is owned by Redhill Holdings Ltd and 181 Investment Group Ltd, both of the British Virgin Islands.
