As a result, by 1998 Woodside had its Perth staff spread across six sites,[7] including Central Park and the headquarters at 1 Adelaide Terrace.

Perron Group put forward a proposal to leave Woodside in its existing headquarters on Adelaide Terrace and build a tower beside it to house the other staff.

[8] This proposal was to develop Hai Sun Hup's site at the corner of St Georges Terrace and Milligan Street into an office tower and hotel project.

[11] The development also necessitated the demolition of the building on Hay Street which housed the Matsuri Japanese Restaurant, which moved to new premises in QV.1.

[4] Under this deal, Deutsche Asset Management paid Hai Sun Hup $23 million for the building site and development contract, and Woodside agreed to lease 32,500 square metres (350,000 sq ft) of the tower for 15 years, with two five-year options to extend.

[18] Although the building would add 46,000 square metres (500,000 sq ft) of office space to the central business district[19] and raise the premium-grade office floor space in the central business district by 24 per cent, Woodside was to occupy so much of it that only 13,500 square metres (145,000 sq ft) would be available to other tenants.

[21] This was reduced to less than two floors unleased in April 2004 when accounting firm Deloitte Touche Tohmatsu signed on as tenant, vacating its office in Central Park.

[4] It was thought that the move of Woodside to the western end of the central business district would draw other resources companies to the area.

[20] The plans originally included the construction of a hotel adjacent to the new office tower on the Hay Street side of the site.

[30] It features 251 basement car parking bays, a bar on the ground floor, shops, a 120-seat auditorium on the mezzanine level[1] and a fully equipped gym.
