History
Hitachi Tower was designed by Murphy/Jahn, Inc. Architects, and local firm Architects 61 Pte Ltd. It was completed in 1992. Other firms involved in the development include Hitachi, CapitaLand Commercial Limited, Savu Investments Private Limited, CapitaLand Limited, Obayashi Gumi Corporation, Sendai Eversendai Engineering Group, Steen Consultants Private Limited, PCR Engineers Private Limited, and Rider Hunt Levett & Bailey.

Selling of stake
On January 16, 2008, CapitaLand sold its 50% stake in Hitachi Tower for S$403.5 million, which it had earlier bought in 2000. The National University of Singapore, which owns the remaining 50% of the office building, also sold its stake. Upon the deal's completion, CapitaLand will recognise a gain of S$110.1 million.

According to CapitaLand, the deal took into consideration the agreed value of the development at $811 million, or about $2,900 per square foot of net lettable area. It also claimed the consideration was arrived at on a willing-buyer willing-seller basis. However, the company did not state the buyer, but sources said that the building was bought by a fund linked to Goldman Sachs. This is based on the fact that Goldman Sachs bought the next-door Chevron House a year earlier.

In January 2011, NTUC Income acquired a 49 percent stake in Savu Investments, the holding company which owns the asset, from Goldman Sachs. In January 2013, NTUC Income bought over Goldman Sach's remaining 51% stake in Savu Investments, the acquisition valuing the property at around $660 million, or less than $2,400 per square foot, on a net lettable space of over 278,000 square feet.

Architecture
16 Collyer Quay is linked to the 33-storey Chevron House by a four-storey glass galleria. According to the Urban Redevelopment Authority (URA), the two buildings are designed and planned in parallel, with each tower takes on different architectural expressions, while complementing each other to "strengthen the urban quality" of Raffles Place.

The building is topped off by a two-storey navigating beacon. URA claims it recalls the maritime history of the Collyer Quay area. Its facade is expressed in three parts, which breaks the verticality of the 37-storey tower and creates a stepping down effect that matches with the height of its shorter neighbour, Tung Centre.

At the urban level, the two buildings respect and are designed around established patterns of pedestrian movement and urban use. The bank lobby is lifted to the upper floors to create Change Alley on the first storey, a pedestrian thoroughfare lined with retail activities that is today, a well-used and vibrant space linking Raffles Place to Collyer Quay.
