The Calyx, a new landmark for Sydney

PTW Architects in collaboration with landscape architects McGregor Coxall and Cockram Constructions is proud to be involved in the design and delivery of this project. The PTW team involved in bringing The Calyx to life included Troy Uleman, Neil Hill, Glen Harper, Rod Brown, John Shipp, Sara Best and Rebecca Quin. The Calyx (pron. kal-iks, def. ‘The outermost whorl of flowers’), a leading horticultural display, research and education centre for the Royal Botanic Garden Sydney formed the special centerpiece of the Garden’s 200th birthday initiatives last month. Coined ‘a jewel in the Garden’ for its elevated position and sense of arrival, The Calyx is envisioned as an iconic but serene addition to the Gardens as a whole. The key element of the building is the new ‘Iris’. This circular steel structure is the most highly visible part of the building from afar and contains the foyer, education and retail space that can be turned into event spaces at night with retractable walls that allow the exhibition and event space to be combined. Won by a Design Competition, PTW worked with Cockram Construction and McGregor Coxall to design this highly flexible building that will showcase ever-changing exhibitions. The team used the existing elements of the Arc, originally designed and constructed in 1994 by renowned Australian Architect, Ken Woolley, whilst retaining the extraordinary design quality, integrity and innovation of the existing structure.

Pacific Bondi Beach shortlisted for the 2016 Sydney Design Awards

We are delighted to announce that Pacific Bondi Beach has been shortlisted for the Sydney Design Awards in the Mixed Use category. An iconic addition to the Bondi beachfront, the adaptive re-use project transformed the structure of the former Swiss Grand Hotel, with new facades and additional floors. The mixed-use development includes 110 luxury apartments, a 69-room QT hotel, a Woolworths Metro and BWS store, a Gold’s Gym and Speedos pool facility, retail including cafes, restaurants and fashion boutiques as well as public car spaces. The successful integration of retail, hotel and residential is not commonly done in Sydney. Pacific Bondi Beach can also boast an Australian-first in residential apartments through the unique curved zinc vault roofs with the electronically operable gull-wing doors, designed and manufactured in Sydney.

The Miller, the story is in the details

PTW is responsible for the architecture and interior design for The Miller in North Sydney, Yuhu Group’s first residential project in Australia. With strong market uptake, the stage one release of apartments in March was a sell-out. Scheduled for completion in 2018, the development at 221 Miller Street consists of 183 residential apartments, 100 serviced apartments and ground floor commercial space for a café and restaurant. Our vision for the building was to express the three different components with folds of architectural origami articulated with a differing geometric solution. The residential levels, towards the top of the building become softer and warmer and the detailing finer, incorporating well-crafted golden perforated facade panels. This configuration complements the stronger portal geometry of the five levels of serviced apartments. A stand-out on Miller Street, the architecture reaffirms the existing leafy landscape characteristic of the public domain; while regenerating the area with a modern design consistent with the future plans of the area.

Movenpick Hotels and Resorts

The Ho Chi Minh Office have been busy with this stunning 40,000sqm resort hotel. Commissioned to provide full architectural design services, the overall curvilinear form of the hotel and its swimming pools are inspired by the fluidity of water and Vietnam’s colourful curvilinear rice terraces in the nearby Southern Highlands. Due for completion in 2017, the hotel forms part of a greater 42 hectare hospitality development in Cam Ranh Bay in South-Central Vietnam. The 250-key hotel features a host of facilities including a convention centre, a sizeable sports centre, team building park, spa, a Swiss-themed village, as well as 124 terraced timeshare villas comprising one, two and three bedroom units. On top of the extensive facilities on offer, all guest rooms in this 4-star hotel will have expansive ocean views, which are accessed via naturally ventilated open passageways featuring unobstructed views across the mountainous backdrop.

Nanjing Huaneng – our Shanghai office’s latest

Due for completion in 2019, this waterfront mixed-use project consists of two 150m office towers, one five-star hotel, one high-end serviced apartment building, a shopping centre, residential buildings and a landscaped boulevard culminating in a river view platform. This landmark project designed for China Huaneng Group is more than 500,000sqm and once complete, will be one of the most important developments along the Yangtze River in Nanjing. PTW are involved in the masterplan and design of the two Z-type buildings outlined in red on the image along the central axis, one being the serviced apartment building and the other the five-star hotel on the right side. Our design concept was to lower the first row of buildings from the Yangtze River to maximise the water views of the twin towers behind, thus bringing up the breeze and opening up the waterfront. The landscaped boulevard connects all the elements together, leading people from the subway to the various buildings and to the river view platform at the end of the spine.

Indigenous Summer School Programme

Indigenous Programme
Angus Stevens and Mona Chao from our Sydney office were fortunate enough to be involved with the Indigenous Summer School Programme at the University of Sydney. This programme encourages year 11 and 12 Aboriginal and Torres Strait Islander students to pursue a career in architecture by way of a design exercise. The students learned some of the basic skills needed to draw plans and sections before embarking a model of their design.
