Projects Completed by Fadi Jirjees
The Christchurch Hotel
The Christchurch Hotel rising proudly on Colombo Street in the very heart of Christchurch, this boutique hotel marries genuine South-Island hospitality with an unrivalled location, only a few steps from Cathedral Square, Te Pae Convention Centre, and the historic tram stop.
Its 44 light-filled studios and two executive suites surround guests with modern furnishings, smart-streaming TVs, high-speed Wi-Fi, and whisper-quiet climate control for effortless comfort.
All of the above is underpinned by an advanced fire-engineering strategy and a superior automatic sprinkler system that not only secured the building’s consent but also enhances protection for the neighbouring property, giving guests peace of mind alongside every indulgence.
Christchurch Casino
Envisioned in 1992 and unveiled in November 1994 as New Zealand’s very first licensed casino, Christchurch Casino quickly became the Garden City’s entertainment anchor.
Today, its 4000 sqm gaming floor boasts 32 gaming tables, more than 450slot machines, and three distinctive restaurants and bars. The property’s resiliance was tested by the 6.3-magnitude Canterbury earthquake 2011. After structural checks and targeted repairs, the casino reopened to publics in less than 12 months later, restoring a welcome slice of normality to Christchurch CBD.
The BNZ Centre
BNZ Centre is the flagship of Christchurch’s post-quake retail and office precinct. Two steel-and-glass buildings (30,000 m² in total) wrap around a sun-drenched courtyard, all linked by a network of pedestrian laneways and covered arcades that stitch Cashel Mall to Hereford Street and the wider CBD.
At street level, 37 boutique retail and hospitality tenancies create an always-open urban marketplace, while a naturally ventilated car park floats above, freeing the ground plane entirely for people. Large 3,000 m² office floorplates on the upper levels—anchored by Bank of New Zealand—deliver flexible workplaces bathed in daylight and framed by balconies overlooking the courtyard below.
Burwood Hospital
Burwood Hospital is a state-of-the-art, 230-bed campus in north-east Christchurch that opened in 2016 as part of the country’s largest health-building programme.
Spanning roughly 29,000 m², the facility is New Zealand’s specialist hub for older-persons’ health, spinal-cord and brain-injury rehabilitation, and elective orthopaedic surgery.
Purpose-designed to IL3 seismic standards, it houses a dedicated spinal unit, stroke and adult rehabilitation wards, light-filled single patient rooms, a 1,100 m² radiology department equipped for MRI and CT, and an outpatient centre capable of handling up to 80,000 visits a year
Ariwhenua Hydro Station
Tucked into Bay of Plenty’s lush Galatea Valley, Aniwhenua Hydro Station harnesses the natural drop of the Rangitāiki River just above the picturesque Aniwhenua Falls.
Commissioned in 1982, the run-of-river scheme channels up to 75,000 litres of water every second through two high-efficiency Francis turbines, delivering 25 MW of installed capacity and about 127 GWh of renewable electricity each year, enough to supply roughly 15,000 New Zealand homes.
