The Sentinel (sometimes The Sentinel or Sentinel Tower) is a luxury residential skyscraper in Takapuna, the central business area of North Shore City, New Zealand. The largest and currently only real skyscraper in the city, it has 30 levels and is 150 m tall including spire. It offers sweeping views over the Waitemata Harbour, the wider Hauraki Gulf as well as over to the Auckland CBD skyline. The Sentinel was opened to the first residents in February 2008. The building contains 117 luxury apartments, with the uppermost two levels forming a massive 675 m² penthouse, which has recently (2007) sold for NZ$ 11 million. A communal area on level four includes a 25 m x 6 m heated swimming pool and spa, sauna and gym facilities as well as landscaped areas.
The building contains a number of motifs, from the square (used extensively in the glass facade proportions and in smaller details), to a woven flax basket (hinted at in the latticework of the facade) to the spire atop the building which evokes a sail, especially from further away across the Hauraki Gulf.
