the Museum of New Zealand Te Papa Tongarewa lies on the waterfront, on Cable Street. It is strengthened using base isolation – essentially seating the entire building on supports made from lead, steel and rubber that slow down the effect of an earthquake. Other notable buildings include Wellington Town Hall, Wellington railway station, Dominion Museum (now Massey University), Aon Centre (Wellington), Wellington Regional Stadium, and Wellington Airport at Rongotai. Leading architects include Frederick Thatcher, Frederick de Jersey Clere, W. Gray Young, Bill Alington, Ian Athfield, Roger Walker.Wellington contains many iconic sculptures and structures, such as the Bucket Fountain in Cuba Street and Invisible City by Anton Parsons on Lambton Quay. Kinetic sculptures have been commissioned, such as the Zephyrometer. This 26-metre orange spike built for movement by artist Phil Price has been described as "tall, soaring and elegantly simple", which "reflects the swaying of the yacht masts in the Evans Bay Marina behind it" and "moves like the needle on the dial of a nautical instrument, measuring the speed of the sea or wind or vessel." Wellington has many different architectural styles, such as classic Painted Ladies in Mount Victoria, Newtown and Oriental Bay, Wooden Art Deco houses spread throughout (especially further north in the Hutt Valley), the classic masonry buildings in Cuba Street, state houses particularly in the Hutt and Wellington's southern suburbs, railway houses in Ngaio and other railway-side suburbs, large modern buildings in the city centre (such as the distinctive skyscraper called the Majestic Centre) and grand Victorian buildings common in the inner city as well. Housing and real estate House prices Historic Wellington experienced a real estate boom in the early 2000s and the effects of the international property bust at the start of 2007. In 2005, the market was described as "robust". By 2008, property values had declined by about 9.3% over a 12-month period, according to one estimate. More expensive properties declined more steeply, sometimes by as much as 20%. "From 2004 to early 2007, rental yields were eroded and positive cash flow property investments disappeared as house values climbed faster than rents. Then that trend reversed and yields slowly began improving," according to two The New Zealand Herald reporters writing in May 2009. In the middle of 2009 house prices had dropped, interest rates were low, and buy-to-let property investment was again looking attractive, particularly in the Lambton precinct, according to these two
