text: It would make the disused Fawley power station chimney the tallest such attraction south of London's Shard.
  Developers Fawley Waterside said it would be the centrepiece of a "merchant city" development.
  The power station closed in 2013 after more than 40 years in operation.
  Architects plans show a petal-shaped glass structure at the centre of a Â£1bn development featuring a marina, housing and restaurants.
  It also includes fast ferry links to Southampton and Portsmouth.
  With an application for outline planning permission due later this year, building could start in 2018.
  The oil-fired Fawley Power Station, on the western side of Southampton Water, was commissioned in 1971 and was capable of powering one million homes.
  The 300-acre site was sold to Fawley Waterside developers in 2016.
  Aldred Drummond of the company said: "We'd be mad to knock the chimney down - its our signature piece of infrastructure.
  "If you think of the money spent building the i360 in Brighton, or the Spinnaker Tower in Portsmouth, this building is already there so with relatively little investment we can do something very spectacular."
