Cate Blanchett is greening the Wharf Theatre with the roof to be covered with hundreds of solar panels plus lots of smart things inside.

Today's entertainment has been the building of rooftop staircases ready to carry the panels, seen here through the ripples of old glass in our much-loved dining room doors.

This is a great development and one we are happy to support at the rear of our home, but there is another planned just in front -- the Park Hyatt wants to add a 5.9-metre-high floor to their roof for four penthouse suites plus rooftop swimming pools and raised terraces. I don't think our neighbourhood needs another party venue like the Ivy, and Ken Woolley would be sad to see what they have planned for his beautiful building designed to sit below the parapet of Dawes Point Park so this historic park and the houses built in the 1830s could retain their link with Sydney Harbour and their long maritime history.

If the bulbous addition to the Park Hyatt goes ahead, the elegant serpentine Park Hyatt will become the elephant in the harbour.
