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.

Busy Sunday in Lower Fort Street

Woken at 4am by hammering on the Bridge - dozens of workers and lots of machinery doing essential track maintenance the only time it can be done, so this is OK.

The bridge paint sucker underneath was also going flat out, making a high-pitched noise just short of painful. Unusual this is going on a Sunday.

Didn't seem to diminish the number of people walking through Tarra Park, then weaving along Parbury Lane beside the house 'Tarra', or down the beside the other half of the pair, 'Mascotte', then along the alleyways and other walks that weave through Millers Point.

Visitors might have noticed that the 1980s pyramid atop the Park Hyatt lift shaft has come off. There is something afoot here. Are they starting on their rooftop extension already? Is this a fight lost before we have even begun to respond?
