These houses were slated to be demolished after WW2 so over the years, public and private funds were raised to cover the costs to purchase, relocate and restore these historic buildings with their interesting stories.  Each home, named after the original family who built the home, has some history written about them on a display board in front.  
These houses have been completed on the outside and the gardens are lovely, too. The windows were all covered in paper as the restoration has not been done on the inside but one day they will all be available for Inn’s and Bed and Breakfast, following through with the historical theme. 
One house has been fully renovated and now operates as the Coral Tree Tea House, so named after the beautiful coral tree that sits in the center of the street out front.  It was busy with a private party while we were there so we didn’t go inside but I took plenty of photos of the coral tree that kept me busy.   
The coral tree is a Erythrina x sykesll Australia 
I started to notice more coral trees as we drove around the city after this and saw several; none of them had a lot of leaves but they did vary on that.  I am thankful that our timing was great to see those blooms.
