There are a number of different posts from this site, so I thought I should do a quick overview of the house to give the context to avoid having to repeat it each time. Other posts from this site can be found under the tag.
Runnymede is in National Trust property, in New Town, a suburb of Hobart. It was built in the 1830s and has been added to over the years. That room on the right is one such addition.
If I remember correctly, it is the ballroom, and has a side entrance via a bay window (partly hidden here by the tree).
The front section of the house is sandstone, but most of the it is painted brick
At the rear of the house. The next three photos are of this area, going clockwise.
