We used black butt for our solid timber flooring. The thing I really like about our floor is there is no quad around the walls. It was a very long process getting the flooring done, but well worth it. We were without flooring for about 4 months after moving in (we didn't get the builder to do the flooring, they don't do solid timber only floating floors). We needed to have the skirting fitted and then both the skirting and walls painted/touched up.
The lawn was laid in April last year and I think it look great.
A couple days of rain and its so green, the only regret is not installing sprinklers before laying the grass. Kikuyu Kenda Turf is a great lawn, we were told by the supplier that once it gets established it has low water requirements, but over summer we noticed that sections of the lawn dying. Installing the sprinkles would of made the maintenance easier. Over Summer it needed to be mowed every week, it is a very quick growing grass.
