Hi there, I think I can help! 82a/84a were built in 1896, the surrounding houses in 1894. There was a road that ran between 82 and 84 which was a continuation of what is today Chesterfield grove. This was closed with the building of Glengary road and the neighboring Trossacs & Tarbert Rd behind Melbourne Grove...the space was filled in with two new houses. They are very similar to the houses either side with the exception of neither having had a cellar built which is unusual for 4 bedroom Victorian houses of this type.
