Small house borders large empty lot and some greenery. How did this post-war house survive, and how long has the neighboring lot stood empty?

この小さな戦後に建てられた家は、東京の終わらない再開発を生き残りました。手前の大きな空き地が、どのくらい空いていたのだろうと思います。

This small post-war house has survived Tokyo’s constant re-development. I wonder how long the large empty lot in the foreground has stood empty.
