66 families + a house for Kann in Ahuzat Bayit

Yechiel Yechieli, who was one of the 66 families of Ahuzat Bayit, gets a contract to build a house for Jacobus Kann in the first neighborhood of Tel Aviv.

I found this document in the Tel Aviv Archives, it is dated to September 10 1909 when the first houses were under construction.

Where is/was this house of JHK located?
