Hello,
If hou are planning to take a loan against that property then you will have to get the same transferred in your name which can be done through a sale deed If the property is the self acquired property by your father.
And if you just want to start the construction on that property then you can start the same, this will not make any difference as to who holds the title of the property.
And if you anticipate that your sister might fight for the property in future it is better to get a will registered.
Regards
Let me know if you need further clarification
