This is an interesting tiny cottage and I love the Frangipani in the front garden. So if I go my hands on it, I would do the following. (Sold $710k)
The front would change only by painting the front windows blue and the door yellow like below.
Then following the floor plan above the living room would change from the below
As there are no other photos for the house, I would then change the rooms as follows:
The bedroom would look good like this.
The dining room and kitchen would look like this.
Then I would put in a bathroom like this.
Then I would change the backyard to this with the garage door.
