Software to keep track of renovation
Take a look at Trello. I use it set up as a Kan-Ban board (think of loads of post-it notes in columns for "to do", "doing" and "done").

You can also add your own columns (so you could have a "suppliers" column for example).

You can add images and ideas, as with Pinterest, and assign dates to cards to in order to track them. 

There are various plugins available too, so if you wanted to view the project as a Gantt chart, for example, you could do this too.
