Before starting a large-scale renovation, it would be a good idea to decide what you actually want to see.
Perhaps it will be enough to re-glue the wallpaper and repaint the ceiling. But if you are planning global changes, then haste may be the wrong decision. Here is a reliable scheme.
The most difficult and responsible thing before a grand renovation is to imagine a picture that should coincide with reality. This is the starting point for the main work. It is better to foresee all ideas before the start of the renovation, otherwise at the main stage it may turn out that some of the work cannot be implemented.
From sketches and drawings, you need to switch to planning, especially if you need to divide the room into zones. Perhaps it will be enough to rearrange the furniture and the room will become fresher and more comfortable.
You need to plan your furniture purchase. It is advisable to have a clear idea of what and where you want to see, and in what color scheme, before starting the renovation.
Communications are the most important thing. Some issues may require the intervention of specialists. For example, in the bathroom, you will need the help of a plumber, as well as an electrician or gas workers.
When faced with these issues during renovation, you can waste a lot of time and spend extra money if you do not plan certain work in advance.
