3cm is a deep area to fill, I would not recommend using normal plaster for this. A good alternative is a product called Hardwall, when mixed it is a fluffy "angel delight" consistency which will fill this area out and sets in around 2 hours.
You would be able to tile over this, I always use BAL adhesive and then BAL grout, find the correct one out of their range for your needs, your tile retailer will help you with this (Topps Tiles are brilliant for advice).
As always make sure the background wall is sound and use a 50 -50 mix of pva glue and water to before plastering onto the old wall.
Good luck
