I noticed that you are a new mapper. Welcome to HOTOSM.
We cannot expect that you are already familiar with all issues around mapping. Therefore, I inform you about the most issues,

Please pay attention to next points:
Buildings are in general rather rectangular. Just 4, 6 or 8 nodes are sufficient.
Each building need to be squared.
Nodes of buildings may not connect to other buildings or features.
The shadow of a building is not a part of the building. 
Do not cluster buildings. Each building need to be mapped individually.

This kind of tasks are rather difficult. Even for an experienced mapper.
Please select a somewhat easier task to start with. ( On this project only dense urban tasks are still open for mapping. Select another project.)
