I need help creating view models for the following scenario:

1. Deep, hierarchical data
2. Multiple views for the same set of data
3. Each view is a single, dynamically-changing view, based on the active selection
4. Depending on the value of a property, display different types of tabs in a tab control

My questions:

Should I create a view-model representation for each view (VM1, VM2, etc)?

1. Yes:
    a. Should I model the entire hierarchical relationship? (ie, SubVM1, HouseVM1, RoomVM1)
    b. How do I keep all hierarchies in sync? (e.g, adding/removing nodes)

2. No:
    a. Do I use a huge, single view model that caters for all views?

Here's an example of a single view

Figure 1: Multiple views updated based on active room. Notice Tab control

Figure 2: Different active room. Multiple views updated. Tab control items changed based on object's property.

Figure 3: Different selection type. Entire view changes
