Angular2 - Project Structure

Question

I will start to a new Angular2 project and I am trying to understand the best structure for an Angular2 application. Let I have pages as home, auto-galleries, nearest-galleries, brands, cars and selected-car. And the navigation order is

home -> auto-galleries -> nearest-galleries

or

home -> brands -> cars -> selected-car

For the best approach, should I use components or modules for each page? If modules are a better approach, should I use hierarchical modules or all at same level under the root module?

For example, how good is the structure below:

app
├--- app.module.ts
├--- app.component.ts
├--- home.html
├--- brands
|    ├--- brands.module.ts
|    ├--- brands.component.ts
|    ├--- brands.html
|    ├--- cars
|         ├--- cars.module.ts
|         ├--- cars.component.ts
|         ├--- cars.html
|         ├--- selected-car
|              ├--- selected-car.module.ts
|              ├--- selected-car.component.ts
|              ├--- selected-car.html
|
├--- auto-galleries
     ├--- auto-galleries.module.ts
     ├--- auto-galleries.component.ts
     ├--- auto-galleries.html
     ├--- nearest-galleries
          ├--- nearest-galleries.module.ts
          ├--- nearest-galleries.component.ts
          ├--- nearest-galleries.html

Or is this structure better:

app
├--- app.module.ts
├--- app.component.ts
├--- home.html
├--- brands
|    ├--- brands.module.ts
|    ├--- brands.component.ts
|    ├--- brands.html
|
├--- cars
|    ├--- cars.module.ts
|    ├--- cars.component.ts
|    ├--- cars.html
|
├--- selected-car
|    ├--- selected-car.module.ts
|    ├--- selected-car.component.ts
|    ├--- selected-car.html
|
├--- auto-galleries
|    ├--- auto-galleries.module.ts
|    ├--- auto-galleries.component.ts
|    ├--- auto-galleries.html
|
├--- nearest-galleries
     ├--- nearest-galleries.module.ts
     ├--- nearest-galleries.component.ts
     ├--- nearest-galleries.html

Note: This is just a simple example, my application better fits a modular structure :)

Angular Docs have some recommendations to this in their Style Guide:

<project root>
  src
    app
      core
        core.module.ts
        exception.service.ts|spec.ts
        user-profile.service.ts|spec.ts
      heroes
        hero
          hero.component.ts|html|css|spec.ts
        hero-list
          hero-list.component.ts|html|css|spec.ts
        shared
          hero-button.component.ts|html|css|spec.ts
          hero.model.ts
          hero.service.ts|spec.ts
        heroes.component.ts|html|css|spec.ts
        heroes.module.ts
        heroes-routing.module.ts
      shared
        shared.module.ts
        init-caps.pipe.ts|spec.ts
        text-filter.component.ts|spec.ts
        text-filter.service.ts|spec.ts
      villains
        villain
          ...
        villain-list
          ...
        shared
          ...
        villains.component.ts|html|css|spec.ts
        villains.module.ts
        villains-routing.module.ts
      app.component.ts|html|css|spec.ts
      app.module.ts
      app-routing.module.ts
    main.ts
    index.html
    ...
  node_modules/...
  ...

Do keep a flat folder structure as long as possible.
