I'm an intern working on an intranet for a small company that may potentially expand in size. The company has a few departments with an engineering department that has different fields. They also have project sites.

I was planning on structuring the site as follows:

    Home(site collection)
    -Projects (site collection)
    --project x(subsite)
    --project y(subsite)
    -Departments(site collection)
    --Engineering(site collection)
    --- Engineering field x(subsite)
    --- Engineering field y(subsite)

Is it possible to have site collections inside other site collections? Is there a better way to structure this?

Their are many things to think before the designing intranet site.

  • Number of user
  • usage type( collaboration, project management etc)
  • security( unique permissions or shared), do you want HR employee access full site or vice versa.
  • Storage

Once you have above then you can design a site collections.

You cant have a site collection in Site collection rather you can create a Sub-site under a site collection using the team, proj, blog etc templates. In you scenrio you can do like this.

Home(site collection)
    -Projects (**Subsite**)
    --project x(subsite)
    --project y(subsite)
    -- Engineering field x(subsite)
    -- Engineering field y(subsite)

this picture will explain you the same thing,

It is upto requirement, sometime a separate site collection is required for each department.

  • So it seems that it would be a better idea to not have home be a site collection and then everything would just be subsite of home. Then in the projects, each project would be a site collection where only members of the project have access to it. Commented Jun 4, 2015 at 16:53
