Brigade Models has been hard at work with the Imperial Skies Kickstarter but as things are coming back to normalcy they have released a few wonderful bits for 15mm science fiction.
The release is a set of outbuildings for their Advanced Buildings. These are perfect for small habs, workshops, sheds or other light utility structures. The second set is a bunch of "widgets" for use on the tops of the Desert Buildings, though I see no reason they wouldn't work on other structures. If you are like me, you love these sorts of add-ons for your own scratch built terrain.
