I have created a building mesh and I decided I wanted to stick another window in the outside. I placed some loop cuts but when I went to delete the faces I noticed there is some grey object within the mesh which is not visible in wireframe mode - any ideas?

$\begingroup$ To clarify its the window directly in the middle of the SS $\endgroup$– hypermind2016Commented Jul 29, 2016 at 21:02

$\begingroup$ This is probably face of other side of the wall. Consider upload .blend file using blend-exchange.giantcowfilms.com $\endgroup$– Shubol3DCommented Jul 29, 2016 at 21:07

$\begingroup$ It isn't unfortunately, in wireframe this appears completely see through exactly the same as the other windows and I've even managed to face the surrounding window frame sides. I've also checked on all of the other walls deleting a face and this very odd grey structure which is unselectable appears. $\endgroup$– hypermind2016Commented Jul 29, 2016 at 21:10

$\begingroup$ Did you try exiting Edit mode for building and checking if there is another mesh in that place ? $\endgroup$– Mr ZakCommented Jul 29, 2016 at 21:12

1$\begingroup$ Have fixed - trying Mr Zak's suggestion I selected it in object mode finally and I had somehow managed to duplicate the entire building structure. Sorry for wasting time and thanks for your help. $\endgroup$– hypermind2016Commented Jul 29, 2016 at 21:26

Unselectable geometry in Edit mode means there's another object in the scene located in the same place. You have several options to continue working on current object without anything messing around:
enter Local View for selected object. Nothing except it will be visible. Note that you can activate Local View for several selected objects, not only one;
exit Edit mode and enter Object mode. From there you'll be able to select another object (you could use Outliner for navigating the objects in the scene in order to find what's needed) and either move it somewhere else or delete it altogether.
join objects, which is done from Object mode too. Thus both objects will be editable at the same time, see Cannot select vertices from different object while in edit mode. Note that you could edit 2 different objects without joining them with MultiEdit addon;
