C172 flight instructor reported the aircraft's right wingtip struck a hangar while taxiing to the FBO's maintenance hangars to fix the transponder. The nav and strobe light was damaged by the impact.

Narrative

Me; the Flight Instructor; a student; and an observer got into the aircraft and performed the before-start and taxi checklists and received the ATIS information and our clearance. When we went to input our squawk code we noticed our transponder was not working. We tried to troubleshoot the issue with no success; and called our Company Dispatch and asked them what we should do. Dispatch told us to taxi to the maintenance hangars; and we clarified with them the location of the hangars since we had never taxied there before. They told us ask Ground to taxi to [the] FBO; so we did just that and Ground told us to taxi from our location; Southeast Ramp in ZZZ; to [the] FBO via [Taxiway] XX; Runway XXR; and right on [Taxiway] XY. After taxiing right on [Taxiway] XY; we crossed into the non-movement area and brought the plane to a stop; called Dispatch again; and asked where exactly to bring the plane. Being past [Taxiway] XZ they told us to taxi on the second row of hangars to the maintenance area. I had the flight controls and the student was keeping an eye on the airport diagram and outside of the aircraft as we took a left on the second row. Reaching the end of the row we took another left where two square hangars are and there were planes immediately to the right of us and to the left about 100 ft. in front of us. We cleared the planes and a dumpster to the right of us by maneuvering the plane more to the left closer to the other aircraft off the left. Taxiing at a brisk walking pace of around 5 kt.; all of our attention was focused on clearing the left wing with the plane on the left. I looked up in front of me as I asked the student if we had cleared the left and as soon as I asked that we struck the right wing tip with a hangar off to our right. It was a minor thud we heard and felt. We got out of the plane and found the nav and strobe light shattered. Taxiing in an unfamiliar area and being too focused on one certain thing led to this minor incident.
