The NPL Shop can best be reached by walking up OHara St to the front entrance Allen Hall. Once you enter into Allen Hall, walk straight up the stairs in front of you and then straight down the stairs at the top of the first landing. Once you are down the stairs, exit outside and turn right. You should see a door with a sign that says ‘Physics Machine Shop”. Simply follow the signs to the Shop. You can also get there by walking up University Drive and entering Old Engineering Hall. Go down the stairs through the double doors and take the elevator on your left down to the first floor. Turn left when you exit the elevator and then take an immediate right through the double wooden doors. Continue through a second set of doors and turn right as you exit. The Shop entrance should be right in front of you.
