Well let's see, from the main head office of ptcl, move towards the motorway and take the first double road to the right. Go a bit further, there will be a street on the left besides a showroom(with expensive cars on an incline), in the street, go straight till you cross a bridge, as soon as the bridge ends, there is a path to the right with their name on it. This is just before the allied bank. I hope that is clear enough
