Editor Camera Issue

I do not know wether this is the right thread to post this in or not, moderators can feel free to move if required. I have gotten a simple issue in a few of my scenes and projects, (not all) which makes me unable to get close to objects or it will hit it. Almost like my free camera in editor mode is larger then it is. You know when you go past a object you will eventually go through it and see the other side. This happens when im like 3 metres away from the object. As mentioned, this only happens on a few scenes and projects and I am sure this has nothing with the map scaling to do, please help. I should also mention that this happens with all objects as well as the terrain. (Both ground and walls). Thanks in advance.

The following picture is a drive-way and a garage door. This issue does not happen when in-game but just when editing the map. As you can see, my camera is about 1-2 metres away from both the ground and the garage door, still this happens. It should not do this until you actually reach it and you're inside or beyond it.

The scene view's camera near clip plane is dynamically adjusted to fit the object(s) last focused on. Try selecting the garage door and pressing "F" to focus on it, then manipulate the camera as you would normally.

 

Thanks that helped, have a great day
