It depends on the layout of the hangar and the way that aircraft are often crammed in. Poor layout and too many aircraft are both recepies for hangar rash. Sadly the high costs of hangarage and the shortage of space means that there is seldom enough space.
Personally I am in favour of individual or T hangars. There are companies who will build a typical light aircraft hangar for around 6-8 thousand pounds but that implies that there is space to build it and that the airfield owner is willing to rent the space at a reasonable price.
