Creepy Vernon Building, High Wycombe, with two gated Lifts

This is an industrial building very near to the town centre (as shown in video).

I couldn't find out much about the building's history, but it must date from the 1950s, or even before? - look at the wood paneling above the door at 3:58, any guesses at the building's age?

The building has 4 floors (G, 1 - 4), and has two gated lifts (slam-shut doors). These are at either end of the building.
The one at the front was being loaded up with wood at the time by a guy with a van in the loading bay, so I could only ride it. Actually this loading bay is huge, and has a raised 'dock'.
The lift at the back is the one that I used. When I returned to the ground the outer doors were opened by a guy that was waiting to go up!

The lifts are deep, but the ceiling height is low. By the look of the Car Operating Panel, these are probably not the originals, but the call buttons on the landings may be. They are also very dark with totally inadequate lighting. As these gated lifts are the only lifts in the building, the occupants must have to use them day-to-day to get to their businesses, or walk!

I had to use the light on my cameraphone AND boost up the video levels in the editing software.
The corridors are dark, creepy (notice the fickering fluorescent tube lamp at 4:04!) and there are some unused sinks in the corridors at each end. This is a creepy building which is still in use. Wouldn't want to pay much money to rent out one of these units! There must be plans to demolish this building, but it would be a shame, as buildings like this that are still occupied are rare these days.

Interesting building though, and well worth exploring!
