Hi all,
I finally found the answers.
FabLab Essex has closed. 
They were too far from the local transport hubs for easy access, and the local parking was non-existant as there was an MOT test centre next door, which consistently blocked access to the two parking spaces that the FabLab had set aside for their use.
They tried to relocate, but couldn’t find anywhere that was in their budget levels.
This is a consistent problem for a large number of organisations that are within spitting distance of transport hubs near London.
Side-effect of the London property bubble.
There is a group of people that are trying to get another FabLab up-and-running in East London, but they haven’t found any properties that would work, due to the over-priced rents required.
Add in the actions of the property developers who are converting industrial/commercial estates into residential land for luxury-flats/commuter-villages, and you get the situation that we have now.
Sorry to have to share the bad news.
If anyone does come across places that would be interested in renting out buildings in the East London area, then please let me know, and i’ll pass the messages on.
Thank you.
