Cuckoo Estate

A Memory of Greenford.

Has anyone got any photos of the prefabs on Cuckoo Estate? I would love to see them. I lived on the estate as a small child and my memories are vague, it would be nice to refresh them.
Also just outside of the estate I seem to remember an avenue with trees either side, at the end of the avenue was an old building with what i can only presume had old dungeons or cells. My brothers and I used to play in this building, can anyone shed some light on what this building was?
