20 College Street, Ammanford

We heard loud noises coming from the property next door. It sounded like an air chisel breaking stone, and the noises would sometimes go on for many hours.

The noises were confirmed by John Francis Estate Agents, who stated that the work being carried out at 22 College Street damaged one of their walls.

During one bout of particularly heavy drilling and chiselling, the alleyway seemed to be shaking underfoot.

Cracks had appeared in the alleyway and in the side walls of both 20 and 22 College Street.

The rear wall of Sophia Nails:

When I looked in the basement, I could see some cracks in the wall that faced the shop that used to trade as Sophia Nails.

I focused on the noises that concerned me, not the noises of the air chisel.

I carefully opened up the cracks in the basement wall and cleared away the debris.

I made holes in the basement wall and the floor of the basement.

In the side wall of the basement facing 22 College Street, a bright light was seen coming through the wall – even though that area is underground.

I was determined to get to the source of the noises. I used voice recorders in different places, both inside and outside my house, to establish where the noises were actually coming from. The noises were clearest in the basement area of my former house.
