Is there anything showing up on https://www.roadworks.org
Only works in certain areas, and I think you need to change the date range (I think it searches today only by default).
Seems odd to say it's for superfast broadband if they are only installing a joint box.
If some parts of the village are a considerable distance from the cabinet and get very low speeds then additional infrastructure could be getting added to increase their speeds (infill cabinet, FTTP).
It's extremely unlikely they would install FTTP for anyone 50m from an existing fibre enabled cabinet though. If there is work going on to increase speeds for some in the village I'd be surprised if you were included in any plans.
