Timber frame party walls structural noise, any solution?

heritz

Relatively new terraced house built in 2017 with timber frame party walls. There has always been a lot of structural noise coming from the first floor of the house next door. No voices, music or anything, it just seems like the houses share the same timber frame structure, so any minor vibration like walking or closing doors can be felt here. This is exacerbated by the fact that their first floor is tiled.

This is driving us bonkers as the neighbours stay up until 2-3 in the morning. Drop a phone on the floor at 2 in the morning and it will wake you up.

Is there any solution for this apart from selling and moving the heck away from here? I would assume that somehow separating the timber frame structures would be a major undertaking but I thought I'd ask in case someone has gone through the same.

Sell up and move.
Sorry, but that’s the only thing I can advise as you fix this issue without going back to the fabric of the structure on both sides.

I spoke to two soundproofing companies about a similar sound issue and both said similar solution. One did mention that improvements can often be made but can be very expensive relative to the gain unless you do it yourself.
