I have 3 story single column load bearing house. Recently I made a room at the terrace. After the construction my house is vibrating all the time. My house is between 2 houses; there is no gap in them. Because of the vibration I feel very anxious; what to do? The contractor is saying it is normal. But I never felt this before. I am attaching a picture of my house (click to enlarge):

possibly a harmonic tremor? I have seen it rip bridges apart...has something to do with certain vibrations and wavelengths of the vibrations. When they are tuned just right they can be quite destructive.

Suggest to measure vibration

Vibration meter is an app called seismograph or seismometer

Can be a smartphone app, or a sensor that's got Bluetooth enabled for you to collect the data. ( https://blog.endaq.com/6-ways-to-measure-vibrations )

Then you can measure in your room, and in shared spaces and at your neighbor's.

Btw, is it constant? Does it go away at night?

I would be concerned, it may cause cracks in the building walls - either internal or external - where specifically depends on the geometry. If measurements are taken then this may help to fix it.
