Costain is building the £80m Parkway retail scheme for Standard Life.
Now workers at the adjacent St James’s Place Wealth Management office have lodged complaints about the effects of construction work.
Yasmin Litchfield, facilities manager for St James’s Place Wealth Management told Newbury Today: “We have contacted Costain about the seasickness issue and the noise, but we don’t want to blame them for the problems.
“We have also had render fall off the top of the building, and have a large structural crack in our basement which I am now in the process of having repaired.”
A spokeswoman for Standard Life Investments said Costain takes all complaints seriously and would respond to all correspondence accordingly.
