Residents have complained that contractors wearing casual clothes ruined their weekend by causing unwanted noise.
One woman reported the incident to the Health and Safety Executive (HSE). She told the ECHO the workers "ruined her weekend" by starting work at around 7.30am on a Saturday and Sunday.
The incident happened at the former Coconut Grove site in Tuebrook. The site is currently owned by Widnes based company Sourced Development Group (SDG), which plans to build an apartment scheme at the site on the corner of West Derby Road.
