People living at The Triangle have complained about cracked walls and ceilings, water leaks and problems with stairs and doors.
The 42-home scheme by Haboakus is a joint venture between McCloud’s firm Hab and housing group GreenSquare.
Residents started moving in last summer after work was completed by main contractor Willmott Dixon.
Spokesman for GreenSquare, Vic O’Brien, told the BBC: “We have had, and we continue to have, some severe problems with building defects.
“They are things which we weren’t expecting from the builder and we’re now in the process of tackling all of those.
“It’s bad building. There are hardly any design issues there, it’s to do with the quality of the building works.”
He added that the most “important” problems would be dealt with “in the next few weeks” and all issues would be dealt with by the end of the summer.
A Willmott Dixon spokesperson said, “Greensquare decided to initiate an approach to post completion defects management by opting, against our advice, to take responsibility for this.
“This appears to have significantly hindered communication over matters arising and resulted in us not being made fully aware of issues experienced by residents.
“Providing quality and customer care are essential elements to how we have done business for 160 years, and we are quick to resolve any issues our clients may have post-completion.
“Once we have worked with Greensquare to ascertain the full details of the problems raised, we will work closely with all parties to bring everything to a prompt conclusion.”
