The man later died in hospital.
A 38-year-old woman and a 37-year-old man who were arrested on suspicion of murder by detectives attached to the PSNI’s Major Investigation Team remained in custody late on Monday.
Detective Inspector Jill Angus said police received a call for assistance from the Northern Ireland Ambulance Service just before 1am on Monday.
"A man, aged 42, was located at the property with serious injuries. Medical treatment was provided at the scene – before he was transferred onward to hospital.
“Sadly, the man then passed away due to the extent of his injuries.
“A 38-year-old woman and 37-year-old man have both been arrested on suspicion of murder, and remain in custody at this time, assisting detectives with their enquiries.
“The local community can expect to see an increased police presence in the Wardsborough area as officers conduct further enquiries into what happened – cordons also remain in place.
“Although our investigation is at an early stage, we are working to establish the circumstances surrounding the man’s death and to determine exactly what happened.”
Sinn Féin councillor Declan Lynch said: “It is heartbreaking that a man has lost his life in Lisburn this morning. My thoughts are with his family and friends at this very difficult time.
