Renovation plans have been revealed for the home of a slain NYPD detective on what would have been his 33rd birthday. 

The Stephen Siller Tunnel to Towers Foundation will remodel Detective Wenjian Liu's home in Brooklyn for his family. The house will get a new roof and windows, landscaping and new air conditioning, among other things. 

Tunnels to Towers says it's all possible because of the public's generosity in making donations following the fatal shooting of Liu and his partner, Detective Rafael Ramos, in Brooklyn back in December. The foundation received more than $1 million in contributions from around the world to pay off mortgages and renovate homes for both men. 

Liu's widow spoke on behalf of their family at a news conference before construction began, thanking everyone for their support. She also translated for Liu's father, who said in part, "If there is a place to call home, there is a life to have happiness."
