The first phase of the project includes two residential towers, with 22 and 23 storeys, offering a total of 464 apartments. The buildings will feature outdoor terraces, rooftop garden space, a swimming pool and a gym.
The project has employed extensive prefabrication techniques in the solutions for the building façade, services and bathroom pods.
Knight Dragon appointed Mace for the £150M project in 2015.
Bob Coe, Mace project director, said: “The topping out of a project is a significant milestone and we're delighted that for our first venture with Knight Dragon on the Peninsula we are able to celebrate this achievement.
“It's also pleasing to reach this milestone ahead of programme and I'd like to thank all those who have contributed to successfully reaching this point in the project. In particular our thanks go to A J Morrisroe who have built this frame for us so quickly and safely.
“Clearly without their outstanding effort, today would not be possible. Today's achievement enables us to look forward positively to the successful completion of the project next year.”
The project is expected to be complete in 2018.
The £8.4bn Greenwich Peninsula scheme will provide 15,720 new homes in seven new neighbourhoods.
