A controversial apartment development that played a part in the Liberal Party's recent election loss of Prahran to the Greens has launched, with homes selling for around $1 million.

Developer Lend Lease's 2.5 hectare site on Orrong Road became a political headache for the former Liberal government.

Entrenched local opposition to the 448-apartment proposal prompted 600 objections to Stonnington Council, and a drawn-out planning battle that included a Supreme Court legal challenge.

Disgruntled residents campaigned against the development's density and building heights, which will rise between four and 12 storeys.
