Cornerstone Real Estate Advisers said that it completed more than $8 billion in transactions and raised more than $2 billion in capital in 2011.

The Hartford-based firm said its 2011 transaction activity included equity acquisitions and dispositions totaling nearly $2.4 billion; and debt investing totaling $5.7 billion.

Cornerstone said it also raised more than $2 billion in capital from a record number of existing and new global investors for its debt and equity fund products and separate account mandates.

In addition to the firm’s acquisition activity, Cornerstone, on behalf of an institutional client, made a significant investment in the development of Vertex Pharmaceuticals’ global headquarters on Fan Pier in Boston, the largest private commercial real estate development in the country, comprising 1.1 million square feet of waterfront office and lab space.

Cornerstone ended the year with more than $32 billion in assets under management, up approximately 6 percent from the beginning of the year.
