Owners of a mid-rise Class A office building in downtown Boston won’t have to search for a new anchor tenant following a deal announced Monday, but they will have to add a multi-million-dollar amenity.

Audit, tax and advisory firm KPMG has signed a long-term lease renewal with ASB Real Estate Investments to keep its offices at the 220,000-square-foot 2 Financial Center, just blocks from South Station.

Lincoln Property Co. Boston’s Jeffrey Moore along with John Miller and Brendan Miller represented the landlord, ASB Real Estate Investments, in the lease negotiations. Cushman & Wakefield’s Jay Driscoll, Barry Hynes, Mike Joyce and Pat Murphy represented the tenant.

“We are excited about continuing ASB and LPC’s longstanding relationship with KPMG,” ASB Senior Vice President Brodie Ruland said in a statement. “As part of the deal, we are adding a high-end roof top amenity space and renovating the lobby.  Combined with KPMG’s credit, these upgrades will help solidify Two Financial as one of the premier boutique assets in the market.”

“ASB and LPC are pleased to have extended what we view as our partnership with KPMG as anchor tenant at Two Financial Center. Ten years ago, when we began construction and signed the original lease with KPMG, this commitment to a longer term is what we had envisioned and hoped for,” said Jeffrey Moore, senior vice president at Lincoln Property Co.

Located at the intersection of Essex and South Streets, 2 Financial Center offers tenants on-site valet parking with an upcoming multi-million-dollar capital improvement plan that includes the addition of a roof deck designed by Arrowstreet and Copley Wolff Design Group and lobby upgrades. The roof deck will feature outdoor dining areas, casual seating with fire pit and trellises, urban landscape design with sweeping views of Downtown Boston, Back Bay and the South End. The lobby renovations will introduce soft seating areas and hotel-like amenities. Ownership hopes to secure a coffee/juice bar with grab-and-go food items and create tenant collaboration spaces.

“By doubling down on our investment in Boston and enhancing the utility of our workspace, conference facility, and innovation space, we are further extending our ability to provide our current and future clients with the critical thinking, solutions and advanced technology they need to compete and lead in their markets.” KPMG’s Boston Office Managing Principal, Darren J. Donovan said in a statement.
