The Boston-based development company that made a dramatic entry into the San Diego life-science market in November is expanding its local presence with a promise of more to come.

Longfellow Real Estate Partners has acquired two industrial buildings in Sorrento Valley for $15 million from Parallel Capital Partners.

“We at Longfellow view the San Diego life science cluster as ripe for continued growth, so it only made sense to expand our market here,” said Jessica Brock, a partner with Longfellow Real Estate.

In November, the company bought 12 light industrial buildings in what was known as the Inspire campus totaling 318,969 square feet from Parallel Capital Partners for $112 million.

The Inspire site is about a mile from Longfellow’s latest acquisition in Sorrento Valley.

“These little buildings fit perfectly with our other assets, which we just purchased in Sorrento Valley,” Brock said.

The new deal was for buildings totaling 37,555 square feet at 10575 Roselle St., and 10581 Roselle St., in what’s known as the Roselle campus.

About 77 percent of the Roselle campus is occupied and the remaining space will be under-go full lab buildouts.

Over the next three to five years, Longfellow expects to acquire up to 2.5 million square feet of light industrial space in San Diego as the company expands its operations to the West Coast.

“As we look to building a portfolio in order to serve the entire West Coast, you’ll see us continue to buy assets,” Brock said. “They will be in the major life science markets — UTC, Torrey Pines, Sorrento Valley and Sorrento Mesa.”

Deals also are in the offing in San Francisco, Brock said.

San Diego was Longfellow’s first pick on the West Coast because it has room to grow, a vibrant life science community, a strong venture capital market and the universities to provide the talent for the industry, Brock said.

“It is a top tier life science market,” Brock said. “We’ve been looking in San Diego and San Francisco for the past 24 months.”

Longfellow Real Estate’s prior investments have been on the East Coast.

The company is developing a 1.7 million square-foot technology park in Durham, North Carolina in collaboration with Duke University and Measurement Inc.
