“Welcome home!”

That’s the greeting every KPMG employee gets when they arrive at the firm’s new 800,000-square-foot training complex in Orlando, Florida. Inaugurated in January, the so-called KPMG Lakehouseserves as a professional development and innovation hub for the accounting, tax, and advisory firm’s 32,000 US-based employees and partners.

The Lakehouse offers many amenities for an ideal learning retreat: 800 single-occupancy guest rooms, 90 classrooms and innovation labs, a 1,000-seat auditorium, a 15,000-sq-ft gym, miles of cycling and running paths, and views of Orlando’s Lake Nona. But beyond the physical infrastructure, the KPMG Lakehouse has impressed early visitors because of its attentiveness to details that ensure a guest’s comfort, otherwise known as “experience design.”

“I feel euphoric! It’s a very historic moment,” said KPMG CEO Lynne Doughtie, who spoke to Quartz shortly after the opening. “To have this type of investment in our talent that will fuel our culture and our success for the next hundred years feels really special.”

KPMG spent $450 million to build the Lakehouse, the largest capital investment in the company’s 120-year history. David Turner, KPMG’s chief financial officer, said the proposal for a permanent learning center made sense given that KPMG had been spending more than $100 million annually in hotel expenses for employee training sessions across the US.

Holding workshops in different venues required repeat spending for new signage, tech set-up, and other logistical details.”We realized that we could spend that $110 million to $120 million on our own facility,” said Turner. Along with Laura Newinski, the company’s head of operations, Turner spent the last five years overseeing the Lakehouse’s development.
