"With this lease restructure Sonnenschein has firmly secured a long-term leasehold at a signature Washington address with room to accommodate its growing Washington presence," says Tom Doughty of Spaulding & Slye Colliers, who represented Sonnenschein in the deal with colleague Greg McCavera; Richard Nelson stood in for property owner Hines Interests.

Sonnenschein began its occupancy in the building with 28,000 sf, relying even then on Spaulding & Slye's assistance. The firm increased its take of space to 80,000 sf in 2001. Financial terms of Sonnenschein's lease restructure are not being disclosed; however, class A office space in the city's central business district goes for an average of $38 per-sf, according to Advantis Real Estate Service Co.'s Mid-Year 2004 Office Report.
