WASHINGTON, DC-Development of the mega 1,500-room Marriott Convention Center Headquarters Hotel takes a big leap forward as Tishman Urban Development Corp. comes aboard as the developer and project manager.

BOCA RATON, FL-Little Switzerland Wholesale Inc.'s 10-year office lease here is estimated to be worth about $4.6 million. The specialty retailer, owned by Tiffany and Co. of New York, carries luxury items, including jewelry, precious gemstones and fragrances.

TUALATIN, OR-Crate & Barrel commits to opening its first Oregon store at the planned $150-million development that would fill the 29-acre former Durham Quarry next to Interstate 5 here with 680,000 sf of office and retail space. The developers' next hurdle is a Sept. 8 City Council hearing to decide the voracity of several appeals.
