SEATTLE — The new headquarters of Weyerhaeuser seem an exception to other office buildings in this waterfront city. Instead of a tower on a busy street, this new corporate base is a horizontal structure with a front door that opens onto a public park.

Tucked inside a group of 19th-century buildings, the steel-and-glass home of Weyerhaeuser, a wood products and timberlands company, is almost hidden by a row of trees.

The company’s relocation speaks to the changes that Seattle is experiencing in attracting companies, especially in the technology field, as well as the growing interest nationwide by companies in settling in urban environments to recruit talented employees in a competitive market.

Weyerhaeuser, founded in 1900, moved from a forested 400-acre spread in suburban Federal Way, about 22 miles south of Seattle’s central business district. Since October, the company’s 700 employees have worked in the new building, which has a half-acre footprint and is in the historic Pioneer Square district, just south of Seattle’s downtown area.
