Although it's the Dulles corridor and not directly in Tysons, the Restonian
blog writes about a 23-story office building planned for 1760 Reston Parkway, by RTC Partnership LLC.
Here's the link for the blog posting: http://www.restonian.org/2011/11/res...per-moves.html
I think the building is attractive enough and it will provide more density by one of the metro stations on phase two of the Dulles Silver line extension.

Here is some information from the architectural firm's website.
"Reston Section 87, Block 1
Planning and architecture services are being provided by Pollēo Group for the redevelopment of the 2.36 acre parcel located along Reston Parkway at Bowman Towne Drive immediately adjacent to The Spectrum at Reston Town Center.
The project includes a signature, high-rise office tower of approximately 420,000 square feet with ground level retail and structured parking. Contemporary architecture will generate a focal point along Reston’s main avenue and will serve as a northern anchor for the continued development of the Reston Town Center business district."
