The Fairfax County Board of Supervisors in Virginia, US, has approved the 23-storey tower in Reston proposed by the developer RTC Partnership.
The proposed new tower will be built in the area cleared by the demolishing of the existing five-storey Reston Times office building.
The 325ft building will be 125ft taller than any of the existing or proposed surrounding buildings.
With the penthouse, the tower will be three stories, 30ft taller than One Freedom Square which is currently the tallest building in Reston.
The tower will replace an existing 61,000ft² office building at 1760 Reston Parkway, known as the Town Center Office Building.
Plans include an outdoor 38,000ft² terrace and green roof on the sixth floor featuring outdoor seating from a restaurant.
The building is expected to achieve LEED Silver certification and will have a mechanically ventilated parking garage.
The developers will also reduce the number of parking spaces and the savings ‘will be dedicated to mass transit’.
Upon completion, the building will be taller than any other current building at Reston Town Center.
Fairfax County Planning Commission approved a site plan in June 2012 by voting 7-3 in favour of the building.
