Philly YIMBY is launching its first annual December Development Countdown of the 31 tallest buildings proposed or under construction in Philadelphia. Number 31 on the list is 20th+Arch, a 260-foot-tall, 15-story office building planned at 2000 Arch Street in Center City West (alternatively in Logan Square). Developed by Parkway Commercial Properties (aka the Parkway Corporation) and designed by L2P Architects, the building will offer roughly 400,000 square feet of office space. No construction work has yet taken place.
The site sits two blocks north of the 565-foot-tall Commerce Square twin towers, designed by I.M. Pei and built in two phases in 1987 and 1992. The proposal site is currently home to an active parking that is managed by Parkway Corporation, the building developer, which has been marketing the site for some time along with Brandywine Realty Trust. As of now, the parking lot is still fully functional and the Parkway sign is still standing along with the booth on the north side of the site. It is unknown when work will start.
The proposal was revealed early last year with a rendering and details on the structure, including an announcement that the building will have an out-of-state tenant. The latter bit of news gained attention, as few major companies have established their headquarters in Center City since Comcast constructed its skyline-topping towers during the last two decades. Speculation circled that the anchor tenant will be Chubb, an insurance company headquartered in Warren, NJ.
Center City West and Logan Square to the north are seeing an influx of planned and under-construction developments in the 200-foot and 300-foot height range that will transform the area. The Parkway Corporation is developing another project to the southwest at 2222 Market Street, where the on-site parking lot has already been torn up in preparation for the construction of the 318-foot-tall office building.
No completion date has been announced, however the construction period is planned to span 14 months, meaning the building may be completed by 2022.
