Alexandria Real Estate and architect CollinsWoerman presented their plans for 400 Dexter for recommendation to the design review board last night. Those plans call for the demolition of three existing single-story buildings to be replaced with a 12-story office building with 269,700 sq. ft. of office space, approximately 13,800 sq. ft. of retail and 457 below-grade parking spaces. They have goals to achieve minimum LEED Gold and keep in mind the pedestrian experience along Dexter, Harrison and Republican. The tall, canopied cover and a recessed ground level storefront provides an opportunity for outdoor, café-style seating. A plaza area on the south corner and a fifth floor open space give tenants and guests connection to the outside world. Perhaps most importantly, the iconic street clock on the corner will be refurbished and become a centerpiece of the new plaza.
