Each building was 11 or 12 stories tall, and sheathed in glass and steel. Further details about the preliminary design emerged two weeks later. The "Washington Post" reported that the northwestern park was now slightly larger at , office space had soared to (up from in November 2006), and only 1,640 underground parking spaces were planned (down from 1,700 in November 2006). The number of housing units had fallen to 665 from 686 in November 2006, which included 211 condos ranging in price from $700,000 to $1.4 million. Retail space had also shrunk, to (from in November 2006). Four of the buildings had retail on three stories, while the other two had retail on just two. Gould's plans for the northeast corner of the site were still unsettled, but Hines and Archstone executives said it was well-suited for office space and a boutique hotel. The look of the new buildings also was made public at this time. Foster and Partners designed both office and both condominium buildings, while Shalom Baranes designed the apartment buildings. All the buildings were "streamlined in glass and metal". The office buildings were clad in a double layer of glass and metal designed to move to reflect sunlight. The condo buildings had glass curtain walls, and balconies extended uninterrupted across the facade (although metal grilles separated each unit's balcony from the next to create some privacy). Vertical slabs of precast concrete extended vertically up the facade to help break up the monotonous glass wall. The apartment buildings (by lead architect Robert M. Sponseller) also featured glass curtain walls, but the balconies (which did not extend across the facade) were clad in terra cotta and the corners of the buildings were covered in glazed tile in a rhythmic patterns reminiscent of 22 West (a luxury condominium located at 22nd and M Streets NW and completed in 2008). Setbacks were used on the upper floors along the pedestrian interior spaces. The "pedestrian street" (nicknamed "9 1/2 Street" by the architects) was to be paved in granite, with each retail front jutting into the street at different depths and adorned with varying signage. The goal was to mimic a street which had been built at different times and in different architectural styles, without completely losing a uniform architectural style that would unify the storefronts visually. The narrowness of the pedestrian area was intended to create a more human-scale urban experience similar to that of New York City.
