9 Relevant Planning Guidance Pentagon Centre guiding principles Compatibility Mix of uses Distribution of densities and heights Open space Circulation and pedestrian routes Streetscapes Parking Sustainable design Phasing Guiding principles incorporated into design guidelines Adopted with PDSP and Final Site Plan July 19, 2008 Includes the following major components: Concept Plan Building Guidelines Streetscape and Landscape Guidelines 9

10 Pentagon Centre PDSP Design Guidelines - Concept Plan Mix of Uses Development should not preclude continued use of existing retail Uses should be compatible with adjacent development Allow for a variety of retailers Provide open space areas to allow for civic and community space Densities and Heights Concentrate height and density at northwest corner of the site with lowest density and height mid-block along 15 th Street South 10

11 Pentagon Centre PDSP Design Guidelines - Building Guidelines Massing, Scale and Form Follow guidance in Concept Plan regarding appropriate locations for density and height Respect low-rise residential community across 15 th Street South. Incorporate clearly defined base, middle, and top Use upper story elements to visually engage pedestrians Use step backs in large buildings, particularly along 15 th Street South, to create a pedestrian frontage Site buildings to accommodate pedestrians and provide clear orientation to public streets, plazas, and adjacent buildings 11

12 Pentagon Centre PDSP Design Guidelines - Building Guidelines Architectural Elements Design a landmark building at the Metro Station Address all sides of the building Utilize architectural treatments to communicate differences in uses of different floors Define clear building entrances Locate loading and delivery areas to minimize programmatic and visual impact Integrate environmental sustainability and energy efficiency throughout all aspects of building design 12

13 Pentagon Centre PDSP Design Guidelines - Building Guidelines Materials Utilize exterior building materials appropriate for the architectural style, use, and theme of the building Vary materials to provide visual interest Use materials that relate to surrounding development with regard to scale, color, rhythm, and proportion Change materials at interior corners or at the horizontal plane Use materials creatively to integrate existing development with new construction Use color accents that are complementary and color palates that are compatible 13

14 Pentagon Centre PDSP Design Guidelines - Building Guidelines Design of Building Tops Utilize roofing/penthouse equipment to add character and style to the building where appropriate Incorporate green roofs to limit heat island effect Organize and screen rooftop equipment that may be viewed by residents, where possible 14

15 Pentagon Centre PDSP Design Guidelines - Building Guidelines Characteristics of Ground Floor Retail Locate buildings adjacent to the sidewalk along retail facades Design storefronts to promote a sense of entry Use windows to create an open and inviting atmosphere 15

16 Pentagon Centre PDSP Design Guidelines - Building Guidelines Treatment of Above Grade Parking Garages Maintain active street uses in front of above grade parking structures Buffer above grade parking structures with retail or other active uses Provide a unique design for the facades of above grade parking structure within Building A to blend in with the architecture Screen the exterior of the Building D parking garage through the introduction of green screen walls 16

17 Pentagon Centre PDSP Design Guidelines - Building Guidelines Signs Encourage unique project identification signage to reinforce character and branding of Pentagon Centre Use on-site directional signage to help orient pedestrians to and throughout the site Design retail tenant signs to distinguish it from other building uses Provide wayfinding signs that are helpful to visitors and not distracting or impeding on pedestrian or vehicular traffic Locate rooftop signs such that they do not face residential neighborhoods, particularly the community across 15 th Street South 17
