Image & Character
Building Types Group 1

As a highly visible Group 1 building, the character of the Headquarters (HQ) expresses formality and professionalism. HQ facilities must be designed to reflect their importance and strength while unifying the district with architectural elements and enhancing the context of the setting. Pedestrian movement among buildings is facilitated through the design of the built environment and its relationship to the site and other exterior features.


1. Massing & Articulation

The massing is articulated responding to the building program. The mass accommodates generous daylighting of the interior where appropriate. A strong, easily identified entrance is appropriate for this building. Use of a vertical “tower” form also is appropriate for an entry or other architectural feature. Massing and façade articulation will reinforce the overall design concept, and specific attention to detail is encouraged. Brackets may be used selectively as functional devices and focus on entrances or other architectural features.


2. Roof Style

Sloped standing-seam metal roofing is preferred for most of the roof area. Use overhangs to protect window openings as much as practical. Create large gathering areas at the main entrance. Use multiple roof areas in response to the building program but avoid conflicting or overly complex roof forms and a cluttered appearance. Curved roofs may be used to highlight architectural features or as the overall building form to relate to other flightline buildings, such as the hangar.


3. Primary Entrances

Provide a multi-story covered entrance with integral shading devices to accommodate groups of 20 to 30 people, including sitting areas. Open-sided (versus recessed) covered entrances are preferred. Provide large glazed areas to designate the entrance and a high level of finishes on the exterior.


4. Shading Devices

Use aluminum louver and/or shading devices at windows. Shading devices integral with the building façade also are encouraged. Provide shading devices and canopies at covered entrances for strong architectural presence.


5. Secondary Entrances

Provide a covered entrance to accommodate groups of three to four people, using building mass differentiation and glazing to identify the entrance. Provide coverage to protect openings for utility entrances.


6. Fenestration

The HQ building will use vertically proportioned, punched window openings with aluminum windows, storefront and/or curtain wall to create rhythm on the exterior and respond to the interior needs. Using linear or other shapes as design elements is permissible in moderation. Size openings to optimize daylighting in the interior. Ample use of a curtain wall and/or storefront at primary entrances, vertical circulation, and other areas is encouraged for visual impact and to aid in daylighting.

Elevations: Maintenance Headquarters


1. Environmentally sensitive envelopes, responsive to sun, wind, and water

2. Asymmetric compositions

3. Expressive roof form, responding appropriately to building group

4. Large building masses broken down and articulated

5. Variation of building mass

6. Architectural shading devices to control solar heat gain, especially over fenestration; integrated shading with architecture 

7. Common vertical and horizontal elements to create a strong architectural composition

8. Functional large overhangs focused and integrated into strong entries

9. Well-defined entrance, pedestrian scaled

10. Fenestration patterns that provide natural light for interiors, add visual interest to façades, and connect “outside to inside,” especially at gathering and entry areas 

11. Pedestrian-oriented spaces to encourage walkability
