These paired doors with a transom above are typical of commercial buildings from the late 19th and early 20th centuries. Note the simplicity of the overall design of the entrance. The recessed doors provide weather protection. |
A single door serving a commercial storefront is common practice. This example has no transom but instead has glazing covering nearly the entire door, both to admit light and to permit customers to see into the store. |

It is important not to overlook a historic building's secondary entrances, which may be placed on the main facade or along a rear or side wall. As this doorway illustrates, these entrances often received nearly as much attention to detail as the main entrances. In this example, an additional tall transom provides natural light for an interior stairway. |

Section through typical double-hung window, showing how the upper and lower sash slide past each other while providing a weather-tight fit at the center meeting rail. The exterior of the window is to the right. Note how the sill is sloped to drain water away and how the lower rail is angled to rest flat on the sloping sill to provide a weather seal. |

A double-hung two-over-two window. The lower sash is recessed so it can slide upward behind the upper sash. The upper sash is designed to slide down in front of the lower sash, but in most buildings the upper sash has been fixed in place. |
Appropriately designed wood replacement windows. |

These one-over-one double-hung sash windows, clustered in groups of three, represent typical late 19th century practice. The window proportions, weight of sash members, and glazing patterns all were consciously chosen by the architect as part of the design and should not be altered during repair or rehabilitation. |
![]() | SIGN PLACEMENT AND SIZE Illustrated are four possible directions that signage could take. The most basic approach (A) is that of the sign placed within the transom space directly above the entrance and display areas. For many shop fronts, signage placed on the valance of a canvas awning (B) becomes a possibility. A simple sign board (C) placed above the entrance, would be particularly effective for pedestrian traffic. Graphics, when placed on display windows (D) can also be an attractive possibility. Signage, however, should be limited to only one of the examples shown. This eliminates unnecessary clutter thereby making the signage used more effective. It also is important to insure that whatever approach is used, that its construction, design, and final painting be of the highest quality. |

A simple, traditional, and inexpensive form of signage is to paint or apply individual letters and numbers on display windows. |

Signs painted directly on display windows have been used since the 19th century and remain popular today. They allow considerable flexibility and the opportunity for creativity but must be handled carefully to avoid becoming gaudy or overdone. These signs are particularly helpful for pedestrians and often are used with other signage oriented toward people in cars. |

Individually crafted signs suspended from brackets are a traditional, appropriate form of signage. |

RECOMMENDED | RESTRICTED W/O DDRB APPROVAL | ||
OVERALL BUILDING FORM | Height | - Maintain overall height of adjacent buildings - Continue the established cornice line of adjoining buildings | - Sharp height deviations from adjacent buildings - Breaking the established cornice line of adjoining buildings |
Massing | - Simple, rectangular shapes - Maintain the established mass of adjoining buildings | - Unusual shapes and forms that deviate from adjoining buildings | |
Proportion | - Vertical orientation of the overall building - Repeating rhythm of major architectural elements | - Horizontal orientation of the overall building - Random organization of major architectural elements | |
Scale | - Pedestrian scale that relates to the setting - Small scale details that relate to pedestrians | - Buildings that lack pedestrian scale - Lack of small scale detail | |
Roof Shape | - Compatible with the architectural style of the area | - Pitched roofs on non-residential buildings | |
Materials, textures and colors | - Brick, stone and other traditional masonry materials - Contemporary materials that take cues from adjacent buildings - Combination of materials, textures to create architectural interest - Color used to enhance details | - Metal panels - Construction grade concrete block - Single, monotonous texture that lacks detail - Colors that clash with adjoining buildings | |

Window | - Continue the traditional window patterns of neighboring buildings - Repetitive and ordered placement of windows - Maintain divisions between first and second floors | - Window patterns that deviate from the traditional patterns of neighboring buildings - Random and disorganized placement of windows - Blank, windowless walls on upper stories | |
Signage | - Signage compatible with architectural design of the building | - Signage that disrupts the architectural design of the building | |
SITE PLAN | Setbacks | - Continue traditional setback of neighboring buildings | - Large setbacks that disrupt the overall streetscape |
