    Skyline Variation

    undefined
    Is anyone aware of zoning regulations that require buildings to have spires, towers, domes, minarets, pinnacles, tapering, etc.to provide skyline variation?

    We just adopted the following for our Village Center area:

    Dennisport Village Center District Area A

    The maximum height of buildings or structures, other than accessory rooftop equipment discussed below or special architectural features, is 42 feet or three stories. The third story shall be a portion of the building, having a floor area, with a vertical dimension of at least seven feet three inches (7’ 3”), measured from the finished floor to the finished ceiling. This third story area shall not exceed 65% of the floor area immediately below.

    Roof pitch, visible from the streets (face to full allowable height) must be between 6:12 and 12:12, except that roof pitches towards Route 28 shall be between 8:12 and 12:12. Roof pitch shall start no higher than the finished floor height of the third story. The gabled end of all buildings must be peaked and cannot be flat. Parapet walls shall not be higher than 28 feet tall.

    Buildings or portions of a building mass over 75 feet wide are encouraged to divide their elevations into smaller parts. A pronounced change in massing, pronounced changes in wall planes and introducing significant variations in the cornice/roofline are all possible methods to accomplish the desired divisions of elevations into smaller parts.

    The roof pitch may be interrupted by “dog-house” or “eye-brow” style dormers or sky-lights to provide for daylight and ventilation.

    Accessory rooftop equipment may extend to 46 feet, provided that they are set back from the exterior wall(s) by at least 10 feet, and are enclosed or screened with materials compatible with the building and are not visible from the ground. Accessory equipment may not exceed 20% of the roof area.
    Planning is much like acting, as my old theater professor used to say, "If you sin, sin boldly, only you know if you are ad libbing." I follow this adage almost daily.

    San Francisco I think has some regs about that. I think I remember a professor talking about a "fancy tops" requirement there.

    "Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country."

    That would eliminate the downtowns and neighborhood commercial districts of many towns. Most of the old commercial buildings would have a flat roof, but varying heights, cornices, pediments, and architectural decoration created diversity. I would recommend a design guideline (rather than an ordinance) that explains the goal of having a diverse skyline, and offering some very general suggestions about different approaches the developer might take toward meeting this goal.

    We use a prescriptive method but give the architect or would be architect a variety of ways to fulfill this particular regulation. Emphasis is on breaking up a *blah* skyline, many ways to do this, not as simple as saying yes or no to a pitched or flat roof.

    Roofline Choices (All buildings shall use one or more of the roofline options)
    1. Sloped roof. Use of a roof form with a pitch no flatter than 5/12. Rounded, gambrel, and/or mansard forms may be averaged.
    2. Modulated roof. Use of features such as a terracing parapet, multiple peaks, jogged ridge lines, dormers, etc., with a maximum of 100 feet uninterrupted roofline between roof modulation elements. Modulation elements shall equal a minimum of at least 15 percent of the roofline on each elevation. The maximum shall be 50 feet of uninterrupted roofline along the eave between roof modulation elements in C?1 Districts and on sides facing residential uses or districts. Roof forms with a pitch flatter than 5/12 are permitted with this option; provided, the appropriate modulation is incorporated.
    3. Corniced roof*. A cornice of two parts with the top projecting at least 6 inches from the face of the building and at least 2 inches further from the face of the building than the bottom part of the cornice. The height of the cornice shall be at least 12 inches high for buildings 10 feet or less in height; 18 inches for buildings greater than 10 feet and less than 30 feet in height; and 24 inches for buildings 30 feet and greater in height. Cornices shall not project over property lines, except where permitted on property lines abutting public right?of?way.

    Check out the design standards in Overland Park, Kansas...

    It's a big PDF to download, but it's a great resource.

    Vancouver, B. C. had a very interesting master planning concept that tied building heights and design to the mountain backdrop.
