Preservation Design Guidelines
In order to provide objective standards for communities to evaluate the appropriateness of alterations to their buildings, the Collaborative prepares design guidelines for historic structures and districts. Design guidelines identify and illustrate the site and building elements that are most significant, such as building height, distance separating structures, and size and shape of the openings. These guidelines provide the delicate balance that is necessary to a changing community; the difference between strict adherence to particular architectural styles and incompatible new construction. The use of design guidelines can ensure that visual continuity of the streetscape will be maintained, without unduly restricting the creativity of the designer.
