Architecturally Compatible. Building design and/or materials that are in harmony with, and do not negatively alter the character of, the existing built environment in the neighborhood. A design or material/color selection is compatible when it does not strongly deviate from its parent building or the overall character of the neighborhood. To be compatible does not require look alike designs, but rather designs that reflect some aspects of its parent building or historic structures in the general vicinity, such as scale of windows, overhangs, building materials, patterns of siding, roof slope. Conversely, incompatibly occurs when an architectural design, landscape design (including fencing) or accessory building proposal is aesthetically harsh or overwhelming in comparison to surrounding historic structures.
