The Board shall examine the architectural plan and may employ consultants to assist in evaluation. The applicant's architect shall explain how the plan complies with the criteria of this section. While the chosen architectural style is important, the Board shall emphasize authenticity, scale, accuracy, integrity and detail of design as well. Such elements as roof pitch and geometry, gables, dormers, window design and recess, doorways, rails, porches, gutters, eaves, louvers, garage doors, pillars, sills, planters, etc., shall be scrutinized for design detail, accurate reproduction, appropriate scale, harmony and visual integrity. The Board shall reject designs which incorporate such elements as blank walls, exposed foundations, shallow roof lines, plastic mullions, frail chimneys, flush windows, aluminum stacks and erratic placement of windows and doors, etc.
