The architectural treatment of the structure, whether for residential or nonresidential buildings, shall be designed to convey the character of the country with pitched roofs and facade treatments typical of a residential, estate or farm-like structure. Rooflines can vary by the alternating use of dormers, stepped roofs, gables or other roof elements to reinforce modulation or articulation of facades. Accessory buildings, such as workshops or garages, should also have pitched roofs and present as detached residential garages or as barn-like structures. The sides and rears of all buildings shall be finished to convey the residential country character. The overall design concept shall avoid standard suburban strip commercial characteristics with regard to building or site plan features, and parking areas shall be prohibited in front setbacks.
