The applicant shall submit proposed architectural drawings and renderings of the proposed structure, including exterior elevations, which shall project a residential rather than a commercial appearance. This architectural documentation shall be in sufficient detail to demonstrate discernible compatibility between the new construction and the existing on-site development and structures; provided further, the applicant also shall document a design which, in scale and bulk, is in keeping with existing buildings on adjacent properties and compatible with the surrounding character and neighborhood in which the guesthouse or inn is located.
