Houses upon lots within such specified distance from each other shall be considered substantially similar in exterior design and appearance if they have any one or more of the following characteristics in common:

In addition to the requirements set out in paragraphs 1 through 5 above, there shall be not less than eight individual basic house designs within each open space zoning development and each basic house design shall provide alternate roof elevations, window and door locations, placement of garages, and other similar features. Wherever feasible, not more than two houses of the same basic design shall be constructed along both sides of a common street in a single block.

To insure conformity with the provisions of these regulations and to thus increase and protect respective property values of the dwellings with an open space zoning development. No building permit shall be issued for the construction of any residence therein unless and until the full floor plan and elevations with a general description of the exterior appearance and front treatment of the said building shall have been exhibited to the zoning officer, together with a site plan showing its proposed location on the lot. Such plans, elevations, design and site plans shall be prepared by a licensed engineer or architect and shall be considered in the context of the immediate neighborhood to determine its compliance with the distance regulations herein provided, and its conformity with these regulations. If there is any controversy regarding such compliance, the applicant shall have a right to present the matter directly to the Greenwich Township Land Use Board, which Board may grant relief to the applicant, after hearing, when, in its opinion, such relief can be granted in a manner not detrimental to the public interest and provided such relief will not substantially impair the purpose of these regulations or otherwise impair the zoning plan.
