I repeat, the real benefit of this design and the reason for the imposition of the covenant seems to be to ensure a quiet residential area with plenty of light and air. It follows, therefore, anybody who owns property in that area and resides there, have these practical benefits. Any erosion of that plan, as I have said, must lead to an injury in the sense that the benefit must be eroded. I further, however, believe that if one were to approve of the modification in the way that the applicant proposed, it would constitute a substantial injury. It must diminish the beneficial nature of the covenant. Substantial injury would be suffered by a modification to the present scheme. Without finding affirmatively that that is necessarily so, my state of mind is such that I would choose to express it that the applicant has not satisfied me that no substantial injury will be suffered by the modification proposed.
