nants apply, equity forbids that the restriction should still be enforced, when its only effect is to operate disadvantageously to the present owners of the land, to whom the covenants apply. The doctrine announced in
Trustees of Columbia College v. Thacher, 87 N. Y. 311 , 41 Am. Rep. 365 , finds precise application to such case. In Holt v. Fleischman, 75 App. Div. 593 , 78 N. Y. Supp. 647 , this court sustained a covenant which was for the benefit of a dwelling house, as such, and noted the distinction between that case and the doctrine announced in Trustees of Columbia College v. Thacher, supra. Therein, however, the dwelling was still occupied for purposes of a residence, and the enforcement of the covenant was essential to a complete enjoyment of it as such. Here, however, by reason of changed conditions, no benefit can arise in the enjoyment of this property by the enforcement'of the covenant. The same doctrine is announced in
Lattimer v. Livermore, 72 N. Y. 174 . If there were no other reasons therefor, we should regard the radical change and the cesser of use of the property for residential purposes as furnishing a sufficient ground to deny an enforcement of the covenant. In addition to this, we are also of opinion that when the successors of the grantor in the deed tore down the dwelling, and erected'a business block thereon, which extended over, the open space in front of the dwelling house to the building line upon the northerly side of Seventeenth street, it amounted to an -extinguishment of whatever easement had theretofore existed upon the adjoining property. Such act was inconsistent with the terms of the restrictive covenant, its language, and intention. It was a recognition of changed conditions which had converted this street from a residential street, and devoted it to business use. The building which was erected upon this site was itself devoted to business, and was a conclusive act, and conclusively evidenced an intention upon the part of the successors in the grant to disregard and nullify the covenants which had been imposed for the enjoyment of the property as a dwelling. The authorities which hold that such acts are inconsistent with the continued existence of the covenant are numerous.

Nor can the covenant be held to continue and remain operative as an easement for light and air over the restricted space. The Everett House was built in 1856. When it was constructed, no space was left between the Moffat dwelling and its westerly wall, nor were there any side lights in the Moffat dwelling, or, if so, their obstruction by the wall of the Everett House was complete, and was acquiesced in by the owner of the dwelling. The projection of the dwelling house beyond the front of the Everett House was not sufficient to permit of any windows on its easterly side, nor. had it any upon the westerly side at that time. All of the light which this part of the dwelling received came from the front. The only possible benefit it could receive in the way of light and air was the opening in front over the uninclosed space. It is evident that it did not re
