Opinion by
Mr. Justice Dean,At the first hearing in this case, both in oral argument and on the paper-books, the case turned on but a single question, viz, whether the restriction as to building placed by the original grantor on lot No. 1208, in favor of lots 1206 and 1210, was *24perpetual, or whether it ended with the existence of the house then upon the middle lot. After a careful consideration, we decided the restriction was continuing, and directed that an injunction issue in conformity to the prayer of the petitioner. The effect of this was to restrain defendants from putting any building on 1208 to the rear of the house upon it in 1832 higher than ten feet from the surface of the lot.
The defendants then petitioned the court for a modification of the decree, for the reason, that even if the judgment of the court that the restriction was a continuing one were well founded, the plaintiffs, by their own acts, had relinquished the-right to assert it to the full extent set out in Hause’s deed of 1832. The case is fully reported: Landell et al. v. Hamilton et al., 175 Pa. 327.
The court ordered a reargument only on the question as to-whether the decree should be modified, and if so, to what extent. This reargument was heard on the 27th of May, 1896.
As will be noticed in the reported case, Landell’s lot is 1206,. the eastern one; the defendant’s, 1208, .the middle one; and Allen’s, 1210, the western one. It now appears, on reargument, that as to Landell’s lot, either he or his grantors, years prior to the filing of the bill to restrain defendants, had built a solid wall,, seventeen feet high, from tíre rear of the old building on 1208-south towards Sansom street, a distance of not quite nineteen feet, and then continued the same kind of wall at the height of twelve feet, thirty-seven feet further. The defendant calls this a party wall; there is no evidence that it is such, or was so intended by the builder, except that it extends over the line of 1206 and rests partly on 1208. The character of the structure, twelve feet in height for thirty-seven feet in length, and then seventeen feet high for about nineteen feet, rebuts the inference that it was ever intended as a party wall in the legal signification of that term, to be used by both lot owners for building-purposes. The most that can be said for it on the evidence is. that it was a partition or division wall, the same as a partition fence dividing the two lots. It may have been a trespass on 1208 to the extent it rests on that lot; if so, the owner or owners submitted to it; but by their submission they acquired no-right inconsistent with the restriction imposed upon the middle-lot by the covenant in the deed. The right to a party wall is *25statutory. It is not a right to at any time and in any manner use the land of another. One of two adjoining owners, for building purposes, may, subject to limitations consistent with the right of each, encroach upon his neighbor with a party wall. But, manifestly, this was no such structure, and conferred on defendants' no right to assume it absolutely terminated the restriction in favor of the Landell lot. For even if a party wall, at most it gave the middle lot owner the right to use it as a party wall to the height of ten feet, the limit of the restriction.
But the wall was solid to the height and length it was built. The purpose of the, restriction was to afford light and air to-1206, and the extent of the enjoyment was measured by the extent of the restriction on 1208. That restriction was, no-building or part of a building should be added to the house upon the lot to the rear higher than ten feet from the surface of the lot. But Landell or his grantors themselves erect a solid wall along the line of 1206 and 1208, fifty-six feet in length from the rear of the old building on the middle lot, through which neither light nor air could penetrate. By their own act plaintiffs have said, for nineteen feet we do not ask for light and air, except at the height of seventeen feet, and for thirty-seven feet further we do not ask for either, except at the height of twelve feet. Clearly equity will not compel defendants to-award to plaintiffs that which by their own distinct and unequivocal act they have declared is valueless to them.
It is alleged now the ownership of plaintiff to 1206 does not extend to Sansom street, but only one hundred and forty-nine feet from Chestnut, leaving about eighty-six feet to which the injunction should not apply. To tins it is replied, the bill alleges and the answer admits, plaintiffs, Landell et al., own back to Sansom street, and there is no proof to the contrary. So-far as we can discover from the pleadings and proofs the title of Landell et al., or any part of it, is nowhere disputed; therefore we can make no modification of the decree in this particular.
The restriction here, by the covenants in the original deeds,, renders it impossible to make such modification of the original decree as will preserve the apparent right of defendant a» against each of these parties. The middle lot is servient to both the eastern and western; but the owner of neither the *26eastern nor western can, by his independent act or deed, relinquish that suhservienoy so as to affect the other. Here the owner of 1206 has declared that for nineteen feet light and air from 1208 are valueless to him below a height of seventeen feet, and for thirty-seven feet further they are valueless below twelve feet; thus, for a distance of fifty-six feet waiving the strict terms of the restriction. The owner of 1210 has also waived the restriction by building his wall fifty-six feet to a height of thirteen feet nine inches. We cannot say, because the one waived the restriction for nineteen feet to the height of seventeen feet, therefore the other did so too; or because one waived it for thirty-seven feet to the height of thirteen feet nine inches, therefore the other is bound, when by his own act he only waived to a height of twelve feet for that distance. As we have said, neither could, by his independent act or deed, affect the right of the other. But it seems to us the correct conclusion is that, to the full extent they have equally gone in dispensing with the restriction, both can in equity be made subject to our decree.
Therefore, we modify the original decree so that it shall not operate to restrain defendants from building to a height of thirteen feet nine inches, for a distance of nineteen feet from the rear of the old main building of the middle lot. Further, from the end of the nineteen feet thus specified it shall not operate to restrain defendants from building to a height of twelve feet from the ground for a further distance of thirty-seven feet.
The costs of this case to be taxed as part of the original decree.
