In speaking of the statute 14 Geo. Ill, c. 78, Gibbons says (2d ed., p. 262), that “ It did not confer any author-’ ity to one man to build half the side wall of his house on his neighbour’s land.” Cf. Traúte v. White, 46 'N. J. Eq. 437.
The early statutes in Pennsylvania likewise regulated the safety of party walls built by mutual agreement and did not authorize one owner to occupy the land of another without consent.
Section 9 of the Act of 1895 contains no' requirement as to the strength, thickness or materials' to be used in party walls,' or that the builder do anything to make the wall safe. The same is true of the earlier Act of 1872, P. L. 986. These statutes merely authorize one owner to build a wall partly upon the.land of his neighbor.
Other legislation regulates the strength and character of walls generally to be built in the City of Pittsburgh; but there is no requirement in any statute that a party wall be of a different or better construction or material than any other kind of wall. Cf. Plymouth Coal Co. v. Pennsylvania, 232 U. S. 531.
The act, as construed by the court below, is .an unreasonable exercise of the police power. No common-law right to erect a party wall partly upon another’s land, without his consent, is recognized in Pennsylvania or elsewhere. Hoffstot y. Voight, 146 Pa. St. 632; Shell v.

In England, there never has been a compulsory proceeding to erect a party wall, where no wall existed before. 19 Charles II, c. 3; 6 Anne, c. 31; 7 Anne, c. 17;
