The only question in this case is whether the certificate properly described the lot of land on which the lien is claimed. When Collapy entered into the contract with the respondent Clara E. Patch, to build for her a double dwelling-house, she had contracted with another person to remove a barn to the rear portion of her lot and build it into a dwelling-house; and subsequently, when the petitioner made his contract with Collapy to furnish labor and materials in the erection of the double house, the barn had been placed on the rear of the lot, and the work of turning it into a dwelling-house was going on. Afterwards, the respondent Patch conveyed an undivided half of a portion of the lot, which did not include the part on which the barn stood, but did include that on which was the double house.
The petitioner’s certificate described the lot as it was when the contract was made between him and Collapy, under which his lien arose, and as it is described in his petition. Under the statute he has a lien on the building and the lot of land on which it stands. As soon as his contract was made, he acquired a right to have a lien, not only on the building, but on the lot on which, by the terms of his contract, the building was to be erected. That was the whole of the lot on a part of which the barn stood. There had then been no division of it, and there was nothing to indicate that a division was contemplated, much less to show how a division would be made. The right to a lien attached to every part of the lot, as well that on which the barn stood as that occupied by the double house. Each of the buildings was attached to the realty, and the land and buildings went together as real estate. In this case we have no occasion to consider questions in relation to apportionment between claimants of liens for work on different buildings on the same lot; but a lien for work on either of the buildings extended to the whole lot as it was when " the contract was made, including everything which belonged to the real estate.
