Opinion by
Judge Williams, Je.,Isaac and Lavina Beiler (Beilers) have appealed from an adjudication and final decree directing the appellants to remove a calf barn they had constructed *214on their land, in Salisbury Township, Lancaster County.
The Beilers ’ parcel of land consists of slightly over one acre, and is located in a district that is zoned by the Salisbury Township Zoning Ordinance (Zoning Ordinance) as Rural-Agricultural (RA). On the appellants’ parcel are a large dwelling house, ,a small bam, and a small garage, all of which were erected prior to May 10,1978. On May 10, ,1978, Mr. Beiler applied for a building permit to construct an additional barn, for calves. The application was not approved by the zoning officer; because, according to his interpretation of the Zoning Ordinance, agricultural uses, including the raising of livestock, were only permitted where 'there is a minimum area of ten acres. Thereafter, on May 16,1978, Mr. Beiler contacted ¡the Township Board of Supervisors to inquire about the zoning officer’s authority to deny him a building permit.
At the direction of the Township Supervisors, the zoning officer sent a certified letter to Mr. Beiler explaining the Zoning Ordinance and the Beilers’ right to appeal to the Zoning Hearing Board. The Beilers took no appeal to the Zoning Hearing Board. Nevertheless, Mr. Beiler proceeded to construct 'the calf barn.1 Mr. Beiler was subsequently convicted of a summary offense of violating 'the Zoning Ordinance' by building the calf barn without a building permit. Thereafter, the Township brought an equity action against the Beilers to obtain a decree ordering the removal of the calf barn.
Under Section RA.02 of the Zoning Ordinance, the list of uses .permitted in .an RA district includes: “Agricultural uses related to the tilling of the land, the *215raising of farm -products, the raising and keeping of horses, -cattle, and other livestock, and the raising of poultry and poultry products.” Bams -are also permitted. Section RA.04 of the Zoning Ordinance requires a minimum area of ten acres for farms. The Zoning Ordinance defines a “farm” thus: “Any parcel of land containing ten (10) or more acres, which is used in th-e raising of agricultural products, livestock, poultry, -and dairy products. It includes -necessary farm structures within the prescribed limits and the storage -of -equipment used.”
The equity -action was heard by the trial court on March -23,1981. In construing the above provisions of the Zoning Ordinance, the chancellor determined that “farm” and “agricultural use” are -synonymous -and interchangeable terms. The chancellor then made the following additional conclusions -of -law:
1. The Zoning Ordinance at all times applied to and -controlled the -use of and buildings or structures permitted on the land of Defendants.
2. The Zoning Ordinance requires that no building -or -structure may be -erected or constructed until the zoning -officer has issued a permit for -such work where the construction is in excess of a fair market value of $1,000. Article IX, Section 902.
3. The raising -of veal calves is a farming use -and -cannot be -carried on in a Rural-Agricultural District in ¡Salisbury Township unle-s-s the property owner carrying on such use is doing so on a parcel of land of ten (10) or more -acres. Article III, ¡Section 302, 41. Farm and Article-V [.sic] RA.04a.
4. Defendants are in violation of the Zoning Ordinance because -they constructed a calf barn without securing a building permit.
*2165. Defendants are in violation of the Zoning Ordinance because they erected a .calf barn and have continuously conducted .a farming use without having the required ten (.10) acres of land.
Based on the foregoing conclusions, the chancellor entered a decree nisi ordering the removal of 'the barn. The Beilers ’ exceptions to the adjudication and decree nisi were dismissed, and the decree nisi was affirmed by final decree dated September 25,1981. The instant appeal followed.
The Beilers argue against the application of the ten-acre minimum area restriction, by asserting that their proposed use of 'the calf barn does not constitute a ‘‘farm” use, but an ‘* agricultural” use. The Beilers contend that they should be permitted to use their property for ¡agricultural purposes, and that the express restrictions imposed by the area regulations should be strictly construed so as to apply only to “farm” uses. Essentially, their position is that since the word “farm” was not used in Section RA.02 of the Zoning Ordinance, the drafters of the ordinance intended to differentiate between “farm” .use and “agricultural” use. These arguments are unavailing in the instant case.
The Beilers failed to appeal the denial of a building permit to the Zoning Hearing Board. For that reason, they are precluded from raising as defenses to the Township’s equity .action matters which .they could have raised in an appeal to the Zoning Hearing Board. See Philadelphia v. Budney, 396 Pa. 87, 151 A.2d 780 (1959); City of Scranton v. Baiderman, 74 Pa. Commonwealth Ct. 367, 460 A.2d 1199 (1983).
Lastly, the Beilers contend that the order requiring the removal of the calf barn is not the appropriate remedy for their violations of the Zoning Ordinance. We note here that the evidence clearly shows that the *217Beilers knowingly and intentionally violated the provisions of the Zoning Ordinance. Where deliberate and substantial violations of a zoning ordinance are found, it is appropriate to order removal of nonconforming ,structures. Upper Moreland Township v. Meade, 420 Pa. 613, 218 A.2d 271 (1966). We, .therefore, hold that the equitable relief granted to the Township is commensurate with the Beilers’ violations of the Zoning Ordinance.
Our scope of review 'in equity matters is limited to determining whether the trial court abused its discretion or committed ;an error of law. Borough of Trappe v. Longaker, 59 Pa. Commonwealth Ct. 572, 430 A.2d 713 (1981). After reviewing the record we find neither an abuse of discretion, nor a commission of an error of law. Accordingly, we affirm the final decree.
Obdeb
And Now, the 27th day of December, 1983, the final decree of the Court of Common Pleas of Lancaster County, dated September 25, 1981, at No. 19, Equity Docket, Page -212, is hereby affirmed.
According 'to the Beilers, they had purchased about $6,000 worth of construction materials even before applying for a building permit. The record evidence shows 'that the bam had dimensions of 60 fee't by 100 feet, and a capacity for about 200 calves.
