The plaintiffs, Grey Rocks Land Trust (Grey Rocks), and its trustees, P. Andrews McLane and Douglas McLane, appeal the Superior Court’s (Smith, J.) order upholding the decision of the defendant, Town of Hebron Zoning Board of Adjustment (ZBA), to grant a variance to co-defendant, William Robertie, doing business as the Newfound Lake Marina, Inc. (Marina). Because Robertie failed to sustain his burden of proving that he would suffer a hardship if the variance were denied, we reverse.
The Marina is a pre-existing, nonconforming use located in the Lake District established by the Hebron Zoning Ordinance, near the mouth of the Cockermouth River, which flows into Newfound Lake. The purposes of the Lake District are “to limit the uses of this district so as to protect [scenic, recreational and environmental] values and encourage only such further developments as will not harm the environment or destroy this district or any part thereof as a natural and scenic resource of the Town.” HEBRON ZONING ORDINANCE, Art. VI, A. Permitted uses in the Lake District include small hotels and motels, restaurants, small office buildings and up to four-unit multiple-family dwellings. Id. Art. VI, B. The Marina pre-existed the enactment of the ordinance and is, therefore, permitted as a nonconforming use.
Grey Rocks is a land trust that owns property abutting the Marina. The trustees and beneficiaries use the trust property for recreational and residential purposes.
The Marina’s facilities are located on a tract of roughly 35 acres on both sides of a channel, most of which is wetlands and/or flood plain. At the time of Robertie’s application for a variance, the Marina’s facilities consisted of five buildings: three buildings used for boat storage, one building used as a boat repair shop, and one building used for retail sales and rentals. These buildings are clustered close to the town road that services the Marina, away from the channel, and buffered from Grey Rocks’ property. The Marina also includes docks and “bank slips” in the channel near the mouth of the river sufficient to accommodate at least 111 boats.
In October 1987, Robertie applied to the Hebron Board of Selectmen for a permit to build an additional boat storage building. The selectmen denied the application because it was an expansion of a nonconforming commercial use under the zoning ordinance.
In August 1988, Robertie applied to the ZBA for a variance to build the boat storage building. On September 14, 1988, the ZBA held a hearing to consider the application, which trustee Douglas McLane attended on behalf of Grey Rocks. The minutes from that *242meeting reflect that trustee McLane “thinks this doesn’t meet the requirements of Zoning[,]” but that “[h]e realizes it takes many boats for a business.” At the conclusion of the hearing, the ZBA voted unanimously to grant the variance, and on October 5,1988, the ZBA voted to deny Grey Rocks’ appeal for a rehearing.
Grey Rocks appealed to the superior court pursuant to RSA 677:4. The Court (Smith, J.) remanded to the ZBA “for further hearing, if necessary, to make specific factual findings on the required grounds for a variance.”
The ZBA held a public meeting on December 27, 1990, but voted against holding further hearings. The ZBA remitted a set of factual findings to the court, in which it essentially reaffirmed its previous findings. The court then dismissed the plaintiffs’ appeal, ruling that “[t]he Board’s decision amounted to an implicit finding that the several requisites for a variance had been met.”
On appeal, the plaintiffs argue that the trial court erred in ruling that the ZBA’s decision was reasonable and legally correct, because the ZBA made no factual findings relating to hardship, and no supporting facts appear in the record. We agree.
The superior court correctly set out the requirements for a variance:
“To obtain a variance under RSA 674:33[,] 1(b), an applicant must satisfy each of five requirements: (1) that a denial of the variance would result in unnecessary hardship to the applicant; (2) that no diminution in value of surrounding properties would occur; (3) that the proposed use would not be contrary to the spirit of the ordinance; (4) that granting the variance would benefit the public interest; and (5) that granting the variance would do substantial justice.”
Rowe v. Town of North Hampton, 131 N.H. 424, 427, 553 A.2d 1331, 1333 (1989); Gelinas v. Portsmouth, 97 N.H. 248, 250, 85 A.2d 896, 898 (1952).
This court has further defined the requirement that a denial of a variance result in unnecessary hardship. The standard for establishing hardship is narrow. Governor’s Island Club v. Town of Gilford, 124 N.H. 126, 130, 467 A.2d 246, 248 (1983). “For hardship to exist under our test, the deprivation resulting from application of the ordinance must be so great as to effectively prevent the owner from making any reasonable use of the land.” Id. (emphasis added). Furthermore, the hardship must arise from “some unique condition of *243the parcel of land distinguishing it from others in the area . . . Crossley v. Town of Pelham, 133 N.H. 215, 216, 578 A.2d 319, 320 (1990) (emphasis added). “The uniqueness of the land, not the plight of the owner, determines whether a hardship exists.” Rowe, supra at 428, 553 A.2d at 1334.
In this case, the plaintiffs have met their burden of proving that the ZBA’s decision was “erroneous as a matter of law or unreasonable on a ‘balance of probabilities.’” Crossley, supra at 216, 578 A.2d at 320 (quoting RSA 677:6). Defendant Robertie demonstrates a misunderstanding of the relevant law when he states jn his brief that “[Grey Rocks] is substantially to blame for the inadequacy of the local record, because their representative failed to introduce sufficient evidence to indicate the lack of the elements for a variance . . . .” This is directly contrary to the law. The„party seeking a variance, in this case Robertie, bears the burden of establishing each of the requirements for a variance. Rowe, supra at 427, 553 A.2d at 1333.
Although “the failure to disclose specific findings is not error where ... no request for such findings is made,” Barrington East Owners’ Assoc. v. Town of Barrington, 121 N.H. 627, 630, 433 A.2d 1266, 1268 (1981), “[t]here must, however, be sufficient evidence before the board to support a favorable finding on each of the statutory requirements for a special exception,” id. We have examined the minutes of the four ZBA meetings at which the Marina variance was discussed, including the December 27, 1990, meeting at which the ZBA responded to the superior court’s request for specific factual findings. The only reference to a unique hardship is the conclusory statement in the minutes of the October 5, 1988 meeting that “[t]he Bd. feels a hardship does exist unique to this property which distinguishes it from all others similarly situated.” The minutes fail to reveal the facts upon which this legal conclusion is based.
In order for the ZBA to have concluded that a hardship exists, it would have to have found that literal enforcement of the ordinance bars any reasonable use of the land. Crossley, supra at 216, 578 A.2d at 320. Thus, a showing that Robertie was making a reasonable use of the land at the time of the application for a variance would preclude a finding of hardship.
The uncontroverted fact that the Marina had been operating as a viable commercial entity for several years prior to the variance application is conclusive evidence that a hardship does not exist. The *244defendant Robertie was clearly making a reasonable use of his property prior to his application for a variance. A viable, nonconforming business fails to meet the strict standard for a finding of hardship established by cases such as Governor’s Island supra.
In addition to failing to find that denying the variance would preclude any reasonable use of Robertie’s property, the ZBA also failed to find that Robertie’s land was unique. The ZBA stated in its submission of fact findings to the court that “[t]he Newfound Lake Marina is the only Marina located within the Town of Hebron.” A nonconforming use, however, may not form the basis for a finding of uniqueness to satisfy the hardship test. The nonconforming use that is presently located on Robertie’s land has nothing to do with the land itself. Therefore, because the record fails to reflect any other basis for finding that Robertie’s land is unique, we hold that the ZBA erred as a matter of law in finding that Robertie satisfied the uniqueness prong of the hardship requirement.
The defendants next argue that, independent of the hardship requirement, the owner of a nonconforming use has a right to “[develop the] nonconforming use in a way that results in a mere intensification of the use that reflects a natural expansion and growth of trade.” Town of Hampton v. Brust, 122 N.H. 463, 469, 446 A.2d 458, 461 (1982). On the other hand, “enlargement or expansion may not be substantial....” New London Land Use Assoc. v. New London Zoning Board, 130 N.H. 510, 516, 543 A.2d 1385, 1388 (1988).
“[I]n order to determine how much a nonconforming use may be expanded or changed, we must look to the facts existing when the nonconforming use was created. We must also consider the extent to which the challenged use reflects the nature and purpose of the prevailing nonconforming use, whether the challenged use is merely a different manner of using the original nonconforming use or whether it constitutes a different use, and whether the challenged use -will have a substantially different impact upon the neighborhood.”
Id. at 517, 543 A.2d at 1388 (citations omitted).
We have never permitted an expansion of a nonconforming use that involved more than the internal expansion of a business within a pre-existing structure. U-Haul Co. of N.H. & Vt., Inc. v. City of Concord, 122 N.H. 910, 451 A.2d 1315 (1982) (construction of residential apartment within commercial building); Brust supra (expansion of arcade business by adding more machines within existing structure). *245Moreover, the two examples we gave in Brust to illustrate the kind of expansion that is permissible both involved internal expansion within an existing building. Brust, supra at 469, 446 A.2d at 461 (law firm could increase number of lawyers or clients; restaurant could add more tables and chairs).
Furthermore, in U-Haul no abutters objected to U-Haul’s renovation, and the court found that the proposed apartment “would have less of an impact on the area than a permissible [use].” U-Haul, supra at 912-13, 451 A.2d at 1317.
In the instant case, it is apparent from the aerial photographs, and the defendants concede in their brief, that the new building is located 450 feet closer to Grey Rocks than the five pre-existing buildings. Thus, the new building clearly has a greater aesthetic impact on the abutting property than the other five buildings. In this case, unlike in U-Haul and in Brust, we hold that the new building will have “a substantially different impact upon the neighborhood.” New London, supra at 517, 543 A.2d at 1388.
Any expansion of a nonconforming use must be evaluated in the context of the zone in which it is located. Cf. Levesque v. Hudson, 106 N.H. 470, 214 A.2d 553 (1965) (variance for construction of bank granted where district was already largely commercial), overruled on other grounds by Winslow v. Holderness Planning Board, 125 N.H. 262, 269, 480 A.2d 114, 117 (1984). The Lake District is intended to protect “scenic, recreational and environmental values” and to “encourage only such further development as will not harm the environment or destroy this district or any part thereof as a natural and scenic resource of the Town.” We hold as a matter of law that the construction of a new building, such as the one proposed by the Marina, would substantially impair the natural scenic, recreational and environmental values of the surrounding property, contrary to the purposes of the Lake District, and is therefore beyond the scope of the “natural expansion,” Brust, supra at 469, 446 A.2d at 461, to which the Marina is entitled.
The decision of the ZBA granting a variance to defendant Robertie is reversed.
Reversed.
