This сase calls upon us in principal part to determine whether a district court may consider the question of non-infringement in a copyright action on a Rule 12(b)(6) motion to dismiss. We hold that, under the circumstances of this case, the district court properly determined non-infringement as a matter of law, and did not err in concluding that plaintiffs’ Amended Complaint — together with those documents incorporated therein — fails to adequately allege substantial similarity between defendants’ work and the protectible elements of plaintiffs’. We therefore affirm the judgment of the district court.
I.
The following facts are derived from the allegations set forth in plaintiffs’ Amended
*60
Complaint (“Am. Compl.”), together with those “documents attached to the complaint as an exhibit or incorporated in it by reference.”
Chambers v. Time Warner, Inc.,
In August 2004, the City of New Rochelle issued a Request for Development Proposals (“RFP”), “seeking to identify a real estate development team for the mixed-use development” of a 178-acre parcel of land at Church and Division Streets in downtown New Rochelle (“the Church Street Project”). Am. Compl. Ex. B. Plaintiff Peter F. Gaito (an architect and principal of plaintiff Peter F. Gaito Architecture, LLC d/b/a Peter F. Gaito and Associates (“Gaito Architecture”)), and defendant Josеph Simone (the president of defendant Simone Development Corporation (“SDC”)), agreed to jointly submit a proposal for the Church Street Project in response to the RFP. Id. ¶¶ 21-22. Gaito and Gaito Architecture were to design and draft architectural plans for the project, and Simone was to secure financing for the project, with the assistance of defendants Thomas Metallo and TNS Development Group Ltd. (“TNS”). Based on the parties’ agreement, plaintiffs “proceeded to draft architectural plans which included all of the design contents, concepts, zoning information and statistics regarding the proposal to be made to the City.” Id. ¶ 32.
On November 1, 2004, plaintiffs, together with defendants Simone, SDC, Metallo, and TNS, submitted a completed design proposal (in the name of SDC) to New Rochelle for its approval. Generally speaking, the proposal consisted of plans for a residential high-rise tower, retail space at the base of the tower, a new pedestrian plaza, a public park, and an aboveground parking garage. On March 11, 2005, New Rochelle awarded the Church Street Project to the group for an estimated price of $175 million. Between March and June 2005, plaintiffs prepared various schematics for the Church Street Project, and on April 5, 2005, Gaito registered plaintiffs’ designs for the project with the United States Copyright Office. Based on plaintiffs’ designs, defendant Simone Church Street LLC (of which Simone and Metallo are members) “entered into a Memorandum of Understanding with [New Rochelle] as the developer for the [Church Street] Project.” Id. ¶ 81.
In approximately June 2005, however, a dispute arose between plaintiffs and Simone and SDC concerning plaintiffs’ compensation for the project. Because of that dispute, Simone, SDC, Simone Church Street LLC, Metallo, and TNS (“the Simone Defendants”) terminated their relationship with plaintiffs, and instead retained the services of defendants SLCE Architects, LLP (“SLCE”), an architectural and planning firm, and Saecardi & Schiff, Inc., a planning firm, to continue the Church Street Project. The thrust of plaintiffs’ Amended Complaint is that the defendants thereafter unlawfully used plaintiffs’ copyrighted designs for the Church Street Project without plaintiffs’ authorization, and that SLCE developed a “re-design” for the project based in large part on plaintiffs’ designs.
The Amended Complaint identifies 35 alleged similarities between plaintiffs’ designs for the Church Street Project and SLCE’s re-design. They include similarities as to location (such as the placement of a new park, parking garage, publiс plaza, “plaza connection,” “elevator stair entry tower,” and “public landscaped open space”); similarities as to certain features and functions (such as the inclusion of a new parking garage, a “landscaped street level plaza,” “on site parking for both residential and retail use,” a water feature, public art, active retail space at the base of a residential tower, boutique shops with *61 “the flexibility for a potential single larger tenant,” “architecture that was light, airy, transparent, made of glass with hints of traditional materials,” a tower with a “slender profile,” balconies for the residential units, a parking garage with a pre-cast masonry facade, as well as certain similarities with respect to the orientation of the project); and similarities as to parameters (such as a floor-area-ratio of 5.5, a parking garage with 850 parking spaces, retail space of 44,000 square feet, and professional office space of 2,500 square feet). Id. ¶¶ 131-204. Plaintiffs’ designs and SLCE’s re-designs are attached to the Amended Complaint as Exhibits C and N.
Based on the foregoing allegations, plaintiffs commenced the instant action, alleging violations of the Copyright Act, 17 U.S.C. § 101 et seq., and asserting claims for quantum meruit and unjust enrichment under New York State law. On November 19, 2008, defendants moved to dismiss the action pursuant to Federal Rule of Civil Procedure 12(b)(6), principally arguing that, even assuming defendants had access to plaintiffs’ designs, there is no substantial similarity between the protectible elements of those designs and SLCE’s re-designs.

We review
de novo
a district court’s dismissal of a complaint for failure to state a claim upon which relief can be granted,
Maloney v. Soc. Sec. Admin.,
*62 III.
As a threshold matter, the Simone Defendants contend that this Court lacks jurisdiction to hear plaintiffs’ appeal because Peter Gaito, the holder of the copyrighted designs, did not file a proper notice of appeal, and because both plaintiffs failed to appeal from the “final decision” in this case. Neithеr argument merits extended discussion.
Broadly stated, we find no defect in either the notice or amended notice of appeal filed in this case. It is undisputed that the district court entered final judgment on May 29, 2009, plaintiff Gaito Architecture filed an original notice of appeal on June 17, 2009, and Peter Gaito, together with Gaito Architecture, filed an amended notice of appeal on June 29, 2009. Both of these notices were timely under Federal Rule of Appellate Procedure 4, because they were filed “within 30 days after the judgment or order appealed from [was] entered.” Fed. R.App. P. 4(a)(1)(A). The amended notice likewise complied with Rule 3’s requirement that a notice of appeal specify the “parties taking the appeal,” “designate the judgment, order, or part thereof being appealed,” and “name the court to which the appeal is taken.” Fed. R.App. P. 3(c)(1).
The Simone Defendants nevertheless submit that amended notices of appeal are not permitted under the Federal Rules of Appellate Procedure or under this Court’s local rules, and that Gaito’s amended notice thus should be considered a nullity. The Simone Defendants cite no authority — nor are we aware of any — that supports this propоsition, however, and nothing in the Federal Rules or our local rules forbids the filing of an amended notice of appeal within the time limits set forth by Rule 4. Indeed, the filing of a subsequent notice of appeal by a party not named in the original notice is expressly contemplated by Rule 4(a)(3), which provides that “[i]f one party timely files a notice of appeal, any other party may file a notice of appeal within 14 days after the date when the first notice was filed.... ” Fed. R.App. P. 4(a)(3). To the extent that the Simone Defendants take issue with the labeling of plaintiffs’ notice as an “Amended Notice of Appeal,” that argument is directly foreclosed by Rule 3(c)(4), which explicitly provides that “[a]n appeal must not be dismissed for informality of form or title of the notice of appeal....” Fed. R.App. P. 3(c)(4).
The Simone Defendants also argue that plaintiffs fail to appeal from the “final decision” in this case (namely, the May 29, 2009 judgment), but instead from the district court’s May 22 Opinion and Order, thus depriving us of jurisdiction to hear plaintiffs’ appeal. To be sure, plaintiffs’ amended notice of appeal indicates that they are appealing from “the May 22, 2009 ‘Opinion and Order ... entered in this Action on the 28th day of May 2009.” Rule 3(c), however, expressly provides that an appеal may be taken from an “order” of the district court. The district court’s order here disposed of all outstanding claims in this action, and that order became final upon the issuance of a final judgment on May 29, 2009. There can thus be no question that plaintiffs are appealing from a “final decision” of a United States district court, thereby satisfying the necessary predicate for invoking our jurisdiction under 28 U.S.C. § 1291.

In order to establish a claim of copyright infringement, “a plaintiff with a valid copyright must demonstrate that: (1) the defendant has actually copied the plaintiffs work; and (2) the copying is illegal because a substantial similarity exists between the defendant’s work and the protectible elements of plaintiffs.”
Hamil Am. Inc. v. GFI,
A.
At the outset, we acknowledge that “[t]he test for infringement of a copyright is of necessity vague.”
Peter Pan Fabrics, Inc. v. Martin Weiner Corp.,
The question of substantial similarity is by no means exclusively reserved for resolution by a jury, however, and we have repeatedly recognized that, in certain circumstances, it is entirely appropriate for a district court to resolve that question as a matter of law, “either because the similarity between two works concerns only non-copyrightable elements of the plaintiffs work, or because no reasonable jury, properly instructed, could find that the two works are substantially similar.”
Warner Bros. Inc. v. Am. Broad. Cos.,
These same principles hold true when a defendant raises the question of substantial similarity at the pleadings stage on a motion to dismiss. It is well settled that in ruling on such a motion, a district court may consider “the facts as asserted within the four corners of the complaint” together with “the documents attached to the complaint as exhibits, and any documents incorporated in the complaint by reference.”
McCarthy v. Dun & Bradstreet Corp.,
Thus, where, as here, the works in question are attached to a plaintiffs complaint, it is entirely appropriate for the district court to consider the similarity between those works in connection with a motion to dismiss, because the court has before it all that is necessary in order to make such an evaluation. If, in making that evaluation, the district court determines that the two works are “not substantially similar as a matter of law,”
Kregos v. A.P.,
This approach is not only consistent with our previous precedents,
see, e.g., Shipman v. R.K.O. Radio Pictures, Inc.,
Several of our sister circuits have likewise endorsed the practice of considering the question of substantial similarity on a motion to dismiss.
See, e.g., Taylor v. IBM,
No. 02-10391,
We are mindful that a motion to dismiss does not involve consideration of whether “a plaintiff will ultimately prevail” on the merits, but instead solely “whether the claimant is entitled to offer evidence” in support of his claims.
Villager Pond, Inc. v. Town of Darien,
B.
Having concluded that the district court did not err in considering the question of substantial similarity on defendants’ motion to dismiss, we now turn to whether the district court erred in resolving that question in defendants’ favor. We review
*66
that determination
de novo,
“because credibility is not at stake and all that is required is a visual comparison of the [works] — a task we may perform as well as the district court.”
Boisson v. Banian, Ltd.,
“The standard test for substantial similarity between two items is whether an ‘ordinary observer, unless he set out to detect the disparities, would be disposed to overlook them, and regard [the] aesthetic appeal as the same.’ ”
Yurman Design, Inc. v. PAJ, Inc.,
No matter which test we apply, however, we have disavowed any notion that “we are required to dissect [the works] into them separate components, and compare only those elements which are in themselves copyrightable.”
Id.
at 1003;
see Boisson,
A de novo application of these principles to the works in question here unequivocally demonstrates the utter lack of similarity between the two designs.
Plaintiffs’ overall design for the Church Street Project, for instance, consists of not one, but three prominent structures: a 34-story residential tower, a structure containing “proposed retail with residential duplex units above,” and an “8-story mixed-use building,” all oriented along Church and Division Streets in downtown New Rochelle. Defendants’ re-design, by contrast, consists of a single structure *67 comprised of a 42-story residential tower, two-story retail spaces facing Main Street, retail spacе adjacent to the tower to be occupied by two large retail tenants, and retail or commercial space adjacent to the southeastern end of the project site. While plaintiffs’ design includes a series of townhouses, the re-design contains none.
The buildings in both designs are connected by pedestrian plazas, but in different ways. Plaintiffs’ design contains a prominent plaza that connected Church and Division Streets, and that leads to the indoor parking facility and a proposed park. Defendants’ re-design instead contains a plaza that runs “along the east side of Division Street to the center of the Church/Division Lot with a through connection to Main Street.” The new park included in plaintiffs’ design sits at the corner of Leroy Place and Division Street, and features two prominent circular designs with a diagonal walkway. By contrast, the one in defendants’ redesign is a U-shaped park that wraps around the new parking garage and faces Church Street, Leroy Place, and Division Street.
Finally, and critically, it is patent that the overall visual impressions of the two designs are entirely different. Indeed, nothing in the various schematics and plans indicates any similarities between the specific aesthetic choices embodied in the respective designs.
To be sure, both designs set forth similar ideas and concepts relating to the design of a mixed-use development in downtown New Rochelle centered around a prominent residential tower. Upon examining the “total concept and feel” of the designs with “good eyes and common sense,”

In urging us to conclude that the works in question here are substantially similar, plaintiffs rely on the numerous alleged similarities between thе two designs that are set forth in the Amended Complaint. As noted above, these similarities range from the inclusion and placement of certain features in the Church Street Project to the specific parameters and specifications for the project.
In a copyright action, however, the similarity between two works must concern the expression of ideas, not the ideas themselves.
Reyher v. Children’s Television Workshop,
This Court considered the idea/expression dichotomy with respect to architectural designs in
Attia v. Society of the New York Hospital,
On appeal, we affirmed the district court’s grant of defendants’ summary judgment motion. As a preliminary matter, we emphasized that “to the extеnt that [architectural] plans include generalized notions of where to place functional elements, how to route the flow of traffic, and what methods of construction and principles of engineering to rely on, these are ‘ideas’ that may be taken and utilized by a successor without violating the copyright of the original ‘author’ or designer.” Id. at 55. While acknowledging the numerous “similarities between Plaintiffs drawings and Defendants’ architectural plans,” we concluded that “there was no infringement, because the similarities [did] not go beyond the concepts and ideas contained in Plaintiffs’ drawings.” Id. at 53. In so holding, we emphasized that upon considering the various alleged similarities between the two works, it was clear that
no more was taken than ideas and concepts. The placement of a new building, the use of truss technology to transfer weight, the alignment of floor heights and corridors, the creation of a continuous traffic loop through the hospital complex, the placement of emergency services and ambulance parking along that roadway, the location of a pedestrian area and of mechanical equipment, the arrangement of space on particular floors — these are no more than rough ideas of general nature.
Id. at 56. Thus, because plaintiffs architectural plans “consisted only of generalized ideas and concepts pertaining to the placement of elements, traffic flow, and engineering strategies,” rather than any “protected expression,” we concluded that no copyright infringement had occurred. Id. at 57.
Here, as in
Attia,
after carefully considering the various alleged similarities between plaintiffs’ design and defendants’ redesign, it is clear “that no more was taken than ideas and concepts.”
Id.
at 56. As the district court correctly observed, the various components and features that defendants allegedly misapрropriated are generalized concepts and ideas that are “common to countless other urban highrise residential developments.” District Court Opinion at 10. Indeed, were we to permit plaintiffs to seek recovery for the alleged infringement of, for instance, “architecture that was light, airy, transparent, made of glass with hints of traditional materials,” we would directly contravene the underlying goal of copyright to “en~ courage[ ] others to build freely upon the ideas and information conveyed by a work.”
Feist,
Plaintiffs seek to distinguish
Attia,
and argue that their designs do not consist of “rough ideas of general nature,”
id.
at 56, but instead of “specific expression and realization of those ideas, with the consequence that copying could constitute an infringement of copyright.”
Sparaco v. Lawler, Matusky, Skelly, Eng’rs LLP,
In short, because plaintiffs have failed to allege that “a substantial similarity exists between [defendants’] work and the protectible elements of [plaintiffs’],”
Hamil Am.,
V.
We have considered all of plaintiffs’ remaining arguments on this appeal and find them to be without merit. For all of the foregoing reasons, plaintiffs’ Amended Complaint does not “state a claim to relief that is plausible on its face.”
