Factual and Procedural Background
This appeal arises from an order dated 22 March 1999 by Judge Bartlett QC, remitting to the Secretary of State for the Environment, Transport and the Regions a decision dated 26 May 1998. That decision dismissed an appeal against a listed building enforcement notice issued by Harrow London Borough Council on 2 September 1996. The notice concerned the removal of timber-framed windows and their replacement with white plastic double-glazed windows at a stable block within the curtilage of a Grade II* listed building known as the Grimsdyke Hotel.
The enforcement notice required removal of the unauthorised windows and reinstatement of traditional ones within six months. The principal legal issue was the meaning of "curtilage" in relation to the listed building and whether the stable block fell within it.
The lessee of the property, Company A, appealed to the Secretary of State on multiple grounds, but only the ground concerning curtilage was relevant. The appeal was considered by an Inspector who visited the site and recommended dismissal of the appeal, with an extended compliance period. The Secretary of State accepted this recommendation and dismissed the appeal.
Company A then appealed on a point of law to the High Court, which allowed the appeal, finding an error in law regarding the concept of curtilage. The Secretary of State subsequently appealed this decision to the current court. The local planning authority was served but did not participate in either appeal.
The property known as Grimsdyke is a former English country house designed by a noted Victorian architect, now operating as a hotel with extensive grounds including the stable block approximately 200 meters from the main building. The stable block is not separately listed, making the determination of its curtilage status critical.
Legal Issues Presented
- Whether the Secretary of State erred in law by failing to apply the principle that the curtilage of a listed building is confined to a small area around the building when determining if the stable block was within the curtilage of the Grimsdyke Hotel.
- Whether Planning Policy Guidance 15 (PPG 15) is incomplete for not explicitly referencing the concept of smallness in defining curtilage.
Arguments of the Parties
Appellant's Arguments
- The Secretary of State erred in law by not considering that curtilage is inherently limited to a small area surrounding the principal building.
- PPG 15 is incomplete because it fails to mention this principle of smallness when defining curtilage.
- Relied heavily on the authority of Dyer v Dorset County Council to support this view.
Appellee's Arguments
- The decision of the Secretary of State and the Inspector was legally sound and consistent with relevant case law.
- Two authorities not considered in Dyer—Calderdale BC and Debenhams v Westminster City Council—support a broader understanding of curtilage beyond a narrowly defined small area.
- PPG 15 adequately covers the relevant criteria for determining curtilage and is not incomplete.
Table of Precedents Cited
| Precedent |
Rule or Principle Cited For |
Application by the Court |
| Dyer v Dorset County Council [1989] 1 QB 346 |
Curtilage involves a "small area" around a building; an error of law if substantial physical separation is ignored. |
The court found the force of this authority was overstated by the deputy judge and that the concept of smallness is relative and not an absolute limitation in curtilage determinations. |
| Methuen-Campbell v Walters [1979] 1 QB 525 |
Definition of "appurtenances" restricted to curtilage; integral association required for curtilage. |
Provided some assistance on the factual and functional aspects of curtilage, emphasizing intimate association between land and building. |
| A-G (on the relation of Sutcliffe) v Calderdale BC (1982) 46 P&CR 399 |
Factors to determine curtilage: physical layout, ownership, and use/function; ancillary buildings may be within curtilage even if some distance away. |
Supported a broader view of curtilage including ancillary structures, influencing the court's rejection of a strict smallness principle. |
| Debenhams v Westminster City Council [1987] AC 396 |
Ancillary structures within curtilage; principal and accessory relationship required. |
Confirmed that a separate building could be within curtilage if ancillary, supporting a flexible approach to curtilage beyond immediate proximity. |
Court's Reasoning and Analysis
The court analysed the statutory framework under the Planning (Listed Buildings and Conservation Areas) Act 1990, focusing on the definition of a "listed building" which includes structures within its curtilage that have been part of the land since before 1 July 1948. The enforcement notice concerned unauthorised alterations to windows on a stable block that was not separately listed but alleged to be within the curtilage of the main listed building.
The court examined the factual matrix, including the physical layout of the property, historical ownership, and functional relationship between the stable block and the main building. The Inspector had concluded that the stable block lay within the curtilage based on these factors.
The deputy judge had allowed the appeal on the basis that the Secretary of State erred by not applying the principle that curtilage must be a small area around the building, relying primarily on Dyer v Dorset County Council. However, the court found that this reliance was misplaced because Dyer concerned different legislation and did not consider other relevant authorities that support a broader, more flexible approach.
The court emphasised that curtilage is a question of fact and degree, involving multiple considerations such as physical layout, ownership, and function, and that the concept of smallness is relative and not a definitive legal limitation. The court found no error in law in the Secretary of State's decision and concluded that PPG 15 is not incomplete for omitting explicit reference to smallness.
Holding and Implications
The court ALLOWED the Secretary of State's appeal, overturning the High Court's decision.
The holding confirms that the concept of curtilage in the context of listed buildings is not strictly confined to a small area immediately surrounding the principal building, but is a relative concept depending on factual circumstances including physical layout, ownership, and function. The decision upholds the Secretary of State's interpretation and the Inspector's findings that the stable block is within the curtilage of the listed building.
This decision clarifies that PPG 15's criteria for curtilage are sufficient and that no additional principle of inherent smallness is required. The ruling directly affects the parties by reinstating the enforcement notice and requiring compliance but does not establish new precedent beyond affirming the flexible approach to curtilage.
