This statement supports a planning application seeking the change of use of a converted barn from accommodation to a dwelling with additional use as tourism accommodation. The barn is located within the curtilage of The Old Rectory, The Cronk, Ballaugh. This proposal seeks a formal change of use from ancillary residential accommodation to a separate, independent dwelling with additional use to provide for short-term holiday accommodation use.
The barn was granted permission in 2006 (ref: 06/02206/B) for conversion to ancillary accommodation. However, it was, in practice, built as a self-contained unit, with its own kitchen, bathrooms, bedrooms, living areas, garden, access, and parking provision.
This application seeks to regularise the situation in planning terms by removing the restrictive occupancy condition, thereby allowing the unit to be occupied independently or let as short-term holiday accommodation.
This Planning Statement sets out the relevant planning history, addresses the policy context, and draws on established UK planning case law to demonstrate that the continued restriction is not reasonable or necessary in planning terms.
• 2005 Application – Ref. 05/92220/B: An application was submitted for the conversion of the barn to a separate dwelling. This was refused on policy grounds, including concerns about design and the suitability of the access. On appeal, the Planning Inspector upheld the refusal solely on design grounds, stating the proposal was contrary to Planning Circular 3/89 and draft Housing Policy 15 because the conversion failed to respect the form and character of the vernacular building. Importantly, the Inspector rejected the Highways-related refusal reason, stating that the access, though substandard, had previously been accepted and no intensification was likely to arise.
• 2006 Application – Ref. 06/02206/B: A revised application was submitted for a different scheme that retained the same principle of converting the barn, but with a design that met the character and proportions of the original building. This application was approved. Planning approval referred to the barn as “ancillary living accommodation” and imposed Condition 5, which restricted use of the barn to purposes ancillary to the Old Rectory.
Highways explicitly did not object to this application, provided that two off-street parking spaces were made available for the barn, reinforcing the point that the building was designed and assessed as a fully independent unit. The approved plans showed a two-bedroom unit with separate parking, access, and significant curtilage including garden, driveway, and a detached outbuilding.
The barn is located within the private curtilage of The Old Rectory. It has:
• Two bedrooms • Kitchen, bathroom, and living space • Its own dedicated access

• Separate off-street parking • Outdoor amenity space and a garden • A detached outbuilding suitable for garage or workshop use
Although the 2006 permission limited occupancy to "ancillary" use, the physical layout and long-term use over the last nearly 20 years clearly reflect that this is a self-contained dwelling, functionally and practically independent from The Old Rectory.
The property lies outside a designated settlement, but the principle of residential use was established under Housing Policy 15 and confirmed through the 2006 approval.
Housing Policy 15 (Strategic Plan 2016):
This policy supports the conversion of existing, traditionally styled properties in the countryside into dwellings, provided that:
• The proposals respect the proportion, form and appearance of the existing building. • The building is of traditional rural character.
This was the central policy test applied in the 2005 and 2006 applications. The 2005 scheme was refused because it failed the design test. The 2006 application was approved, confirming that the principle of conversion to residential use was acceptable under Policy 15. No further structural or external changes are proposed now; the building continues to comply with Policy 15.
General Policy 2 (Strategic Plan):
This policy sets out overarching development principles including:
• No adverse impact on neighbouring properties or the character of the area • Appropriate access, parking, drainage and infrastructure
This proposal does not introduce any new built development and maintains all existing infrastructure. The proposed use (residential or holiday accommodation) will not intensify the use of the site beyond what has been occurring for nearly two decades.
Other Material Considerations:
• The barn is not Registered, and the site is not within a conservation area. • The visibility from the access is restricted to the east due to a bend and the proximity of Old Ballaugh Church, but the road naturally narrows at this point, creating a traffic calming effect. To the west, visibility is considerably better. • Highways raised no objection to the proposed use of the access at the time of the 2006 approval and reaffirmed this position following a recent site meeting in June 2025.

5.1 The Condition Is Now Unnecessary and Unreasonable
The restriction imposed in 2006 served to limit the unit to ancillary use. However, the dwelling was constructed with all the features and functions of an independent residence. The following key points are relevant:
• The unit includes its own kitchen, bathroom, bedrooms, and living spaces. • It has separate access, parking, garden and outbuilding.
No material difference arises whether the building is occupied by relatives, tenants, tourists or an entirely unrelated household. In planning terms, the impacts are the same.
5.2 Case Law
Planning authorities often impose conditions on “granny annexes” or converted outbuildings requiring that they be used only as ancillary to the main dwelling – i.e. not occupied as separate, independent dwellings. Such conditions aim to prevent the unauthorised creation of a new dwelling (especially in areas where new housing would conflict with policy). However, case law has established important principles that sometimes render these ancillary occupancy conditions unnecessary or inappropriate – particularly when the accommodation is clearly a self-contained unit. Below we summarise key cases and decisions:
Appeal Cases Removing or Relaxing Ancillary Conditions
The following appeal decisions relate to cases where conditions restricting annexes were removed or varied because the accommodation was effectively capable of independent use without causing additional planning harm:
West Berkshire – College Farm Annexe (2011):
This appeal concerned a condition on a purpose-built annexe that restricted it to ancillary use only (preventing any separate dwelling use). The owner sought to vary the condition to allow short-term holiday lets in the annexe when it wasn’t needed by the family. In allowing the variation, the Inspector made observations very relevant to ancillary conditions in general. She noted the Council had already permitted a fully self-contained building “for residential purposes incidental to the occupation of [the main farm]” – meaning the building could already be occupied by “any number of family members or guests” without breaching the original permission.
Given that fact, the Inspector found little practical difference in impact between use by family/guests and use by unrelated short-term occupants. The annexe had its own access, parking, and all facilities, so its use for holiday accommodation was not materially different from its use as a granny flat. She concluded that the condition (which outright prohibited any independent or let use) was not “necessary” nor “reasonable” in planning terms. Citing the well-known tests from Newbury and government guidance (e.g. Circular 11/95), the Inspector removed the blanket ancillary restriction. A new condition was substituted to allow ancillary or holiday use, still with a caveat that it not be used as a separate permanent dwelling or given a separate curtilage.

In College Farm, the Inspector effectively recognised that an annexe which is entirely self-contained and physically separate is, in reality, capable of functioning as an independent unit without additional harm. If its use as part of the main household is already acceptable (and indeed indistinguishable from a small dwelling in terms of facilities and impact), then a condition preventing any other form of occupation might fail the necessity test. Importantly, the decision highlighted enforceability issues – for instance, if an annexe can lawfully host “any number of family members or guests”, how enforceable (or meaningful) is a condition that tries to distinguish an unrelated occupant? The line between a cousin “guest” and a friend staying, or even a tenant, can be blurry. Inspectors will not impose conditions that are so hard to monitor as to be ineffective. In one appeal decision, it was expressly noted that “a condition to restrict [a self-contained annexe] to ancillary use ... would not be enforceable in [the] circumstances” (acp.planninginspectorate.gov.uk). This underscores that when accommodation is clearly a separate dwelling in all but name (e.g. separate entrance, facilities, and even separate parking/garden), simply labelling it “ancillary” may be impractical in the long run.
Other Appeal Examples:
Planning appeal records contain numerous examples of applicants seeking to remove ancillary occupancy ties. Success often depends on site-specific factors like location and policy compliance. For instance, where an annexe is within a settlement or sustainable location, inspectors have allowed them to become independent dwellings because the usual objections to a new house (e.g. isolated development or inadequate access) don’t apply.
By contrast, in more remote rural areas, an inspector might find the condition still serves a planning purpose (preventing a new dwelling where one wouldn’t normally be allowed). The layout and relationship between the annexe and main house is also crucial. If an annexe is physically attached or shares key facilities/utilities, it’s easier to argue it remains part of the main dwelling. But if it is physically separate and self-contained, some inspectors have questioned the usefulness of insisting it stay ancillary. One Planning Inspector noted that even though an annexe provided all the facilities for independent day-to-day living, what mattered was whether it actually functioned as part of the same household (planninggeek.co.ukplanninggeek.co.uk). If not, the condition was likely being breached and a separate dwelling effectively created anyway.
Enforcement Cases Highlighting “Clearly Independent” Use
Enforcement appeals also shed light on when an “ancillary” use condition is deemed inappropriate or has been effectively abandoned. In Merton LBC v Secretary of State (2020), for example, an outbuilding had been built as an annexe but was found being used as an independent flat. The appellant argued it was still just an ancillary annexe, citing Uttlesford and Whitehead. The Inspector affirmed the legal principle that ancillary use within a curtilage does not require permission but on the facts he found the outbuilding “did not lend itself to a use ‘integral’ to the main house” - it had its own front door onto a different street, no internal connection, a separate doorbell, and was functionally separate. This degree of separateness meant in reality it was an independent dwelling.
The appeal was dismissed and the council’s enforcement notice upheld. The lesson here is that when an annexe is clearly being used as a self-contained unit, it will be treated as a breach of planning control (if not authorised). Put another way: if a planning condition tries to insist such a unit remain ancillary but the occupants are living completely separately, the condition isn’t truly preventing the mischief - the situation has crossed into “separate dwelling” territory regardless of what the paperwork says.

Planning Practice Commentary (England):
A widely cited planning commentary states:
“Clearly, the [units] could not remain ancillary… that use would cease as soon as [the primary dwelling] stops being occupied. The condition is vague and meaningless and fails the test of enforceability.”
In other words, once a building can operate separately, imposing a condition that it must not is contrary to good planning practice.
This reinforces the idea that in cases of clearly independent accommodation, ancillary occupancy conditions can be of limited value. They might be overridden by reality, or, as seen in College Farm, deemed unreasonable when the impacts are equivalent to permitted use.
Whilst each case turns on its facts, we submit that the trend in decisions is clear: where an annexe is for all intents and purposes an independent dwelling, an insistence that it remain “ancillary” is often held to be unreasonable.
Instead, planning authorities should either allow it as a separate dwelling (if appropriate) or, if harm would result, refuse it outright rather than rely on a nominal condition. The overall message from the case law is that planning control should reflect the reality of use - conditions should not arbitrarily constrain a self-contained unit that could operate on its own, especially when such a restriction fails the tests of necessity or enforceability.
As noted above:
• The access has operated safely for nearly 20 years as the primary entrance for the barn. • Highways accepted its use in the 2006 application and confirmed during a June 2025 site visit that they have no objection to its continued or formalised use. • The site includes two dedicated off-street parking spaces (as required under the 2006 condition and current standards). • There is no history of road safety incidents at or near the site access.
The access serves one additional unit and does not generate significant traffic. There is no intensification of use resulting from this change.
The applicant requests flexibility to use the barn either as a permanent dwelling or as a short-term holiday let. This poses no material planning difference whilst providing additional use as quality holiday accommodation. In summary, this additional use:
• Supports the Island’s rural tourism economy • Involves no additional development • Aligns with the current use of the site and building

As there is sufficient on-site parking, no shared facilitie, and separate access, the property can comfortably accommodate either use without detriment to the area.
The barn at The Old Rectory was approved under 06/02206/B as a converted dwelling compliant with Housing Policy 15. It has functioned as a self-contained residential unit ever since with all the necessary provisions and infrastructure to support an independent dwelling. There is no dependence whatsoever upon the adjacent dwelling (The Old rectory) to which it is currently conditioned as ‘ancillary to’. The continued application of an "ancillary only" condition is now:
• Unreasonable, as the building is entirely capable of separate use • Unnecessary, because there are no planning harms from its independent occupation • Unenforceable, given the self-contained nature of the unit and lack of any meaningful dependence on the main dwelling
The proposal raises no new planning issues, causes no harm and complies with the Strategic Plan policies (especially Housing Policy 15). It also aligns with UK case law and inspector conclusions that cautions against unreasonable, unnecessary or over-restrictive planning conditions.
We respectfully request the Department to grant permission for the change of use thereby allowing the barn to be used as a separate independent dwelling, with the option of short-term holiday letting.
