Esther Gurvits and Joseph Gurvits v Secretary of State for Levelling Up, Housing and Communities and London Borough of Barnet [2024] EWHC 490 (Admin)
Gurvits home office enforcement is a useful High Court authority on when a business use in domestic outbuildings becomes a separate planning use, and on how an enforcement notice interacts with existing lawful or permitted rights.
The court dismissed the owners’ section 289 appeal. The Inspector had been entitled to find that three former domestic outbuildings had become a single, more intensive commercial office and storage planning unit, and that removing the office facilities and reconnecting the buildings to lawful domestic use did not unlawfully extinguish future permitted rights.

What Gurvits decided
The case concerned linked outbuildings behind 46, 48 and 50 Hurstwood Road in north-west London. The owners had progressively built three structures and used parts of them for home working and storage before joining them together.
By 2021 the combined building contained an open-plan office, private offices, reception area, male and female toilets, a kitchenette and extensive business storage. Barnet served an enforcement notice alleging a material change of use to a commercial office with associated storage.
The Inspector dismissed the enforcement appeals and added a requirement to remove the internal doors linking the three component buildings. Mr Justice Mould dismissed the owners’ High Court appeal.
Intensity can change the character of a home-working use
Working from home is not automatically a material change of use. The planning question is whether the character of the use has changed as a matter of fact and degree.
Here the evidence showed a business employing staff, extensive filing, a reception arrangement, separate toilets and an office layout extending across the three former domestic outbuildings. The Inspector was entitled to regard that as materially different from incidental home working.
The planning unit was central
The three houses remained separate dwellings. The Inspector found that the amalgamated rear building had become a distinct planning unit used for the office and storage business.
The High Court held that this conclusion was properly open to him. The familiar planning-unit principles remain an exercise of fact and degree, and a physically recognisable area can become a separate unit where its use is substantially different from the surrounding land.
Class E outbuilding rights did not answer the later use question
Each component structure had originally been erected in reliance on the householder Class E permitted development right for buildings required for purposes incidental to a dwellinghouse.
That did not mean the later combined commercial use remained incidental. The Inspector was entitled to consider the original domestic purpose of the structures when assessing whether the later office use had changed character.
The case therefore illustrates the distinction between permission for the physical building and the separate planning question of how that building is used.
The enforcement notice could remove works integral to the breach
The Inspector upheld requirements to remove the commercial kitchen facilities and toilets. Those works had been installed as part and parcel of the unauthorised office use and could properly be removed to remedy the breach.
He also added a requirement to remove the internal connecting doors and seal the openings, returning the single office building to three separate outbuildings capable of domestic incidental use.
The Mansi principle protects future lawful rights
The owners argued that requiring permanent removal of toilets and kitchen facilities would unlawfully take away their future rights to use or alter the outbuildings lawfully.
The court rejected that argument. Under the Mansi and Duguid line of authority, an enforcement notice is construed so that existing lawful and permitted rights survive. It was not necessary to rewrite the notice expressly to repeat statutory rights which already operated as a matter of law.
That means the notice could require removal of facilities installed as part of the unlawful commercial use without permanently preventing future lawful domestic works.
Why Gurvits matters in practice
The case is particularly useful where a home business has grown gradually. Historic domestic use of an outbuilding does not immunise a later, more intensive business use if its character and planning unit have materially changed.
It is also a useful companion to the wider enforcement case law on remedial steps. See Planning Geek’s guide to planning enforcement notices.
