Read Islington’s reason for refusing this garden office and you would picture something enormous.
“Excessive scale, footprint, massing and bulk,” said the decision notice: an “inappropriate” and “discordant” addition that would be readily visible across neighbouring gardens.
The building it described stood at the bottom of a long rear garden. It was two and a half metres tall at its highest point, tucked behind the fences and intended as a home office for the occupier of the ground-floor flat.
The property is in a three-storey Victorian terrace on Brecknock Road, built in yellow stock brick and divided into flats decades ago. Behind it runs a long, narrow garden.
The owner had begun working from home several days a week and built a small office at the far end: L-shaped, 2.1 metres high at the eaves and 2.5 metres at the ridge, with a footprint of around 18 square metres. The brick was chosen to match the main building.
Because the garden belonged to a flat, the usual householder permitted-development rights did not apply. Full planning permission was required, and Islington refused it.
Why Islington refused it
The council’s only objection concerned character and appearance, and it threw a good deal of language at the building.
The office was, it said, excessive in scale, footprint, massing and bulk. Its solid brick construction made it a dominant and discordant addition to the garden.
Underneath the adjectives sat one real objection. Islington’s Urban Design Guide says that garden buildings should normally be lightweight in construction, and brick is not.
A garden office, though, is not necessarily a garden shed. If it is to be used throughout an English winter, it needs some solidity. Brick was a reasonable choice, particularly brick selected to match the Victorian building it belonged to.
The design guide expresses a preference for lightweight materials. It does not say that every brick garden building must be refused. The question was whether the choice of brick made this particular office appear dominant or out of keeping.
Why the inspector disagreed
On scale, the measurements did the arguing.
At two and a half metres to the top of its gently sloping roof, the office was no higher than the boundary fences in places. Its L-shaped plan stepped part of the building back and turned its longer elevations away from the principal views.
From the flats, it appeared as a low structure at the far end of a long garden. It could not be seen from the street.
The boundary treatments screened much of the building from neighbouring properties. Its single-storey height and position behind the fences also meant that it caused no unacceptable overlooking or loss of privacy.
The rear townscape already contained extensions and garden buildings of different shapes, sizes and materials. In that context, an 18-square-metre office in matching brick did not appear dominant or discordant.
The inspector found that it sat comfortably within its surroundings and remained appropriately secondary to the main building. Although the brick departed from the design guide’s preference for lightweight construction, it caused no material harm in this particular case.
The other concerns raised along the way did not alter the conclusion. There was no evidence that the office would become a separate home. Any alleged damage to a neighbour’s tree was a civil matter, not a reason to refuse planning permission. A single-storey building behind a boundary fence caused no unacceptable loss of privacy.
The appeal was allowed, subject to planning conditions.
What this decision means
Islington’s detailed design guidance matters, but it sets out what the council normally expects to see. It does not make every departure unacceptable.
The preference for lightweight materials is intended to stop garden buildings from appearing dominant or overly permanent. Where a brick outbuilding remains low, screened and secondary to the main property, the material alone may not produce that harm.
Planning decisions must turn on the effect of the actual building, not simply whether it ticks every box in a design guide.
