Two rooms that look alike, and are treated differently.
Conservatory and orangery planning permission in Jersey.
A conservatory of 30 square metres or less often needs no planning permission in Jersey, and a small one may not need building bye-law permission either. An orangery is measured against the same planning limits, but it is a different story at bye-law stage: with a mainly solid roof, Jersey does not count it as a conservatory at all. We tell you which rules your design falls under, then draw it and take it through.

How It Works
Size and roof first
We measure the proposal against the 30 m² and height limits, and check whether the roof counts as translucent. That decides which permissions you need before anything is drawn.
Application
Where planning permission is needed, we produce the drawings and submit. Where it is not, we say so and go straight to the construction drawings.
Bylaw Plus
Construction drawings for the base, the roof structure, the glazing and the doors between the new room and the house, so your builder can price it and start.
Planning Note
Jersey defines a conservatory by its glazing: at least 75% of the roof and 50% of the external walls must be translucent. Meet that and the conservatory exemptions apply. Most orangeries — solid roof, a central lantern, brick or stone piers — fall short of it, so for bye-law purposes they are an extension. The planning limits below apply to conservatories and extensions alike. If the house is listed or in a conservation area, check before assuming any of them applies to you.
You will not need planning permission if all of these apply:
- Your permitted development rights were not removed by a condition on an earlier permission
- The floor area is no more than 30 square metres in total
- With a pitched roof, it is no more than 3.5 metres high overall, and the bottom of the roof slopes is no more than 2.5 metres above ground
- With a flat roof, it is no more than 3 metres high
- Any part within 1 metre of a neighbouring boundary is no more than 2 metres high

House Extensions we have taken through planning
Glass Veranda Addition
“Added a glass veranda to the rear of our granite cottage. The design balanced old character with modern materials, which the planning officers really liked.”
Insulated Sunroom
“Replaced an old conservatory with an insulated sunroom. The drawings were clear, accurate, and submitted online with zero hassle.”
Rear Kitchen Extension
“We needed extra space for the family but were worried about overshadowing the plot next door. The drawings were spot on and tackled the privacy issues before the planning officers even had a chance to raise an objection.”
