Common questions
How much does an orangery cost?
An orangery costs roughly £15,000 to £60,000 installed in the UK, typically around £25,000. A small orangery up to about 12 square metres is £15,000 to £25,000, a medium one £25,000 to £40,000, and a large or high-spec build £40,000 to £60,000. A lantern roof upgrade and bi-fold or French doors each add a few thousand more.
Is an orangery cheaper than an extension?
Usually yes. An orangery at £15,000 to £60,000 tends to undercut a full single-storey extension of similar size, because it uses a lighter frame and glazing rather than solid walls and a tiled roof throughout. It gives a light, room-like space for less, though a full extension is better insulated and usually adds more value. See our conservatory and extension guides for the comparison.
Do I need planning permission for an orangery?
Often not: many orangeries fall under permitted development, like conservatories, provided they are within the size and height limits and not forward of the front of the house. Conservation areas, listed buildings and larger builds are the exceptions. Building regulations may apply depending on how it connects to the house, so check both before ordering.
How much value does an orangery add to a house?
There is no honest single figure for this, and any percentage you are quoted is a guess dressed up as data. What is knowable is the arithmetic: an orangery adds permanent ground-floor area, and floor area is what a valuer measures. A medium orangery of 12 to 20 m² costs £25,000 to £40,000 here, so roughly £1,250 to £3,300 per square metre of new space, which is worth comparing against what houses actually sell for per square metre in your area. It tends to stack up where a shortage of ground-floor space was the thing holding the house back, it is never guaranteed, and it is safest treated as space you will enjoy rather than an investment.
What is the difference between an orangery and a conservatory?
A conservatory is mostly glass with a glazed or solid roof, while an orangery has more brickwork, a flat roof with a central glass lantern, and often internal pillars, so it feels more like a solid room. That extra structure is why an orangery costs more than a conservatory but stays usable in more of the year.
Can I build an orangery myself?
Realistically no. An orangery involves foundations, a brick base, a glazed roof and often electrics and heating, so it is a multi-trade build, not a weekend project. That is why prices run £15,000 to £60,000 installed. You might project-manage and do finishing touches, but the structure, glazing and any wiring need trades to get it watertight and signed off.
Does an orangery add value to a house?
It can, but rarely the full outlay. Spending £15,000 to £60,000 adds usable living space that helps a sale, yet most buyers value it below what you paid. It pays back better than a cheap conservatory because it feels part of the house. Build it mainly to enjoy the room while you live there, not purely as an investment.
