Glazing and lantern-roof spec
How much brickwork versus glass
Groundwork and any building regulations work
These are why two quotes for the same job can differ, and the only way to know your price is to get prices from local firms (through Bark; we may earn a fee, at no extra cost to you).

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. Side orangeries in a conservation area, 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 anything the building regulations cover must be approved by building control or self-certified by a registered installer.
Does an orangery need building regulations approval?
Not if building control accepts it as an exempt conservatory. In England, the Class 7 exemption in Schedule 2 to the Building Regulations 2010 covers a ground-level conservatory of no more than 30 m² whose glazing meets Part K, and it must stay separated from the house by external quality walls, doors or windows, with the house's heating kept out. Knock it through or extend the heating into it and it needs approval as an extension, where glazing beyond 25% of the new floor area, plus any openings it covers, has to be offset elsewhere. A new structural opening into the house needs approval either way.
