What a lantern roof actually does
An orangery is a hybrid: somewhere between a conservatory and a single-storey extension. Brick or rendered piers around the perimeter, a flat perimeter roof, and a glazed lantern in the centre that pulls daylight down into the heart of the room. That central lantern is the defining feature, and it changes how the room feels in a way that’s hard to grasp until you stand inside one.
If an orangery’s been on your mind, our orangeries page is the natural starting point. It covers the variations we fit most often across Staffordshire and Cheshire.
Compared to a standard conservatory roof, a lantern brings light from above without committing the whole roof to glass. The perimeter flat roof gives you a proper ceiling line, room for downlighters and AV, and meaningful insulation, so the orangery feels like part of the house rather than a glazed pod stuck on the back.
Our wider conservatories range is the place to compare orangery and conservatory side by side for your home.

Why proportions matter more than size
Get the proportions right and a modest orangery feels generous. Get them wrong and even a large one feels squat. The lantern needs to be sized in relation to the room beneath it: too small and it looks like an afterthought; too large and it dominates the elevation from the garden. As a rough starting point, the lantern is typically around 50-60% of the orangery’s footprint, with the perimeter roof making up the rest.
Ceiling height inside matters too. A standard orangery internal ceiling sits at around 2.4m to the underside of the lantern frame, with the lantern itself adding another 600-900mm above that. The result is a generous, airy space that genuinely feels different to a conservatory of the same footprint.
Light, glare and the West Midlands climate
A lantern brings in light from above, which is qualitatively different to light coming in horizontally through walls. It bounces off the perimeter ceiling and fills the space evenly. That’s the upside. The downside, if you don’t plan for it, is glare and solar gain in summer.
Modern lantern glass specifications handle most of this. Solar-control coatings reflect a meaningful percentage of summer heat back out, and self-cleaning coatings reduce the maintenance burden on hard-to-reach glass. For a south or west-facing orangery in Stoke, Stafford or Crewe, solar-control glass is rarely something we’d talk a customer out of. The Energy Saving Trust’s overview of glazing is a useful read on how solar gain and U-values balance out in a domestic setting.
Doors and how the orangery connects to the garden
The choice of garden-facing doors changes how the orangery is used. A pair of French doors suits a more traditional orangery on a Victorian or Edwardian home — they sit comfortably between the piers and give a defined threshold. Bifolds or sliders work better on contemporary builds where the design is leaning more towards open-plan living.
Door specifications matter as much as the orangery structure itself. Multi-point locking, anti-snap cylinders and quality weather seals are the basics. The independent BFRC energy rating on glass units lets you compare like-for-like across suppliers.
Planning permission and Building Regulations
Many orangeries fall under permitted development and don’t require planning permission, but the rules tip on things like total volume added, height of the eaves and proximity to boundaries. Conservation areas and listed buildings have additional rules. The pragmatic answer is to start with a site visit: we’ll flag any consent requirements based on the building, the plot and the local authority.
Because of the solid perimeter roof, orangeries usually trigger Building Regulations approval where a glazed conservatory might not. That’s nothing to worry about. It’s a normal part of the process and the inspection sign-off adds reassurance about insulation, drainage and structural integrity. The Government’s Planning Portal has the current detail.
Costs, timescales and the honest version
An orangery is a significant investment. Costs typically start around £35,000 for a modest installation and rise into the £60,000+ range for larger or more complex builds with high-spec finishes. Build time runs from six to twelve weeks depending on size, ground conditions and weather. We provide a fixed-price quote at survey and stick to it.
We’re a family-run business with no incentive to push you towards options that don’t fit. If a tiled-roof conservatory or a more substantial extension is a better answer than a lantern orangery for your home, we’ll say so.
Frequently Asked Questions
What’s the difference between an orangery and a conservatory?
An orangery has solid perimeter walls or piers, a flat perimeter roof and a central glazed lantern. A conservatory is predominantly glazed, typically over 75% glass, with a glazed or polycarbonate roof. Orangeries feel more like part of the house; conservatories feel more like an addition.
Do lantern roofs leak?
Modern lantern roofs from reputable systems don’t leak when installed correctly. Quality flashings, proper drainage and the right slope are the keys. We use systems that are pressure-tested and carry manufacturer guarantees.
How much heat does a lantern roof let in?
Solar-control lantern glass typically blocks 50-70% of solar heat compared to standard glass. Combined with the insulated perimeter roof, summer overheating is rarely a problem in a well-specified orangery.
Can I put downlighters in the perimeter roof?
Yes — that’s one of the practical advantages of an orangery over a conservatory. The flat perimeter ceiling gives you somewhere to mount downlighters, speakers and any other ceiling fittings.
How long does an orangery take to build?
Six to twelve weeks is typical, depending on size and ground conditions. Foundations, perimeter walls, roof structure, glazing and internal finishes are sequential, so weather and scheduling affect the timeline.
