An orangery is defined by its roof: a solid perimeter with a deep internal pelmet, and a glazed lantern rising from the centre. Get the lantern's proportion right and the whole room works; get it wrong and no amount of brickwork saves it.

We supply and install orangery lanterns sized to classical proportions, with pelmet design guidance, perimeter lighting detail and aluminium or timber construction.
Orangery lantern design follows a few reliable rules: the lantern occupies roughly half to two-thirds of the roof's footprint, the pelmet returns 600mm or more for that signature shadow line, and the pitch lifts towards the traditional 35–40 degrees for presence. We help size the lantern to the room before anything is ordered — a sketch over your plan costs nothing — then build in the practical layer: LED perimeter lighting in the pelmet, speaker positions, and trickle-vent or opening-pane ventilation where the room needs it. Aluminium in heritage colours covers most projects; timber answers the strictest period briefs.

As a rule of thumb, half to two-thirds of the roof footprint, holding at least 600mm of solid pelmet all round. We'll sketch the proportion over your floor plan before you order — it's the decision that makes or breaks the room.
Yes — that's the classic orangery detail. We coordinate lantern kerb positions with your electrician's first fix so LED strips or downlights wash light around the glass at night.
They can — electric opening panes with rain sensors are available on most systems, and worth specifying in kitchens where extraction and summer heat both need help.
35–40 degrees for the traditional pavilion presence orangeries are known for. Contemporary orangeries sometimes drop to 25 degrees, but the taller pitch remains the signature.
Heritage aluminium suits most projects — period looks, modern performance. Timber earns its premium on listed properties and exacting conservation briefs.
