Conservatory or Orangery, Which Is Right for You? 🏡

It's one of the most common questions we get asked, and it's a great one!

Both add beautiful living space to your home, but they're not the same thing.

Here's a quick breakdown:

🪟 Conservatories
Mainly glass - roof and all.

They flood your home with natural light and come in styles like Victorian (that classic curved bay front), Edwardian (square, great for space), and Gable (high ceilings, very contemporary).

Because of the glazed roof, they can feel warm in summer and cool in winter - but modern glazing and roofing options have come a long way!

🧱 Orangeries
Think of an orangery as the middle ground between a conservatory and a full house extension. They have solid walls with large windows, and a flat roof with a lantern light in the centre.

They feel more like a proper room - warmer in winter, cooler in summer - and they tend to blend more seamlessly with the existing brickwork of your home.

So which should you choose?

➡️ Want maximum light and a classic look? Go conservatory.

➡️ Want something that feels more like a room, year-round? An orangery could be perfect.

Either way, we manufacture everything right here on Teesside and our team handles every installation, no middlemen, no subcontractors.

👇 Come and see both in our Middlesbrough or Stockton showroom, no pressure, just expert advice.
