We Build Beautiful Orangeries Orangeries are a great addition to the conservatory family; Unlike traditional conservatories, they have solid brick walls. They are incredibly sturdy and are a great addition to any home. They are combining the glazed roof of roof lanterns with the solid walls of a traditional extension. The exterior brickwork can be matched to your existing property allowing for a pleasing visual integration between the old and new.

Inside, a plastered perimeter ceiling can house downlights, and the solid walls can incorporate as much or as little glazing as you like. An orangery successfully bridges the gap from the Conservatory to traditional Extension.
As with all our Conservatories, we use industry-leading software this allows us to design your orangery, ensuring a perfect installation while also deal with any planning requirements necessary for the build.

Orangery Roof Lanterns
All our orangery roof Lanterns are glazed using Pilkington active self-cleaning glass and are available in a choice for colours. All our roofs come with a full 10-year guarantee.

Orangery Walls
Orangeries have a brick wall construction. Our Orangeries in London are designed and skillfully installed, ensuring quality from start to finish guaranteeing that your orangery is long-lasting and durable as the rest of your home.

Customer Reviews
David Strange | London
Really great job done by Peter and his team. They replaced all the windows in our 3rd floor flat, quickly and matching the old design exactly. Peter provided very helpful advice as to which type would be best for our needs (we went for double glazing with extra accoustic glass) and he also gave us a full break down of the pricing etc. Not at all pushy, just a decent window fitter who did a very professional job. We have already recommended them to all our neighbours and I would highly recommend South East windows to anyone.

Paula Adams | London
Can't tell you how happy I am. Peter fitted french doors and side panels last month for me. Great service from first visit for quotation to completion of work. Straight forward no nonsense, what you see is what you get! Peter worked tirelessly and the level of workmanship was second to none! The doors look fantastic and the finish is perfect! Thank you so much Peter. I will definitely be back for the windows very soon. I would not hesitate to recommend you to anyone. Great quality, workmanship and price!
