We Build Beautiful Orangeries Orangeries make a fantastic addition to the conservatory family. Unlike traditional conservatories, they have solid brick walls, making them incredibly sturdy and a valuable addition to any home. Orangeries combine the glazed roof of roof lanterns with the solid walls of a traditional extension, resulting in a beautiful and functional space. Additionally, the exterior brickwork can be matched to your existing property, allowing for seamless visual integration between the old and new.

The interior of the orangery boasts a plastered perimeter ceiling that can accommodate downlights, while the solid walls can feature as much or as little glazing as desired. This type of extension successfully merges the Conservatory with traditional architecture. We utilise cutting-edge technology to design your orangery and guarantee flawless installation from start to finish.

Orangery Roof Lanterns
Our orangery roof lanterns are crafted with Pilkington active self-cleaning glass and are offered in a range of attractive colours. We provide a comprehensive 10-year warranty with each of our roofs.
Orangery Walls

Our Orangeries are constructed using brick walls, ensuring durability and longevity for your home. We take pride in our expert design and installation services, providing quality from start to finish. Rest assured, your orangery will be just as sturdy and reliable 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!

High recommendations for Southeast Windows. Roy was a pleasure to deal with and was always happy to assist with his extensive experience in the industry which really shows though. Would definitely recommend Southeast Windows to all friends, colleagues and family. Roy done an excellent and professional job with no pushy sales and great aftercare along with honest and upfront advice and assistance- what else can you ask for? Thanks again.
