Luxury Orangeries

Get Your Designs

A stylish and luxurious design to complement any property, an orangery harks back to an era of grace and glamour. Historically, they were a practical garden building for the cultivation of exotic shrubs and trees and could only be afforded by the wealthiest of families. Since then, their uses have diversified and expanded.

Today an orangery is a sophisticated home extension and an enjoyable living space, available for almost every budget. In terms of construction, they’re similar to a conservatory, but it has a more solid structure. Dwarf walls can run around the edge of the building, and the edges of the roof are also solid. The rest of the roof is still glass, so the room will be flooded with light and warmed by the sun.

Grow Your Home with an Orangery

An orangery is a great way to add value and space to your home. Less expensive than a traditional extension but more hardwearing than a conservatory, it will be an integral part of your home for years to come. In fact, with its hard wearing and durable design, it’s much more likely to be decades of enjoyment from your new space.

Our patented designs enable us to provide you with your dream orangery. Whatever style you go for, you will create a stunning and practical living area. Choose from our variety of features, styles and colours to make it as individual as you are. You can get in touch with our expert team to start designing your dream extension today.

The Perfect Temperature, 365 Days a Year

Orangeries and conservatories both come with preconceptions of a space that’s too cold in winter and too warm in summer. In decades past, this may have been true, but it’s no longer the case! They are built to the latest building regulations, which ensure a great level of thermal efficiency.

What does this mean for your home? Adding a new orangery will mean growing your home with a space that stays the perfect temperature all year round. With double glazed windows, a host of weather seals and a thermally efficient roof, you can forget about extreme temperatures. Instead, you’ll be perfectly cosy 365 days a year.

Frequently Asked Questions

What's the difference between an orangery and a conservatory?

Orangeries generally have more solid construction, particularly on their roof, than a conservatory. With Britannia, both will provide an excellent level of performance for your home.

Are they Building Regulation compliant?

All of our orangeries are supplied from the leading name Ultraframe. They have ensured that the designs are completely compliant with the latest Building Regulations.

Do you have a showroom?

Pay a visit to any of our showrooms to see our home improvements in person. You can find them in Bristol, Clevedon and across the South East and South West.
