With over 50 years of expertise since our founding in 1972, we offer a full turnkey service, managing every aspect of your orangery installation in-house.
What are Orangeries?
Orangeries offer the perfect balance between conservatories and house extensions, blending solid brickwork with expansive glazing to create a bright, stylish, and energy-efficient living space.
With our bespoke design service, you can customise every detail to complement your home. From premium aluminium windows and doors to a tailor-made Ultraframe roof system, we provide everything you need to bring your vision to life.
Why Choose an Orangery?
Struggling to choose between a conservatory and a house extension? Why settle for less? An orangery offers the best of both worlds—a private, well-insulated space that remains seamlessly connected to your patio, garden, or outdoor area.
Beyond enhancing kerb appeal, orangeries are incredibly versatile. Whether you envision a sunroom, home office, open-plan kitchen, gym, or playroom, they can be tailored to suit your lifestyle, making them a stylish and practical addition to any home.
