Modern Orangery Extension


Orangeries offer Dorset homeowners the best of both worlds, intelligently combining the light and glass that conservatories provide with the insulating walls and ceiling of an extension. Seamlessly bridging the gap between a conservatory and an extension, their partially solid, multi layered structure provide homeowners with a multitude of benefits.
