Crittall-Style Glazing in Listed Buildings
In listed buildings, Crittall-style glazing can often be added to later partitions, service areas and new openings, but any change that affects the building's character needs listed building consent first.

Conservation officers usually prefer changes that are reversible and clearly modern rather than fake-historic. A slim, well-detailed glazed screen can meet that test better than a solid wall.
We prepare drawings and specifications to support your application and work to any conditions that come with the consent.
What to plan for
- Listed building consent comes first
- Reversible fixings are favoured
- Drawings support the application
- Secondary glazing may suit original windows better

Is it a criminal offence to alter a listed building without consent?
Yes. Unauthorised works to a listed building can be a criminal offence, so consent must be in place before work starts.
Can you replace original metal windows in a listed building?
Usually only with consent, and repair is often preferred. We can advise on matching replacements where replacement is accepted.
