Specialist Roof Glazing for Historic and Public Buildings: Martin Johnson & Co is a leading specialist in the manufacture and conservation of large-scale rooflights, laylights and decorative lanterns for historic and public buildings.

From Design to Installation: We take bespoke roof glazing projects from initial concept through to completion, combining practical design expertise with specialist manufacturing capability.  Our frames are elegant, structurally appropriate and sympathetic to their setting, with associated glazing manufactured and installed to suit each project.  We also work closely with clients’ structural engineers and external designers where required.

Conservation and Restoration Expertise: Our heritage glass conservation experience, supported by a specialised metalwork department, makes us ideally placed to resolve the complex challenges of historic roof glazing.  In line with conservation best-practice, we retain as much historic material as possible while delivering beautiful and durable glazing structures that are fit for the future.
