The Metal Window Refurbishment of the British Muslim Heritage Centre.

The client, James West Construction Ltd approached us to complete the metal window refurbishment at the British Muslim Heritage Centre in Whalley Range, Manchester, UK. This Grade II* listed Gothic style building was built in 1843. It was originally the Lancashire Independent College. It is now undergoing redevelopment into a community centre and venue.

Forty nine metal windows needed various types of refurbishment. We needed to ease and adjust most of them. We also repaired/replaced missing window furniture, leaded lights and glazing.

A cast brass drop loop cockspur catch. A bespoke cast brass replica drop loop cockspur catch matching a missing original fitted on a refurbished flat iron window.

Window frames had been replaced during the building's history. There were designs from different periods. We repaired:

  • Flat Iron Casements
  • Crittall Casements
  • Horizontal Pivoting Windows
  • Top-hung Windows
  • Leaded Lights
  • We manufactured and replaced:

  • Sliding Stays
  • Cockspur Catches
  • Faux Forged Stays
  • Pulley & Cord Closing Mechs
  • Diamond Leaded Light Panel
  • Glazing To Stone Mullions
  • A before and after photo of a replacement leaded light. The original leaded light was beyond repair. It was short on the height and width so didn't fit into the stone mullion glazing channels properly. The new leaded light panel fit neatly into the original stone channels.
    A photo showing two cockspur catch designs. One for inward and one for outward opening casements. We had to manufacture left and right handed cockspur catches. There was also a different backplate and a keep for inward operated casements.
    A before and after photo showing a conservation sliding stay assembly We manufactured a conservation sliding stay to replace the one missing on this inward opening casement. We took multiple moulds off an original and made pattern work. The resulting brass castings were engineered, assembled and fit into the original brackets.
    A photo showing glazing fixed direct to stone mullions. We replaced some of the glazing fixed directly to stone mullions. We removed old putty and broken glass from the glazing channels. This allowed us to slide 3mm glazing into place. The glazing was bedded in and pointed with lime mortar.
    Bespoke cast brass conservation window furniture assemblies. Apart from the fanlight catches we moulded and made replicas of existing original window furniture replacing all those missing throughout the building.
    A refurbished horizontal pivot window. We worked at height on an access tower to ease and adjust the twelve horizontal pivot windows in the main hall. Seven of the windows needed converting from a simple cord operated open/close mechanism to a fanlight catch opening and a pulley cord closing mechanism.


    This project was a real challenge. It required easing and adjusting of the metal frames but also mould making, bespoke metal window furniture, leaded light manufacture, glazing and pointing skills. The bespoke metal window furniture manufacture is something that we'll be expanding on in the near future so if that is something that interests you then perhaps it is worth giving us a call.
