Last year I conducted repairs on the windows of an Alexander (Greek) Thomson designed house, and for the last six months or so, I have been involved in repairs and other work on a Lutyens designed house.
The stair windows had some cracks and was producing a lot of condensation. As the roof was being repaired, the opportunity was taken to have something done about the window.
As you can see the window is awkward to get to so the roofer's scaffolding was essential. The window panel was bowed with a number of broken lead joints. The window is also installed directly into the stone, so there were additional breaks in getting them out. The iron work of the opening panel was completely corroded and covered in putty to try to weather proof it.
The decision was taken to re-lead and replace the broken pieces with a very good match of glass made in Poland (locally called Tatra glass). The opening panel was remade to be fixed into the stone. The weep holes were cleared to disperse the condensation as originally intended.
The resulting finished window appears to be the same as the original. The repairs are not distinguishable except by close examination.
The house also has a heavy external door that previously was solid. The owners wanted more light into the hallway behind and proposed opening the wood panels to accept leaded glass.
After looking at some of the leaded window designs around the house a lozenge and diamond design was chosen. This shows the completed door from the interior.
The door from the exterior still maintains an imposing presence, although softened by the insertion of the four panels.
