Faithful readers who ploughed through my piece about Hall Houses last week may recall that I had quite a lot to say about timber framed houses and the skills and production methods used in their construction.
So I was delighted today to read an article in the Daily Telegraph about the carpentry skills which have been used to rebuild the roof of the fire damaged Notre Dame in Paris. For anyone who has access to the online Telegraph this is the article https://www.telegraph.co.uk/news/2024/12/06/glutton-punishment-british-carpenter-notre-dame/
The fire at the Cathedral, in April 2019, caused extensive damage to some parts of the cathedral but the windows and bell towers, relics and art survived the fire. But the spire fell, through the roof. The things which were extensively damaged were parts of the structure, some many centuries old, that most people probably didn’t notice when they visited. But, as the Telegraph noted, “as la forêt – the latticework of timber over the nave that had supported the roof for eight centuries – had been engulfed in flames and would need rebuilding.”
In the immediate aftermath, work began on finding craftsmen with the necessary skills to re-create the timbering exactly as it was and using the same techniques as 800 years ago, and also to find the timber required. That was the task of the French equivalent of the Forestry Commission who worked with the carpenters to identify the trees required for the work. Eleven principal trusses were needed and forty five secondary trusses, each 1.4m wide and 10m high. The task of carrying out the work was given to a group specialising in heritage projects – Charpentiers sans Frontières (Carpenters without Borders) – which brings together experts to work on historical construction sites.
English carpenter Mike Dennis is one of the small number of carpenters in the world with the skill and knowledge to undertake such work. And he was already living in France. Much of the work, according to him, had to develop from such plans and dimensions as they had available to them. The architect Remi Fromont had done a study of the roof in 2014 and his knowledge was vital. But to recreate the roof in every detail, as they were determined to do, meant drawing on many other resources, including trawling the internet for photographs visitors had taken, which might enable the carpenters to see details and angles of the trusses and tie-beams, including the carpenters’ assembly marks, to which I referred in my previous article.
Tree felling began in December of 2022 and the carpenters would go into the forests with a team from the commission to identify suitable trees for their purposes. They also had a team of blacksmiths who made tools, 13th century style axes, and gouges for them to recreate the marks on the timbers. The work was organised in much the same way as in a medieval workshop, Dennis says, the timber would arrive at the workshop, the carpenters would work on the trusses which would then be piled up ready to be sent to Paris as soon as the masons had prepared the walls. He describes the structure as “a flat pack on a massive scale”. All of the hewing and carpentry work was done by hand, with the carpenters working out the best and quickest ways to create what was needed with hand tools, just as the carpenters would have done originally. The only modern tool used was a circular saw to cut the joints.
The pictures from the restored cathedral look absolutely wonderful but you will not see la forêt – that is hidden above the ceiling but it is there, doing the job of holding up the roof, thanks to the wonderful skills of carpenters like Mike.
Mike Dennis is on Instagram and this is his page there – there are some amazing images of cruck timbers in various old buildings as well as his own work. https://www.instagram.com/mike_dennis_craft/?hl=en
Since completing this work, Mike has apparently been involved in a project to recreate the ship on which William the Conqueror sailed to England.
It was lovely to read about this work on Notre Dame and to realise that it was the same skills, on a smaller level which created timber framed houses in our past and in our neighbourhoods, and especially good to know, as the daughter of a traditionally apprenticed and trained carpenter, that there are still dedicated craftsmen keeping these skills alive today.
