Restoring 600 Years Historic Roof Structure of Llwyn Celyn | Modern work in traditional way

Caelan is a project for the National Library of Wales The Llanddewi Brefi Library is launching the full service Confirm the accuracy of the farm resources and find a new period to use All resources were related to impossible negotiations The road planning resources deal with specific discussions themselves I am working on the project for the Caelan project I've been dealing with this for maybe 4 years now We actually started doing the periodic work in April of that year A little each day in reality Although the skills in terms of the resource We don't know what we will end up getting We know what some of the problems were We know that water is flowing through the resource We hope to reach more resources We clearly don't know much more than that So we have started to go up We have found water for the resource more water for the resource Add a little water to the resource outside the resource Most of this is done by interest from the resource to the resource The most recent decades This resource is very useful Therefore this is very important as a more comprehensive resource I will try to make the most of the resource I will try to take the most possible e original structure So what have we done with the resource We will do the most we can I am trying to produce its historical fabric therefore this can be seen by everyone Other resources around the organization more resources have been gained during 2 It is used as a valuable resource around the world In the same way the more and the less are more resources Felly we are not producing the extra resource we are not providing the extra resource Hanesol returns to the resources There was a shortage of all resources it was necessary to share them in order to have contact with the structure The additional resource being produced is related to more One of the specific areas where we have a problem is the additional resource between the soul and the right We have more resources to provide more resources and we do not do Common connection for additional resources there Therefore we have changed that They have even more resources for that But after that all that timber is In different environments more resources like more resources in this area The additional resource Because of the greater amount of timber we have contacted the examples Felly we have been able to design and publish the resources In one of the two environments we have taken additional resources to improve the difficulty And the resources have been very much given in a way that could We will share in the future or as they cannot see it as part of this resource Felly their services have been very difficult to support the carpenters and take them in The decision to share more resources for the future is not an easy one About examples connect understand the differences in future resources The Clwyn Celyn plan is for its resources Do you remember that we are talking abou Choose this one What choice then gives us the warning Well that's the choice after you came and the country They had shared the basic ones and started They were introducing them clearly It's a good choice indeed for an obstacle of 5 or 10 years I believe things have started to go well Therefore that 's why more steel is In the basics Well here are the basics This is the root the root that is received The steel parts are going to the material from the basic parts and you can feel them If you are giving your choice here Felly you can see here the tool one of the best steel ones and that's going Their tool is one of the basic ones Felly this decision is not to see any more steel here is This will be one of the most beautiful rooms It is going to be in the main room they have the equipment nice I don't want to see any more basic steel anymore and that' s why they keep it Their tool is one of the basic ones What we have done is sympathetic A challenge with the tool from the experts We do not provide external resources A new ID and basic details And that's important ere are many events of the basic elements and many basic elements We are not introducing it in a general way Therefore it is important that we do not start introducing it ernal resources in the basic room no If we had not introduced steel trusses We are at the steel mouth there the basic rations are failing then we will change The basic facts are throughout the report and that can be difficult for a historical report Otherwise we may be introducing the problem we are looking at it here and we will present this problem here Because we have changed the basic ingredients Therefore it is important What are we doing getting involved in the way The report has worked first First this road would have had a connection from this point along the way They are here This more is made on the way that this more is made The road here Introducing this one here We have introduced this part here which means the part ca To use it We can go back from that and then we had Do the rest of this to introduce where the rest of this from this side The wave of this majority occurred in the 17th century when this book was writte We have adapted them for the sacred purpose and we have allowed this part of the solar That's the rest This is part of the structure this way When we came to the entrance A chael y cilindwyd roedd y rhagor hon yn bwysig tuag at fe allan Felly with some buildings of the main rafters A raid its attack and its removal from the bridgehead We are reaching a point where we must leave the organization in order to campaign where it is necessary for us to be To produce the event from the stage and to send it back in its leaving The process of forging is a common part of shaping the blade on Clwyn Kellyn They stopped the cart from moving forward and backward They also have a creative job They are particularly taken with a part of the main raft They campaign in places where they are absent or in some places they campaign completely This is what we are trying to do this is what we are saying This is what we are saying my two sisters with a map of the night And a healthy appearance The gulls will return to the shore They will shop This is planning the resource board This will be placed inside the drum and the second layer will go on the outside In this area Lath Fawr we have already left the houses recently This will provide the painting supplies of the historical painter The second wave had a little second wave which was very good Finally were able to get 75% involved in writing That was not the comment when we completed the form We got 50% And when we got to show the forms You will be dealing with the institution and the building We have returned the exhibits to their original form It does that way We don't have the range of the form the range of the petrographic comments to understand well The geologist produces We are taking samples of the form from the core we are currently using They are connected in a way that we will get Many slopes are in the shape of a hill in Celyn and among the shape They are being notified of the Wales Form Today this form is interesting It appears to be an interesting phenomenon in the most noticeable forms You can do this in different ways and that was something I am very interested in myself and in the people who work for me They found the way to the experience as it says They are saying this in the Welsh style There is lead in the detail At present this form has been made with lead or fibreglass Every year they were unable to obtain a license and were unable to obtain a fibroglas Felly how did they do this in such a way Anything that comes in They are going down there And we are trying to take them with the thing that is going down Felly we are trying to take anything that's going down there I will take the path that goes down The original form is related to He can imagine a big form The shape was established with a set of brushes and the shapes were made with pegs so that they can be attached one for each which are locally sourced It is moving forward This form relates to the original form and the original form This form connects the designs that will kill cases The large form in the water and the large form and line in the water The designs of the first In your home make them safe before you teach them When other designs are being copied The operators are consulting the tower in order for them to ge They are available in their original form We will go to the tower from the way that we have a 30 30 inches 30 inches is the longest that they have So we know where we are We've basically gone from a 30-inch-long slate all the way down to a 10 at the top Obviously it'll Give a seamless effect There will be no jumps in the course as you'll see as it goes on Up Even though we are dealing with a historic roof modern day building regulations still Apply to ensure that it performs correctly British standards regarding overlaps are based on a building's location and the angle of the pitch of the roof Basically it's a heavy rain index and the area where we are is classified as severe Everything from west Wales and further over basically along the west coast Scotland England Wales and so on are classified as very severe So then it basically tells us On here so we're in severe here So we know the roof pitch is roughly 45 degrees so that we know it'll tell us there we're over here So we know our minimum head lap is 69 Right so this is the Beast House This is going to be an interpretation center This building like the house has suffered from neglect It has had some propping and shoring up over its history but the wall behind me here on the north side had developed a significant bow in it which was a major concern for the engineer We've actually now had to take Bring it down to the foundation and rebuild Structural problems like this have been resolved in different ways across the Clwyn Kellyn site These conservation dilemmas have been the subject of on-site training for students and professionals In an ideal world we would just be taking a pure conservation approach to every aspect of every project but there isn't enough money available to do that So at some point we have to be a little bit pragmatic about our approach and on this site the beautiful The thing is that we have a cluster of buildings so we can take a different approach with different buildings With historic fabric we have to understand how we've gotten to the point tha We've got to now and what we're going to do to make sure we secure that fabric moving forward The roof here is going to use stone tiles again which blends this building in very nicely with the house So we'll remove the profiled tin sheeting and put the stone tiles back on e roof So we need to be sure then that the whole of this roof structure is in good order to take the terrific weight of all the stone tiles The engineer's had an early Look at the roof We've identified one or two additional repairs that we need to do here hopefully nothing too major The whole of the structure has moved south There are buttresses on the outside of the south face of the wall which are obviously holding the building up and there's one tie On this truss on this side here where they should normally act in tension it appears to be acting in compression and has got a banana curve in it It's obviously It has been put under some considerable strain in its lifetime Right so this is the threshing barn and this building is going to be used now as a community use space The building has in its lifetime been re-roofed We don't know Whether it originally had a stone tile roof but there's evidence that the ventilation slots have been cut through so we're pretty certain this roof has been lowered so it may We have had a stone tile roof in the past but we're going to simply put back a profiled tin roof insulated so that it makes the space more comfortable in the winter months Obviously Block up the slots with glazing One of the big problems we have here is that the gable wall on the east side was slipping down the valley and hence the strapping and Cantilever there to hold the wall in and stabilize it The roof structure is currently a series of iron frames We are discussing with the engineers whether we can have These are repaired There are one or two bolts missing so it may be that simply by putting the bolts back we re-introduce this integrity The alternative was to have some new timber A set of trusses made up but like all these projects we don't want to spend money unnecessarily So if we can make use of or reuse these frames then we will The project to save Glewing Kellyn has posed many challenges for the team The advanced state of decay of all the buildings has meant that no single approach to conservation could be applied The project team guided by our structural engineer were able to weigh up the needs of each building against its end use while keeping costs in check This fluid and informed approach has ensured tha The maximum amount of historic fabric has been preserved along with the character of each building
