I had a supervision yesterday with my supervisors Prof. Matthew Johnson and Dr. Graeme Earl where we discussed the first renders I had produced of my model so far. These images just detail the internal space: windows, fireplaces and doorways, and my first attempts at putting a roof and floors on the building.
I had been reading a lot around the subject of timber building construction to try to understand the appearance or these types of building. My first port of call was Richard Harris’s Discovering Timber-Framed Buildings this excellent little book explains the construction of these buildings in great detail with lots of helpful, clear diagrams. Based on his writings I started to plan the distances and shapes of my beams and how they would slot together. The following image is the results. I have just added some basic textures and materials to the renders to give an idea about the space that is not bright pink. I also realise that my smoothing groups need playing around with a bit.

The space the beams need to cross is quite short (about 5m) so there was no need to think about having to bridge the gap using a tie beam or similar approach. The distance the bays are placed apart does not seem to be set. I choose to space them evenly across the entire span about 5m apart as this “looked right” based on photos of other Medieval Roofs I had been using for reference (see below). Before spacing them apart I had to also consider the shape of this part of the frame. I had been looking at the above images of roof beams and decided to not go with a Crown Post and instead use 2 slanting Queen posts.

Presenting these images to Graeme and Matthew highlighted a few errors. Matthew suggested that the angle I had used for the Queen Posts was much too slanted, which is indicative of later buildings. Instead he suggested that it would be much more interesting to include a Crown Post or make the Queen Posts vertical.
As there are a number of options instead of just making one decision about how the roof is structured Graeme suggested that instead I create a number of different models with different roofing options, including a crown post and not, moving the number and position of bays around a bit to see if there are any obvious options for lining them up. We also discussed whether there would have been a ceiling concealing these beams. I had always assumed that the rooms would be open to the roof as this is common in halls. I had not really considered putting a ceiling in place on this upper floor.
What I had not considered was how much this changed the appearance of the upper apartment. Until now I had been thinking about them as looking fairly similar situated one above the other. However. when the roof is in place it will transform the upper apartment making it feel much larger and more open. Whereas the lower apartment will feel much more contained.
The second discussion point coming from the meeting was in reference to the beams and how decorated they were or not. We had been discussing them in terms of ornamentation of the type found at Ightham Mote (see previous blog). I asked whether, considering the lack of architectural ornamentation found at Bodiam, the beams, which would be cheaper to carve, would also be devoid of decoration. I had been thinking about it a lot as I need to decide whether I am going to shape them sooner rather than later. Matthew suggested that the question was even more complex as unlike a lot of slightly earlier buildings the household was not a peripatetic one, it was solely based at Bodiam. Which we would have assumed that more of the building would be decorated as it would not have had to have been moved around. So wondering whether the more decayed areas of the building are as plain as the rest of it is a very hard question, which I have yet to find an answer for.
