Transfiguration Classroom

In the early Potter films, scenes in Professor McGonagall’s Transfiguration classroom were shot on location in the chapter house at Durham Cathedral. As part of their efforts to make the original exterior miniature somewhat consistent with the location shoots, Stuart Craig and his team adapted the exterior of the chapter house as part of their design.

I say “adapted” because the details don’t really match. Still, it’s very clear that this structure just south of the middle courtyard (also adapted from Durham) was intended to be the exterior of the classroom.

Here’s the basic shape of the structure:

My “reference board” for this structure is one of my smallest. This is partly because it only existed for two films and partly because it’s not that big or complex a structure…but it’s also partly because reference is really, really scarce. Like…a couple of shots in Chamber of Secrets and a behind-the-scenes photo from Sorcerer’s Stone, plus the floor plan that sits beneath the model. Still, it’s enough to reconstruct what most of it looked like…

…except I have literally zero shots of the far side of the structure, the one facing the courtyard. I’d be in heaven if I could find a shot of the original miniature from an angle like this:

It would clear up my questions about the side of the Transfiguration classroom facing the courtyard, not to mention the original training grounds tower roof on the right. Again…maybe someday. In the meantime, I’m leaving the wall facing the courtyard blank.

Anyway, here’s the less mysterious side with all the nice details:

And, as promised last time, here’s a slider comparing the whole area in the first film (left) to the redesign in the third film (right), including the relocation of the suspension bridge:

Next up…dare I try to tackle the original quad?

Suspension Bridge & Gryffindor Girls’ Tower

When we last saw the Hogwarts suspension bridge in my project, it was an untextured but fairly complete bridge to nowhere. Then, a few posts later, I said that I’d hidden the bridge so I could do some reworking, and that it would return “eventually.” I didn’t really expect that “eventually” would mean two years and a pandemic later, but there ya go.

In the intervening time, I discovered some issues with my original recreation of the bridge, so I just rebuilt it from scratch. The suspension bridge moved in Prisoner of Azkaban; I decided to start with that version, as I did two years ago.

I found that the two ends of the bridge weren’t quite lining up, but that problem went away with some slight cheating.

One challenge is that our only truly close-up view of this bridge in the films is during the dragon chase in Goblet of Fire…but that shot features a different design, and I’ve chosen to ignore it.

Adding the details, and hiding the buildings to the north so we can get a better angle (and let some more light in):

I suppose it’s only fair to also include a reverse angle, this time hiding the south block (and rotating the sky/sun 180°):

But of course, as I said, this is not where the suspension bridge started out. Originally, it was closer to Gryffindor Tower and lower down – in fact, you can see the small building it originally led to on the far left side of the render above.

Back on the opposite (south) side of the ravine, the tower containing the Gryffindor girls’ dormitories originally stood directly above the other side of the bridge. (Not going to dig into the design choice to deprive the girls’ tower of a spire or any discernable windows…) That tower disappeared completely when the suspension bridge moved in Prisoner of Azkaban, although the Gryffindor common room set still hints at its existence.

Again, it’s easiest to see this with half of the castle missing. Drag the slider to compare Sorcerer’s Stone (left) to Azkaban (right):

I should say that I am NOT confident in the accuracy or completeness of the lower left area of the wall in the Sorcerer’s Stone version. The floor plan seems to indicate some sort of terrace or balcony; if it was actually built, I’d imagine it was similar to the one on the right side of the render, in appearance and height. Sadly, I simply cannot find any reference for this area of the original model, so for the time being, I’m just building the main wall itself. Someday, man…someday.

I’d like to show you a similar slider facing the opposite direction, but I think that’ll be more fun and more informative once I’ve built the Transfiguration classroom (AKA Durham Cathedral chapter house). That’s next up on my to-do list…stay tuned for more updates! In the meantime, I’ll leave you with a more familiar Sorcerer’s Stone angle of the suspension bridge area:

And hey, why not – just as a fun bonus, here’s an overhead shot, but with the SS and POA versions both visible and intersecting nonsensically. I’m including the mist pass too because it just looks frickin’ cool.

…and the “Sorcerer’s Stone” Training Grounds Tower!

We’re gonna start today’s post with the good stuff: before-and-after sliders comparing the COS-through-OOTP training grounds tower I finished last time to the original training grounds tower! (I’ll show you the process of creating the latter afterward.)

For each slider below, the SS version of the tower is on the left and the COS-OOTP version is on the right. Notice how little the lower areas of the structure change, and how much the upper areas of the structure change!

Before I built this original version, I realized that I didn’t have the adjacent areas built in the SS model, which would make it look kinda funky. So I first took care of some housekeeping: duplicating stuff from the POA model to the SS model, creating new collections (folders) for different structures, etc.

The Defense Against the Dark Arts tower moved in Prisoner of Azkaban, so I created a copy of it and moved it to its original position. I also removed some asymmetry from the Durham wing that was introduced in Azkaban to make room for the Dark Tower:

God, I get so nostalgic for those candle snuffer roofs on the Durham wing from the first couple films.

Anyway, as you’ve seen with the sliders, the lower areas of the COS-OOTP training grounds tower are identical to the original design from SS; they just redesigned most of the upper areas. So I brought a copy of that training grounds tower into the SS model and started ripping off all the top parts that were different. Here’s a fun render partway through that messy process:

Ugly, innit? Well, if you want to make an omelette, you’ve got to crack some eggs.

There, now the metaphorical eggs are beginning to set! Nearly done:

The roof is tricky because in addition to the gable, there seem to be some flat areas, but I don’t have any good shots from above. This is another area where my ideal levels of accuracy and precision simply aren’t going to be possible, unless some kind soul manages to send me reference photos or technical drawings of this spot that hasn’t been part of the miniature for almost 20 years now.

This seems to be the best inference possible from the available information:

Its central courtyard is particularly mysterious. It corresponds to a space at Alnwick Castle that was used in a brief scene in the first film, but the shape is so different in the miniature that it’s impossible to know what sorts of architectural details were in there. In the video game, the courtyard is omitted altogether, continuing the flat roof over the entire thing; you can see it at 3:07:02 in this video. But that castle has numerous other inaccuracies, so I take it with a grain of salt.

One of the things that’s starting to stick out for me is the lack of flashing on all my roofs. It definitely hurts the realism. I’m going to need to fix that at some point.

Anyway, here’s one last shot of the finished tower! Next, I’ll probably finish up the SS-era curtain walls. See you next time!

What Was There Before the Hogwarts Greenhouses?

It’s not a question that you could answer just by watching the films. Here we have to rely on behind-the-scenes shots and technical drawings from Sorcerer’s/Philosopher’s Stone to reconstruct this area in its original state.

But first, I knew I needed to finish up this area as seen from Chamber of Secrets through Half-Blood Prince! I finished the curtain walls and added lawns:

Here’s a cool POV shot coming down the back steps of the Durham building:

That’s a wrap for this area in the Prisoner of Azkaban 3D model! But what did it look like at the time of the first film? Well, you still had curtain walls surrounding a large, L-shaped lawn, but the walls weren’t quite as far from the castle, and instead of the domed conservatory acting as the entryway, you had this relatively simple, squarish, Alnwick Castle-inspired building:

This side of the building is actually seen in a couple of shots in the film, but I haven’t been able to find as much detailed information about the other sides – in particular, the opposite side that faces the castle proper. For that facade, I’ve just used the same details as what you see here, but I can’t deny the possibility that some of the details were a little different. (I wonder in particular if they really would have put the Hogwarts crest on the other side.) Unless I find elevations or images of that part of the miniature, I may never know…when the greenhouses and conservatory were added in COS, this small gatehouse disappeared forever.

Anyway, here are a couple of before-and-after sliders to play with! On the left is the Sorcerer’s Stone castle; the right is Prisoner of Azkaban. (The changes we’re currently focused on occurred in Chamber of Secrets, but you’ll of course see some Azkaban changes too.)

I’ll wrap up this post with a view of some additional work I did next on the west side of the Alnwick Castle warder’s tower. Here there are again some details that differ a bit between the VFX miniature and the real-world filming location; I’m primarily going off of the miniature, though Alnwick does provide invaluable reference as well. I guess you could say my goal is to capture the shared imagined reality that the model and the location both help bring to life.

The two contenders for my next area of focus are the transfiguration/middle/Durham courtyard and the training grounds tower. I’m much more excited at the prospect of doing the latter, but I think I may tackle the courtyard first. Be sure to subscribe to be notified with future updates!

Finishing the Bell Towers – “Azkaban” AND Original Versions!

Here we go – those bell towers need to be completed. I finished the intricate openings and decorative motifs in the middle parts of the towers. Fortunately, these never changed in any of the films, even when the tops of the towers changed, so I only had to create them this once!

Then, to complete the bell towers, I added the tops of the towers, which are very similar to the top of the central tower – just shrunk by about 23%, and with a few minor design differences. I was grateful for this not only because it allowed me to reuse elements from the central tower, but also because I discovered a mistake in the central tower in the process. All fixed now!

Of course, there are two versions of the bell towers: the original design, and this Prisoner of Azkaban redesign. With the latter complete, I decided to switch over and do the former as well!

Sadly, photogrammetry is no help when it comes to the original tops of the bell towers, but their simple design is pretty easy to eyeball. A few of the smallest details were educated guesses – for instance, I’ve added windowpanes in a few areas that could just be openings.

Anyway, enough talk – let’s compare the two designs! Drag the slider below to compare the original Sorcerer’s Stone design (left) to the Prisoner of Azkaban redesign (right). (The smaller tower above the Long Gallery will also come and go, since that was added in Chamber of Secrets.)

Here’s a reverse angle:

Surprise – there’s the original design of the central tower, too! I snuck that in there as well.

Viewing the whole castle from lake level, you can really see what a difference this simple redesign of these three towers made in the castle’s overall silhouette and character. My model is also looking a lot more complete overall!

Adding the wall between the bell towers was easy, since all of its elements are similar to stuff I’ve already created. I briefly considered tackling the greenhouses next, but then I got distracted by the adjacent walls that bring us to the training grounds tower and the middle courtyard, which will probably be where I go in our next blog post.

In the meantime, Ms. Rowling continues to tweet disappointingly misguided things about transgender people. For what it’s worth – if you, dear reader, happen to be trans, non-binary, or a member of any other oft-marginalized community, know that this Hogwarts (incomplete though it may be) will always be there to welcome your awesome self, and so will I.
