Hogwart's Castle (71043) Epic Extension

FOLLOWERS

LIKES

Lego did an amazing job with the design of Hogwart's Castle, but Harry Potter fans wanted more. Ryan Kroboth delivered with his epic extension to the castle.

Ryan did a fantastic job with this design, filling it full of detail and adding in all the buildings not originally found in the main set. He seamlessly integrated the original set into his expanded design, so you can't tell where one begins and the other ends.

I was contacted by a client to make step by step instructions for this design. And with Ryan's permission I can now make those available to all the Harry Potter fans who want to make their Hogwart's set truly amazing!

The step by step instructions come in two parts with a total of over 3000 pages

There are three digital files, to help you navigate the design easier. One with the small part of the extension and one with the large section, as well as one showing the design all together so you can see how the parts fit with the original model.

Directions to the Step by Step Instructions, open the file. Click the Tool menu, then Instruction maker. You can either follow the directions in the Page Design tab from there or export the directions to a PDF.

Note: Some of the parts in Ryan's original design are older versions of parts. You will want to change those to currently available parts when you make your part orders, as this will significantly lower the cost of those parts.

As all fan designers I do this for the passion of Lego but do need to pay the bills like everyone else. If you do buy these instructions, please do not share them out. The cost in low enough to allow any who wish to own it to do so. Thank you.

FAQ

"Do you have an estimate of the size/measurements (Height x Width x Depth)"
Width 130.6 cm (51.4 in) Length 93.7 cm (36.9 in) Height 62.8 cm (24.7 in)

"The part count of 19k on Rebrickable, is that including the 6k of the original Lego set 71043?"
The 19k in parts does not include the original set

"
Are there any base plates included in the extended part of the build?"
No, there are no base plates in the design.

"Any stickers, printed bricks, hard-to-find pieces or customized parts used in the extended buildings"
There are some hard to find pieces. There are some pieces where the original designer used out of date parts, but those can be substituted for currently available parts.

"Can the 1x2x5 Brick Blue by Qty 241 and Technic Brick 6x8 Open Center by Qty 167, are these colour specific or can they be any colour"

They can be any colour as they just form the sub structure.

"Are there any other parts or colours that con be substituted for any colour. Just trying to reduce cost of parts?"

I am sure there are, for instance the large lbg plates under the large extension could be switched out with no visible effect. 


I would suggest going through and checking out the sub structure in the sub models and see which parts could be swapped out that would not change the exterior colours.

There are also some older parts that can be swapped out for newer versions as well, making them a bit cheaper, Bricklink will probably catch most of those for you.

"How much would the parts cost and how many Hogwart's sets should I buy to complete this?"

A very nice member in a facebook group did the cost breakdown in Canadian dollars


Attila Szabo
 "So I did some research. For 19275 parts on BrickLink using only Canadian vendors the cost would be $2292 plus shipping from multiple vendors. I then deducted the useable parts from 71043 (since I own one) leaving 15343 parts to order. BrickLink was then $1780 plus shipping from a bunch of vendors. So about $512 cheaper. So kind of makes sense to do this as you end up with a couple thousand leftover parts from 71043. Adding in another 71043 set only got the price down to $1557 plus shipping, so only saving $223. So it seems like one 71043 set is optimum."


Thanks Attila!

          Je dient het gratis programma Stud.io te downloaden. Met dit programma kun je de .io bestanden openen die je hebt ontvangen toen je de instructies hebt gekocht. Eenmaal in dit programma kun je zelf de bouwinstructies genereren. Deze instructies zijn 3000 pagina’s groot dus vandaar dat de bedenker van dit model niet direct de pdf kan delen.

    Oof 60$ For the instruction... I wanted to build it on my computer... Anyway this build is AWESOME ! 👏 Bravo !

    PS: does someone build it in real life ? If yes I would like to see it !
  • 1 month, 1 week ago oceanic Level 3
    Just awesome!
    I´m already sorry for asking this as the anwser surely was already put somewhere here but I just want to be sure: I already built the 71043 castle. Do I just need another 71043 set to get all the needed parts for this extension? Many thanks!
    • 1 month, 1 week ago Playwell Bricks Level 11 Designed this MOC
      Hi Oceanic

      I answered that question in the description, but in short, if you buy a second Hogwart's it will dramatically reduce the number of parts you need to complete the extension but you will need many more parts beside. The extension itself is over 19,000 pcs.

      If you have any other questions feel free to ask :)

        Many thanks!
        But if I would buy 2 71043 sets for the extension there would still some parts missing, right?
        The link "buy parts" shows different % of the parts. Does this mean some vendors aren´t able to serve some parts? Sorry for all the stupid questions, I´m new to this (not LEGO *lol)
        Thanks in advance!

          Hi Robin

          No problem, I will attempt to answer your questions :)

          But if I would buy 2 71043 sets for the extension there would still some parts missing, right?

          Yes, you will need extra parts to complete the extension besides the Hogwarts set.

          Does this mean some vendors aren´t able to serve some parts? 

          Correct, you will most likely have to go to multiple vendors in order to accumulate all the parts you need for the build.

          Don't hesitate to ask if you need any more help :)

      I've used a second 71043 set to build the small extension. There were 2887 parts I could use and I've had to order another 3554 parts to complete the small extension. If you build the complete castle you could use an extra 1042 parts from the 71043 set so a grand total of 3929 parts could be used.
      • 4 weeks ago SSHO Level 11
        Thank you for that information, I plan on doing the small extension first to give myself some time to gather the parts for the larger section.  I also plan on purchasing a second 71043 to help that along as you did.  Were the remaining parts difficult to locate/purchase, and if not would you mind giving me a cost estimate on your experience purchasing them?
        • 3 weeks, 5 days ago Freezer118 Level 7
          Luckily this MOC uses mostly generic bricks and generic colors. Some pieces are a little more exclusive (and thus more expensive) but if you take a closer look at the model they can easily be replaced for a cheaper option. There still is a lot of part optimization to be achieved in this model. 
          The LEGO average of 10 cent a piece is quite reasonable for this MOC. So approx. 600 €/$ for the small extension and 1200€/$ for the large extension excluding the use of a second 71043 set and excluding shipping and handling.

    Hi,
    at first: Congratulations to this beautiful MOC. Now it ist my work to look for all the parts, so that my wife can have al lot of fun.  :-)
    The problem I have is, that the parts in your list have complete other numbers than the numbers in my instructions.
    for example: your number 6082 is in the instruction of Lego 71043 the number 6143428;  or in your instruction at the first step for the extension ist the first part the number 40345. This number don't exists in your part List.

    Now I am confused. ;)  Can you help me, with the Part Numbers?
    vlg, Andrew
    • 1 month, 3 weeks ago Playwell Bricks Level 11 Designed this MOC
      Hi Andrew

      No problem :) The issue is that some parts have minor variations, and each variation has a different part number. As well Bricklink part numbers and Lego parts number are not the same, just to add to the confusion.

      The part number 40345, has an alternate part number of 32532.

      If you need any further help feel free to ask :)

  • You've made the most impressive Hogwarts Castle I have ever seen. Too bad it is not minifigure size. Excellent job

    Decemeber 15th, 2019 Update

    During the build a customer noticed some minor design issues. I have uploaded a new file with the corrections and corrected the parts list to reflect the changes.

    Specifically there were two bricks added to a couple of steps a 1x2 DBG brick and a 1x1 DBG brick.

    Also in Ryan's original design he had a connection for the lamps on the bridge that wouldn't actually work. That has been corrected. 4 - 1x3 black pins have been replaced by 4 - 1x2 black pins and 4 - 1x1 round plates with a center hole.

    Sorry for the inconvenience. If you have any questions about these changes please contact me.

    Sincerely,
    Jason

      Hi Jason,
      When I download the new file from dec 15th I don't see any difference at the lights on the bridge. Still 4x 1x3 black pins holding the lanterns. Am I correct?
      • 2 months ago Playwell Bricks Level 11 Designed this MOC
        There should be a change, let me check it again and get back to you.
      • 2 months ago Playwell Bricks Level 11 Designed this MOC
        It was just copying the file over with the old name, I had to rename it to upload the new one. Thanks for pointing that out!

    Hey, can the 3300 in dbg (99x) be substituded?
    Its impossible to get that amount.
    Cheers stefan.....btw awesome moc
    • 2 months, 2 weeks ago Playwell Bricks Level 11 Designed this MOC
      Hi Stefan

      They form the ridge cap on the roofs, so if you were going to substitute them I would use 30 degree cheese slopes (85984) and (54200), you will need enough to cover both sides of the slope obviously.

      Feel free to make whatever changes you need to make the build more affordable. This originally was a personal  project, and not much attention was paid to the cost of parts, so if you need to make substitutions then go for it :)

      Thanks
      Jason
