LEGO Modular Buildings custom inverted corner

Most of the LEGO Modular Buildings are made in such a way that they can be lined up and connected in a row. This makes them especially suitable for shelf displays. There are also some corner buildings (#10182 LEGO Creator Cafe Corner from 2007, #10211 LEGO Creator Grand Emporium from 2010, #10232 LEGO Creator Palace Cinema from 2013, #10251 LEGO Creator Brick Bank from 2016, and #10260 LEGO Creator Downtown Diner from 2018) that can be used to finish the corners of a row of buildings, or to turn corners to build deeper displays with entire city blocks. In other words, there are lots of ways to display them! 🙂

While the LEGO Modular Buildings can be configured in a number of different ways, there is one type of display situation that LEGO designers haven’t addressed as of yet; inverted corners. In other words, if you have a shelf system on two connecting walls creating a 90-degree angle, none of the official LEGO Modular Buildings can fill the corner of the L-shape.

LEGO fans have been addressing this situation be either leaving a gap between the two sides of the L, pretending there is a street or alleyway going through, or creating some type of dummy building to fill up the corner without being in the way of the various extensions (roofs, canopies, windows, doorways, etc.) of the buildings closest to the inverted corner.

The #10255 LEGO Creator Assembly Square released in 2017 shows two examples of how inverted corners can be handled. The set features three distinct buildings next to each other. The sand-green building in the middle sits further back than the two surrounding buildings, creating two inverted corners. Between the sand-blue building on the left and the building in the middle, there is a gap with an alleyway. The other side of the sand-green building is pushed against the building on the right creating an L-shaped construction. This second type of solution is what LEGO fans have been looking for but in a larger scale to be able to turn corners.

Since there is no official LEGO Modular Building to make a 90-degree inverted turn, LEGO fans have to design and build their own structures to create a smooth transition from one side of the street to the other. As LEGO Modular Buildings are quite large and complex, designing such a transitional building can be a bit intimidating both in terms of designing them and the cost of getting the necessary parts.

Usually the cheapest way to create a custom LEGO Modular Building is to modify one of the official sets in the collection. They give you plenty of pieces to work with, and you can copy many of the design solutions already used in the set. Still, designing a custom building can still be a daunting task, especially when working on an idea that you can’t find an example for in an official set. However, it is likely that other LEGO fans have grappled with the same problem, and may have already come up with a solution.

To address the issue of turning at an inverted corner with the LEGO Modular Buildings, LEGO fan Huaojozu came up with an elegant solution. Interestingly, he used the #10255 LEGO Creator Assembly Square as the base model for the alternate structure, even though his custom building looks very different from the official set. Most importantly, Huaojozu shares detailed pictures, as well as downloadable instructions at Rebrickable.com. (The instructions are a little pricey, but you may not even need them once you study the pictures.)

Hoaojozu didn’t just successfully turned the corner with his custom building, but he also fully designed and furnished it inside. The structure is mainly a music club, with the first floor housing the stage and dance floor. There is also a jukebox for when there’s no live performance, and a couple of tables for drinks. There is a bar on the second floor, and a fully furnished apartment on the third floor. Only pieces from the #10255 LEGO Creator Assembly Square were used, so no extra parts are needed. If you are interested to download the instructions, there are available in two formats; either as a LEGO Digital Designer file or as a PDF. You can download them here. Hoaojozu designed a number of alternate models for LEGO Modular Buildings, so you might want to check those out as well.

It is possible that in the future LEGO will release a set that will allow us to easily fill an inverted corner in a LEGO Modular Buildings display, but in the meantime, we can create our own solutions, or use the solutions provided by other LEGO fans. Rebrickable.com is a great resource for finding alternate builds for official LEGO sets, and for the current selection of LEGO Modular Buildings, visit the LEGO Creator section of the Online LEGO Shop.

    I have the modulars on a corner shelf, and I just have a road going on between. I like my setup, but having an inverted corner building is a good idea too. Do we know yet what is the new modular? Isn’t it supposed to be announced by now?

    • admin November 30, 2018, 1:12 PM

      The announcement is coming soon. Just a few more sleeps. 😉

      • Rob November 30, 2018, 6:37 PM

        “Just one more sleep until Christmas”. Reminded me of The Muppet Christmas Carol. 🙂

        • admin November 30, 2018, 10:15 PM

          Well, yeah, it’s the holiday season! 😀

  • DavidH November 30, 2018, 11:19 AM

    Well done. Lego will probably never release an inverted corner building because it would look too obscure by itself. So custom solutions are always interesting. The Detective’s Office also has a little bit of inverted corner, but it would require rebuilding to actually use it as a corner.

    • admin November 30, 2018, 1:14 PM

      Good points. Yeah, if you have a corner shelf, you are going to have to find your own solution. There are actually a number of example by LEGO fans, either redesigning an official set, or building their own.

  • sammy November 30, 2018, 12:05 PM

    This is a great idea. And I like that no extra parts are needed. I would do some of the interior differently, but that’s just a minor detail.

  • Håkan November 30, 2018, 12:49 PM

    Hmm, this looks a bit weird to me. Is this that common in real-life architecture? Or am I just too accustomed to urban block and triangle-based city planning?

    • Håkan November 30, 2018, 12:59 PM

      Or is this a practical solution for builders who’d place their modulars on shelves inside a room with corners?

      But then I’d guess you could just leave some space in the corner, anyway…

    • admin November 30, 2018, 1:10 PM

      In real life, such a design would usually be used to wrap around a plaza or courtyard, like we see in the Assembly Square. It is basically the internal side of the city block you are talking about. So, it’s not entirely unheard of. LEGO fans are usually not building full city blocks, but display the Modulars in a row on a shelf. If the shelf wraps around the corner of the room, which is common, you have to leave a gap at the corner for the layout to make sense. You could technically put in one of the Modular corner buildings facing backwards to connect the two sides of the “L”, however if the shelf is against the wall (like most shelves are), you are wasting an entire building that would never be seen from the front. An inverted corner Modular solves this dilemma by connecting the two sides and looking good from the front. 🙂

      • Håkan November 30, 2018, 1:32 PM

        Yeah, I figured there’d be inner yards or something, although in my experience, these yards are mostly private yards, not common locations with coffee shops etc.

        But I begin to understand that display issue, now.

        • admin November 30, 2018, 2:10 PM

          I guess it just depends on the area. In Chicago, plazas and courtyards are common both amongst older and newer buildings. Some of them are private, as you said, but most of them are public places. Courtyards are also popular in Arizona for private residences. Here, in Florida, where tall city buildings are not so common (except in Miami, Orlando and Jacksonville), courtyards are mostly used as an interesting architectural style in shopping centers and malls. They kind of have a cozy feeling, so they are perfect places for little shops, restaurants, and cafes. Very much like in the Assembly Square set. 🙂

    I’ve tried many time to make a moc modular building but, it always works or looks better as a half build ( the front is complete but, you turn it around and there’s the inside . No back to it). I made a post office and a small fire station. Oh, and a police station.

    • Håkan November 30, 2018, 7:04 PM

      I’m not sure if I have ever seen the back of a real modular house. What do they tend to look like?

      • admin November 30, 2018, 10:20 PM

        Most of them are pretty plain with simpler windows and doors, fire escapes, etc. But some of them are actually really nicely built up at the back as well. Most notably the Parisian Restaurant and the Detective’s Office looks very nice from the back. If you watch JANGBRiCKS’ reviews, he turns the buildings all around so you can see them from all sides. You can also see the backs of a whole Modular Building block from this video (although some of the buildings are extended): https://youtu.be/FuLmscBiYAA

    • admin November 30, 2018, 10:14 PM

      You mean no back wall? That’s more of the style of the LEGO City buildings. Very useful for playing inside. 🙂

  • Legostuff14 November 30, 2018, 7:28 PM

    Probably the same as the modular buildings. They may have a balcony ,Fire Escape and a place to create a backyard. As much as the modular buildings are all built up , there is really nothing in the back . The design isn’t as detailed as the front. The other problem is that it’s hard for us “big figs ” hands / or fingers to be able to move or display the mini figures inside the modular buildings. The rooms are to small.😞

  • Alison December 1, 2018, 2:47 AM

    I don’t have the pleasure of a large shelf on which to display modular buildings, but if I did, I would probably put a little garden with a large tree and paths. Even better would be to have a very shallow building facade in front of the wall.

    • admin December 1, 2018, 10:12 AM

      Those are great options too! 😀

      • Håkan December 1, 2018, 10:53 AM

        Sounds serene. Almost Zen-like…

  • Håkan December 3, 2018, 9:07 AM

    And now I see that the new modular has been revealed. Unfortunately, there seems to be very few parts in Vibrant Coral…

    • admin December 3, 2018, 10:52 AM

      My guess is that it will be included in later sets. It takes a while until a new color gets integrated into different themes.
