When we reviewed the #21324 LEGO Ideas 123 Sesame Street set, we mentioned how the set is a perfect candidate to transform into a LEGO Modular Building. The two buildings feature highly detailed facades and interiors, but they aren’t enclosed structures all the way around like the LEGO Modular Buildings. Thus, a bit of redesigning and rebuilding is needed to make the set compatible with the Modulars.

If you would like to fully enclose the buildings yourself but need some help, Rebrickable.com has several examples with downloadable parts-lists and instructions. Below, I will show you some of my favorites.

The LEGO Sesame Street Corner by lawis repositions Hooper’s Store next to 123 Sesame Street, and thus creating a corner layout with sidewalks at the front and on the left. I really like the little alleys this layout creates at the side and the back. You will also notice that the 123 Sesame Street Building has been widened with an extra column of windows.

Please note that the original set has several rare and hard-to-find parts, so the easiest way to build this version is to purchase two copies of the #21324 LEGO Ideas 123 Sesame Street set. There are a few other pieces needed to make the building complete, but their color are size are usually not essential, and you can use whatever you have available. Mainly, you will need a 32×32 baseplate in any color, and dark-gray and a few light-gray tiles for the sidewalks to match the Modulars. More pictures, a full parts list, downloadable instructions (cost $9.90), and helpful notes from the creator are available at the following Rebrickable page.

The LEGO Sesame Street Modular Building by Harry_HAN is another great alternative. This version leaves some sidewalks on all sides, so it is more suitable as a standalone block in your city, rather than next to the other Modular Buildings. This is also a great option if you don’t want to add it to the Modulars, but you would like to make your Sesame Street set more finished-looking. Downloadable instructions for this version is $12, which is a little steep, so study the pictures carefully to make sure this is what you want. Available at the following Rebrickable page.

The LEGO Sesame Street Modular Building by benbuildslego rebuilds the main building on a 16×32 baseplate, making it a narrow Modular. Hooper’s Store is not used in this configuration. And no extra pieces are needed besides a baseplate and a couple of 1×2 Technic bricks with hole for connecting the building to other Modulars.

This is an especially attractive option if you don’t really care for Sesame Street, but you like the building and want to add it to your LEGO Modular Building layout. As you can see in the pictures, it really nicely fits in between the other Modulars. The downloadable Building instructions are $9.99 and can be downloaded at the following Rebrickable page.

The next version of Sesame Street is a little different, but I thought that some of you might like it as an attractive and compact display option. It is called the LEGO Sesame Street Photo Frame by beewiks.

For this version, no extra parts are required. You simply purchase one copy of the #21324 LEGO Ideas 123 Sesame Street, rebuild it according to the downloadable instructions, place it in an IKEA Sannahed 25×25 cm display frame, and hang it on the wall. (The blue sky background is a picture only, which is included with the downloadable instructions.) Instructions are $5, and available at the following Rebrickable page. And if you are interested to place some other sets into photo frames, beewiks has several other models converted in a similar way.
