This is a modular abortion option 21324-1 – 123 Sesame Street  It has a width of 16 studs and is suitable for the format of modular buildings. To assemble, you will only need the parts of the original set. The model consists of two buildings. There is a small shop on the left, a residential building on the right. The house has a staircase to the second floor, a room with a bed, an armchair and a TV, and a bathroom with a toilet. On the roof there is a garden with a tree and a flower bed. The roof is removable, like all modular buildings. You can get to the lower floor by removing the back wall.
Unfortunately, the stickers are not shown on the renderers, but they are the same as in the original set.
