Lego Modular Houses - Challenges

Challenges

A challenge faced by the designers of these sets is that they are not able to work with the full palette of Lego bricks and colors ever produced when designing. Instead they are limited to the bricks and colors currently in production by Lego at the time of the product design. As an example, for Café Corner, the designer wanted to include a bicycle piece in the set, but at the time, the machine that made bicycle pieces was broken. It had to be fixed in order for the designer to be able to include the piece in his design. With Market Street, the fan designer was limited to only the bricks and color combinations available as 'active components,' meaning bricks that were already in production. No new bricks could be introduced.

There have been scheduling challenges faced in the design of the Modular Houses sets. For the Green Grocer set, the designer believed that the set could have benefited from another design iteration before release. The detailed nature of these sets requires a greater amount of design time than a normal Lego set. It is expected that future sets in the series will not suffer from such schedule pressures.

During the design of Café Corner (and presumably with the other sets in the series), the designer had to work closely with the building instructions team due to some of the "unorthodox techniques" that he used "which have not been tried before in official Lego sets."

The reason interiors were not included in the first two models in the series, Café Corner and Market Street, was because they could not be seen in the pictures included on the packaging. Once the success of Modular Buildings sets had been proven with these first two sets, for the third set, Green Grocer, the designer was allowed to include interior details in each of the floors. As a result, many of the interior details of later sets, such Green Grocer, are not visible on the box and are only discovered while building the set. However, the boxes of each set feature some of the interior details such as the escalators inside Grand Emporium.
