A place in the city that keeps your stuff.


Madrid counts with more than 3 million people and it welcomes more than 9 million visitors every year.
With these increasing numbers, the city tries to evolve towards more sustainable urban patterns and mark its way to a smart city. With this objective in mind, the PMUS (Plan de Movilidad Urbana Sostenible) is born in 2008. This plan includes improving public transportation, bicycles, and pedestrians’ life. Nowadays new sharing mobility infrastructures have been already implemented: BiciMad, Cargo and Emov.

In this sharing systems boom, I found one missing piece: there was no infrastructure thought for managing people’s hand-luggage.


This project is targeted for the urban and young people. Given the technologic changes the city has gone through, these groups of users are undoubtedly more open-minded than the rest of the citizens; people that are used to sharing the public transportation means, bikes or other alternative ways. I am talking about people who spend most of their time on the street, wandering from one place to another, sometimes without even passing by their homes. Besides, tourists already represent an important role in these services and they may be the ones that could make it viable.


As I was analyzing user journey maps I reached the conclusion that people spend most of their time in the city, but they don’t actually have a place to leave their belongings beyond their homes or cars.

Field research indicated there were lockers in the city such as in supermarkets, gyms, trains or bus stations, yet the lack of public spaces and their tourist-wise nature make them highly inaccessible for everyday people. In general, these services aren’t well known or they’re considered expensive. I found them to be technologically outdated and inaccessible.

Another kind of lockers was appearing in the city such as post boxes, for receiving private packages from companies like Amazon or Correos. These recently developed services aren’t conceived for personal use, however, they show innovative and technological systems to be possible.


The solution proposed consists in a system that will bring locker services to people. In order to make them accessible to all users at any time, an urban furniture infrastructure could be implemented. This modular structure could also be located in public spaces such as stations or shopping malls.


It can be done through a reliable and trustful service, but first, the service must be known. This implies the creation of an approaching and familiar brand to the user.

The brand name «Meloguardas», which in Spanish means «Keep it for me?», explains the purpose of the service by itself while it uses an easy going and friendly language.

The form of the logotype proposal follows the modularity and flexibility standards of the service. Moreover, the square shape can be used as a landmark for people to identify locker stops in the city. The colors of the brand remind us of their sister lockers around train stations in the city, however, the intention behind this choice was not left to chance. It is well known that blue transmits a cool and calming vibe that shows aptitude whereas green is an emotionally positive color that’s more related to sustainability and safety. Both colors are bright and can easily get stamped in your memory, at the same time they can be quickly spotted from the distance.


As the need to control and manage this service rises, the mobile app solution will play a truly important role in delivering a complete experience to its users.
While it mainly functions as an activation key, it also serves as locker tracker and a payment tool.

The interface has been conceived to be as simple as the system it represents. As it’s going to be used on the street, it was meant to be designed in bright colors and big buttons, making the user experience easier. All options are available on the main page for the users to have everything they need at hand.

The mobile app prototype above shows different screen levels (map, locker stop, individual locker).


Along the process, concept brainstorming exercises, journey maps and interviews with potential users were carried out as a need for genuine feedback to develop the idea.
As I was following a design thinking methodology, I needed prototypes that could bring the service to life. That’s the reason why the previous prototypes were designed.
Some of the tools I used were Illustrator for graphics proposals, 3D Max and photoshop for scenes representations.

This is part of the Final Project Degree presented at Complutense University in 2015. It was aimed to show the abilities learned throughout the degree, such as Product, New Media and Graphic Design subjects.
