Innovative storage solutions, children's toys and a music amplifier are among the designs made from repurposed cardboard that have been shortlisted in Dezeen and Samsung's Out of the Box Competition.

The contest sought innovative designs for the home that can be made by repurposing corrugated-cardboard packaging, to encourage users to creatively reuse the box their television is shipped in rather than throwing it away.

With many countries in lockdown, the competition provided people with a creative challenge they could undertake at home. Interest in the competition was extremely high and we received over 1,500 entries from more than 80 different countries around the world.

In total 15 designs have been selected for the shortlist, which are set out below in the order in which the entries were received. From this shortlist, the jury will select five finalists, which will be announced in August, before the overall winner is announced in September.

The winner will receive a top prize of $10,000, the runner up will receive $5,000 and third place will receive $3,000. The fourth- and fifth-placed entrants will receive $1,000 each.

The competition was inspired by Samsung's Eco-Package concept, which aims to reduce waste by providing customers with a way to repurpose its television packaging into new household items.

Each design has been built using Eco-Packages for Samsung's The Sero, The Serif and The Frame televisions. We have published photographs of each of these builds alongside a lifestyle image featuring a prototype of the design made by the entrant at their home.

Studio photography is by Benjamin Swanson with set design by Jam Studios and retouching by The Wizard Retouch.

Here are the shortlisted designs:

Gio container by Francesco Pierazzi Architects
London, UK

Gio is a faceted, multi-functional container comprising two tapered cylindrical volumes of different sizes. It can be used as a plant pot, a small side table or a storage container.

Each volume is assembled from 12 corrugated-cardboard panels, which the user can bind together with string or ribbon to provide subtle decoration.

"Multiple elements can connect the pieces depending on what may be available," said Francesco Pierazzi Architects. "String, ribbon, cable ties, or any combination of those will ensure an outcome that is unique to one's household."

The design has been built using The Sero Eco-Package.

Toolbox by Joseph I'Anson
London, UK

Joseph I'Anson has designed a simple toolbox, which could also be used to store tools, stationery, plants or food. The design comprises a series of flat corrugated-cardboard panels, which lock together without the need for any glue or tape.

"With use, the structure becomes stronger," I'Anson explained. "The upwards force of the object being lifted, and the downwards force of the contents, push the grooves further into each other.

It features large openings, designed for people that want to show off their collection of sneakers, which are stacked vertically to ensure they take up the minimum amount of floor space.

"The sneaker rack is inspired by sneaker culture where collectors appreciate sneakers as a form of art," said Jin Yoong. "Being made of cardboard, it replicates the feeling of unboxing a new pair of sneakers."

The design has been repurposed from The Frame Eco-Package.

"Kibe" means "stairs" in Georgian, which is Berdzenishvili's native language.

"The shape of Kibe is, as the name reveals, formed as stairs," said Berdzenishvili. "The aim was to recreate the functional features of stairs and bring it into interior space, as an independent sculptural object."

It has been built using The Serif Eco-Package.

Twist basket by Akhil Kumar
Mumbai, India

Twist by Akhil Kumar is a basket that can be used to store a variety of different objects. It is constructed from just two sheets of corrugated cardboard – one for the base and one for the sides – to minimise the amount of cutting and glueing required.

Although it is very simple, by folding along diagonal lines, users are able to create an interesting and visually appealing faceted shape.

"My idea of Twist emerged from the desire to create a product anyone could use in their home in multiple ways," said Kumar. "I believe minimising the effort required to build it is a way to encourage people to recreate and repurpose the cardboard boxes."

It has been built using a The Sero Eco-Package.

Kinoko Table by Georgia Kasmin and Frank Lin
London, UK

Blast Off Club House by Olga Tesler
Los Angeles, USA

Olga Tesler has created a toy spaceship that kids can crawl inside and use as a fort.

Star- and moon-shaped cutouts in the roof let light inside during the day. At night, the user can place a light inside to cast patterns onto the ceiling.

"The Blast Off Club House has been designed to look like a spaceship and feel like a little personal hideaway," said Tesler. "The design is geared towards kids of various ages. It's stable and is equipped with numerous openings that can be used as windows and as access for light."

Amplephone amplifier by Pushan Panda
San Francisco, USA

Pushan Panda has created a cardboard horn that amplifies music from a mobile phone. The design is constructed from a series of flat corrugated-cardboard panels, which are scored and opened out to create a horn shape reminiscent of the amplifiers found on gramophones.

"When the first gramophone was invented in 1898, its horn amplified the mechanical oscillations of a pin running along a disc to produce sounds that could be heard by the human ear," said Panda.

"My proposal matches this history with modern technology. With a single sheet of cardboard, I created an amplifier that turns sounds from a phone into music that can fill a room."

The amplifier has been built using The Sero Eco-Package.

The Rider rocking horse by André Cardoso
Braga, Portugal

André Cardoso has created a rocking horse for kids made from the box of a Samsung The Serif television.

It is assembled from a series of folded corrugated-cardboard panels, which are orientated so that the graphic representation of The Serif TV printed on the outside of the box forms a saddle.

"The main idea comes from the central graphic element on the packaging: a TV icon that resembles a horse saddle," said Cardoso. "It becomes so the starting point to design a simple and archetypal horse silhouette, carefully placed around the saddle."

The Soban tables by Kiyong Lee and Yejin Kim of beFormative
Seoul, South Korea

Kiyong Lee and Yejin Kim of design studio beFormative have created a pair of Soban tables – low, tray-like tables that are used in South Korea for dining and carrying food – in two different sizes.

It comprises a series of triangular modules, which can be arranged in a number of different ways – either to show off the objects it contains, or to hide them away – to create a table, sideboard or shelving.

"It's perfect for houses of all shapes and sizes, and can be easily adapted giving endless possibilities to a cardboard box that would usually be discarded," said Whitelow.

The modular system is designed to be built from a The Frame Eco-Package.

Postcard Planter Series by Koji Yamaura
Mountainview, USA

Koji Yamaura's Postcard Planters are a series of interior objects that allow the user to "plant" photographs or postcards and display them in their home.

There are three different versions of the planters – one that's designed to be wall-mounted, one that's floor-standing and one for tabletops. Each one comprises strips of folded corrugated cardboard, which are arranged to create small gaps for photos or postcards to be inserted.

"Spending more time at home due to Covid-19, I came up with this idea whilst looking back at my collection of postcards from art museums and exhibitions," said Yamaura. "I wondered if there was a way to enjoy and beautifully display my favourite postcards and memorable photos."

The design has been built using The Serif Eco-Package.
