Visitors can experience a variety of activities during their visit, including physically and digitally building with Lego bricks, programming robots and animating models.

The building incorporates 21 staggered blocks that resemble Lego bricks, with nine roof terraces containing children's play areas.

In his opening speech, Kjeld Kirk Kristiansen, the majority owner of The Lego Group described his vision for the building.

[1]My vision with this house is to create the ultimate Lego experience which truly unfolds the endless possibilities there are with our bricks and our Lego system of play and have all these experiences in one house, the home of the brick.In addition to its concept as a visitor centre, Lego House was also created to offer a communal urban space to the local community, due to its central location in Billund, with many areas of the complex, such as the roof terraces, having been designed to be entirely free to enter.

The building consists of a series of interconnecting modular spaces, which house the exhibition and experience areas for visitors.

Ingels explained how the proportions of the Lego brick provide a golden ratio in architecture and have therefore been used throughout the entire building.

White ceramic tiles were used on the external façade to reflect the light and create a subdued form, in an effort to avoid overloading Billund with too much colour.

In contrast to its subtle appearance from the ground, visitors arriving by air are able to get an aerial view of the primary colours on the top of the building.

[9] The building was constructed on the former site of Billund town hall, just a few metres from the location of the workshop where the company began in 1932.

The site was chosen not only for historical reasons, but also to revitalise the town centre and to transform Billund into the "creative world capital of children".

[12] Lego House was originally set to open in 2016, but was delayed by a year, due to the technical challenge of implementing a design without columns.

The Robo Lab also provides the opportunity to direct a robot by using coding commands to build a number of steps.

The Green Zone includes the Story Lab, a 60-minute activity, which involves writing and directing a stop-motion movie.

The zone also includes the Art Machine, an experimental 60 minute activity aimed at 4th to 6th grade learners, which involves the use of Lego bricks and a pen and the Creative Lab.

The Tree of Creativity spans several floors and can be viewed from a variety of levels and angles by using the spiral stair that wraps around the structure.

Stuart Harris, Senior Designer at Lego House said, "We wanted to create some unique and breathtakingly iconic models.

At the same time we wanted to create opportunities within the house to showcase the incredible creativity and diversity of the AFOL community".

The initial entry point into the building is known as Lego Square and features several brick built displays and a signpost, which directs visitors to the main areas of the complex.

The Mini Chef restaurant offers visitors a unique experience that presents menu items coded to correspond with Lego bricks, which are used to build the meal and scanned to send the order to the kitchen.

[25] Lego House, along with Bjarke Ingels Group, also won the INSIDE World Festival of Interiors Awards in 2018 in the Civic, Culture and Transport category.

[31] A documentary entitled Lego House-Home of the Brick won prizes in two categories in the Cannes Corporate Media and TV Awards 2018.

[32] The Fish Designer activity, located in the Lego House Yellow Zone achieved a Visual Media Experience Award from SXSW Innovation Awards for achieving, "content creation and delivery that moves beyond passive viewership by providing a more immersive and engaging entertainment experience".
