5 key facts about this project
01

02
Features four distinct monolithic forms inspired by volcanic landscapes.
03

04

05
Includes an adaptable outdoor terrace for varied seasonal use.

The visitor center is located in an area characterized by black lava fields, designed to closely connect with its surroundings. The building takes the form of large boulders, reflecting the geological features of the landscape. This approach creates a space that encourages visitors to appreciate the environment. It serves not only as a location for exploration but also as a platform for cultural activities and learning.

Site Integration

The structure features four prominent monolithic forms inspired by volcanic formations. The vertical lines on the surfaces are similar to the natural patterns of water flow on the slopes of the nearby volcano. This design element enhances the overall connection to the landscape and highlights the beauty of the natural environment.

Spatial Organization

The interior layout consists of multiple pathways and access points, allowing visitors to move easily between different areas. These spaces are designed to be connected, promoting exploration and social interaction. An upper outdoor terrace can be transformed into a winter garden. This terrace also provides various routes for reaching different levels of the building, whether by stairs or elevator.

Sustainability and Materiality

Sustainability plays a significant role in the design and construction of the visitor center. Locally sourced materials are used to reduce environmental impact while ensuring a cohesive look. The building incorporates double slab walls to respond to local conditions. An ecological mortar made from local sand and gravel mixed with a clear resin is applied to the exterior. These choices help reinforce the building’s bond with the landscape while maintaining durability.

Cultural Engagement

Visitors are immersed in the volcanic landscape as they explore the interior. Cultural spaces are strategically located at the base of the monoliths, allowing guests to engage with the scale and texture of the surrounding geology. A summit skylight is an important feature of the design, letting in natural light and enhancing the connection between the inside and outside. This design choice enriches the visitor experience while keeping the focus on the unique environment.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
