5 key facts about this project
01
Constructed with bamboo rods treated with Borax for enhanced durability.
02
Utilizes Geo-Green crete, eliminating Portland-based cement for sustainability.
03
Modular design allows for flexible adaptations to resident needs.
04

05
Features integrated green spaces for ecological benefits and aesthetic appeal.

The "Living Stairs" project is located in an urban area of Melbourne, designed to fulfill the needs of modern residents. It focuses on modular housing that offers flexibility and personalization. Each living space can be adjusted based on the preferences of its occupants. The design resembles the shape of stairs, promoting a growth pattern that extends both in width and height. It brings together shared and private spaces to create a cohesive living environment.

Material Selection

Bamboo is used prominently in the walls of the first floor. The bamboo rods measure 14-16 cm in diameter and are treated with 1.5% Borax solution for added strength. This material choice is significant because it provides durability while supporting sustainable building practices. Bamboo is lightweight and renews quickly, making it a responsible choice for construction.



On the upper levels, Geo-Green crete blocks are used. These blocks do not contain Portland-based cement and are made from post-industrial waste along with aluminosilicate materials. This approach reduces the environmental impact of the building and ensures that it is structurally sound. Utilizing Eco-Green crete highlights a forward-thinking method in environmentally friendly architecture.



Modular Configurations

Module 1 features a compact design that serves multiple purposes within a space of 37 m². It includes a kitchen, a living room, a bedroom, and a bathroom, all laid out to maximize utility. A notable aspect of this module is the staircase designed to look like benches. This feature encourages social interaction and connects the module to the street, while also incorporating greenery that enhances the overall appeal.



Module 2 builds on the concept with a two-story living area that offers flexible arrangements. Residents can configure it for social spaces on the first floor and private areas above or choose the opposite layout. This versatility caters to different lifestyles, allowing a community feel while still providing personal space.



The overall design invites engagement between residents and their environment. The stair-like shape encourages movement and connection, supported by integrated green spaces that enrich the living experience. Each element contributes to an urban setting that balances community and privacy effectively.

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.
