The building's spiral rotating floorplate and vertically stacked louvers create a unique façade that prioritizes both individual privacy and efficient space utilization, providing affordable housing solutions in an urban landscape.
5 key facts about this project
01
The building utilizes a spiral rotating floorplate to enhance spatial efficiency.
02
Vertically stacked louvers allow for personalization while ensuring privacy.
03
The design incorporates under-utilized pedestrian medians as the site location.
04
A mixed leasing strategy balances long-term and short-term rental units.
05
The architectural form minimizes disruption to existing urban foot traffic.

The project tackles the urgent issue of affordable housing in urban areas, particularly in Paris, where increasing rent prices present a significant challenge. The design centers on the use of super-efficient core units and minimal area residential spaces. This approach aims to create a solution that optimizes space utilization while supporting a mixed leasing strategy that includes both long-term and short-term rentals.

Design Concept

The concept proposes a new typology that embraces short-term leasing as a beneficial financial model. Most of the residential units are designated for long-term tenants, with a portion reserved for short-term rentals through platforms like Airbnb. This mix is intended to establish a sustainable economic framework where income from short-term leases can support long-term housing stability.

Site Selection

The project strategically identifies under-utilized pedestrian medians as its site. This choice allows for minimal ground floor space use, preserving important pedestrian pathways. By avoiding disruption to foot traffic, the design contributes to the overall urban environment. The building features a spiral rotating floorplate that deviates from the conventional stacked layouts, enhancing both efficiency and functionality of the living spaces.

Architectural Features

Each residential unit includes an efficient apartment core equipped with a kitchen and bathroom. This design effectively addresses the challenge of limited floor area by maximizing vertical space. A key element of the design is the vertically stacked louvers, which allow residents to personalize their spaces. This feature results in a façade that maintains privacy while also showcasing individual styles within the overall architectural structure.

Façade and Interaction

The building's façade is designed to be clean and unobtrusive, helping create a cohesive urban experience. This simplicity fosters a connection between the individual apartments and the surrounding community. As residents personalize their living quarters, the interplay between their belongings and the building contributes to a lively architectural character. Each unit reflects personal identity while enhancing the collective nature of the space.

The integration of thoughtful design and effective use of space creates a practical response to the pressing need for affordable housing solutions. The project offers residents a meaningful opportunity to engage with their environment while addressing significant urban challenges.

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.
