Modular Housing Architecture: Hexagonal Affordable Housing (HAH)

A forward-thinking approach to urban dwelling, the Hexagonal Affordable Housing (HAH) project explores the dynamic potential of modular housing architecture to address the contemporary housing crisis. This Honorable Mention entry of the Plugin Housing Challenge 2020, conceptualized by Andrea Wan, Anurag Jadhav, Katelyn Anderson, and William Ingram, presents a bold vision of flexibility, sustainability, and spatial efficiency.

Dynamic and Modular by Design

HAH reimagines the mid-rise urban residential block as a modular, kinetic system. The design consists of 84 trapezoidal housing cells that attach to a structural grid and are capable of sliding in and outsimilar to drawers in a dresser. This movement allows for cantilevering elements, dynamic spatial reconfigurations, and maximum daylight exposure. The result is a living building that evolves with its inhabitants and their needs.

Rooted in the philosophies of the Japanese shinchintaisha (metabolist) movement, HAH applies a contemporary technological lens to the idea of adaptable architecture. By utilizing a scalable grid structure, the project can cater to a wide range of urban densities, site constraints, and community demographics.

Smart Energy Efficiency

HAH integrates photovoltaic cells across the façade to generate renewable energy. Each modular unit is designed to slide in and out, adjusting its position to expose photovoltaic surfaces to optimal sunlight throughout the day. This self-orienting mechanism increases solar efficiency while also powering the kinetic movement of the units. The energy harvested directly contributes to a lower operational cost and supports a net-zero approach.

Lighting Inspired by Culture and Technology

The lighting strategy of HAH is inspired by the Chinese idiom zuo bi tou guang, the story of a scholar who carved a hole in a wall to study using a neighbor's light. Translating this narrative into a design feature, the project introduces shared triangular lightboxes powered by solar panels. Translucent panels resembling Japanese washi paper diffuse natural light into adjacent units, maximizing illumination and reducing electricity consumption. Smart sensors control interior and exterior lighting, adapting to daylight conditions and user needs.

Site-Specific Urban Integration

Though conceptual, the project is imagined within a typical San Francisco urban block. The site layout considers the challenges of dense metropolitan environments—such as solar access, scale, and topographic complexity. HAH responds by creating a central plaza with concrete paving and tree-lined seating areas. The absence of lawns is intentional, conserving water and reinforcing the project's environmental ethos.

Interior Design for Young Urbanites

Each double-occupancy unit spans 70 square meters and is tailored for young professionals, students, or first-time cohabiting couples. The interiors are open and adaptable, featuring a loft bed, home office, fully-equipped kitchen, and lounge. High ceilings and large window panels create a bright, spacious atmosphere. The reduced use of walls allows for fluid space configurations, ideal for evolving urban lifestyles.

Shaping the Future of Modular Housing Architecture

Hexagonal Affordable Housing (HAH) stands as a compelling prototype of how modular housing architecture can intersect with sustainability, kinetic systems, and cultural storytelling. It champions a modular urban future—smart, adaptable, and deeply human-centric.
