Optimizing Natural Light Through Petal-Form Structures and Thermal Mass Techniques

Project in-detail

Utilizing a petal-form structure and advanced thermal mass techniques, the design maximizes natural light and airflow, creating an adaptable residential space suited for the challenges of a desert environment.
5 key facts about this project
01
Utilizes a solar chimney for natural ventilation, reducing reliance on mechanical cooling.
02
Incorporates petal-shaped structures that enhance shade and aesthetic appeal.
03
Employs thermal mass through natural stone to regulate indoor temperatures.
04
Features an open-plan layout that promotes flexibility in space usage.
05
Integrates sustainable landscaping techniques for water conservation in a desert environment.

### Overview

Located near Dubai, the Crepuscular House is designed to harmonize living spaces with the distinct climatic conditions of a desert environment. The intent of the project is to create a sustainable and adaptable dwelling that maximizes natural light while minimizing energy consumption. The architectural concept, "Reinscribing Light," emphasizes a flexible spatial arrangement that responds dynamically to varying light conditions throughout the day.

### Spatial Configuration and Materiality

The design integrates a modular approach to space, where social areas, including the living room, kitchen, and dining areas, are interconnected to foster interaction among occupants. The exterior features sculptural forms that evoke organic shapes, establishing a visual connection with the surrounding desert landscape. Key materials include concrete for structural support, plywood for interior warmth, and extensive glass to enhance natural light and spatial openness. Additionally, natural stone is used to provide thermal mass, contributing to passive cooling strategies.

### Sustainability and Environmental Integration

The project employs advanced passive cooling techniques, notably through a solar chimney that promotes natural airflow and reduces reliance on mechanical cooling systems. Adaptive shading elements are designed to manage heat gain while ensuring visual comfort, creating a symbiotic relationship between architecture and environment. Innovative landscaping and water management systems are incorporated to promote water conservation, reflecting a commitment to sustainable practices appropriate for arid climates. Such design elements collectively illustrate how the Crepuscular House addresses ecological considerations while remaining functional and responsive to the needs of its inhabitants.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
