Pyramid-Shaped Dwelling Crafted From Recycled Plastics and Concrete Emphasizing Modular Living

Project in-detail

Constructed with recycled plastics and concrete, this pyramid-shaped dwelling integrates modular design for adaptive living in a sustainable environment.
5 key facts about this project
01
Constructed entirely from recycled plastics, reducing environmental impact.
02
Pyramid shape optimizes natural ventilation and rainwater management.
03
Modular layout allows for flexible reconfiguration of living spaces.
04
Pre-fabricated components streamline assembly and minimize on-site waste.
05
Integration of communal and private areas fosters a sense of community.

### Overview and Concept

The Stack House is designed as a sustainable residential structure that employs innovative construction methods with a focus on ecological integrity. Located in a landscape that supports natural integration, this project utilizes modular construction techniques that allow for adaptability and efficient material use. The design emphasizes the principles of sustainable living through carefully considered material selection and spatial organization.

### Architectural Configuration and Functionality

The Stack House features a distinctive pyramid shape, which serves significant functional purposes. The sloped roof aids in rainwater management by efficiently directing runoff for potential harvest and promotes natural ventilation, enhancing indoor air quality. The building’s geometry incorporates a facade with a mix of triangular elements and perforated sections, optimizing both aesthetic appeal and functional light control while maintaining privacy.

The interior is organized into flexible modules that cater to diverse living arrangements, allowing occupants to adapt spaces as their needs evolve. Key areas include a central living space designed for interaction, private sleeping and study modules that ensure seclusion, and multi-functional zones that encourage community engagement. Unique design elements, such as suspended netting in high-ceiling spaces, provide innovative lounging areas while optimizing spatial utility through built-in storage solutions.

### Material Selection and Sustainability Practices

The project prioritizes sustainability by utilizing a variety of recycled and locally sourced materials. Key components include:

- **Recycled Plastics**: Shredded plastics are transformed into structural elements, addressing waste reduction and providing a sustainable material narrative.
- **Concrete**: Selected for its structural integrity, this material also contributes to cost efficiency.
- **Plywood and Aluminum**: Plywood enhances warmth in the interior while adding structural support, with aluminum used for durability and low maintenance in window framing.
- **Glass**: Large windows maximize natural light, fostering a connection between interior and exterior environments.

These material choices illustrate a commitment to resourcefulness, as well as the integration of environmental consciousness into the architectural design. Additionally, the use of prefabrication techniques enhances construction efficiency, minimizing waste and ensuring quality control during assembly. The design strategically incorporates energy-efficient elements, such as optimized window placement to maximize natural light and breezes, aligning with passive solar heating principles.

`
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.
