Carbon Fiber Arches and Timber Trusses Create Compact Urban Living Space

Project in-detail

Supported by carbon fiber arches and timber trusses, a compact living unit integrates sustainable features in an urban void of Soho, providing a functional space for modern city living.
5 key facts about this project
01
Support Structure uses carbon fiber arches for lightweight strength.
02
Timber trusses provide lateral stability to neighboring buildings.
03
Rainwater and greywater systems enhance environmental sustainability.
04
Flexible interior layout maximizes functionality within a compact footprint.
05
Access is integrated through a corridor in the neighboring building.

Void House is an innovative solution for utilizing urban voids in Central London's densely populated areas. Located in Soho, the project repurposes a partially demolished townhouse to create a compact living unit. The design focuses on making the most of overlooked spaces, offering a minimal and self-sufficient home that fits within the architectural landscape of the city.

Structural Framework

The core of the design consists of carbon fiber reinforced polymer arches that provide structural support and stability. These arches are anchored to the side walls of neighboring buildings, allowing for a lightweight construction that has little impact on the existing urban environment. This method highlights how architecture can adapt to limited spaces while maintaining the safety and integrity of surrounding structures.

Support and Stability

Timber trusses have been added to provide lateral support, ensuring stability for the adjacent townhouses. This thoughtful integration combines new and existing architecture, creating a balance between the old and the new. The design brings out the potential for innovative spaces within a historical context, demonstrating that new constructions can enhance rather than disrupt an area.

Spatial Organization

The layout of Void House is designed with practicality in mind. Distinct areas include a bedroom, a working kitchen, and a flexible platform that can fold away when not in use. This intentional arrangement allows for efficiency and adaptability, making the most of the limited space available. Each area serves a purpose, meeting the needs of urban living without feeling cramped.

Sustainability Features

Incorporating sustainability into its design, the unit features systems for rainwater harvesting and greywater treatment. These elements support responsible resource use and promote eco-friendly living. The integration of such features addresses growing concerns about environmental impact, making the project relevant in today’s urban context.

An important detail is the use of prefabricated elements, which streamline the construction process. This approach not only makes assembly more efficient but also allows the living space to be reconfigured easily. The focus on modularity ensures that the design can adapt over time, catering to the evolving needs of residents.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
