### Overview

Located in a densely populated urban context, the TreeHive project proposes a unique residential model while prioritizing sustainability and community engagement. The design integrates communal spaces alongside individual living units, aiming to enhance the quality of life for residents and address the challenges posed by a demand for affordable housing.

### Spatial Modularity and Growth

Central to the design is the principle of "grow-as-you-need," which accommodates changing demographics and evolving community needs. The structure features a tree-like form that supports vertical expansion through a modular system, allowing the addition of living spaces and communal areas over time. This approach not only addresses immediate housing needs but also ensures adaptability in response to shifting population dynamics. Triangular platforms provide stability while facilitating interaction among residents, allowing for the seamless integration of shared amenities, such as parks and community centers, into the overall living environment.

### Sustainable Materiality

The project's material selection focuses on resilience and environmental sustainability. Key materials include cross-laminated timber (CLT) for structural warmth and sustainability, steel trusses for load distribution, and concrete for foundational stability. Large expanses of glass enhance natural light and create visual connections with the outdoor environment. Additionally, green roof systems support biodiversity, contributing to the building's ecological footprint. These materials are carefully chosen to reinforce the project's commitment to fostering a connection between residents and their natural surroundings while promoting overall well-being within the urban landscape.

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.
