Integrating Green Roof Systems With Hybrid Timber Construction in Sustainable Residential Design

Project in-detail

Utilizing hybrid timber for structural integrity and integrating green roof systems, the design provides an energy-efficient residential solution that harmonizes with its urban environment.
5 key facts about this project
01
Utilizes cross-laminated timber panels for enhanced structural performance and sustainability.
02
Incorporates rainwater harvesting systems for improved water management.
03
Features a bent A-frame design that optimizes natural light and ventilation.
04
Employs charred wooden shingles for durability and fire resistance.
05
Integrates a green roof system to promote biodiversity and energy efficiency.

### House of the Future: Architectural Overview

Located in a modern urban environment, the House of the Future embodies a residential design that prioritizes sustainability and user-centered functionality. The intent behind the project is to create a resilient living space that effectively adapts to contemporary challenges while fostering a connection to nature. The design is organized around the concept of “Volume Finding,” which emphasizes the strategic arrangement of spaces that encourages both interaction and privacy.

### Spatial Organization and User Experience

The spatial strategy incorporates a multi-layered floor plan that delineates zones for private, semi-private, and communal activities. Signature areas include dedicated living spaces, a “Newlyweds’ Apartment,” and outdoor environments designed to accommodate diverse family dynamics. The open concept connecting the living room and kitchen facilitates social interaction and fluid transitions between spaces. Outdoor features such as gardens and terraces promote engagement with the natural landscape while thoughtfully integrating native plants to maintain ecological balance.

### Materiality and Energy Efficiency

The construction materials selected for this project reflect a robust commitment to sustainability. Recycled hybrid timber serves both structural and aesthetic purposes, minimizing the reliance on virgin resources. Concrete slabs offer thermal mass and structural integrity, while glass facades increase natural light penetration and create visual continuity with the exterior environment. The design incorporates advanced energy solutions such as solar panels that generate approximately 2070 kWh daily, and rainwater management systems that provide for 20% of household water needs. Prefabricated hybrid timber-concrete components enhance the efficiency of the construction process, reducing overall environmental impacts while ensuring durability.

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.
