Floating Microhomes Constructed with Structural Reinforced Concrete and Expanded Polystyrene for Sustainable Coastal Living

Project in-detail

Constructed using buoyant Structural Reinforced Concrete panels and Expanded Polystyrene, the floating microhomes in Achziv offer a sustainable living solution that integrates seamlessly with the coastal environment while promoting community engagement.
5 key facts about this project
01
Floating microhomes designed with interlocking SRC panels for quick assembly.
02
Incorporation of EPS for enhanced insulation and buoyancy in coastal conditions.
03
Integration of a hydro-electric power station utilizing the nearby Kziv stream.
04
Community amenities include a promenade and scuba diving facilities alongside residential units.
05
Sustainable water systems employing atmospheric water extraction technology.

**Location and Concept Overview**

Located along the Achziv coastline in northern Israel, near the Lebanese border, this project focuses on the creation of a micro-community comprising sixteen floating microhomes. The design intent is to promote sustainable living that addresses contemporary environmental concerns while integrating seamlessly with the coastal ecosystem.

**Materiality and Construction**

The microhomes employ a Structural Reinforced Concrete (SRC) panel system, which is prefabricated for rapid assembly in remote coastal areas. Key materials include SRC panels, expanded polystyrene (EPS) for insulation and buoyancy, and wave fabric to enhance water resistance. Each unit features interlocking panels designed to facilitate efficient transport and installation without the need for specialized tools. Internally, the homes encompass 25 square meters, including essential living spaces such as a kitchenette, sleeping area, and bathroom. Sustainable water systems, like the Biorock for recycling and the Watergen for atmospheric water extraction, are integral to the design.

**Community and Ecological Integration**

The project promotes a holistic vision of community living through shared amenities, including a promenade for social interaction and a hydro-electric power station sourced from the Kziv stream. Additional facilities for scuba diving and an observatory foster connections with the natural environment. Commitment to ecological preservation is evident in the efforts to safeguard local wildlife and increase biodiversity through native plant landscaping. The project also incorporates cultural heritage elements, establishing a research center that functions as a bazaar to revitalize local traditions. Collectively, these features contribute to a sustainable and socially engaging living environment.

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.
