## Overview

**Project Title:** Laut: Homes by the Ocean
**Site Location:** Lazarus Island, Singapore
**Design Purpose:** Laut is conceived as a microhome providing temporary accommodation for professionals working on Lazarus Island. The design emphasizes sustainability, intending to create an off-grid living space that harmonizes with the coastal environment.

Lazarus Island, located off the southern coast of Singapore, is predominantly uninhabited, offering a contrast to the densely populated urban landscape of the region. By fostering a connection to the natural surroundings, Laut aims to embody the essence of relaxation associated with coastal living, drawing inspiration from the Malay word "Laut," meaning "ocean."

## Design Elements and Materiality

The architectural framework incorporates modern materials selected for their environmental performance and structural resilience. Cross-laminated timber (CLT) serves as the primary structural component, emphasizing rapid assembly and durability. Polished concrete is employed for patios, chosen for its weather resistance, while concrete tiles on the roof provide longevity and protection against heavy rainfall.

Sustainable water management practices include rainwater harvesting systems and atmospheric water generation technology, enabling the production of potable water on-site. Solar integration is achieved through photovoltaic panels, designed to generate surplus energy, supporting the home's off-grid status.

## Spatial Configuration

The design optimizes natural light and air circulation through extensive openings oriented along the North-South axis, ensuring that approximately 89% of interior space is daylit. Essential living areas, including a kitchen and bathroom, are thoughtfully arranged to maximize functionality while minimizing spatial waste.

Interior finishes combine aesthetic simplicity with durability, utilizing smooth timber panels that complement polished concrete features. The porous facade enhances ventilation, addressing humidity and temperature concerns while facilitating natural airflow within the home.

Emphasizing modularity, the design allows for customization to meet user preferences, fostering an adaptive living solution conducive to temporary or seasonal occupancy. Additionally, the project incorporates local cultural elements, ensuring an authentic connection to the indigenous environment and landscape.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
