5 key facts about this project
01
Integration of bat shelters at both ends of the building promotes local biodiversity.
02
Use of locally sourced black charred wood siding enhances regional connection.
03
Footprint precisely mirrors the original longhouse to preserve historical context.
04
Design includes solar panels for energy efficiency and reduced environmental impact.
05
Open layout fosters community interaction and adaptability for various activities.

The Bat House project features a design that responds to its historical context and natural surroundings. Located in an area where aging structures tell a story, the building aims to serve communal needs while honoring the existing architecture. The design draws from the longhouse's layout, preserving its shape while incorporating modern functions that cater to contemporary lifestyles.

Architectural Intent

The building’s low and elongated form is a central feature, allowing it to blend into the landscape. The design respects the geometry of the historical longhouse, creating visual and physical connections with the site. Arranging the new structure in relation to the environment promotes easy access to outdoor spaces such as gardens and pathways, inviting people to engage with their surroundings.

Material Choices

Selected materials play an important role in the design. Exposed concrete with a vertical pattern forms the building's primary structure, providing strength and a natural appearance. Lime plaster on the walls adds a friendly texture that feels warm and inviting. The choice of locally sourced black charred wood siding helps connect the building to its locality, while dark zinc roofing sheets offer a sleek finish that is built to last.

Interior Functionality

Inside, spaces are designed for comfort and practicality. The layout includes various areas, such as a workshop and living spaces, encouraging interaction among users. These spaces are adaptable, allowing them to cater to different activities throughout the day. The focus is on creating an environment that supports community use while remaining functional for individual needs.

Integration of Sustainability

Sustainability features prominently in the design. Solar panels are integrated into the overall structure, underscoring the commitment to energy efficiency. This choice reflects a desire to minimize the ecological impact of the building while ensuring it meets modern energy standards. Furthermore, the design includes sheltered areas for bats, positioned at both ends of the structure. This detail not only enhances local biodiversity but also fosters a connection between the built environment and wildlife.

The structure demonstrates a thoughtful approach, where design and nature coexist and support each other, creating a richer experience for the community and the environment.
