Timber Retreat with Green Facade and Exterior Bathtub

Project in-detail

An exterior bathtub occupies the space beside a green facade, harmonizing with rainwater collection and solar energy systems in a compact cabin designed for versatile retreat functionality.
5 key facts about this project
01
Green facade supports local biodiversity.
02
Roof collects rainwater for efficient water management.
03
Solar panels provide energy self-sufficiency.
04
Exterior bathtub enhances outdoor living experiences.
05
Timber construction merges traditional techniques with modern functionality.

The cabin project explores the blend of modern design with traditional building techniques, situated in a landscape that enhances its overall character. It serves as a contemporary retreat while incorporating sustainable practices in its design. The concept emphasizes a user-friendly environment, allowing both functionality and adaptability to meet the needs of those who inhabit it.

Architectural Form

The cabin has a south-facing facade that is covered in plants, creating a connection between the building and its natural surroundings. This green facade not only adds to the visual appeal but also supports local wildlife. The design reflects a balance between modern architecture and traditional elements, ensuring that the structure fits well within its environment.

Functional Layout

The interior is organized to make the most of the available space, which measures 56.66 square meters. Key areas include a lounge, kitchen, and shower, along with a terrace that encourages outdoor living. Each space is thoughtfully designed to serve a specific purpose, creating a smooth flow that enhances the living experience. The layout effectively uses every square meter, focusing on comfort and ease of movement.

Sustainability Features

A key aspect of the design is its commitment to sustainability. The roof collects rainwater that drains into a cistern, promoting efficient water management. Solar panels are also integrated into the design, allowing the cabin to generate its own energy. This focus on self-sufficiency speaks to current trends in reducing environmental impact in architectural design.

Materiality

Timber is the primary material used in the construction, representing traditional building methods while also supporting sustainability. Industrial I-beams are used for additional structural strength. This combination of materials ensures durability while creating a warm atmosphere that complements the landscape.

The design includes an exterior bathtub and shower, allowing residents to enjoy a close connection to nature. This feature adds to the overall charm and functionality of the cabin, reinforcing the blend of indoor and outdoor living.
