Douglas House

Douglas House is a custom-built residential project located in Winthrop, Washington. The project is focused on the use of innovative building materials and sustainable design practices to create a unique, environmentally friendly living space.

The house is constructed primarily of Cross-Laminated Timber (CLT) walls and roof panels, which provide a high level of structural strength and insulation while minimizing the overall carbon footprint of the building. In addition, the floors are made of Glue-Laminated Timber (GLT) planks, which offer a durable and sustainable alternative to traditional concrete or steel flooring systems.

To support the structure, the house also features Glulam beams, which provide both strength and aesthetic appeal. These beams are constructed by laminating multiple layers of wood together, resulting in a strong, resilient support system that is also visually striking.

Douglas House is a cutting-edge example of sustainable design and innovative building practices. With its unique use of CLT, GLT, and Glulam materials, it stands as a model for environmentally conscious residential construction in the 21st century.

    North American forests grew this much wood in 14 seconds.

    This project kept 110 metric tons of carbon from entering the atmosphere.

    This is the equivalent of keeping 23 cars off the road or providing clean power to 21 houses for a year.
