About this home

A Small Footprint, Big Impact: A Mid-Century Modern Retreat by Northern Edge Studio

Northern Edge Studio proudly presents a home that redefines compact living. Blending mid-century modern aesthetics with cutting-edge sustainability, this 7-star energy-efficient home is a celebration of thoughtful design, natural materials, and innovative green technologies.

Inspired by the iconic designs of William Krisel, this home features a striking butterfly roof that not only captures breathtaking views but also fills the interiors with natural light. The dramatic roofline pays homage to mid-century architecture while providing a modern twist, seamlessly integrating form and function.

Despite its efficient footprint of just over 100 square meters, this home offers everything a family needs: three bedrooms, two bathrooms, and two living areas. The design optimizes every square meter, creating a sense of spaciousness and comfort while maintaining a compact, sustainable footprint.

Every material was chosen to enhance both sustainability and aesthetic appeal and sustainable construction.

This home seamlessly blends the charm of mid-century modern design with the demands of a sustainable future. Its compact footprint, innovative green features, and timeless aesthetic make it more than just a place to live—it’s a blueprint for how thoughtful architecture can enhance everyday life while respecting the environment.
