Everything revolves around creating a new normal.
A normal where we build high-performance structures using natural materials, blending heritage techniques with new technologies. The best of both worlds.
Also empowering self-builders with information, transparent communication and a design process led by your dreams and vision.

Working with you and your existing team to make the most of an overlooked palette of materials and techniques.

Natural insulations not only keep the building warm in winter but cool in the summer. They help balance the temperature; storing heat and releasing it later, creating a consistent and gentle temperature gradient.
Natural materials do not contain VOCs and other chemicals which off-gas during their lifetime. We spend a lot of time in our homes and buildings and it makes clear sense to us not to pollute the air our families breathe. Clay plasters actively filter the air, preventing mould spores which are also bad for your health.
Natural finishes are vapour permeable, allowing a building to move moisture from interior to exterior so the building will not suffer from damp, mold, and rot. People are a huge source of moisture; showers, boiling kettles and breathing all release millions of tiny droplets of water. Natural plasters like clay and lime actively take moisture out of the building.
Natural materials and heritage techniques make the most of gentle curves and soft shapes, as well as the natural grains of wood. They are however, versatile and lend themselves well to contemporary architecture, integrating seamlessly with bold new designs and traditional or alternative buildings should that be required.
Natural materials are excellent acoustic insulators, helping to create quiet, calm spaces that can be easily isolated from each other. Whether it’s a bedroom within your house or an adjoining property.
