“Barr recognised that while aesthetics are important in a home, interior design should ultimately result in a grounding and comfortable space. Drawing inspiration from nature is nothing new for House Nine who prioritise using biophilic design elements — a design style which uses natural elements to create a healthy living space–  for which they’ve garnered a cult following of enthusiasts.” The English Home

Creating beautiful and functional spaces

Our design process is rooted in meticulous attention to detail, where every element is carefully considered. We prioritise detailed spatial planning, optimise natural light, and thoughtfully integrate colours and textures to create spaces that are both beautiful and functional. Collaborating closely with trusted suppliers, architects, and skilled craftspeople, we aim to source only the highest quality materials and employ expert techniques, all while maintaining a commitment to minimising environmental impact where possible.
