Now based in Denver, Colorado, Caswell Design Group has worked on projects in Sydney and New York. Our focus is predominantly design and build in hospitality, commercial and high-end residential.  However we also specialize in owner's representation, branding and graphic design.  




Finding the balance between form and function to create captivating and evocative, yet workable and lasting spaces.  Exploring new ways to develop a sense of style and sexiness, warmth and comfort within a space.  To take people away from their everyday world and transport them to a place where they can feel confident and relaxed.  Designing practical and appropriate spaces that visually, physically and mentally stimulate.  Using raw, natural, salvaged and new materials in clean, eclectic, sustainable ways to bring a space to life.  To create an unforgettable experience.
