K&K Interior Design Studio, based in Beckenham, Kent — where thoughtful design meets well-being.

We are Karen & Konrad, a husband-and-wife team combining interior design and bespoke carpentry to create beautiful, functional spaces that truly feel like home. With backgrounds in interior design, psychotherapy, and skilled craftsmanship, we understand how deeply your environment affects the way you live, work, and feel.

Our approach is simple: your home should support you, reflect you, and enhance your everyday life.

Welcome

Our mission is simple: to help you create a space that reflects who you are while improving the way you live. Whether it's re-imagining layouts for better flow, incorporating bespoke carpentry for smarter storage, or curating colours and textures that bring a sense of calm, we design with well-being, function, and personality in mind.

We know that design can feel overwhelming, but we're here to make it an exciting, collaborative journey — one that's approachable, creative, and tailored to your needs.
