Inspiring Interiors



Kewley & Trebble specialise in providing flexible and tailored interior designs to any brief.

Between us, we have over 25 years of experience creating stylish and comfortable residential interiors and award-winning boutique hotels – and now we’re applying our impeccable taste to Sussex’s country interiors. Our approach is friendly, down to earth and practical – and our aim is to translate your brief and realise your vision with inspired, elegant and timeless solutions. Your project will always be personally handled by us.

We also have expertise in designing bespoke furniture and joinery. Our attention to detail, and our relationships with local craftsmen, artists and manufacturers ensure high quality work. Our repeat business and frequent referrals are testament to the quality of our work.



Whatever your vision, we can deliver flexible and tailored interior designs – from a simple concept to a full design scheme with drawings. To ensure we understand your needs, our service begins with a complementary consultation in your home or office. After careful consideration of your brief, we will provide you with a fee structure for your project. Each one can be provided as a standalone service, or integrated into a larger project that can be managed by us if you wish. This may be an hourly rate for a small project, or a fixed price to design and make fitted wardrobes or plan your new kitchen.

  • Emma and Matthew did an amazing job of interpreting the vision we had for our new home. They created an internal layout for the refurbishment and extension of our home that had the flow, space and functionality we needed. They thought of things we never knew we needed and created an amazing floor plan that wowed even our architect! Their design know-how has been invaluable at this early stage of our house project and I am now looking forward to working with Emma and Matthew at the next stage.

  • Emma and Matthew are a joy to work with. They listened well and understood what we wanted to achieve, and they brought loads of great design ideas to the table. We were impressed by their eye for detail, and their commitment to the project. They were involved from start to finish, and the end result is a beautiful family space which is both inspiring to look at and easy to live in. We are really pleased with their work and would not hesitate to recommend them to future clients.

  • Matthew and Emma guided us through the creative process. We came to them with lots of our own ideas, especially for the bedrooms. They really helped us enrich our perspective and expanded our own sense of design. We were immediately inspired by their excitement about what is possible. For the kitchen and living area we weren’t so sure what we wanted. Their design knowledge is exceptional, and they made suggestions that fit our aesthetic as well as giving us a way to make decisions based on a vision of our home as a whole. Our home exemplifies comfort, but every detail is alive and impossible to take for granted. The end result is so satisfying. We highly recommend them.

  • Emma and Matthew were a pleasure to work with through out our family kitchen extension project.  The kitchen design they produce was so innovative and inspiring, and everything is in the right place.  It works.  They understand what a family home needs.  They are professional and pay attention to every detail.  I would not hesitate recommending them as talented and conscientious designers.
