Hi, I’m Joanna Sque—founder of Harmony Design Ltd, award-winning interior designer, BIID-registered professional, and specialist in creating beautiful, inclusive spaces that work for real life and real business.

Whether you’re a homeowner planning your dream home or a business owner needing a space that impresses and performs, I design interiors that balance luxury with function and personality with purpose.

I trained at the National Design Academy (NDA) and bring nearly 20 years of hands-on interior design experience to every project. I launched Harmony Design to offer a complete, stress-free interior and architectural design service. Over the years, I’ve built a highly trusted team of tradespeople, architects, builders, engineers, and suppliers who help bring our designs to life across the South of England—from elegant family homes to accessible spaces, boutique hotels, retail spaces, and offices.

I help busy people who are confused about how to create their dream interior. I offer full-service interior architecture designs for both residential and commercial projects. Every project starts with carefully planned layouts and photo-realistic CGI visuals, so you can see exactly how your space will look and feel before any building begins.

From there, I can manage the full design journey:

• Permitted Development & building control applications

• Structural layout and space planning

• Technical drawings for electrics, lighting, kitchens & carpentry

• Trade recommendations or project coordination

• Interior design, styling, and furniture sourcing

• On-site support and regular updates throughout

Whether you’re opening a boutique hotel, reconfiguring a busy office, or extending your family home, I help you make confident decisions without the overwhelm.

My approach is calm and practical. I believe the heart of a well-designed space is in good spatial planning. Once the space is laid out well, we can add interesting textures, calming neutral palettes, and pops of colour to bring the space to life. The results are interiors that feel as good as they look.

As a mum of two living in Dorset, I know how important it is for homes to support family life; as a business owner, I also understand how businesses need to be effortlessly functional and reflect your brand. That’s why I blend creativity with clarity, ensuring every space flows with intention, beauty, and purpose.

I’m a proud, registered member of the British Institute of Interior Design (BIID)—the UK’s leading professional body for interior designers. Membership requires formal qualifications, a minimum of six years’ experience, and a commitment to professional standards and ethical practice.

I’m a multi-award-winning interior designer, recognised for my commitment to creating beautiful, inclusive spaces that blend luxury with functionality. Some of my recent awards include:

🏆 Best Disability-Friendly Interior Design Studio – 2025
🏆 Residential Interior Design Agency of the Year – 2024 (Corporate LiveWire)
🏆 Winners of Multiple South England Prestige Awards

I take great pride in being acknowledged for my work in accessible design. I firmly believe that, with careful consideration and attention, we can craft modern, non-clinical spaces that are accessible to everyone. Whether designing a welcoming space for neurodivergent staff, creating accessible luxury homes, or future-proofing busy family properties, I believe thoughtful interiors should support everyone who uses them.

“Jo has been absolutely fantastic in helping me design my new kitchen/diner extension. She has so many creative ideas I would have never thought of and has helped take all the stress away from making all the decisions. From tile colours, paint, kitchen layout and lighting and every other detail, Jo has been there to help me through it on such important decisions. I’m so excited to now see the end result and will always be so grateful I found your Facebook page.”
