About Us

We Exist to Enable Change

Our clients seek more than architectural ergonomics. They demand sustainable workspaces that foster innovation, wellness, and ecological balance.  And that’s why we’re here: to provide you with interior solutions that encourage creative productivity while minimising your environmental footprint.

About Us

Natural Space Design is a boutique architectural and interior consultancy sized for personal service and attentive project management. We don’t push pre-designed solutions. Each of our clients is unique.

       We start with a radical first step: we listen.

Optimisation is personalisation. Before we start a design, we get to know you. We work with you one-on-one to appreciate your personality, team and goals. Only then can we design your ideal interior and truly meet your needs for functionality, sustainability, and aesthetics.

Meet the Directors

Founder and Creative Director

Hi, I’m Louise Turmaine, an architectural technologist, sustainability enthusiast and the creative director of Natural Space Design.

With an 18-year career in the construction industry and background in technical design, building surveying and operational maintenance, my goal and passion to include sustainable design into our urban environment has led me to opportunities to be involved in a Huf Haus build and the creation of an autonomous house in Wales, UK.

My previous experience working for London Underground and its former subsidiary Tube Lines Limited, has provided me valuable skills in space planning, property management and maintenance, leadership and stakeholder coordination.  I’ve collaborated with numerous design team professionals and contractors to ensure successful delivery of over 100 complex railway infrastructure projects.  My other responsibilities have been managing at multi-disciplined team of twelve, maintaining a portfolio of 3000+ premises, undertaking building surveys, providing the coordination of asset replacement and upkeep along with contractor and supply chain management activities.

But, throughout my career, I’ve observed the impact that poorly designed workspaces can have on employees and productivity. And I’ve watched the construction sector’s growing concern for the natural environment, the time to change is now.

That’s why I founded Natural Space Design: to improve the triple bottom line of people, planet, and profit (the economy). A well-designed building — one with modern lighting, adequate indoor air quality, quiet spaces and flexible design — will always outperform the alternative.

I believe that by using sustainable materials, ergonomic layouts, and functional aesthetics, we can increase both productivity and happiness while protecting people and the impact on the planet. If you think the same, let’s connect.
