Who We Are

Grigoriou Interiors was founded in 2010 by two sisters with an entrepreneurial spirit and a passion for sustainable design. It is one of London’s most forward-thinking design studios, with particular expertise in design for commercial spaces.

We passionately believe that style and sustainability are mutually inclusive: combining an eye for aesthetics with in-depth sustainability know-how, we design interiors that are stylish and look after people as well as the environment.

Unusually for interior designers, we understand the roles and technical work of other consultants involved in project teams – providing clients with the perfect balance of technical knowledge and design expertise.

As a RICS SKA rating Development Partner for the office, retail and higher education schemes, we are at the heart of the latest industry developments and initiatives regarding sustainability. Our involvement in and support of the SKA rating initiative has been instrumental in bringing the system into effect, both in the UK and internationally.

We work with people who share our values and pour our energy into finding creative ways to help them achieve their vision. We then like to celebrate with our clients over a good meal and a nice bottle of wine!



To create interior spaces of beauty and function that look after people and our planet.

Core Values

Believe. Think.
Innovate. Achieve.



Using interior design and thought leadership to provide sustainable physical environments that enable people and businesses to perform and grow to their best, while nurturing our natural environment.

More about Elina…

You could say that my career in interior design started as a teenager, when my decorating attempts involved papering my walls with posters of Mel Gibson, Madonna and Top Gun! Meanwhile, my experience of being signed up by a premiership basketball team in Athens showed me the importance of working together as a team to achieve a common goal.

“My notion of wellbeing in the built environment was initially brought to focus through information around the negative effects from unregulated use of plastic materials in interior flooring. Furthering materials and design research, and combining it with the study of Practical Philosophy and transcendental meditation, I continuously gain wider understanding on what and how interiors can be used positively to allow human flourishing and support a better life.”

Where I find inspiration:Everywhere! The essence of a project is defined by my clients’ needs and their vision. From there, design solutions are informed by things that have inspired me – and that could be a postcard, theatre tickets, poison ivy or graffiti on a wall.

Praise For Our Work

Grigoriou Interiors were brought in during the design phase of our office fit out at Porchester Road to initially provide advice on the environmental accreditation SKA and the benefits of integrating it into the project both for its environmental and sustainability advantages, but also importantly for employee well-being in the space. Their role progressed into full integration in the project team throughout the design and fit out phases, up-skilling us as a client, the contractor and the rest of the consultants, designers and supply chain. Elina, Angeliki and the rest of the GI team’s drive and enthusiasm helped us achieve a Gold Rating, which contributed to the successful delivery of the office space to two Virgin companies.”

My colleagues and I at Construction Youth Trust are delighted with our newly refurbished offices in the Building Centre. The space has had a complete make-over with Elina of Grigoriou Interiors working with the Trust staff to ensure that the redesign meets our needs and increases workability and wellbeing. Elina and her colleagues have worked with us to make the space light, friendly, welcoming and a great space to work. Before the makeover we were reluctant to bring visitors into the space – that is certainly not the case now! We are now very proud of where we work and the morale and output has gone right up. We have all learnt the benefits of good interior design and can share much better with our Budding Brunel students the importance of the relationship between consultants and clients to make a space more than an office. The Mace supply chain worked closely with Elina and her team to ensure that the works were done effectively and efficiently and in the main all pro bono. Thank you from a very happy Construction Youth Trust.”

Christine Townley

Executive Director | Construction Youth Trust

Together, we had set out to set a new direction for the company and the industry, embracing sustainability principles in a tangible, credible and measurable way. Mission accomplished. Not only did our presence look fresh, modern and resonated with the customers. Beyond that, Starwood positioned itself as a leader and innovator, again! You have put enormous effort into this and collaborated with our complex organization very well! I want to say thank you and job well done! We learned a lot from you and look forward to more.”
