Employing a unique, inclusive methodology allows us to create exciting environments that are #MakingWorkLive for our clients.

By analysing data, we can incorporate workplace strategy into our approach. Whether it's through Interviewing staff, performing storage audits, or simply talking to people anecdotally, we obtain a deep understanding of how people and departments within an organisation interact and work together. Observation is key in ensuring the design of an office enhances the working environment and the experience of those within it.

Taking inspiration from leaders in education and technology, 3equals1 creates durable spaces that primarily work for their clients' needs but also sit ahead of the curve. Our human-centred, organic approach to workplace design guarantees that clients get properly involved in the process. We are inspired by the way people utilise their spaces and strive to create the best environments possible by researching in depth the psychological and physical aspects.




Maz Mahmoudi - CEO & Designer

Hi I’m Maz!

Some may say that I am a destroyer, but really I’m a fun lovin criminal! I work hard and play harder.

Being an Iranian South Londoner doesn’t mean I tan very well but my big hair keeps me warm on the cold winter days.

I started 3equals1 Design in 2010 and am loving doing the weird and wonderful creative things that get thrown at us.

Tash Cruder - Director & Designer

Hi, I’m Tash,

Born and raised in London with 12 years’ experience in Interior Architecture. I take my work seriously but not myself - life’s for living!

I am privileged to have travelled the world and on that journey seen and experienced many beautiful wonders and adventures. Seeing the Siloli desert (also known as the Dali valley where Salvador Dali took his inspiration) was unequivocally one of my favourites.

Regarding work, it's imperative for me that the design journey is fun and dynamic. I design with a strong sense of place and purpose. Approaching every project individually and exploring the unique objectives of each client is what makes each design I create bespoke and interesting.


Harry Clayton - Designer

Hi I’m Harry!

I studied Interior Design at university and graduated in 2016. I love design for the real impact you can have on people’s lives. It gives great satisfaction to feel like you have helped make a difference for the better.

I was born in London and have always lived here and spend my spare time at Chelsea watching the football surrounded by family and friends.

Gert van Dam - Designer

Hi, I’m Gert!

As you can probably see from my name I’m born and raised in the country of tulips and windmills, not too far from Amsterdam.

Since November 2017 I live in crazy London and so far the parks, pubs, museums, the great London atmosphere and obviously my work make me feel home in this part of the world! In 2015, I graduated as an interior designer at ArtEZ institute of architecture, in the Netherlands.

I like to translate ‘stories and identities’ into space and design. Especially for larger organisations where design goes beyond personal taste and where more focus is placed on shared convictions and ideals. That’s why working for 3E1 is such a great experience - we are a varied team of people making work live for our clients.

Natalie Brady - Relationship Manager

Hi, I’m Natalie!

I have a real passion for design and originally trained as a furniture designer and maker. I spent several years building a portfolio of work and as well as being featured at the London Design Festival, my work on one occasion took over the entire Heals window display. Thankfully, I managed to retain all of my fingers!

I now look after business development for 3Equals1, which allows me to utilise my favourite skill: meeting new people and building relationships. I definitely prefer cold beers to cold calls!

Let's chat!

Being able to choose from a diverse range of styles within the team is a huge advantage to potential clients.

We are a team of creative individuals who each have their own style but importantly we work well together. Fostering an environment in which the individual styles and personalities of our team are allowed to prosper benefits the overall output of the team and helps us maximise the synergies that we possess.

Indeed, by allowing our own individual styles to flourish in a co-operative team environment, we can cater for a broad spectrum of clients with varying tastes. Evaluating who is best suited for each client means the success of the project is given a higher priority than the ego.    




Constantly learning about our industry and being aware of new trends and developments are essential ingredients in what we provide 


Our hunger for knowledge manifests itself in regular visits to trade shows and manufacturers. We work with the best people in the business and always pass on this learning to our clients. We happily admit to not knowing everything and rely on the knowledge and expertise of our manufacturers just as much as our own skills.

Each project has its own unique solution – working with the right suppliers helps us to succeed. In our opinion, the attitude that one size fits all no longer exists in this industry. 3e1's services featured below are powered by a comprehensive tool set which enables us to create environments that are both functional and aesthetically pleasing.
