Who we are

Our Team

We employ and develop talented people with the passion, energy and commitment to deliver class-leading results. We believe that our clients deserve to deal with a single Account Manager from initial discussions through to delivery, installation and defect rectification. In this way we protect project-specific knowledge and ensure that consistent standards are applied.

    David Mackie, Principal

    I established Interion in 2012, to create a truly independent furniture consultancy exemplifying best practice in the specification, supply and installation of business furniture.

    My primary responsibility is to find, develop and look after the best operational team in the business, ensuring that they maintain Interion’s core values while being happy and healthy in their working life. I’m also a disseminator of knowledge and experience, based on a long and varied career in working environments.

    Having obtained a degree in Social Psychology and Methods of Social Research, I applied these skills with Space Planning Services as a consultant. Here, I developed interior design skills, joining Steelcase Inc. two years later, initially as a designer for major projects.

    At Steelcase, I undertook many roles including National Accounts, Product Development and Marketing, but after 5 years of corporate life I wanted to see if I could run my own business. I teamed up with an ex-colleague to establish the first UK dealership for Haworth Inc., delivering multiple major projects for leading global entities.

    Despite this success, I became increasingly concerned with many aspects of the ‘tied dealer’ business model, and in 1992 elected to make the business totally independent, so that it could properly source and supply the products best suited to individual customer’s needs. I developed the business to include full design and construction services, and the company grew to be one of the most trusted in the industry with an annual turnover of circa £30m.

    By 2012, after following a Christian path, I had begun to re-assess many aspects of life, realising that financial success alone was not an adequate reason to work. My dream was to establish a business that represented the highest ethical standards, taking every opportunity to give more to its customers, suppliers, employees and good causes. With my deep understanding of the furniture world as a consultant, corporate employee and independent, it was natural that Interion would be a business furniture specialist.

    Steve Pearce, General Manager

    I’m responsible for all the core operations of Interion, reporting to Principal David. All other team members report to me; I delegate, motivate, guide and support them in accordance with Interion’s values. I also manage a number of customer accounts directly.

    I joined in 2017 as an Account Manager, and have progressed to my current position through rigorous attention to detail and an ability to develop and sustain positive working relationships with customers, colleagues and suppliers.

    With a BSc in product design, I worked first on placement and then full time for a specialist bespoke furniture design & manufacturing business. I was able to apply a wide range of design skills and learn ‘on the ground’ about the process of effective furniture design and delivery.

    I wanted to develop these skills applied to whole projects rather than just the bespoke elements, which is why I joined Interion. Here, working with David and the wider team, I continue to learn – not only about the practicalities of effective delivery, but about the importance of applying consistent values and acting with integrity.

    I love our dedicated team; we are all hardworking, diligent individuals who support each other in a spirit of trust, co-operation – and fun! Our combined knowledge and expertise is second to none and it’s a great pleasure to apply this knowledge in a way that benefits our stakeholders and wider society.

  • Fiona Tmava, Senior Account Manager

    Fiona Tmava, Senior Account Manager

    As a Senior Account Manager, my role is to advise and support clients throughout a project’s lifecycle – from the initial meeting, through solutions development, to delivery and installation. I look after a wide range of customers and have undertaken a series of major projects throughout the UK and Europe.

    I joined Interion in April 2019 as Team Administrator. Thanks to the recognition of my hard work and exceptional training from David and Steve, I was promoted to Account Manager in September 2019, and more recently, to Senior Account Manager.

    Having obtained a Distinction in the Architecture Foundation Course at University of the Arts, I obtained a BA (Hons) Architecture RIBA Part 1 at University of Westminster. I worked for a private architectural practice, then as an Architectural Assistant for a construction company, before accepting that I preferred furniture to architecture! However, this foundation has given me a great technical knowledge and an appreciation of the processes involved from design to delivery.

    Interion has been an amazing experience for me; their values-driven approach is very much a reflection of my own, and I’m given the independence and authority to act in the best interests of my clients, with support from the Interion team when required.

  • Jack Nicholls, Senior Account Manager

    Jack Nicholls, Senior Account Manager

    I joined the Interion team in October 2019, since then I have been working closely with the team to provide support with existing accounts and more recently bringing in new opportunities and projects for the company.

    Previously, I worked with a design and build practice supporting the build team with all their furniture requirements from small to larger projects around the country. Prior to this I was with a furniture dealership outside London for 2 years. Through these experiences I have a been able to develop my knowledge of the industry, and I can offer clients coherent and expert advice and support for all their furniture and project requirements.

    I have a BA (hons) degree in sport & exercise management from the University of Kent. I was a personal trainer and coach for two years before joining the industry, and I have a huge passion for all sports and outdoor activities. I am currently working on several music projects with my band and look forward to finally being able to play live music again this summer!

    Interion has given me the platform to express my abilities and use my experience to run large projects from start to finish. I chose to join Interion because I believed in David and Steve’s vision, their values and it was a chance for me to learn from and develop with them both. The team around me are terrific, they support me in so many ways and we really are the trusted furniture experts!

  • Graciela Soto, Team Administrator

    Graciela Soto, Team Administrator

    I’m Interion’s Team Administrator, which means that I do anything and everything to support my colleagues and keep our systems and processes running smoothly, as well as lending a hand with social media.

    I was born and raised in Venezuela, finalising a degree in Journalism and Mass Media, then moved to Boston to study digital cinema. After moving to London, I started working in high end retail of luxury furniture, which in turn led to a position with an online commercial furniture distributor.

    I love working here because I get to embrace my best skills and learn from the team, who share their knowledge and experience generously. Despite lockdown, I have grown as both a professional and a human – I’m totally in-tune with Interion’s values and ethics. I’m lucky to work with such trustworthy, resilient, fun, kind and hardworking talented colleagues who always have the best attitude, regardless of the situation.

    I enjoy spending time behind Excel sheets and making sure all the admin is up to date. With an outgoing and enthusiastic personality, I’m also pretty good on the ‘phone – I particularly enjoy finding answers for our customers and keeping up to date with the latest innovations from our suppliers, so I can share this information with the team.

  • Lisa Carlton, Furniture Consultant

    Lisa Carlton, Furniture Consultant

    As a consultant for Interion, I bring in new and established clients to experience what Interion has to offer in service, experience and product variety.

    Starting in this industry back in 1998, I have seen many changes along the way, having worked for small and large dealers and for one of the largest furniture manufacturers in the UK. My training has all been ’on the job’!

    I work closely with clients to establish their needs, creating solutions and ‘making the practical look good’ within budget. Interion have a vast array of manufacturers of all different specialties in order for me to achieve this for my clients, which include large national blue-chip Corporates, Councils and smaller businesses. All are treated with the same respect, courtesy and the best service possible.

    I think one of the best developments of recent years is to be able to produce high quality renders quickly and easily to give clients a good visual of what their space could look like in 3D.

    My Christian beliefs mean that I have a strong work ethic and that I will not compromise on truth and honesty. Money is not my motivation, but it is healthy for people to work and to help others to have good and healthy work environments.

    I can honestly say that I love meeting new people through my work, and the relationships I have with my client’s I have had for many years and with my colleagues make working good fun – there is no reason why it shouldn’t be fun! I used to keep work and home life separate, but as time goes on, I believe there can be a blurring of the edges to this without detriment to either - in fact it can be beneficial.

  • Kevin Topham, Development Consultant

    Kevin Topham, Development Consultant

    As Development Consultant, my job is to bring Interion’s extraordinary ability and reputation to the attention of a wider audience. I have been enthused by their thoughtfulness and contribution to the debate about the future of the work, bringing my own skills, including the ability to undertake workplace health & safety assessments.

    My background is in commercial furniture engineering and manufacturing, working with UK and International blue-chip clients, and partnering with international suppliers, including the far east.

    Having worked ‘client-side’ in project procurement and management - developing further skills in surveying and workplace design feasibility - I have a wide-ranging perspective on client needs.

    With further experience in moves management, I have spent the last 15 years as Project Leader for a London design and build organisation. I also served as project lead and main liaison as part of London Legacy Development Corporations' stadium transformation project, successfully providing the complex feasibility, design, successful implementation & delivery of the stakeholder headquarters.

    I’m committed to supporting clients with world class insight, experience, and customer service – and what I love about Interion is that they share these commitments, along with the values and knowledge to deliver.

Insight, Uxbridge






Technology Solutions

Working in collaboration with Maze Workplace, this bespoke-led project involved many different products, which all required high amounts of detail to achieve a superb result.

Biophilia was intended as a central theme from the beginning, so we ensured that many sections of ‘grid’ space-dividers featured plants - and the space on top of lockers was also designed to have planters throughout.

Our artisan banquettes were crafted by Atlas Contract Furniture. Meeting tables and grid by ORN. Lockers, planters, and storage by James Tobias.

Lloyds Avenue, London






Serviced Office

Working in partnership with TFT and Structure Tone, we have delivered 2 floors of furniture at 8 Lloyds Avenue.

Set in an iconic part of London, this space was designed as a tenant-ready quality serviced office; It was important that the specification would sell the space and remain flexible enough to attract many different types of companies.

The space features Muuto lounge and meeting furniture, Spacestor Palisades, Vitra Belleville, Hay Pyramid, Humanscale World Task Chair, Task Systems meeting tables and Workstories desking.

Ninja Theory, Cambridge






Video Gaming

One of our most exciting clients we have had the pleasure to work with is the gaming company Ninja Theory. Set in a beautifully designed space by Tala Fustok, our brief set by TP Bennett & Francis Hunter, was to design, develop and produce a completely bespoke desk solution for Ninja’s unique requirements. All of which was delivered during the peak of the pandemic.

The process involved a competitive process and various mockups of the desk which allowed us to fine tune every aspect of the design. Our final product was a nano laminate construction throughout, with a unique bolt system for setting the desk height, and lockable extra-wide cable trays to manage their extensive IT cabling requirements.

As well as the desks we provided accessories including Humanscale M/Flex Monitor Arms, Humanscale Nova Task Lights, Tecta Stationery holders, and Ion Duo Aircharge units.

The solution was developed in partnership with our recommended partners Alchemy Furniture, who were outstanding with their level of detail and service throughout.

Derivco, Ipswich






Online Gaming

We were delighted to be approached by a long-standing client who had moved to Derivco. This project would end up spanning across multiple floors, locations and even countries.

Our initial brief was set by Derivco and Verduyn Architecture to provide new furniture for their Ipswich office. We formed a great relationship with the project team, which led to expanding our brief to include bespoke furniture, home working products and a new office in Barcelona.

We worked alongside partners Structure Tone, who delivered the fit out, and Waste To Wonder, who removed existing furniture for donation to charity.

Supply Partners

Atlas Contract Furniture, James Tobias, OCEE, Workstories, Hitch Mylius, Elite, The Meeting Pod Co., Frovi, Connection, Muuto, Wilkhahn and UBI

Sartorius Stedim, Havant







Sartorius wanted to accelerate the production of downstream processing equipment. These systems are vital for the manufacture of injectable drugs as treatments for cancer, diabetes, and viral vaccine production. We put together a furniture package which would help to accelerate production processes, while improving staff wellbeing, engagement and productivity.

The space includes electronic sit-stand workstations, functional and contemporary meeting spaces, breakout spaces, personal/private workspaces, and vital production spaces.

Throughout the design phase, we identified the best products on the market for the client’s budget, whilst meeting the requirements for functionality, aesthetics, and quality. As a trusted independent furniture dealer, we were able to source furniture which not only met the required standards, but reduced the anticipated budget. We managed the installation from start to finish to ensure the client was happy with every element. Working closely alongside the IT and AV teams to ensure precision and clarity between services.

Supply Partners

Assmann, Interstuhl, Connection, Hitch Mylius, Tables For Business, Senator, CBS, Bisley & Bott.
