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!

  • Darla Dimitrovska, Senior Account Manager

    Darla Dimitrovska, Senior Account Manager

    I was familiar with Interion well before joining the company. I had heard so much about David and the integrity with which he was running the business, that I had no doubt when it was my chance to become part of the team.

    Prior to joining Interion I worked for another dealership where I gained broad experience in specifying and procuring furniture for a variety of projects including workplace, hospitality, and residential, with projects based in the UK and overseas.

    I hold a degree in Interior Design from the Staffordshire University. From a design perspective I believe that the spaces we live and work in need creative solutions to the constant changes in how we utilise them, but more importantly, should support our physical and emotional wellbeing.

    My interest in how the environment affects our wellbeing led me to research biophilic design for my dissertation. I enjoy sharing this approach with my clients, which has proven to increase productivity and employee engagement.

    I’m currently an MBA candidate; I appreciate the diversity of interrelated complexities companies are facing - and I am particularly interested in how interior design can influence organisational culture, values and employer branding.

    Being part of a team of experts is a great opportunity for all of us to influence each other, to share our values and commitment to delivering exceptional results.

  • 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.

What’s the future of the office? Expert views from the Workspace Design Show

The first ‘real’ UK show since 2019 was held at The Business Design Centre on 4th and 5th November – and what an exciting event it was! Packed with enthusiastic attendees, the show floor was buzzing – and a series of ‘Expert Panel’ discussions gave us some real insights into the future of the office.

Our thanks to the organisers, who did an amazing job gathering the best of British and International design talent for the talks programme, and attracting many leading interior product makers to exhibit.

Expert views

The format of the talks was typically ‘panel discussion’ rather than formal presentations. An expert chairperson put questions to the panellists, so we got a nice mix of fact and opinion! Many leading experts of the Design community took part and there was strong sense that we could trust their words as a guide to what the future holds.

We’ve chosen two of these talks as examples; highlighting the main points made by each panellist.

Expert views

Designs to inspire creativity and innovation, chaired by Mark Eltringham

Angela Bardino, Design Principal, Jacobs
Colin Burry, Design Principal, Gensler
Jack Pringle, Managing Director, Studio Pringle

Working from home (WFH) – will it continue?

JP Truthfully, we don’t know, but the most likely scenario is yes, but not exclusively – perhaps 2/3 days a week. WFH is ‘unequal’ – fine perhaps for the executive with a big country house, but less so for younger workers who perhaps live in a rented studio flat and need to be mentored. A ‘place’ of work is far more important to them – they want to meet people and learn, so that they can succeed in their career. They may even meet their life partner at the office!
CB It’s impossible to work as well together creatively if in different places. Personal experience based on two lockdown design projects (one remote, one working in the same space) confirms better outcomes when collaborators are in the same space.
AB Creative (added value’) thinking is about stepping away from the norm; being stimulated by colleagues. WFH can’t replace the collective creative process.

So what will we see in the office?

CB We should use the experience of tech companies in the USA bay area; to attract talent, they offered amazing facilities so that staff were excited to go there. The driver became about the people/occupants rather than the real estate department.
JP The purpose of the office is changing; it’s less about ‘processing’, more about developing ideas with others. The ‘seed’ of an idea can happen anywhere, but working together is the way an idea is developed and implemented.
AB Professional Designers can add value by helping clients make small changes that can become big changes. The ‘new normal’ is not yet defined, but we can build in flexibility to allow change as we move towards ‘blended’ working approaches.
CB Perhaps more than ever ‘design’ will become ‘Social Engineering’!
JP In the ‘olden days’, it was generally the smokers who were regarded as the most creative. They would regularly ‘break out’ for a cigarette and chat, so they knew everything that was going on. There may be lessons here...
CB Right now, the day you move in, your office won’t be finished. It will have to adapt and change further.
AB In the face of uncertainty, costs may be considered a barrier to doing anything now. But think about the costs of NOT doing anything.

Designing the experience of the future workplace, chaired by Daniel Gava

Natasha Bonugli, Founder and Creative Director,The Bon Collective
Erik Behrens, Creative Director, AECOM

What’s your personal experience of going back to the office?

NB A realisation that we need to coordinate with others and be organised about being in the same place at the same time. There’s little point going back just to sit by yourself!
EB AECOM were already set up with flexible offices and working practices before lockdown, so personal impact has fortunately been minimal.

What do you think will change in practice?

NB The office must become more ‘user-centric’, giving choice and control so that occupants can select work settings appropriate to the task at hand. Not everyone works well at home. Smaller clients are already trying to provide ‘what staff want’; but larger businesses seem to be taking pause
EB ...and perhaps we don’t want the office to be ‘like home’ at all. For example, Facebook USA provides a complete Campus experience, including accommodation.
NB But the working environment (like clothing standards) will probably become more casual; there may be implications for furniture designers.
EB And we need to think more ‘out of the box’ – ‘Breakout areas’ alone don’t really do it. As an example, people may choose to meet in a restaurant, which is a different mindset. The office is not typically the best place to ‘seed’ ideas; they often come away from work; perhaps at night or while travelling.
NB In practical terms, there will be more smaller meeting rooms /areas with well-integrated technology
EB Also more customisation, rather than using ‘off-the shelf’ products (also more sanitisation of shared facilities)
NB ‘The Evolution Workplace’ is emerging, we are beginning to see retail space converted to workspace; the term ‘office’ may gradually lose relevance
EB Yes, on a larger scale, we may see tower offices separated in to living/working/parking floors – perhaps even towers connected by sky bridges.
EB In the future, society will judge ‘Corporate Success’ differently; People, Planet and Personality rather than just ‘Profit’.
NB ...and don’t forget ‘Place’!

Expert Views – Conclusions

Appropriately, none of the experts claimed to know it all, but all agreed that a ‘place’ of work is fundamental to corporate success and employee wellbeing.

It was broadly suggested that the corporate winners will be those who are prepared to embrace some changes now, as a step towards a blended work future. The cost of not doing so could be greater than doing nothing, if there’s a desire to attract and retain the best talent.

Along with this we may see changes in appearance from ‘formal off the shelf’ to ‘casual and customised’. Potentially we’ll develop a new understanding of what the workplace is; certainly not ‘just’ an office.

Studio Pringle is soon to publish ideas for an ‘interim interior’ - an approach that will allow occupiers to accommodate future adaptations over time.

The Exhibitors

This wasn’t the biggest show, but we admire the commitment and enthusiasm of all the exhibitors who took part. It’s they who effectively fund such shows, allowing attendees to benefit from the talks programme.

If the answer to the new workplace is ‘more acoustic booths’, we were spoilt for choice. For us, this highlighted something of a disconnect between what the experts are thinking about, and where the manufacturers are currently – not entirely surprising given the length of time typically required for product design and development.

However, in general it’s reasonable to assume that the balance of workspace will shift towards more spaces for meeting and interaction – and that these spaces will need to be easy to move or reconfigure, which is where booths have the edge over traditional partition walls. Not all meeting spaces can be acoustically isolated, so it was good to see attention being paid to more general acoustics treatments.

We were also pleased to note the commitment by some suppliers towards a sustainable future. Exhibitor Casala (See end of article) was particularly strong in this respect; we need more producers to consider not only use of recycled materials in production, but also end-of-life recycling and re-purposing.

Mute Design

Mute Design

Polish maker Mute was unfamiliar to us before this show, but we were immediately drawn to their attractive stand by their unique ‘Light wall’ screens, which include a hidden transparent acoustic barrier behind fabric slats (See header image).

As their name would suggest, Mute specialise in workplace acoustics, including sound-absorbent light fittings and panels – and of course booths! These booths appeared to be of very high quality, performance and appearance, available in a wide range of configurations.



Consistently innovating, Spacestor have been a staple feature of the workplace scene during lockdown. They have run a series of Webinars featuring leading experts from around the globe, and have made a real contribution to the debate.

At this show they introduced ‘Verandas’ – a recyclable steel-based framework from which can be created acoustically-enclosed and semi-open meeting and breakout spaces – a step beyond ‘standalone’ booths.

Table Place Chairs / Stansons

Table Place Chairs / Stansons

This fine collaboration has created ‘The Circle of Life’ - a less formal structured meeting zone, utilising strong curved steel sections hung with recycled plastic fabrics. Not acoustically isolated perhaps, but a comfortable and attractive environment for casual meetings. This was judged #1 Show Winner by the show’s expert panel.



A show regular, Abstracta have forged a reputation for providing innovative, high quality, workplace acoustic products. Their excellent plenty pod acoustic booth was displayed, along with some neat ideas like the dB Pillar acoustic display pole and the compact dB modular sofa



Agilita displayed a number of their compact meeting/breakout configurations, including this innovative ‘daybed’ pod / room divider called Relax



Buzzispace participated, although their stand could not convey the breadth and depth of their huge and sometimes quirky workplace acoustics offering. They featured the new BuzziCee lounge seating – nice to Cee you!



Allsfar make acoustic products with a felt material made from 60% recycled PET (from plastic bottles), 100% recyclable at end of life, so they score on the environment too. Their stand was deservedly busy!



Spanish manufacturer Actiu is strong on innovation and environmentally-friendly production processes (Their technology park is LEED and WELL Platinum Certified).

As an example, they displayed some bespoke version of the soon-to-be-launched Fluit chair, injection-moulded using recycled plastic pellets. Additionally, they have developed a unique sensor-based environment-monitoring system Gaia that can help Facilities Managers improve lighting and air quality, and help users to find an appropriate ‘agile’ work setting.



Casala really impressed – not only because of the warm welcome from Alex and Kim (that’s Alex in the photo), but because of their commitment to ‘circular economy’ principles from design & manufacture to end-of-life.

We began by looking at the Curvy stacking chair. A nice piece, and one of the strongest and most comfortable of its type we have seen - now available in a palette whose seat and back are made from 100% recycled plastic household waste.

Also featured was Capsule soft seating – elegant, beautifully detailed and space-efficient with good acoustic properties; available in a complementary form without the upper acoustic enclosure as Capsule Lounge.

Interion is a great partner for anyone interested in the workplace and ways of working; we empower our clients by sharing our knowledge and sourcing the most effective product solutions.
