IID Architects







About Us

Initiatives in Design was established in 1984 as a partnership, becoming a limited company in 2007 trading as IID Architects. The practice is led by Directors Simon Tupper, Richard Matthews, Nick Rich, Gareth Box and David Brown, supported by 3 Associates.


IID Architects has a varied portfolio of community and education projects (including Higher Education) ranging from £500,000 to £30 million – we have extensive experience in conversion and extension of existing buildings as well as new builds.  We provide architectural services from inception to completion.


Since Alan Brown and Chris Box founded the practice, IID’s aim has been to provide a closely attentive and enthusiastic service to our clients, and to design imaginative, innovative and well-loved buildings.  These qualities have resulted in a number of successful and long lasting working relationships - some of which span 25 years – with Tiffin School, Haberdashers’ Aske’s School for Girls, Reed’s and Hampton School amongst others.

Project Direction / Management


We adapt our mode of working to suit different clients and project requirements – for larger BIM experienced contractors we adopt industry-standard procedures and established BIM protocols.  We’ve been using BIM software (Autodesk Revit) since 2001 and are now working on projects to BIM level 2.  We are committed to expanding our use of BIM to improve design and add value to our projects.

From the first meeting, our role is to ask the right questions, then listen and give careful consideration to the responses.  By applying our creative skills to what we have heard from and seen of the client, we are then able to address the project needs very exactly and use our expertise to realize the expectations of the client, the building’s users and the wider community


We value open communication, not only with clients, but across the design team and see our approachability and integrity as key strengths of the practice.


In design terms, quality is monitored by internal Design Quality Reviews during which each project is examined by members of the practice not involved in that particular design team.  They are able to question the project criteria and bring an objective eye to the development.


External monitoring takes place via our third party accreditations – ISO9001, CHAS (Contractors’ Health and Safety) and Constructionline.  We are an RIBA Chartered Practice.


We believe strongly in a team ethic as being the most effective way of achieving the best outcomes in project terms.  Our open plan studio and non-hierarchical management ethos contribute to a truly collaborative approach to design.

Corporate Responsibility

IID Architects runs a Work Experience programme which sees approximately 10-12 students every year spending two weeks working with us – as well as learning design and presentation skills and having some training on our building design software, students have the opportunity to join live projects, team meetings and generally to find out about a career in design.


By hosting work experience students from schools and universities and ensuring their time with us is spent profitably, we are putting something back into our local and professional communities.  This contributes to the development of the future workforce, helps us gain an insight into the current education system (which feeds back into our work) and develops our own staff by encouraging them to mentor/coach young people.


In 2016 we also became involved with the RIBA Architectural Ambassadors scheme, a schools programme which arranges for architects to collaborate with teachers and then go into schools to run design workshops with the aim of inspiring children about the importance of a well-designed built environment.


With regard to wider social responsibility we support those within the practice in their personal charitable initiatives (particularly the annual Swimathon for Marie Curie Cancer Care and Maggie’s London Night Hike).  As a practice we also support a selection of local and national charities.


IID’s approach to sustainability has developed and refined over 30 years of practice and is applied from the outset of a project:


  • The site and its context are carefully considered so as to make the best use of them through a coherent development strategy.
  • Phases of work are planned to eliminate unnecessary building or refurbishment.
  • We use Sefaira to help us design comfortable and energy efficient environments. This software allows us to optimise a building’s shape, materials and fenestration at the concept stage, creating spaces which have plenty of natural light but won't overheat on a summer's afternoon.
  • Suitable, cost-effective systems and technologies are selected as appropriate for each client.

Hampton Pre Prep and Prep School

We are also working to reduce our environmental impact as a business. This includes:


  • promoting the use of public transport, car share and cycling within the practice
  • holding meetings via web conferencing where appropriate
  • reducing energy and paper usage in the office and recycling waste.


Ensuring the practice adheres to its environmental principles is the responsibility of the Sustainability Group. As well as setting objectives and monitoring performance both within the office and on our projects, they ensure that everyone is kept up to speed with the latest issues and technologies through our CPD programme.
