Understanding the role of an Interior Designer

An interior designer’s role is multi-faceted, but begins with providing accurate and professional advice for the development and execution of interior design services across the commercial contract or residential sectors. An interior designer can provide initial design concepts and space planning proposals, product and material specifications, as well as coordinate with intersecting trades to manage a project from concept to completion. This can include duties like:

  • Providing advice on the interior layout of a space/building and proposing reconfigurations.
  • Generating 2D or 3D interior design plans, drawings, mood boards and project visualisations.
  • Curating a considered selection of Furniture, Fixtures and Fittings (FF&E) required for implementation and procurement.
  • Supplying projected timelines and product schedules to coordinate trades, purchase orders and deliveries.
  • Being the point of contact for construction contractors on site, as well as consulting with engineers, architects and trade specialists.

The main goal is to improve the effectiveness, accessibility, functionality and aesthetic appeal of an environment in a way that ensures the safe and optimal occupation and use of the interior space. An interior designer will consider the intended function of a space to curate an environment that is fit for purpose, as well as understand how an interior design scheme can positively impact the end-user. A successful design project will also address sustainability and minimise its environmental impact.

With differing laws for product use and specification across residential and contract sectors, an interior designer must be aware and comply with all related health & safety codes, building regulations, and installation requirements.

Assessing the impact of an interior design

As a designer’s choice directly impacts on the wellbeing and safety of those who will use or occupy an interior dwelling, the advice offered must be accurate and where necessary, independently verified to support recommendations. Inaccurate advice and inappropriate specification may breach laws, incur additional cost, generate delays or increase risks to those who invest in and ultimately use the space.

For example, when a provisional costs price (PC) is quoted for a light fitting, additional costs may be necessary for the designer to instruct the expert and obtain independent advice to be confident that the design specification is compliant, as well as safe.

Providing the interior design service

An interior designer’s minimum task is to define the design and ensure the safe performance of a space. They should plan the space to maximise the function and movement within it, as well as taking airflow, heat, extraction, electrical and plumbing regulations into account. They produce plans and drawings to demonstrate layouts (spatial planning) along with a proposed design scheme. When the scheme is approved by the client, the designer generates a project timeline and specification schedules for the materials required to procure the design. Some designers may also act as the project manager throughout project procurement by giving instructions to the contractors, trade and fit-out specialists.

Consulting with specialist stakeholders

An interior designer is not only an advisor to the client, but often, to other industry professionals on site. Designers may be expected to coordinate with various experts, tradesmen and suppliers in their procurement of products and installation of materials. For example, they may consult with a structural engineer when commissioning a light fitting or require asbestos reports before fitting wall paneling. A designer must therefore possess knowledge across a multitude of skills and sectors.

This multi-faceted profession requires specialist expertise across all stages of design and project fulfilment. With evolving regulations, product innovations and compliance laws, designers must invest in ongoing learning to stay up to date with industry standards.

The distinctions within the profession of interior design:

International differences in the role of an Interior Designer

In many countries, the title ‘Interior Designer’ refers to the skills and remit of what the UK describe as an ‘Interior Decorator’. The confusion relates to protection of title. In Europe, an Interior Architect describes the same remit and skill of a British interior designer, but as ‘Architect’ is a protected title in the UK it cannot be used to describe an interior designer. Descriptions of the role and skills of interior designers differ around the world, unlike that of an Architect, Lawyer or Doctor where the title is clearly identified.

SBID aimed to clarify the role and definition by identifying the various sector specialisms within interior design that require specific compliance laws. A clear understanding of roles and obligations is core to the teaching structures and course content which trains new professionals. SBID continues to work towards title recognition for an Interior Designer in the UK.
