What does interior design actually involve, and how do studios approach it?

Interior design is a structured discipline that moves through Discovery, Concept, Design & Specification, Commission, and Reveal stages. Each phase serves a specific purpose: understanding the space and its users, developing a visual and functional strategy, detailing every material and specification, overseeing execution, and delivering the finished interior. The work combines spatial planning, material knowledge, and project management to create interiors that function and endure.

Why does interior design begin with Discovery, not sketches?

Interior design studios that prioritise longevity start with Discovery: a thorough understanding of the space, its users, and its constraints. This phase is where the brief is tested, the building’s existing structure is evaluated, and the client’s genuine needs are separated from assumed wants. Without this foundation, subsequent decisions lack logic and often require rework.

In commercial projects like Beaulieu Dental Practice and Fruittii Hair Salon, Discovery revealed the operational rhythms of each space: how practitioners move through it, where patients or clients spend time, what materials withstand daily use. In the London Embankment Apartment, Discovery established how the residents actually lived in the space across seasons and daily routines. This information shapes every decision that follows, making the Concept phase purposeful rather than decorative.

What happens during the Concept phase?

Concept translates Discovery findings into a visual and functional strategy. This is where the studio establishes the spatial hierarchy, material palette, lighting approach, and the underlying logic that will guide every specification. The Concept is not a mood board; it is a coherent system that explains why each element exists and how it serves the brief.

At Keystones Estate Agent, the Concept established how the interior would communicate the brand’s positioning while functioning as a working environment. At Tone at Canary Wharf, the Concept balanced commercial function with the refined aesthetic appropriate to its location and clientele. The Concept becomes the reference point for the Concept, Design & Specification phase, ensuring that every material, finish, and detail aligns with the underlying strategy rather than accumulating as isolated choices.

What is Concept, Design & Specification, and why does it matter?

Concept, Design & Specification transforms the Concept into a complete, buildable specification. This phase details every material, finish, dimension, fixture, and installation method. It includes technical drawings, material samples, colour specifications, and supplier information. The specification is the document that contractors, makers, and suppliers work from; its precision directly affects the quality of execution and the durability of the finished interior.

Specification is where material knowledge becomes essential. A reupholstered sofa keeps its original frame but gains a new life through fabric choice, seam detail, and construction method. A wall finish is selected not only for appearance but for durability, cleanability, and how it performs in the specific environment of that space. In the Witham Project, specification ensured that every surface, from flooring to joinery, was chosen for both aesthetic coherence and long-term performance in a residential setting. This is the phase where cost-value becomes clear: cheaper materials often require earlier replacement, whereas durable, appropriate choices perform for years.

What happens during Commission and Reveal?

Commission is the execution phase. The studio oversees the realisation of the specification: materials arrive, contractors install, details are verified on-site, and adjustments are made where reality meets the specification. This is where coordination, problem-solving, and attention become visible. A well-managed Commission prevents costly delays and ensures the finished interior matches the specification’s intent.

Reveal is the moment when the interior is handed over complete. This is not the end of the studio’s relationship with the space; it is the beginning of its life. The interior should function as specified, feel coherent in the way the Concept intended, and respond to the genuine needs identified in Discovery. In commercial projects like Fruittii Hair Salon and Beaulieu Dental Practice, Reveal meant a space that works operationally and creates the intended environment for its users daily. In residential projects like the London Embankment Apartment and Witham Project, it meant a home that reflects how its residents actually live.

How do studios balance aesthetic and function?

The best interiors do not separate aesthetics from function; they arise from the same reasoning. An aesthetic choice that ignores function will fail quickly in daily use. A purely functional approach that ignores how a space feels will fail its users emotionally. The studio’s role is to develop a strategy that serves both, where every decision has a reason and every reason is grounded in the brief.

Commercial spaces have different demands than residential ones. At Keystones Estate Agent, the interior needed to function as a sales environment while communicating professionalism and trustworthiness. At Tone at Canary Wharf, the brief required that the space perform commercially while maintaining refinement. The Witham Project and London Embankment Apartment, by contrast, needed to function privately and intimately. In each case, the aesthetic emerged from understanding the specific purpose and users of the space, not from applying a universal style.

What should you expect when working with an interior design studio?

A studio that works through Discovery, Concept, Design & Specification, Commission, and Reveal is transparent about its process and grounded in evidence. You should expect clear communication about what each phase involves, regular feedback on progress, and specifications that explain why choices have been made. The studio should be able to reference completed projects and discuss how similar briefs were approached.

Choose a studio whose work aligns with your project type. A studio experienced in commercial projects like Fruittii Hair Salon and Beaulieu Dental Practice has developed knowledge specific to those demands. A studio experienced in residential design, such as the London Embankment Apartment and Witham Project, understands how homes need to perform across time and seasons. The permanence of the finished interior depends on this expertise being applied systematically from Discovery through Reveal.

Common questions

What is the difference between interior design and interior decoration?

Interior design involves spatial planning, material specification, and systematic project management across Discovery, Concept, Design & Specification, Commission, and Reveal. Interior decoration typically focuses on aesthetic choices within an existing space. Interior design solves problems; decoration adds finishes.

How long does an interior design project take?

Timeline depends on project scope, complexity, and build schedules. Commercial fit-outs like Keystones Estate Agent and Fruittii Hair Salon involve different timescales than residential projects like the Witham Project. The studio establishes realistic timescales during Discovery and manages them through Commission.

Why does a studio need to spend time in Discovery rather than moving straight to design?

Discovery establishes the brief’s genuine requirements, the space’s constraints, and how the interior will be used daily. Without this foundation, design decisions lack purpose and often require costly revision. Discovery prevents later changes and ensures the finished interior serves its users effectively.

How do you know if an interior design studio’s work is appropriate for your project?

Review completed projects in your sector: commercial, residential, or specialist sectors. Examine how the studio discusses its work and its process. A studio experienced in residential projects like the London Embankment Apartment and Witham Project has specific knowledge of how homes perform over time. Commercial experience at Fruittii Hair Salon or Beaulieu Dental Practice demonstrates operational understanding.
