Interior decorating costs depend on project scope, space size, material quality, and whether you’re redesigning a room or an entire property. A studio charges based on the complexity of the Discovery, Concept, Design & Specification, Commission, and Reveal process, not a fixed rate per square metre. Understanding what drives cost helps you budget realistically.
What actually determines the cost of an interior decorating project?
Interior decorating cost is shaped by five core factors: the size and number of spaces being designed, the depth of refurbishment required, the quality and provenance of materials and finishes, the complexity of sourcing and coordination, and the length of the project timeline. A single-room refresh differs fundamentally from a whole-property redesign. A commercial project like Beaulieu Dental Practice or Fruittii Hair Salon demands different expertise and scheduling than a residential apartment like London Embankment. The studio works through five defined stages—Discovery, Concept, Design & Specification, Commission, and Reveal—and the cost reflects the work required at each stage.
The materials you choose carry the largest cost variable. Reupholstering an existing sofa keeps the original frame and structure intact, lowering cost compared to purchasing new. Selecting paint finishes, wall coverings, or stone for kitchen and bathroom surfaces each carry their own investment brackets. Bespoke joinery, lighting design, and soft furnishings add layers of specialisation that increase the overall budget. A project specifying locally available, off-the-shelf components will cost less than one sourcing materials from specialist makers or importing finishes.
How does project type affect what you’ll pay?
Residential projects and commercial projects operate under different constraints and therefore different cost structures. The Witham Project and London Embankment Apartment are residential, where the priority is creating a home that suits the occupant’s life over many years. Commercial projects like Keystones Estate Agent, Tone at Canary Wharf, and the salon and dental practice work to different timelines, compliance requirements, and durability standards. A hair salon, for instance, must withstand daily heavy footfall and frequent cleaning; a dental practice requires material choices that support clinical standards. These functional demands affect material selection and therefore budget.
Residential projects often involve longer Discovery phases because the studio needs to understand how you live in the space—how you work, entertain, move through the home, what light enters at different times of day. A commercial interior might prioritise brand expression and client journey in tighter timeframes. Neither is cheaper or more expensive by type alone; the cost reflects the specific brief.
What happens during each stage of the process, and where does cost concentrate?
The Discovery stage involves site surveys, material sampling, and detailed conversation. This is where the studio learns what needs doing and what the space allows. Time invested here prevents costly mistakes later. The Concept stage distils these findings into a design direction, mood, and material palette. Concept, Design & Specification is where plans and schedules are finalised and every component is itemised and sourced. Commission involves placing orders, coordinating deliveries, and managing contractors. Reveal is the installation and finishing phase. Most cost sits in sourcing, material purchase, and realisation; less sits in the drawing and thinking stages, though those save money by preventing rework.
A smaller project might compress these stages. A whole-property project like London Embankment or the Witham Project extends across several months, with each stage building on the last. The studio’s fee covers the expertise and time at each stage, not a markup on materials. Understanding this separation helps you budget: you’re paying for knowledge and coordination, not inflated pricing on what you could buy yourself.
How does the size and condition of your space influence cost?
A studio apartment requires different investment than a four-bedroom house. A single reception room refresh costs less than redesigning a kitchen, bathrooms, and bedrooms. Older properties often need structural or systems work uncovered during Discovery; a listed building or Victorian terraced house may have planning constraints that affect material choices or installation method. A commercial space like Beaulieu Dental Practice or Fruittii Hair Salon requires services (plumbing, electrical, HVAC) that may need upgrading to support the new interior. These hidden costs only surface during proper site assessment.
Condition matters too. A space in good repair with sound walls, functional systems, and existing finishes in acceptable condition costs less to decorate than one requiring damp remediation, rewiring, replastering, or structural repair. The studio’s Discovery phase identifies these factors so you understand what the project truly entails before committing.
What should you expect to invest in materials versus design expertise?
Materials are typically the largest line item in any interior decorating budget. Flooring, wall finishes, soft furnishings, joinery, lighting, and fittings accumulate quickly. Design expertise—the studio’s time for Discovery, Concept, Design & Specification, Commission oversight, and Reveal coordination—is a separate investment that protects the material spend. A well-specified interior uses materials wisely and specifies them correctly the first time. Poor specification wastes material budget on duplicated orders, unsuitable finishes, or colours and textures that disappoint once installed.
The studio charges for the design process as a professional service. You are not paying inflated material markup; you are paying for the knowledge to select, source, coordinate, and oversee installation. This model separates what you spend on materials (which you control through your brief and priorities) from what you invest in expertise (which ensures the materials perform as intended and the finished interior is durable and cohesive).
How can you prepare a realistic budget before you start?
Begin by being clear about scope. Are you redesigning one room, several spaces, or the entire property? Do you need structural or systems work, or is this a cosmetic refresh? What is your timeframe? A project compressed into six weeks costs more to expedite than one planned over nine months. Once you understand scope, the studio’s Discovery phase quantifies what the space actually requires. You then know what you’re budgeting for, not guessing.
Prioritise what matters to you. If a new kitchen is essential and bedroom redecoration can wait, say so. If you have existing pieces you want to keep and refresh, that shapes material choices. If durability in a high-traffic commercial space is non-negotiable, that influences specification. The studio works with your priorities, not against them. A clear conversation about what you want to achieve and what matters most helps establish a realistic budget range before any commitment is made.
