Home renovation costs depend primarily on the scope of work, material quality, and the complexity of your existing space. Rather than a fixed price, budget is shaped by decisions made during Discovery and Concept — the earlier stages where you define what the space needs to become. Understanding these drivers helps you make choices aligned with permanence rather than trend.
Why renovation costs vary so widely between similar projects
Two homes of the same size and age rarely cost the same to renovate. The variation comes not from guesswork but from real differences in what each space requires. A residential project in London Embankment, for instance, carried different structural and specification demands than the Witham Project — same discipline, entirely different briefs. The studio’s process recognises this from the outset. During Discovery, the team assesses existing conditions, building fabric, services, and what the space must do. A kitchen with serviceable electrics costs less to alter than one requiring rewiring. A room with period features worth retaining drives different material choices than one suited to complete reinstatement.
Cost emerges from specificity, not generality. Specifying a handmade tile from a particular maker costs differently from factory production. Choosing to reupholster existing furniture rather than replace it changes the budget line entirely. Commercial projects like Beaulieu Dental Practice and Fruittii Hair Salon show this clearly — both retail and professional spaces, both requiring entirely different material resilience and cleaning protocols, therefore entirely different specification decisions. The studio’s approach front-loads these decisions in Concept, Design & Specification, where every material and finish is chosen for durability and appropriateness rather than initial cost alone.
What gets included in a typical home renovation budget
A renovation budget divides into labour, materials, and contingency. Labour is the professional time required to execute: architects, designers, contractors, specialists. Materials cover everything specified — flooring, joinery, lighting, soft furnishings, finishes. Contingency is money held for the unforeseen (a wall that needs additional support, a service that sits differently than drawings assumed). Most budgets fail because contingency is either non-existent or unrealistically small. The Witham Project and London Embankment Apartment both required real contingency funds; period properties almost always do.
What sits outside your renovation budget matters as much. Site clearance, structural surveys, building regulation approval, and moving costs are sometimes misplaced into the design fee rather than the works budget. Professional design — the Discovery, Concept, Design & Specification process — is a separate investment from construction. The studio works with clients to separate these clearly, so budget lines don’t blur and funds don’t get misallocated mid-project. Understanding what you’re paying for at each stage prevents discovering halfway through that ‘the renovation’ didn’t actually include what you thought it covered.
How material choices affect overall cost and longevity
Material selection is where quiet luxury differs from trend-led spending. A costly material chosen for fashion fails within seasons. A modest material chosen for durability and appropriateness outlasts cycles. Commercial projects like Keystones Estate Agent or Tone at Canary Wharf required finishes that handle traffic, cleaning, and daily use. The specifications reflect frequency of contact, not aesthetic trend. Residential work applies the same logic: a sitting room finish must endure years of domestic life, so the material choice reflects use, not social media.
The Concept, Design & Specification stage is where this rigour matters most. Here, the team specifies materials for their performance in your specific space, under your specific conditions, with your specific habits. A reupholstered sofa keeps its original frame if that frame is sound; the cost is reupholstery labour and fabric, not replacement. Wall finishes are chosen for patina and wear rather than sterility; some materials hide marks and settle beautifully, others show every fingerprint. These decisions compound over years. Spending more initially on a durable material often costs less than replacing a cheaper material within a decade.
Understanding the difference between design fees and construction costs
Many people conflate design with construction, asking “how much does a renovation cost” as though it were a single number. It isn’t. Professional interior design — the Discovery, Concept, Design & Specification work — is a service you pay for separately from the cost of building or installing anything. That design fee funds expertise: understanding your space, its history, its structure; proposing solutions; specifying materials and finishes in detail; managing relationships with makers and contractors; and overseeing quality during Commission and Reveal.
The studio’s portfolio shows why this separation matters. Projects like Beaulieu Dental Practice and Fruittii Hair Salon required design expertise specific to commercial environments: compliance, workflow, material performance under professional use. That knowledge has a cost independent of how much it costs to build the space. Without it, construction costs often exceed budget because unknowns emerge on site. With it, costs stay predictable because the work is defined before the first tradesperson arrives. When evaluating a renovation, ask for design fees and construction costs separately. One funds clarity; the other funds execution.
What questions to ask before committing to a renovation budget
Before settling on a budget, establish what the space must do and what condition it’s really in. A survey that identifies structural issues, damp, or service problems is money spent early that prevents costs appearing mid-project. Ask: are you retaining walls or reconfiguring the layout? Are existing finishes worth keeping or do they need complete renewal? What systems (electrical, plumbing, heating) are serviceable, and which need replacement? The answers drive cost far more than square footage does. A small bedroom requiring complete structural repair costs more than a large one that needs cosmetic finishing.
Clarity on permanence versus trend is equally important. Are you choosing finishes and materials because you love them and they suit your life, or because they’re currently fashionable? The distinction determines how soon you’ll feel the need to change again. The studio’s approach — grounded in Discovery and Concept phases where your actual needs are understood — produces interiors that age well because they’re built on use and preference, not trend. Before agreeing to a budget, work with a designer who will ask what the space needs to become, not what it needs to look like this season. That clarity saves money and prevents regret.
How to manage renovation costs without sacrificing quality
Cost control isn’t about buying cheaper; it’s about choosing wisely. Prioritise. A kitchen renovation with a modest budget works better with excellent specification and real materials in high-touch areas (worktops, handles, taps) and simpler solutions elsewhere. Reupholster a beloved sofa rather than replace it. Retain existing joinery if it’s structurally sound and only refinish it. These decisions are made during Concept, Design & Specification — before any money is spent on materials or labour. Once you’re in Commission, changes cost far more.
Phase the work. A complete renovation in one go maximises disruption and can inflate costs through compressed timescales and contractor availability. Phasing allows you to spread investment, learn what works in each completed space, and refine priorities for later phases. The studio’s process is designed to support this: Discovery and Concept can encompass the whole home, but Concept, Design & Specification and Commission can target one area at a time. This approach keeps budgets manageable and decisions grounded in reality rather than speculation about future needs.
