Interior Design Services in Sydney: Scope, Cost and Fixed Fees
KAIKO DESIGN INTERIORS - EXPERTS IN COLOUR
Anyone planning a major renovation or new build in Sydney meets the same question early on. What does an interior designer cost, and what do you actually get for the money? It is a fair question, and a harder one to answer than it should be, because interior design is priced in several different ways. The figure quoted at the start of a project often bears little relation to the figure paid at the end.
This article sets out how residential interior design is priced in Sydney, what a full-service engagement involves, and why Kaiko Design, a Sydney interior design studio, works to a fixed fee rather than an open-ended hourly rate. The aim is to answer the cost question honestly, so you can judge whether the studio suits your project before you make an enquiry.
The scope of a full-service engagement
The term "interior design" covers a wide range of involvement. At one end, a decorator chooses finishes and furniture for a room that is already built. At the other, a designer shapes the entire project, from how the spaces are planned through to the last detail of the joinery. Full-service residential design sits firmly at that second end.
A full-service engagement runs from the first concept through to handover. It covers spatial planning and how you move through the home, the selection of materials, finishes and colour, the detailed design of kitchens, bathrooms, joinery and lighting, and a complete set of drawings and schedules that the builder works from. The studio stays involved through construction, answering the questions that arise on site and protecting the design intent as the home is built.
This breadth is deliberate. Most of the cost, and most of the risk, in a renovation sits in the decisions made before a tradesperson lifts a tool. A missing dimension, an unresolved junction, a finish specified late and ordered in a rush: these are where budgets slip and outcomes disappoint. Meticulous documentation is the antidote, and it is central to how the studio delivers full-service residential interior design.

How interior design is priced in Sydney
Three pricing models are common in Sydney, and they behave very differently over the life of a project.
The first is an hourly rate. It sounds transparent, but it leaves the total cost open-ended. Every call, revision and site visit adds to the bill, which quietly discourages the back-and-forth that good design depends on. It also penalises thoroughness, because the more carefully a designer works, the more the client pays.
The second is a percentage of the construction or project cost. The difficulty here is the incentive. When the fee rises with the build cost, the designer earns more each time the project becomes more expensive. That is precisely the wrong alignment on a job where the client is trying to spend well, not simply spend more.
The third is a fixed fee, which is how this studio prices its work. The scope is defined at the outset and the fee is agreed before the project begins. You can read how our fixed fees work in detail, but the principle is straightforward. A fixed fee takes the meter out of the relationship. Clients can call, question and refine without watching a clock, and the studio has no financial reason to inflate the build. The only incentive that remains is to get the project right and see it through.
A fixed fee suits a serious renovation or new build particularly well. Those projects involve hundreds of decisions across a long timeline, and certainty about the design fee lets you plan the rest of the budget with confidence. The studio sets its fees against defined scope rather than quoting a single number, because the fee reflects the size and complexity of each project. What it will never do is change halfway through because the hours ran on.
The value behind the fee
Value at this level is not measured by spending less. It is measured by getting the outcome right, in a home you will live in for years. A few things set the studio's work apart.
The first is documentation. A complete, coordinated set of drawings gives the builder a single source of truth, reduces variations and guesswork on site, and produces a home that resolves properly at every junction. It is the least visible part of the service and one of the most valuable, and it is where a well-run project quietly saves the money that a poorly documented one loses.
The second is a colour-led and deeply personal approach the studio calls dynamic eclecticism. Rather than follow a passing trend or apply a single house style, the studio designs around the people who will live in the home and the character of the building itself. Colour is used with intent, layered and considered, so the result feels timeless rather than dated within a few years. This sits at the heart of the Kaiko Design approach, and it is what makes each project specific to its owners.
The third is simply that the whole process is handled properly, end to end. One studio holds the project from concept to the final styled room. Nothing falls between disciplines, and there is a single point of responsibility throughout. For a client giving up months of their life to a build, that continuity is a large part of what the fee buys.
The projects the studio takes on
The studio works on whole projects rather than isolated rooms. In practice that means full home renovations, new builds, and apartment renovations where the entire interior is being reconsidered. These are projects with genuine scope, undertaken by people who want the process managed rather than pieced together.
The clients the studio suits are usually homeowners undertaking a significant, considered project: executives, lawyers, finance professionals and business owners who value expertise and want the work done once, and done well. A strong engagement starts with a clear conversation about the project, the site and how you want to live in the finished home. If you are weighing up how to approach that first step, it is worth understanding how to brief an interior designer before you begin, so the studio can give you the sharpest possible read on scope and fee.
Apartment projects sit comfortably within this. Considered apartment interior design can transform how a smaller footprint lives, and the studio approaches these with the same rigour as a full house. What falls outside the studio's focus is the single room or single space, a standalone bathroom or a patio in isolation. The value the studio offers comes from shaping a whole home, and one-off pieces of work are better served elsewhere.
Where the studio works
Kaiko Design works with clients across Sydney, with a particular presence in the Eastern Suburbs, the Lower North Shore, the Upper North Shore and the North West. These are areas of established homes, period houses and considered apartments, the kind of buildings that reward careful renovation. Wherever a project sits, the studio's involvement is the same: full-service, fixed-fee, and seen through from concept to completion.
Starting a project with the studio
If you are planning a renovation or a new build and want a clear sense of scope, cost and approach before you commit to anything, the sensible next step is a conversation. You can start a conversation with the studio about your project, your home and what you are hoping to achieve, and take it from there.
