Judge the firm before you judge the price
Choosing an interior design company in Hong Kong (室內設計公司) usually starts the wrong way round: people open with “how much?” and let the lowest number decide. But the cheapest quote from a firm you cannot rely on is the most expensive mistake in renovation. The better sequence is to shortlist firms on how trustworthy and capable they are first, then ask two or three of them for a price. Here are the six criteria that actually separate a firm you can hold to its word from a nice portfolio, and the two documents to ask for before you sign anything.
1. Portfolio relevance, to your kind of flat
A beautiful portfolio proves taste, not fit. What you want to know is how many projects in the last three years resemble your unit type and size, a compact private flat, a village house, a specific estate layout. A firm brilliant at 2,000 sq ft show flats may have never solved the storage-and-circulation puzzle of a 400 sq ft unit. Ask, specifically, to view completed projects in person, not just photographs. Photos are lit and styled; a real home tells you about the workmanship.
2. Licensing, held in-house or named as partners
Depending on the works, a project may need licensed professionals: an Authorised Person (AP), a Registered Structural Engineer (RSE), a Registered Electrical Worker (REW), and clearances such as Fire Services or building-management consents. A design firm needn’t hold every one of these in-house, but it should be able to name the partners it works with and speak clearly about which your project needs. Vagueness here, on works that clearly require a licence, is a warning in itself.
3. Contract type, design-only or design-and-build
This one decides who is accountable when reality meets the drawing. A design-only firm hands you drawings; you then appoint and manage a contractor yourself. A design-and-build company keeps both under one team, so there is no gap to fall through when something on site doesn’t match the plan, one party owns the outcome. Neither is wrong, but they place the coordination burden very differently. Ask plainly which model a firm offers, and be honest with yourself about how much of the build you want to project-manage.
4. Communication, who is your day-to-day contact
Find out who you will actually deal with, day to day, and whether the same team carries the job from design through to handover or hands off to a separate party partway through. A designer who charms you at the pitch but disappears once work starts is a common source of regret. Ask, too, how variations are handled, the moment you change your mind mid-build is exactly when a firm’s communication discipline shows.
5. Warranty, scope, duration, and what voids it
Ask for the warranty document up front, and read three things: how long it runs, what it actually covers (workmanship versus procured products, these are different), and what voids it. A dramatic-sounding, sweeping warranty that no one will put in writing is marketing, not cover, as the trade saying goes, an impressive-sounding structural warranty is usually unbacked. A modest warranty you can hold in writing beats a grand one you can’t.
6. A public, verifiable trail
The simplest test of all: can you actually find them? A fixed, verifiable business address, a real showroom or office you can visit, completed projects you can see in person, a traceable public presence. A firm reachable only by a mobile number and a handshake has left nothing to hold it to. This single check filters out most of the worst outcomes.
Get two to three quotes, and two documents up front
Once you have a shortlist on those six criteria, get two to three quotes, fewer than two gives you nothing to compare, more than four becomes admin chaos and the quotes blur together. Aggregator platforms can be useful for gathering those first quotes, but remember the relationship that actually matters is the firm you sign with, not the platform that introduced you. And before you commit, ask every shortlisted firm for two documents: the warranty document and a sample contract. A firm that shares both without fuss is telling you something good; one that stalls is telling you something too.
Watch for the red flags while you assess
The flip side of these six criteria is a short list of warning signs, a large up-front payment, a vague quotation, no written contract, no fixed address, and two or more is a reason to walk, however good the portfolio; the full pattern and how to read it is in our guide to avoiding renovation scams.
How Primeworks handles this
We are built to answer these six criteria plainly rather than deflect them. We design and build under one team, so accountability sits in one place from first sketch to handover, and your day-to-day contact stays consistent throughout. Our quotations are itemised, our terms are written with clear scope and exclusions, and payment is staged against on-site progress rather than demanded up front. We are happy to share a sample contract and our warranty terms before you commit, because being easy to vet is the whole point. That transparent, staged model is how we deliver affordable luxury (靜奢，觸手可及) without asking you to take anything on trust.
