9 Best Luxury Interior Design Firms in Singapore (August 2026)

Before the list, the things that actually separate a luxury firm from an expensive one. The first is architectural capability. High-end homes, especially Good Class Bungalows and large landed properties, involve the building as much as the interior, so you want a firm that either has architecture in-house or collaborates closely with an architect and a BCA-licensed builder. On the planning side, GCB areas are gazetted and tightly controlled by the Urban Redevelopment Authority (URA), so experience navigating those rules matters.

The second is craft and sourcing. Luxury lives in the details: bespoke joinery, book-matched stone, specialist finishes, curated lighting and furniture. Look for firms with in-house or trusted artisan capability and a track record of sourcing the rare and the custom, because that is where a genuinely high-end result is made or lost.

Then judge them on portfolio and discretion. Look for completed homes at your level and in your aesthetic, whether that is understated and timeless or richly opulent, since luxury is not one style. Look for a considered, personal process, because at this level you are commissioning something bespoke and will work closely with the designer for many months. And weigh awards and press as signals of peer and editorial recognition. This is a shortlist to meet in person, matched to your taste and your home.

Luxury spans a huge range, because the material and craft decisions do. A high-end condo interior is one level, a large landed home another, and a full Good Class Bungalow something else entirely. Here are the ballpark 2026 ranges I would budget for, covering design and renovation, before furniture, art and consultant fees.

At this level, bespoke joinery, imported stone, specialist finishes and custom furniture are the main cost drivers, and structural or A&A work on a GCB adds architect, engineer and builder fees on top. Scope and specification, far more than square footage alone, decide where you land in these ranges.

Here is the shortlist in one view, by what each firm does best at the high end.

Luxury firms are often boutique or project-based and rarely appear on consumer review platforms, so I judged them on award history, published and press-featured projects, and the calibre of homes they have delivered, rather than star ratings, and I said so where a public rating simply does not exist. Details were accurate when I wrote this but they move, so confirm scope, credentials and the firm's architect and builder arrangements directly before you engage anyone. I update the list when my view changes.

There is no official line, but in practice luxury projects are defined by bespoke rather than package work: custom joinery and furniture, high-grade and imported materials, specialist finishes and lighting, and a highly personalised design process. They tend to be Good Class Bungalows, large landed homes, penthouses and premium condos, where the budget allows the designer to commission and source rather than select from a catalogue. The mark of true luxury is craft and coherence, not just a high price tag.

A Good Class Bungalow, or GCB, is the most exclusive class of landed housing in Singapore, located within gazetted GCB Areas that carry strict planning controls set by URA covering plot size, height and site coverage. Renovating or rebuilding one typically requires an architect and a BCA-licensed builder alongside the interior designer, because the works engage planning approvals and structural design. You want a firm that has genuinely worked within these constraints, which is why GCB experience is a specific thing to look for, not a given.

Usually yes. At the high end, design is a distinct professional service, and many luxury firms charge a design fee, sometimes as a percentage of the project value or a per-square-foot rate, separate from the construction cost. This buys you the concept work, detailed drawings, material curation and project oversight that define luxury work. It is worth clarifying the fee structure early, along with what is included, so you can compare firms properly and avoid surprises.

Start with portfolio fit: look for completed homes at your level and in your aesthetic, whether understated or opulent. Then assess craft and sourcing capability, since bespoke joinery and material quality are where luxury is delivered. For GCBs and large landed homes, confirm the firm has architectural capability and works with a licensed builder. Finally, meet them, because a luxury project is a long, close collaboration, and rapport and trust matter as much as talent. Awards and press are useful signals, but the completed work and the working relationship decide it.
