7 ID Firms in Singapore That Mid-Century Modern Fans Should Check Out

For good design that never goes out of style.

There’s plenty to like about mid-century modern (MCM) interior design: It’s clean, stylish, and most importantly, timeless. Despite having its roots in the mid-1940s, this aesthetic still enjoys popularity today, mostly thanks to its iconic design characteristics that appeal to – dare we say it, modern sensibilities.

And if you’re a homeowner who’d love a highly sophisticated dwelling filled with natural wood textures, classic furnishings, and yesteryear charm – then look no further. Below, we share our list of Singapore-based interior design firms that feature appealing MCM homes in their portfolio!

1. The Local INN.terior

While The Local INN.terior does have a wide range of styles covered in its portfolio, its signature look (at least in our opinion) leans toward the mid-century modern aesthetic.

By that we mean charming spaces that pair warm wood and earthy tones with organic lines and restrained pops of colour, nodding to the mid-20th century without feeling out of place in 2026.

Comprising creatively-fuelled and attentive designers, the firm has won multiple industry awards and garnered over 300 5-star reviews on Qanvast, lending assurance that your MCM-style dream home will be in good hands.

2. Insight.Out Studio

From the get-go, Insight.Out Studio’s slogan “Born from imagination, built with intention.” is very much in line with the MCM movement where form follows function.

It stands true to its nature as a boutique firm, where no two projects in its portfolio look the same. Instead, each is well-thought out to not only look good, but also to ensure that its owners feel truly at home.

Additionally, the firm promises the use of premium materials and quality workmanship (after all, MCM homes are meant to stand the test of time). Many of its past clients attest to this, resulting in a stellar 4.9-star rating on Google as at time of writing.

3. Fifth Avenue Interior

Always on-trend but never cookie-cutter, Fifth Avenue Interior is known for its artistic solutions that turn regular spaces into stunning homes. Much like the mid-century modern aesthetic, its designs feel understated yet enduringly elegant.

Clients frequently praise the team for their fresh ideas, professionalism, and timely handovers – qualities that are important whether you’re going for a classic (and classy) MCM look, or something that’s a little more fun with an eclectic touch.

Plus, rest in the knowledge that the firm draws from a wealth of experience, having renovated over 1,500 projects to date.

4. Authors • Interior & Styling

As their name suggests, the team at Authors sees themselves as 'co-authors' with their clients in using intertwining design concepts to create a strong visual narrative.

In the case of its MCM projects, this frequently comes across through a curated mix of natural materials, low-profile furniture with tapered legs, and the occasional accent to make a statement.

Practically, this narrative begins with an open exchange of ideas. The firm’s designers take the time to understand each homeowner’s vision, before offering their expertise to elevate and refine initial concepts.

Notably, many of its reviews indicate that renovating with Authors is by and large a stress-free process – a ‘green flag’ to look out for, if you ask us.

5. SG Interior Design

If you’ve been following Singapore’s interior design scene on social media in the last couple of years, chances are, you’ve come across SG Interior Design.

They’re known for creative spatial planning, attention to colour and textures, as well as detailed woodwork.

Some reviews even indicate that their IDs go the extra mile to recommend specific loose furnishings, or go furniture/material shopping with clients to ensure visual cohesion with the rest of the space.

Given that MCM interiors rely heavily on wood, organic textures and the right loose furnishings, these are definitely good qualities to look for in an ID.

6. Ascend Design

MCM interiors are full of character, and we reckon that’s an apt description of Ascend Design’s works – with many reviews lauding its designers for having a strong aesthetic sense.

Far from formulaic, each project comprises a thoughtful and unique blend of clean lines, curves, well-placed accents, and a variety of textured surfaces. Together, each vignette looks like something out of a magazine, and the kind of space that would turn anybody into a homebody.

7. Le Interior Affairs

With bold MCM designs that evoke emotion through balance, warmth and ease, Le Interior Affairs undoubtedly earns its spot in the list.

We also like that they don’t follow the ‘textbook’ definition of the MCM style. Some projects adopt an avant garde monochromatic feel, while others are more vibrant, according to the owners’ preferences.

In the words of one of its past clients, “Every space feels intentional, comfortable, and personal.” Now that sounds like home.
