Residential Architecture
Penthouses, condominiums and landed houses planned around how their owners actually move through a day. From schematic to keys, including bespoke joinery and lighting design.

Bespoke interior architecture · Singapore & Melbourne
A residence is a quiet argument for how its owners would like to live.
Orbiflex is a small atelier composing interiors that age generously. We take on twelve commissions a year — penthouses, landed houses, considered shopfronts — drawn slowly, built once, finished by hand.

What the studio offers
Three quiet practices, held under one roof
Drawing, building and finishing are not separate trades inside Orbiflex. They are the same conversation, rehearsed at three different scales.

Commercial Spaces
Boutique retail, hospitality and consulting rooms with the same material attention as a private home. Selected commissions per year; never volume.

How we draw
Three principles that survive every revision
i.
Material honesty
Stone is stone. Timber is timber. We rarely use finishes that pretend to be something else, and never on surfaces a hand will rest upon.
ii.
Plan before pattern
A floor plan that walks well does more for a home than any feature wall. We re-plan first, decorate last, and almost always remove a wall before adding one.
iii.
Patient lighting
A room is finished by light, not by furniture. We model every interior in three lighting moods — morning, working, dinner — before drawings leave the studio.
From first call to handover
A four-stage commission, transparently priced
Conversation
Two long meetings, on site if possible. We want to understand how you sit, cook, work and host before any sketch is made.
Schematic
Plans, elevations and a curated material board. You sign off on layout and palette before any detail drawings begin.
Documentation
Construction set, joinery and stonework drawings, lighting schedule and a single fixed price held to handover.
Build & finish
One project manager from our studio on site twice weekly. Snags are closed before keys; styling is the very last conversation.
In their words
From clients of the past four years
“We had been told by two other studios that the kitchen wall was load-bearing. Yuen Ren’s team brought a structural engineer to the second meeting and it took down in a week. The whole flat opened up.”— Audrey L., owner, Marina One penthouse
“The fixed price held all the way through. Not because nothing changed — plenty did — but because every change was costed and signed before it became a problem.”— Daniel & Pen V., Bukit Timah House
“They drew our shop in three weeks and it has aged better than the building it sits in. Visitors still ask about the limewash.”— Maeve C., Tanjong Pagar Atelier
“They flew over twice, sent the joinery in a single container, and assembled it onsite in eleven days. Genuinely impressive logistics.”— Jonas H., Toorak Villa
Honest answers
Six questions we are asked most weeks
How many projects does Orbiflex take on each year?
We accept a maximum of twelve commissions per calendar year so the principal designer can remain materially involved in every drawing, sample and site visit. The waitlist for residential commissions usually runs three to five months ahead.
Do you work on both new builds and renovations?
Yes. Roughly two thirds of our practice is renovation and re-planning of existing apartments, bungalows and shop interiors. The remainder is interior architecture for new builds, where we collaborate with the project architect from the schematic stage.
Is the design fee separate from the build cost?
We quote design and build as one fixed sum after the schematic stage. There are no quiet variation orders during construction; any change is presented in writing for your sign-off before it touches the budget.
Where do you work?
Our principal studio is in Singapore and we serve the central districts and East Coast. A second office in Melbourne handles selected Australian commissions for returning clients and a small annual roster of new ones.
How long does a residential project take from first call to handover?
A condominium of around 180 square metres typically runs nine to twelve months from brief to keys. Landed houses take twelve to eighteen months depending on permit complexity. We will give you a written timeline at the schematic stage.
Can I commission only the design, without the build?
Yes, we offer design-only engagements for clients who already have a trusted contractor, with optional site supervision packaged separately. Our drawings are detailed enough to be tendered as a complete construction set.
