Interior designer at TRiARA Residences
A home you can open up.
Fewer walls or more rooms. The choice is yours.
Thoughtfully designed around the way you live, and what you’d like to spend.
Still waiting for your keys, and unsure where to start?
TRiARA Residences’ homes have three or four bedrooms, and every plan has walls marked to come out.
We help you decide which rooms your family needs and which walls should go, before anything is built.
We’re Sundays in Bed, a Kuala Lumpur studio that designs and looks after homes. TRiARA is still being built, so we haven’t designed a home here yet. When you’re ready, we can design yours for a fee per room, set out in writing before we begin.
TRiARA Residences is Sime Darby Property’s final high-rise with a residential title in Ara Damansara: 450 freehold homes in three blocks of 18 to 23 storeys, on 5.62 acres off Jalan PJU 1A/7.
- Towers A and CDue 2028Two blocks · 292 homes
- Tower BDue 2028One block · 158 homes
TRiARA homes come in three sizes, from 1,216 to 1,808 sq ft built-up.
- 1,216 sq ftThree bedrooms, two bathrooms (Type A, the most common)
- 1,507 sq ftThree bedrooms, a study, three bathrooms (Type B)
- 1,808 sq ftFour bedrooms, a study and a utility room (Type C, Tower B only)
The layout and storage
On the developer’s plans, each type has one wall marked “hackable”.
So the walls come first, before any finish. A wall taken down after the wardrobes are built is paid for twice, which is why we sit down over the plan with you early. We agree which walls go, and what every room is for, before a single cabinet is drawn.
The plans are drawn with three generations in mind: a wider front door, an elderly-friendly master bath with room to turn a wheelchair and, in Type C, a junior master with its own bath by the entrance. If grandparents may come to stay, we’ll plan for them from the start.
Who do you picture coming through your front door each evening?
We start with who each room is for and how your household cooks.
Those answers decide which walls stay, and the walls shape most of what follows.
If someone works from home
In Type B the study sits behind a hackable wall off the living room; in Type C, beside the third bedroom. Open it into a family room, or close it with a door for work. We’ll help you decide before the wiring goes in.
If the kitchen is where the family gathers
Every plan opens the kitchen to the dining, with a yard the developer marks for laundry and kitchen use. The frying can move out there, or a glass screen can close the kitchen. We’ll plan whichever suits how you cook.
If a grandparent may move in
Type C’s junior master sits by the front door with its own bath, the utility room beside it. For a grandparent we plan grab rails, a level shower and soft night lighting along the way to the bathroom.
If you love sitting outdoors
Each home has a full-width balcony with a water point and a power point: enough for planters, an outdoor light and a small table. We’ll treat it as one more room, within whatever rules the management sets.
What comes with your keys
These are new homes, so the bathrooms and the developer’s elderly-friendly details stay as handed over, and we design around them. We’ll spend first on the rooms your household will really change.
What will our fee be for designing your TRiARA home?
For a Type A three-bedroom, the Sundays in Bed design fee is estimated at RM16,180–23,310; for a Type B with its study, RM19,745–26,875; for a Type C four-bedroom with its study, RM23,310–30,440.
Your final fee depends on the rooms you choose, and is agreed in writing before we begin.
- Each room we design
- RM3,565
- Living and dining
- RM5,485
3 bedrooms: 3 rooms at RM3,565, plus the open-plan living and dining at RM5,485. The foyer and utility yard are designed free.
Within each level, the low end is the essentials; the high end adds extras such as a feature wall, LED strips and a kitchen island.
What the two levels mean
Curated. Melamine or laminate carpentry, quartz or sintered stone tops, the existing ceiling kept or a new plaster ceiling. Furniture from Commune, Cellini, Fella Design, Dezign District, Poet Living, Big Brain, Gudang, Crown Livin and Dadswood.
Bespoke. Detailed joinery, sintered stone tops, a plaster ceiling with detailing. Furniture from Space Furniture, Tekni, BoConcept, King Living, Ambient Living, Stanzo, Forest Furniture, Roche Bobois, XTRA, Urban Edge, Molteni&C, Nostaloft, Flexform, Janine and Chesters Collection.
How the fee works
The sum is set out in writing before any work begins, then paid in stages. Contractors’ charges don’t move it, so taking down a hackable wall or choosing stone worktops changes their bill and leaves ours as it was.
With our fee and Curated finishes (Commune, Cellini, Poet Living), a Type A here comes to about RM157k–283k in all.
Spend on the rooms you’ll change. At TRiARA that usually means wardrobes, the study and the kitchen, and rarely the new bathrooms. Set your type and tick only the rooms you want us to design. Fee and ranges stay estimates until contractors price the drawings.
| Home | Our fee | Curated | Bespoke |
|---|---|---|---|
| Type A 3-bed 1,216 sq ft | RM16,180–23,310 | RM141k–260k | RM300k–631k |
| Type B 3+study 1,507 sq ft | RM19,745–26,875 | RM152k–278k | RM319k–668k |
| Type C 4+study 1,808 sq ft | RM23,310–30,440 | RM171k–313k | RM355k–743k |
The lower figure is the usual TRiARA brief: the living and dining with its open kitchen, every bedroom and, in Types B and C, the study. The higher allows two more rooms, such as a bathroom or Type C’s utility room as a guest room.
These are October 2026 estimates; only your contractors can give quotations.
How these figures are worked out
At Curated, furniture comes from Commune, Cellini and Poet Living; at Bespoke, from Space Furniture, BoConcept and Molteni&C.
These homes are new, so no bathrooms are priced; count any you’d change. The study in Types B and C is priced as a designed room, and Type C’s utility room is left as it is.
The ranges assume new kitchen cabinets, a hob and hood, wardrobes, lighting and air-conditioners. TRiARA’s handover list hasn’t been published, so whatever comes with your keys and stays will bring the figure down.
Furnishing to let?
A lighter, hard-wearing fit-out at our Essential level, quicker to finish and easy to keep tenant-ready, is one possibility, with furniture from Ikea, SSF Home and Harvey Norman. The design fee is the same at every level.
Renovation and furniture at Essential, before our fee
- Type A 3-bed
- RM74k–118k
- Type B 3+study
- RM80k–128k
- Type C 4+study
- RM91k–145k
If you’re still deciding how far to go, tell us the figure you have in mind at the start. Because the walls can still move, a plan can grow quickly, and part of our job is to say what each move costs before you commit to it.
Can we start before the keys, and who will look after you meanwhile?
The design can start well before the keys, and one designer stays with you throughout.
We draw and manage; contractors you choose build it, from quotes we gather and go through with you, line by line.
- The discovery call FreeWhich type you’ve bought, who will live there, which walls you’re unsure about, and the spend you have in mind.
- The site visit RM200, waived if you go ahead with usBefore the keys we work from your sale plans. Once they arrive, we measure every room, mark the hackable walls and note what came with the handover.
- The scope, then the designRooms, fee and budget go in writing first. Then the plan: which walls stay, what the study becomes, how the kitchen and yard share the cooking, and the joinery around all of it.
- Drawings and quotesOne drawing set that every contractor prices the same way. We bring the quotes back, compare them with you, and you choose who builds.
- Works, then the finished roomsWe agree deliveries and working times with management, coordinate the trades, check each stage against the drawings, and style the rooms at the end.
A new building has its own first months: a management office finding its feet, rules still being written, neighbours renovating at the same time. We chase each form, deposit and delivery slot for you, so your weekends stay yours. The full process
Permits, and the management’s consent
TRiARA’s approving authority is the Petaling Jaya City Council (MBPJ), so your licensed contractor applies there for the renovation permit, with the management’s written consent, which matters most if a hackable wall is coming out.
TRiARA’s management hasn’t yet set out its renovation deposit, working hours or delivery rules. We get them in writing at handover, before contractors are asked to price anything.
What will your home hold that nobody else’s will?
Every TRiARA plan was left open to change, so we shape yours around the people moving in, starting with your mornings and whoever comes to stay.
Two Type B homes, one above the other, may start from the same walls on paper. In one, maybe two people work from the study and want its door kept. In the other, perhaps a grandmother lives with the family, and the study opens into a family room.
What TRiARA’s plans give you to work with
- KeepBaths, doorsThe elderly-friendly master bath, the wider front door, the entrance storage
- AdaptWalls, studyThe marked hackable walls, and a study to open up or close off
- AddBalcony, yardPlanters and light on the balcony’s water and power points; a hard-working yard
From Sime Darby Property’s published plans, which your sale agreement overrides. The full handover list isn’t out yet, so we check yours when the keys arrive.
What have owners around TRiARA spent on their homes?
TRiARA isn’t finished, so no one has renovated here yet. The closest guide is what owners in the Damansara townships around it have spent, as published records show.
Two 1,200 sq ft three-bedrooms at D’Erica Residence in Damansara Perdana, near a Type A in size, came to RM95,000–125,000 in about six weeks. A 600 sq ft home at Maisson Residence in Ara Damansara came to RM68,000.
The Damansara median is RM112 per sq ft, or about RM136,000 to renovate a 1,216 sq ft Type A. All are on our Petaling Jaya renovation cost index.

What to know while TRiARA is being built
Which TRiARA walls can come down, and when should that be decided?
The ones the developer’s plans mark as hackable: beside the kitchen in Type A, between the study and living room in Type B, between the study and third bedroom in Type C. Decide before any carpentry is drawn, and get management’s consent first.
Can two TRiARA units be combined into one home?
Sime Darby Property says selected units can be combined, up to 6+1 rooms, on its own terms. Ask the developer which pairs qualify before handover. If you go ahead, we plan it as one home, with one main kitchen and shared storage.
Does a TRiARA home suit an elderly parent?
It starts well. Each plan has a wider front door and an elderly-friendly master bath with room to turn a wheelchair, and Type C’s junior master by the entrance has its own bath. We add grab rails, a level shower and night lighting.
How much does it cost to renovate and furnish a TRiARA Type B?
A 1,507 sq ft Type B typically takes RM152k–278k to fit out and furnish at Curated (Commune, Cellini or Poet Living), or RM319k–668k at Bespoke (Space Furniture, BoConcept or Molteni&C), plus our design fee. Keep what the handover includes and it comes in lower.
With keys due in 2028, when should I start?
Begin about half a year ahead of handover. That leaves room for drawings and contractor quotes, and work starts once management approves. If you’re still deciding which walls to keep, or weighing a combined unit, talk to us sooner. The first call is free.
Can a TRiARA yard become the wet kitchen?
Often. The developer marks the yard for laundry and kitchen use, so a second hob out there is worth considering. We check its ventilation, drainage and power on site first, and keep the open kitchen for lighter cooking and serving.
Still weighing your plan? We’d be glad to talk it through.
Tell us your type, who’s moving in and which walls you’re unsure about, along with the figure you’d like to stay within. The first call is free, and your estimated design fee is written down before you commit to anything.
