Do you have elderly parents staying with you? Or are you planning to expand your family with more children? In a city like Singapore, with skyrocketing real estate costs, living with your partner, kids as well as your parents sounds like an impossible dream. This is where a 3Gen flat comes in; it’s a home specifically designed to fit three generations of a family living together. Read on to know what is a 3Gen flat, are you eligible for one and how to get the best 3Gen flat interior design using IKEA products.

To show you how Livspace and IKEA can work well together, we used a sample floor plan of a 5-room 3Gen flat at Bidadari Alkaff Oasis. Our designer, Vidati Jumati, envisioned this 3Gen HDB for a big family of six. Three generations, to be precise. She designed this home with IKEA furniture to help this multi-generational family live together comfortably.

What Is a 3Gen Flat?

These types of flats have always been popular among Singaporeans. A 3Gen flat is defined as a new type of HDB property that comes with more space as compared to other HDB flat. As its name suggests, a 3Gen flat is designed to comfortably fit multi-generational families under one roof. Typically, a 3Gen HDB flat has the following features:

  • Space ranging around115 sqm, or 1,237 sq. ft.
  • Four bedrooms with two attached bathrooms
  • Other essential rooms like kitchen, bathroom and living/dining areas
  • Storage shelter
  • Service yard

What Advantages Come With a 3Gen Home?

A HDB 3Gen flat comes with numerous advantages:

  • A 3Gen flat is much bigger and more spacious than other HDB flats
  • It can be easier to get a 3Gen BTO as up to 30% of BTO units are reserved under the Married Child Priority Scheme
  • A 3Gen flat interior design is perfect for both kids and the elderly
  • Such an HDB can help you save costs as you do not have to hire caregivers for your elderly parents or babysitters for your kids; in fact, you get to share all utilities between multiple people

What Are the Requirements for a 3Gen Flat?

To apply for a 3Gen flat, you need to fulfill one of the following eligibility criteria:

  • Married couple with parent(s)
  • Courting couple with parent(s)
  • Widow/widower with child and parent(s)
  • A divorcee with child and parent(s)
  • At least, one parent needs to be a Singapore citizen or a permanent resident

Sample Floor Plan of a 3Gen Flat Interior Design


This 3Gen HDB renovation is envisioned for grandparents (Lim and Lim), parents (John and Audrey) and two girls (Jessie and Joy) aged 8 and 5. This is the ‘family tree’ that our designer Vidati used to work on this 3Gen flat, spanning 115 sqm and furnished with IKEA furniture.

You step across the threshold and enter an open-plan living and dining room and kitchen. Next to the living room is the grandparents’ bedroom, and the remaining bedrooms lie beyond.

The Moodboard We’ve Followed for This 3Gen Flat Interior Design


Before we dive into the design details of this 3Gen flat interior design in Singapore, we wanted to introduce you to the theme we have followed. Here’s what our designer Vidati has to say about it:

“The mood was inspired by the Sweden summer. The furniture selections are modern in style—simple and clean cut—suitable for the Singaporean living style,”


3Gen Flat Interior Design #1: The Living Room

A modern setting with appropriate furniture for a family of six

This family, like every other family, loves spending time together in the living room and that called for a 3Gen flat renovation design that could accommodate everyone comfortably. This meant ample seating in the form of sofas, chairs and pouffes.

A TV unit with storage cabinets is very useful

For this living room, we followed a modern Scandinavian approach and outfitted it with all essential furniture that a family living room should have. We added a square centre table and aligned the furniture around it to give it definition and facilitate conversations.

Additionally, a TV unit and storage cabinet were combined to solve storage issues here. For lighting, we kept it simple with a single pendant light, track lighting and a floor lamp.

3Gen Flat Interior Design #2: The Dining Room

Playing up darker tones in the dining area

In stark contrast to the light colour palette of the living room is this dining area, with slightly darker tones. A 6-member 3Gen HDB can run the risk of getting too cramped with everyone gathered in one place.

And the best solution for this was including mirrors, which would visually elongate the space. Therefore, for the dining room, we used the Hovet mirror from IKEA, which fits perfectly on the chosen wall.

A 6-seater wooden dining table with black and white chairs are anchored in this 3Gen flat interior design by a pretty black woven rug. Illuminating this space beautifully are twin pendant lights from the house of IKEA.

3Gen Flat Interior Design #3: The Kitchen

Seamless black cabinetry for this open kitchen

When we were working on the home interior design in this HDB 3Gen flat, we were especially focused on the kitchen. We knew that this open kitchen had to look attractive yet have all the necessary accessories of a modular kitchen. The countertop and backsplash feature marble tiles, while the cabinetry is finished in matte black.

We’ve added an Industrial edge with the cement screed wall

Handleless cabinets look sleek in an open kitchen like this, while pendant lights above the breakfast counter create the right focus, ensuring a modern kitchen look in this 3Gen flat interior design.

3Gen Flat Interior Design #4: The Grandparents’ Bedroom

Interesting block trims on the wall add visual depth to the bedroom

Next it was time to move on to the biggest, prettiest and most comfortable bedroom while working on this 3Gen flat interior design in Singapore – the grandparents’ bedroom. Featuring a fully upholstered bed from IKEA and uber-functional PAX wardrobes flanking the bed, this bedroom is ideal for the couple.

A grey TV console matches with the wall

We also topped the flooring in this HDB 3Gen bedroom with vinyl, which, incidentally, is one of the best materials for bedroom floors. Refraining from harsh lighting, we went with Drum table lamps for the bedside tables and a matching ceiling light. Also, a TV unit with cabinets and open storage in grey plays well with the colour scheme of this room.

3Gen Flat Interior Design #5: The Parents’ Bedroom

A functional bed with an attached wardrobe from IKEA

The colour theme we followed for the parents’ bedroom in this HDB 3Gen home was simply white, perfect to give that Swedish summer vibe. Outfitted with the efficient and space-saving Platsa bed frame with doors, this bedroom has ample free floor space.

Additionally, the dressing area features a round wall mirror flanked by LED wall lights on either side and a display rack with hooks below. Ceiling track lights take care of providing lighting for the wardrobe.

3Gen Flat Interior Design #6: Jessie’s Bedroom

Filled with all the furniture that a little girl can need

A girl’s bedroom can’t get any brighter and chirpier than this pretty pink theme for the daughter’s bedroom in this 3Gen HDB flat.

A study table sits right next to the dresser

From storage cabinets to bookshelves and a dressing corner, this bedroom has everything that a young girl needs in her room.

A cute wardrobe with drawers and seating

On one side is the bed with storage baskets for Jessie’s toys and on the other, we placed the Sundvik children’s table. Also, some pretty wall art and a children’s armchair make for a cute reading corner for her.

3Gen Flat Interior Design #7: Joy’s Bedroom

A fresh green theme for this bedroom gives it a fresh pop

The tiniest one at home calls this fresh green-themed bedroom his space. The cute quotient of this 3Gen flat interior design was enhanced by adding a dinosaur wallpaper, which also worked as a great feature wall.

Toy storage unit attached to the wardrobe makes for additional storage

Flat woven rugs make the floor more comfortable. Moreover, we added a storage unit with baskets for this little one to keep his toys close. A children’s study desk and chair allow her space to play and read. The Smastad wardrobe with an attached toy storage unit completes the look.

3Gen Flat Interior Design #8: Bathrooms

Everything is in place in this ergonomic design

The bathrooms planned as part of this 3Gen flat interior design were planned carefully with sustainable materials. Also, all bathrooms come with glass shower cubicles and wall-mounted vanity units.

Homogeneous tiles for the parents’ bathroom
The shower cubicle is enclosed in a clear glass enclosure

While we went with a darker colour tone for the grandparents’ bathroom, the parents’ bathroom features homogeneous wall and floor tiles.

Pretty terrazzo pattern tiles in the kids’ bathroom
A functional storage rack

The standout feature in the kids’ toilet is the feature wall that mimics big terrazzo-like patterns. All bathrooms have ambient and task lighting – pendants, cabinet lights and LED wall lights.
