Here Are The Biggest HDB Flats You Can Still Buy Above 1,700 Sq Ft In 2026
Singaporeans like to make fun of how small HDB flats are, but you’d be surprised at the kind of variety that’s out there. Singapore has been building HDB flats for 66 years as of February 2026; and among the various kinds we’ve built, there are some genuinely huge units out there.
This week, we look at some unusual flats that are over 1,700 sq ft. For reference, a typical 5-room flat is between 1,185 to 1,240 sq ft. While most of these tend to be older, they’re still worth consideration for larger families; and if you were to pick a condo unit of the same size, it would reach well into $3 million.
As such, some of these may be a real bargain in terms of sheer spaciousness.

Why I like it
This is an executive maisonette, located in an HDB cluster that’s surrounded by private housing. This gives the area a quieter, less dense feel. There are various eateries within walking distance, and it’s a short walk to the park connector that leads towards the Serangoon River.
As a corner unit, privacy is noticeably better, and the layout reflects the strengths of maisonette living. The living and dining areas are nicely segregated, and the semi-circular protrusion in the living area adds extra space. While this shape can be a little tricky in terms of furnishing / interior design, it does create a sense of openness that’s rare in HDBs.
The living room balcony has been levelled out, and the double-volume ceiling here is a standout feature that brings in light and visual height. All three bedrooms are located on the upper level; not as ideal for older folk due to the stairs, but good for traditionalists who like keeping the communal and private areas separate. The kitchen layout allows for a service yard to be added if preferred, and there’s also a small utility room. Overall, every part of the home is well sized, which is increasingly hard to come by.

Why I like it
This jumbo unit sits within walking distance of Woodlands MRT station (NSL, TEL), with Causeway Point and other malls close by. Woodlands North Plaza, which houses a wet market, supermarket, and various eateries, is also within walking distance. For greenery, the nearby park connector leads to Admiralty Park and the Woodlands Waterfront.
The unit is on a high floor and enjoys an unblocked view overlooking Riverside Secondary School, bringing in plenty of natural light. The main door opens into a spacious foyer or balcony, which then leads to two separate entrances into the unit. This creates the potential for a dual-key configuration, which is rare for HDBs.
Inside, the living and dining areas are clearly segregated. There’s also a family room with a sizeable service balcony, adding another flexible communal space. The unit has five bedrooms, with the possibility of creating more if needed. Two bedrooms are ensuite, supported by a third common bathroom. The layout is efficient with minimal wasted space, making this a strong option for larger or multi-generational households.

Why I like it
Located within walking distance of Loyang Point, this executive apartment is well served by a supermarket and multiple eateries. It’s also a short walk to the park connector that leads directly to Pasir Ris Park and the beach, which adds lifestyle appeal.
The flat comes with four bedrooms and a huge living and dining area that immediately stands out. Two of the bedrooms come with balconies, which is extremely rare for HDBs. These balconies can also be accessed from the adjoining study or bedroom spaces, and they feature full-height sliding glass doors that make the rooms feel even larger and brighter.
The layout is regularly shaped, making furniture placement and renovation planning straightforward. Every part of the house is well sized, and the unit is in its original condition, which makes it particularly appealing for buyers who want to do a full revamp and customise the space to their preferences.

Why I like it
This jumbo unit is located right next to the future Teck Ghee MRT station (CRL), slated for completion in 2030. It’s also within walking distance of Kebun Baru Market & Food Centre, with additional eateries scattered around the neighbouring HDB clusters. Bishan–Ang Mo Kio Park is just a short walk away.
Sitting on a high floor, the unit enjoys an unblocked view and plenty of natural light. The main door opens into a sizeable foyer or balcony, and folding glass doors separate this space from the living area, making the entire front portion of the home feel larger and brighter.
The living and dining areas are nicely segregated, and the kitchen has an additional utility area built outside the original utility space. One of the original kitchens has been converted into a large study and walk-in closet, highlighting how flexible the layout is. There are six bedrooms in total, with two ensuite bedrooms and two common bathrooms. The unit is nicely renovated, allowing buyers to save significantly on renovation costs.

Why I like it
This executive apartment is within walking distance of Woodlands MRT station (NSL, TEL), Marsiling Mall, and a wide range of food options including a hawker centre and supermarket. The nearby park connector links to Marsiling Park, Admiralty Park, and the Woodlands Waterfront, offering excellent access to greenery.
The unit is essentially two door-to-door units combined into one, which means exclusive use of the lift lobby. It sits on a high floor, enjoys abundant natural light, and has two separate entrances, making it suitable for a dual-key arrangement.
Inside, the living and dining areas are spacious, and the master bedroom is particularly generous in size. The flat comes with four bedrooms, with the potential to create one or two more if needed. This is a rare configuration that offers both scale and flexibility, especially for extended families or buyers who need clearly defined zones within the same home.
