3 room flat renovations are generally and relatively faster in refurbishment turnaround time owing to a few reasons. The obvious reason being 3-room hdb flats in Singapore are smaller in sizes therefore the floor areas and wall spaces require shorter amount of time to complete wall finishes and flooring applications.

Tighter spaces to work with means more  constraint in the layout of furniture which is why most 3-room hdb flat owners prefer to keep the home styling simple, fuss-free and minimalistic to avoid cluttering. This translates to lesser built-in and custom furniture as well as furnishing, cutting down on both the time and renovation costs of 3 room flats.

3 room HDB flats have their fair share of eligible home buyers, i.e. families, siblings , joint singles and singles whose monthly income do not exceed S$5,000 qualify to purchase a 3 room flat in Singapore. Recently, singles above 35 years of age are also eligible to purchase brand new 2 room flats. This is the group who want homes to call their own and not having to stay with their parents; more often than not, basic renovations to satisfy moving-in condition suffice as they hope to move into their new apartments quickly.

HDB 3 Room Floor Plans

In Singapore, HDB 3 room floor plans are configured into several types depending on which year they were built. There was the 50 sqm model 3STS (3-room Standards) built in the early 1970s that has only one combined W.C./bathroom in the kitchen that houses a private rubbish chute. The slightly bigger model 3I (3 room Improved) that is of an average size of 60 sqm comes with separate toilet and bathroom.

In the 1980s, HDB developed the 3-room Simplified models that are about 65 sqm of average area, with a store room this time, and two bathrooms one of which is attached to the master bedroom. The rubbish chute system is also located outside the flat as a shared disposal system among neighbours staying on the same floor. The bigger 3NG (New Generation) models have their stores in the main living room space instead of the kitchen. The rarest and most spacious of all are the 3A models and they are usually the corner or end unit of a particular stretch of coridoor. Occupants who are staying in those built from mid to late 1980s that are corner units have longish floor plans that are of more than 70 sqm, or some were even modified to over 80 sqm. As such they have deeper set-in living hall areas that are narrow and long. While corner 3 room units are hard to come by these days as the hall and room offers open views as opposed to facing common corridors, the layout makes built-in cabinetry works such as tv consoles or racks extremely difficult because the built-up areas may make the circulation space even narrower.

Some older 3 bedroom flats come with only one bathroom/ toilet and is accessible from both the master bedroom as well as the kitchen. Such configuration will also cut down some time and costs in the HDB renovation package on toilet renovation works since there is one bathroom lesser.

Current 3-room flat designs include utility/ yard/ wet kitchen areas where the washing machine, fridge and clothes-hangars can be placed away from the main cooking areas. Such floor plans come with the wet areas separated from the dry areas, making the kitchen space more functional and cleaning easier. Smell and grease coming from the cooking will also not affect fresh laundry hanging in the utility area.

3 Room HDB Flat Interior Design

Illusion of bigger sense of space

Elongated layouts of 3 room corner units are most tricky, as the living area, and rooms tend to be long and deep, making circulation spaces extremely narrow, almost like passageways or corridors. When it comes to designing for such layouts, built-in carpentry as well as loose furniture have to be parked to one side in order to optimize space for circulation.

Alot of Scandinavian interior designs adopt such design configuration and the outcome can be tastefully done. This gives designers the opportunity to create an extensive length of a feature wall by playing with linear forms in creating depths and textures. The narrowness of the space can be countered by running adjacent lines across the longer lines of the space form, for example, by laying hardwood strips on the floor or having ribbed wood wall panelling.

Design forms and Finishes

It will also help if furniture such as couches and coffee tables are longish and sleek, and with finishes that are light-colored or organic light wood or light-reflecting glossy surfaces may all help in making the interior brighter and appear bigger in sense.

Space Configuration

Singles who bought resale 3 room HDB flats have the option of converting one of the two bedrooms as a study or home office. For such rooms, glass walls or incorporating see-though glass slats will not only allow a greater sense of depth of space but also allows sunlight from the room to come through to the main living space.

Amalgamation of spaces is also very common among 3 bedroom flat owners. If your living room is next to the common bedroom, or the master bedroom is next to the guest bedroom, you have the option to knock down the interparty walls to make your living hall or master bedroom much more spacious, provided that prior assessment and approval for such hacking and demolition works have been obtained from the Housing and Development Board.

Wall Treatment

Where wall treatments are concerned, try to do away with having murals or paintings or fancy patterns like stripes or stenciled wall designs or even elaborative wallpaper covering to further clutter the already limited space you have. Face the fact that there is a reason why art galleries have to be spacious for art pieces to be displayed and appreciated. Instead, play with one or two toned (one accented colour) paint colours as well as textures. Painting for a 3 room flat costs between $900 to $1,200 in Singapore, depending on the condition of the flat and whether or not the unit is vacant or occupied.


Decorative motifs may be opulent but without high ceilings and vast spaces to showcase and accentuate the contrasts these patterns bring, they compete with the other elements and thus clutter the space. For small spaces like 3-room flats, avoid furnishing like embroidered upholsteries, carpets and draperies, just to name a few.
