27 New Launch Dual Key Condos To “Avoid” ABSD In 2023

Whether it’s for extended families or rentals, dual key units are one way to split your property and avoid the Additional Buyers Stamp Duty (ABSD). There is, however, a wide range of dual-key layouts; and not all are equal. Some are better for own-stay use, others for taking on tenants – and as most seasoned investors can tell you, a higher price per square foot is a common issue. Here’s what to consider when picking your unit:

A quick run-down of dual-key units

Dual key units are individual properties, which have been subdivided into two. Both halves of the property can be inhabited, with residents having little to no direct contact. In this sense, a dual-key unit is a bit like a condo version of a semi-detached house. 

Dual key units are commonly pitched as a way to avoid ABSD. This is not literal: you would still pay ABSD if a dual key unit is your second, third, or subsequent property. The idea is simply that a dual-key unit saves you from having to buy two different properties. 

That said, not all condos have dual key units, even if they were very popular at one point. As and when they exist, dual key units tend to make up only a small portion of the available units. The variances between these units can be huge (e.g., a dual key unit can be a two-bedder, or it can be as big as a four or even five-bedder). 

Most dual key units cost more per square foot than their usual counterparts, but the degree of price difference varies greatly between projects. 

We’ve done a comprehensive list of 121 dual key condos before, but if you are looking for something more recent, here’s a list of new launch condos with dual-key units:

What to look out for in dual-key unit layouts 

• Utilities vs. living space 
• Upstairs and downstairs, or side-by-side
• Which utility rooms are shared 
• Overall shapes of the rooms
• Flexibility for future renovations 

1. Utilities vs. living space

The main difference between dual key units and regular units is the doubling of utility rooms. A split unit, for instance, requires an additional kitchen, additional toilet, duplicate storage spaces, and so forth. Do remember that the kitchen space for the smaller unit is almost always more of a kitchenette/pantry rather than a proper kitchen – so there will have to be some compromise there.

This duplication means the square footage of dual key units can be misleading. You can end up with much smaller living rooms, bedrooms, and studies after the added utilities. E.g., a 1,000 sq. ft. dual-key unit may have 600 sq. ft. of actual living space after the extra utility rooms, whereas a regular 1,000 sq. ft. unit in the same project may have 700+ sq. ft. 

When picking a unit, it’s important to ensure you’re happy with the distribution of utility to living space. If your purpose is to house an extended family (e.g., your parents are moving in with you), consider if more living space would trump the added privacy of a dual-key unit. 

(Don’t forget that a similar-sized, normal unit is also likely a bit cheaper). 

2. Upstairs and downstairs, or side-by-side

Some dual key units are arranged such that the top and bottom floors are well divided. In these cases, your tenant can live upstairs or downstairs, while you take the other floor. 

More dual key units, however, are arranged to be side-by-side. A common setup is to have a joint entrance, with two doors leading to subdivided units. 

In general, most buyers seem to prefer the side-by-side layout. This is simply to spare one set of residents the trouble of having to walk upstairs. This is also true for extended families, where owners may not want elderly parents to have to walk upstairs to visit them. 

However, some buyers may feel that an upstairs and downstairs unit offers a greater degree of privacy; and in some layouts, it’s even possible for a tenant and landlord to enter these respective units without seeing each other. 

3. Which utility rooms are shared

Some dual key units compromise a bit on the degree of separation. In some layouts, for instance, there is a shared kitchen rather than separate small pantries. This may be a better setup for extended families, where meals are still shared even if living spaces aren’t. 

There are also some layouts that, with the renovation and movable walls (see below), have allowed the joining of certain rooms (e.g., shared dining room). 

This is where landlords and family units differ. Whilst extended families may want to share some spaces, landlords usually want the highest degree of separation possible – especially if they intend to have unrelated tenants in both halves. 

4. Overall shapes of the rooms

Dual key units necessarily lose some efficiency due to the sub-division, but some may end up with the occasional odd-shaped room. Ideally, you still want all the rooms to be squarish, if for nothing besides interior design simplicity.

Rooms that are wedge-shaped, too long and narrow, or round can be problematic and uncomfortable later. It’s generally better to have squarish rooms, than to have rooms with more square footage but are odd-shaped (all the nooks and crannies are probably not usable spaces anyway). 

5. Flexibility for future renovations

Do check which walls are movable, and which are not. Ideally, a dual key unit is so flexible that you can even demolish the subdivision later, and merge it into a regular unit (but this is a tall order in many projects). 

At the very least, check if you have the leeway to merge certain rooms later. These can allow your unit to appeal to a different demographic (e.g., extended families rather than just landlords), at the point of resale. For genuine homeowners, this also helps in the later change of life circumstances (e.g., you want to look after ageing parents more closely, and would prefer they aren’t isolated in the sub-unit). 

As this is complex to estimate on your own, we suggest speaking to a contractor or Interior Designer regarding the floor plan.
