Corner units, top floors, and ground-floor units are each a trade-off between clear strengths and weaknesses. Whether the price difference is worth paying depends on your day-to-day priorities. Below, we lay out the characteristics of each, how to think about asset value, and points to keep in mind when choosing.
- A corner unit (kadobeya) is bright, with more windows and fewer adjoining neighbors, but it has more exterior-facing walls, which tends to work against heating and cooling efficiency.
- A top floor (saijōkai) has no noise from above and often enjoys a great view, but you need to watch out for summer heat, dependence on the elevator, and a substantial price premium.
- A ground-floor unit is easy to come and go from and frees you from worrying about footstep noise below, but checking security, humidity, and flood risk is essential.
- Corner units and top floors tend to be easier to resell in the future, but it's important to judge that against the premium you pay to buy in.
Conclusion
Corner units, top floors, and ground-floor units each carry clear strengths and weaknesses. Whether the price difference is worth paying depends on your day-to-day living style and what you prioritize. Rather than judging by position on the floor plan alone, it's important to weigh the actual characteristics of each. Sorting out early on, at the start of your home search, how much value you place on each condition helps lead you to a choice you'll feel good about.
Corner Units
A corner unit tends to be bright throughout, since its windows face multiple directions, and having a neighbor on only one side reduces noise stress. On the other hand, it has more exterior-facing surface area than a mid-unit, so it tends to run hot in summer and cold in winter, putting it at a disadvantage for heating and cooling efficiency. Weigh these characteristics against the price, which is often set higher than a mid-unit. During your viewing, it's reassuring to check for yourself how much of a difference you actually notice in airflow and natural light.
Top Floors
A top-floor unit lets you avoid worrying about noise from the floor above, and it also tends to offer value like a view and a sense of openness. On the other hand, being close to the roof, it tends to get hot in summer, and the impact of an elevator outage is greater. The price premium also tends to be larger than for a mid-floor unit, so it's important to calmly weigh the value you get against the price you pay. Whether the view from the rooftop or shared facilities is preserved is also a factor that affects your day-to-day satisfaction.
Ground Floor
A ground-floor unit offers the ease of coming and going without stairs or an elevator, and the peace of mind of not having to worry about footstep noise bothering the floor below. Some ground-floor units also come with a private garden, which is a charm unique to this floor. On the other hand, you'll need to check things like security considerations, humidity control, and flood risk in advance using a hazard map, among other sources. Whether the flow from a full-height window works well as part of your daily traffic pattern is also worth checking during your viewing.
How to Think About Asset Value
Units with conditions "many people care about" — like corner units and top floors — tend to be easier to find a buyer for when you eventually sell. In that sense, they can work in favor of asset value, since the price tends to hold up better, but that also tends to mean a larger premium at purchase. It's important to weigh future resale ease against the extra amount you pay now. Since conditions differ unit by unit even within the same building, it's also useful to compare several units side by side.
How to Choose
How hot or cold a unit feels also depends heavily on insulation performance and which way the building faces. Rather than judging uniformly by position on the floor plan, we recommend confirming natural light, airflow, and the surrounding environment for yourself, in person, during a viewing. Understanding the characteristics of corner units, top floors, and ground floors, and then choosing the unit that fits your own way of living, leads to a choice you won't regret. Don't hesitate to ask the person showing you around about anything that concerns you, and avoid moving forward to a contract with unresolved questions.
Frequently Asked Questions
What's better about a corner unit compared with a mid-unit?
It has more windows and is brighter, and having a neighbor on only one side tends to reduce noise stress. On the other hand, it has more exterior-facing surface area, which tends to work against heating and cooling efficiency.
Should I avoid a ground-floor property?
Not as a blanket rule. Checking security, humidity, and flood risk is necessary, but a ground floor also has its own value — the ease of coming and going, not having to worry about the floor below, a private garden, and more.
Does a top floor have higher asset value?
It tends to be easier to find a buyer for, but the price premium at purchase is also larger. It's important to judge based on the balance between future resale ease and the extra amount you pay now.
Summary
Corner units, top floors, and ground-floor units each have clear strengths and weaknesses. Rather than judging by price difference alone, sort out what you prioritize based on your own way of living, and confirm the actual livability through a viewing.
