Last month, a client named Mandy excitedly told me, 'I finally found a unit I like! The usable area is 450 square feet, and the living room is so big and bright!' I asked her, 'Is it a diamond-shaped living room?' She looked puzzled: 'What's that?' It was only after she collected the keys that she realized, although the living room was spacious, its odd shape made it cramped once the sofa and TV cabinet were in place, and she didn't even know how to fit a dining table. This is the so-called 'diamond-shaped living room trap' that many first-time homebuyers encounter.
In Hong Kong's property market, developers often design special layouts called 'diamond living rooms' to maximize the usable area of a unit. At first glance, they look very attractive—spacious living room, plenty of natural light, and a luxurious feel—but after moving in, you realize that arranging furniture is a major challenge. Today, I will use my 15 years of real estate investment experience to deeply analyze the secrets of the 'diamond living room' and show you how to make the best use of the space while avoiding the most common design pitfalls in property purchasing guides.
Core Concept Analysis: What is a 'Diamond Hall'?
Definition and Characteristics of the Diamond Hall
"Diamond Hall" is a term in the Hong Kong real estate industry, referring to a living and dining room that features an irregular diamond or polygonal design. This type of design usually appears in the following situations:
- Corner Units: To accommodate the building's exterior corners, the living room may have angled or trapezoidal shapes.
- View Optimization Design: Developers deliberately distort the shape of the living room to ensure the windows face the best view.
- Efficiency Improvement: Through irregular designs, areas of the corridor that were originally 'wasted' are incorporated into the living room, making the usable area appear larger.
:::tip Expert Tip The biggest feature of the diamond-shaped living room is that "it feels very spacious when viewing the property, but only after arranging the furniture do you realize it's actually quite small." Because its irregular shape creates a lot of "dead corners," these areas are neither spacious enough to place furniture nor wide enough to serve as passageways, resulting in spaces that are practically useless. :::
Diamond Hall vs Traditional Square Hall: A Practical Comparison
| Comparison Item | Diamond Hall | Traditional Hall | |-----------------|--------------|----------------| | Usable Area | Appears larger on paper (5-10% more) | Appears smaller on paper | | Furniture Arrangement | Difficult, requires custom-made | Easy, standard sizes work | | Sense of Space | Visually open but actually cramped | More practical usable space | | Renovation Cost | 30-50% higher | Standard cost | | Resale Value | Harder to list | Easier to sell |
In the Hong Kong property market, the price per square foot of units in the diamond hall is usually 5-8% cheaper, but don’t think you’re getting a bargain. This is because the later costs of custom furniture, the difficulty of renovations, and the challenges of selling the property in the future could very well offset the money you saved initially.
How to Identify a Diamond Hall? 3 Must-Know Tips for Viewing Properties
Tip 1: Look at the Floor Plan Open the unit floor plan. If the living and dining area is not a standard rectangle or square, but instead has slanted lines or more than 4 corners, it is basically a diamond-shaped hall.
Tip 2: Measure on Site Bring a tape measure when viewing a property and measure the difference between the widest and narrowest points of the living room. If the difference exceeds 2 feet (about 60cm), arranging furniture will be quite tricky.
Third Tip: Ask the Developer Clearly Directly ask the real estate agent or developer: 'Is this unit designed as a diamond hall?' A professional agent will answer frankly. If they hesitate, you need to be extra cautious.
:::warning Pitfall warning Some developers use beautifying terms like 'special design' and 'landscape-optimized spacing' to package diamond living rooms. Remember, any living room design that deviates from the standard rectangular shape requires special attention to practicality issues. :::
Practical Case Sharing: Complete Guide to Furniture Arrangement in the Diamond Hall
Case 1: 450 sq. ft. Diamond Hall One-Bedroom Unit
This is a real case I handled for my client Mandy. The unit is located in a new development in Tseung Kwan O, with a usable area of 450 square feet. The living and dining room is trapezoidal, with the widest part being 18 feet and the narrowest part only 10 feet.
Original Layout Dilemma:
- The sofa is placed in the wide area, but the TV cabinet has to be placed in the narrow area, making it hard to watch TV
- There is no place for the dining table, so only a folding table can be used
- A dead corner of 50 square feet is completely unusable
Expert Solutions:
- Abandon the traditional 'sofa facing the TV' layout
- Arrange the sofa in an L-shape along two walls - Mount the TV on the wall, no TV cabinet, saving 1.5 feet of depth - Use a projector screen instead of a TV, only set it down when needed
- Make Good Use of Corner Spaces for Storage
- Customize triangular storage cabinets to fill in slanted corners - Tall design (up to the ceiling) to increase storage capacity - Use mirrored cabinet doors to enhance the sense of space
- Dining Table Transforms into a Multi-Functional Work Desk
- Use a extendable dining table, normally kept small as a desk - When guests come, extend it to serve as a 4-person dining table - Place it by the window to make the best use of natural light
:::success Success case After replanning, Mandy's apartment not only solved the furniture arrangement problem but also gained 30% more storage space. Most importantly, the whole home feels more spacious and no longer gives the feeling of 'having bought a big living room but not being able to use it'. :::
Case 2: 600 sq. ft. Diamond Hall Two-Bedroom Unit
This is a corner unit in a housing estate in Sha Tin. The living room is rhombus-shaped, with 5 corners. The owner, Raymond, is a professional investor who bought it for rental purposes, but tenants said after viewing that the furniture is difficult to arrange, and as a result, it was vacant for 3 months.
Insider Solution:
Strategy 1: 'Correct' the shape of the space with furniture
- Custom-make an L-shaped sofa to fill one of the angled corners
- Use a tall bookshelf as a divider to split the irregular space into two square areas
- Use one side as a living room and the other as a workspace
Strategy 2: Reduce the Amount of Furniture
- Don't be greedy and put out all the furniture
- Only put out necessities: a sofa, a dining table, a TV cabinet
- Leaving empty space actually makes the unit look more comfortable
Strategy 3: Unify the Visuals with Lighting and Colors
- Use the same color scheme throughout the house (light wood + white)
- Use spotlights to illuminate dead corners and reduce dark spots
- Avoid using dark furniture, as it will make irregular shapes more noticeable
:::highlight Expert Opinion The key to successfully renting out a unit in the Diamond Hall is to 'make it feel easy for tenants to live in.' Don't think about filling it up completely; instead, leave some space for tenants to add their own furniture. After I helped Raymond redecorate, the unit was rented out within 2 weeks, and the rent even increased by $1,000. :::
5 Golden Rules for Furniture Placement in the Diamond Room
Based on my many years of experience handling diamond hall units, I have summarized the following rules:
- Prioritize the 'main pathways': Ensure the routes from the front door to the kitchen, bathroom, and bedrooms are unobstructed, and don't let furniture block them.
- Custom furniture is a necessary investment: 90% of standard size furniture doesn't fit well, so it's better to order custom furniture from the start.
- Vertical space is most important: Diamond-shaped living rooms usually have high ceilings, so use tall cabinets to increase storage.
- Less is more: Don't force yourself to place all the furniture; leaving empty space can actually make it more comfortable.
- Use mirrors and glass to enhance the sense of space: Mirror cabinet doors and glass partitions can make the space feel visually more open.
Notes and Risks: Must Read Before Buying Diamonds
Common Misconception: Thinking that a larger usable area means a better deal
Many first-time homebuyers make this mistake. When seeing two units, one a 450 sq ft standard apartment selling for $6 million, and the other a 480 sq ft premium apartment selling for $5.8 million, they think the latter is a better deal. But in reality:
Hidden Cost Calculation:
- Extra expenditure for custom furniture: $80,000-120,000
- Increased difficulty in renovation: 30-40% more cost
- Difficulty in air conditioner placement: may need to install a window unit
- Troublesome future maintenance: technician fees may be higher
Resale Risks:
- The average listing time for units in the Diamond Hall is 30-40% longer
- There is a larger room for negotiation; buyers will bargain
- The target customer base is narrower, mainly investors or designers
:::warning Professional Advice If you are part of the first-time homebuyer group and have a limited budget, I would suggest buying a smaller unit with a regular layout. Because of the extra expenses for a diamond hall, that money could potentially cover your mortgage cheaper than rent for an additional two years. :::
Be Careful with Mortgage Appraisals
Bank appraisers are usually more conservative with units in the Diamond Hall, the reason is:
- Few comparable units: The same estate may only have a few Diamond Hall units, making comparison difficult.
- Lower market acceptance: Appraisers will consider the difficulty of resale.
- Practicality discount: The appraisal may be discounted by 5-8%.
Actual Impact: Suppose you buy a diamond hall unit for $6 million, the bank's valuation might only be $5.7 million. If you take an 80% mortgage, you will need to prepare an additional $300,000 as a down payment, or accept a lower loan amount.
Lower rental yield
If you are a real estate investor, you should note that the rental yield of units in the Diamond Hall is usually 0.3-0.5% lower. The reason is:
- Fewer tenant choices, stronger bargaining power
- Longer vacancy periods, affecting annual returns
- Some tenants may terminate the lease early due to furniture arrangement issues
Actual Data Comparison (Using Sha Tin District as an Example):
- Fang Ting 450 sq ft Unit: Rent $15,000, Yield 3.0%
- Diamond Ting 480 sq ft Unit: Rent $15,500, Yield 2.7%
Although the Diamond Hall is larger, the actual return is lower because the purchase price is higher.
In what situations can one consider the Diamond Hall?
It's not that the Diamond Hall is necessarily bad; the following situations can actually be considered:
Suitable for people:
- With ample budget: Have an extra $100,000–150,000 for custom-made furniture
- Long-term residence: Not in a hurry to list the property, can slowly enjoy the space
- With a design concept: Know how to make good use of irregular spaces
- Value the view: Diamond halls usually have better views, if this is important to you
Additional Advantages:
- High ceiling units (over 10 feet), allowing the construction of a loft to increase usable space
- Located in a prime area, where the location advantage can offset the layout disadvantages when reselling
- Developer provides furniture packages, saving on custom furnishing costs
:::tip Insider tips If you really like a unit in a diamond hall, I suggest you find an interior designer to accompany you when viewing the property and assess the feasibility of furniture placement on the spot. This consultation fee of $2,000-3,000 can help you avoid a $500,000 loss from buying the wrong property. :::
Summary: The Diamond Hall is not a terrifying monster, but you need to know how to choose and use it wisely
After the detailed analysis above, I believe everyone now has a comprehensive understanding of the 'Diamond Hall.' To sum up a few key points:
Advantages of the Diamond Hall:
- Usable area is generally larger
- Views and lighting are generally better
- Price per square foot is relatively lower, with room for negotiation
Disadvantages of the Diamond Hall:
- Difficult furniture arrangement, requires custom-made pieces
- Renovation costs 30-50% higher
- Resale is more difficult, longer listing time
- Bank valuation may be more conservative
My professional advice:
If you are a first-time homebuyer with a limited budget, I would suggest giving priority to units with a regular layout. It’s better to buy a 30 sq ft smaller but functional square living room than a 30 sq ft larger but awkward diamond-shaped living room.
If you are a professional investor, unless the diamond hall unit has other strong advantages (such as an extremely good price or a prime location), it is better to choose the traditional layout, as both renting and reselling will be much smoother.
But if you have a sufficient budget and know how to appreciate and make good use of irregular spaces, a diamond-shaped hall can actually create a home full of character. The key is to do your homework, find the right designer, and not to be tempted to buy the wrong property cheaply.
Remember, the most important thing about a property buying strategy is that it should be "suitable for yourself." Don't blindly follow trends, and don't rush into the market just because something is cheap. In the competitive environment of the Hong Kong property market, every decision must be carefully considered.
