Alpha Apartments Unit Types and Size Guide for Buyers is essential reading if you are considering a freehold Singapore condo for sale along Koon Seng Road in District 15 (D15), especially around the East Coast and Marine Parade area.
This guide by Homejourney breaks down the actual unit sizes, typical layouts and practical liveability of Alpha Apartments, so you can quickly decide if the available units fit your household needs and investment goals before you commit to buy a condo here.
As someone who has been tracking D15 properties and walking the Koon Seng Road and Joo Chiat stretch for years, I will also share local, on-the-ground tips you normally only hear from residents and long-time agents in the area.
Where Is Alpha Apartments and Who Is It For?
Alpha Apartments is a boutique freehold development at 98 Koon Seng Road, Singapore 427037, in the East Coast / Marine Parade planning area, within popular D15.[1][4][7]
Completed in 2005, it consists of one block with just 22 units over 5 storeys, giving it a low-density, private feel compared to larger East Coast condos.[1][2][4][7]
From a practical standpoint, Alpha Apartments tends to appeal to:
- Owner-occupiers who want a quiet, low-rise freehold home close to Joo Chiat, East Coast Road and Marine Parade
- Families who prefer larger, efficient layouts over flashy facilities
- Investors looking for D15 properties with relatively moderate quantum and proximity to lifestyle amenities

Alpha Apartments: Key Project Facts Affecting Unit Sizes
Before we go into individual layouts, it helps to understand the project scale and built-up intensity, as this directly shapes unit types and sizes.
- Tenure: Freehold condo apartment[4][7]
- District: D15 (Marine Parade / East Coast)[4][7]
- Site area: about 1,663 sqm land[1][4]
- Gross floor area (GFA): about 2,329 sqm[1][4]
- Total units: 22 units in a single block[1][2][4][7]
- Height: 5 floors[2]
- TOP / completion: 2005[1][2][4][7]
From URA-style metrics, a GFA of ~2,329 sqm over 22 units implies average strata sizes in the 100+ sqm range, which aligns with recorded sales in the 107–116 sqm (1,152–1,249 sqft) band.[3][6]
Alpha Apartments Unit Types & Approximate Sizes
Because Alpha Apartments is a small project, public data groups most transactions under generic unit types. However, we can still extract a reliable picture of typical sizes from URA caveats and market records.
Based on recent transaction data for Alpha Apartments on Koon Seng Road, unit sizes recorded include:
- Circa 107 sqm (1,152 sqft) – transacted in 2021[3][6]
- Circa 116 sqm (1,249 sqft) – transacted in 2021[3][6]
These are typical of generous 2- to 3-bedroom layouts in older freehold D15 apartments, often with larger living/dining areas and proper yard space.
Important: Exact configurations (2-bed vs 3-bed, penthouse variations) can differ from stack to stack. Always request the actual floor plan of the exact unit you intend to purchase through Homejourney’s project page Projects for verification.
Typical Layout Characteristics at Alpha Apartments
From on-the-ground viewing experience in nearby Koon Seng / Joo Chiat walk-up and low-rise apartments, Alpha Apartments layouts tend to prioritise liveability over cosmetic gimmicks. While individual units can vary, you can generally expect:
- Regular, rectangular living/dining space with good wall space for furniture
- Enclosed or semi-enclosed kitchen, often with a dedicated yard or service area – handy for families and helpers
- 2 or 3 proper bedrooms with space for at least a queen bed in the common rooms
- Master bedroom sized for a king bed plus wardrobes
- Balcony or planter in some stacks, though typically modest compared to newer launches
Older freehold developments like this often feel more spacious than similar stated sizes in newer mass-market condos, due to less space devoted to aircon ledges, large balconies and long internal corridors.
Who Should Choose Which Size at Alpha Apartments?
While unit types aren’t heavily diversified, the circa 1,150–1,250 sqft band can serve different buyer profiles depending on layout:
- Young couples / small families: A 2-bed-plus-study or compact 3-bed layout around 1,150 sqft can be comfortable, with room for a home office.
- Families with 2–3 kids: The larger ~1,249 sqft layouts, especially with 3 full bedrooms and a yard, are typically more suitable.
- Investors: 2-bed layouts may appeal to a wider tenant base (couples, small families, co-living pairs) and can be easier to maintain.
- Multi-generational households: Alpha Apartments may feel tight for 3 generations under one roof; consider it only if you’re comfortable with compact multi-gen living or use it as a base while parents remain in another home.

This is why many long-time East Coast residents still prefer older freehold apartments: even if facilities are simpler, the day-to-day living space feels more generous.
Buying Alpha Apartments: Key Singapore Regulations & Financing Rules
When evaluating Alpha Apartments for sale, you must consider Singapore’s national property rules. These apply regardless of unit type.
1. Buyer’s Stamp Duty (BSD) & Additional Buyer’s Stamp Duty (ABSD)
For any residential property purchase, you will pay BSD based on the higher of purchase price or market value, using IRAS’s tiered rates.[IRAS/HDB/URA – general knowledge]
ABSD may also apply depending on your residency (Singapore Citizen / PR / foreigner) and how many properties you already own. Always refer to the latest IRAS schedule and consider professional tax advice.
Insider tip: Many East Coast upgraders time the sale of their HDB or first condo to reduce or avoid ABSD. This requires careful sequencing of your sale and purchase timelines – a good conveyancing lawyer and experienced agent, together with Homejourney tools, can help you plan this safely.
2. Loan-to-Value (LTV) and Total Debt Servicing Ratio (TDSR)
The Monetary Authority of Singapore (MAS) caps housing loan amounts based on LTV limits and TDSR rules.[MAS – general knowledge]
