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.
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:

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.
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]
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:
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.
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:
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.
While unit types aren’t heavily diversified, the circa 1,150–1,250 sqft band can serve different buyer profiles depending on layout:

The table below gives a simple benchmark for buyers familiar with East Coast / Marine Parade condos:
| Development Type | Typical 2–3BR Size (approx.) | Feel |
|---|---|---|
| Alpha Apartments (freehold, 2005) | 1,152–1,249 sqft[3][6] | Older, more efficient, family-sized |
| Newer D15 mass-market condo | 800–1,050 sqft (2–3BR, many with larger balconies) | Modern, but more space in balconies/ledges |
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.
When evaluating Alpha Apartments for sale, you must consider Singapore’s national property rules. These apply regardless of unit type.
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.
