Stacked Homes, in its 16 October 2026 review of Thomson Reserve, defined a mega development as a condominium with more than 1,000 units and used the definition to look back at how Singapore's largest launches have sold. Every one of them opened in a particular district, and the district is a useful frame: the neighbourhood's own history and its nearby supply shape the opening weekend, so the figures below read best place by place. The review was written around Thomson Reserve, a 1,268-unit project in Upper Thomson that opens for sale on 31 October 2026, and the earlier launches supply the yardstick for it.
Where the First Mega Launches Opened, Viewed From Union Square Residences
According to Stacked Homes, the first mega projects met concerns over privacy and a possible oversupply that could dampen price growth. Take-up on the opening weekend was muted: Parc Esta (1,399 units, launched 2018) sold 329 units, or 23.5%; Parc Clematis (1,468 units, 2019) sold 324, or 22%; and Treasure at Tampines (2,203 units, 2019) sold 272, or 12%.
Later Mega Launches Across the Districts, With Union Square Residences in District 1
Stacked Homes reported that take-up improved over time. Grand Dunman sold 550 of its 1,008 units (54%) on its 2023 opening weekend, and ParkTown Residence sold 1,041 of its 1,193 units (87%) at its 2025 launch. The 916-unit Chuan Park, which sits below the mega threshold, sold 696 units (76%) in 2024. Stacked Homes described the early concerns as having given way to confidence in better land optimisation, abundant facilities and profitable resale transactions, noting that mega condominiums have largely been profitable, with average annualised returns of 4% to 6%.
District 20, which covers Upper Thomson, Bishan and Ang Mo Kio, offers the closest local reading, since it is also where the next mega launch lands. Its last mega development was JadeScape, the 1,206-unit project on Shunfu Road, which sold 332 units (28%) at its 2018 launch. Stacked Homes added that most JadeScape resale units later reaped annualised gains of 4% to 6%. Also in District 20, AMO Residence, a 372-unit project off Ang Mo Kio Avenue 1, sold 98% of its units in its initial sales weekend in 2022.
Thomson Reserve's District 20 Debut, Seen From Union Square Residences
- Launch: Thomson Reserve, with 1,268 units, launches for sale on 31 October 2026, in a district whose last mega development opened in 2018.
- Position: Stacked Homes calls it the only mega development of 2026 and the first new District 20 launch since AMO Residence in 2022.
- Supply: Stacked Homes reckons the market is ready to absorb the project, because 1,268 units is a moderate increase relative to the size of the district, which spans Upper Thomson, Bishan and Ang Mo Kio.
- Pattern: across the launches above, opening-weekend take-up ran from 12% at the earliest examples to 87% at ParkTown Residence in 2025, with Grand Dunman at 54% in 2023 between the two.
