The real estate market adage "today's sale price is tomorrow's lowest price" is becoming a stark reality. Apartment presale prices in Seoul and the metropolitan area have surged unchecked this year, making "price shock" the new normal. Record-high prices are emerging even in complexes subject to price caps, which were designed as a safeguard against runaway costs.
With raw material costs and high exchange rates compounding the pressure, expectations that presale prices will rise further next year have become all but certain. As a result, competition to secure prime developments in the year-end presale market has intensified.
According to Real Estate R114, the average presale price for apartments in Gyeonggi Province reached 20.77 million won ($15,000) per 3.3 square meters as of early December. This represents a 31.8% surge from 2022 and has doubled over the past decade.
Even price-capped complexes are setting new records with each supply. Banpo Raemian Trinion in Banpo-dong, Seocho-gu, Seoul, exemplifies this trend, recording an average presale price of 84.84 million won per 3.3 square meters—the highest ever for a price-capped development.
The upward pressure on presale prices driven by raw material costs is expected to continue next year. The Korea Institute of Civil Engineering and Building Technology reported that the provisional construction cost index for October 2025 reached 131.74, indicating a 31.74% increase in construction costs over five years from the 2020 base year.
Market analysts point to exchange rate fluctuations as another significant factor. Higher prices for construction materials, which heavily depend on imports, add pressure to both construction costs and presale prices. Some forecasts suggest the won-dollar exchange rate could reach the 1,500 won range, spreading anxiety about next year's housing market.
Luxury developments are particularly vulnerable to exchange rate movements due to their heavy reliance on imported finishing materials. Additional costs from zero-energy housing construction and floor noise prevention measures are also contributing to higher presale prices.
"Raw material procurement contracts are typically annual, so the impact on construction costs hasn't been significant yet," a real estate industry official said. "We've been defending against real-time exchange rate fluctuations, but that protection won't last much longer."
This suggests that rising material costs from the high exchange rate could be fully reflected in construction costs and presale prices starting next year.
Premium Locations Draw Intense Subscription Competition
As rising presale prices become the norm, subscription applications are increasingly concentrated on landmark developments in prime locations offered before year-end. The main drivers are "asset protection psychology" and market polarization.
When presale prices are rising across the board, demand inevitably gravitates toward premium locations that hold value during downturns and rise elastically during upswings. Rather than paying high prices for developments in mediocre locations, buyers prefer to secure a "quality single property" with guaranteed future value as an inflation hedge, even at additional cost.
This is drawing attention to Harrington Square Gwacheon, currently on presale in Gwacheon, Gyeonggi Province, where housing prices have been rising notably.
Harrington Square Gwacheon is located in Commercial Block 5 of the Gwacheon Knowledge Information Town public housing district and comprises 359 units. Hyosung Heavy Industries is the builder.
Unit types include 108 units of 76 square meters (Type A), 54 units of 84 square meters (Type A), 27 units of 84 square meters (Type B), 81 units of 90 square meters (Type A), 54 units of 90 square meters (Type B), 27 units of 90 square meters (Type C), and eight penthouse units ranging from 108 to 125 square meters. The complex focuses on mid-to-large unit types designed for high residential satisfaction.
The model house opens on Friday, December 12, with subscriptions scheduled for Monday, December 15 through the Korea Real Estate Board's subscription portal.
The location stands out even within Gwacheon. Harrington Square Gwacheon will connect directly via underground walkway to Gwacheon Information Town Station on Subway Line 4, which is targeting a 2027 opening and is currently about 50% complete. This "direct station access" means residents can reach the subway without crossing roads or intersections.
The ability to avoid rain, snow, extreme heat, and cold makes for a comfortable commute environment. Such direct underground connections to subway stations are limited, giving the location high scarcity value.
The development also features an upscale exterior with a sophisticated curtain wall design that elevates Gwacheon's skyline. Each unit includes 9 to 10 pyeong (approximately 30 to 33 square meters) of multi-balcony space—rare for buildings of this structure—allowing residents to create home cafes, gardens, or hobby spaces according to their lifestyle.
The complex provides approximately 1.3 parking spaces per unit to reduce parking stress, and offers five or more elevators per floor. Maximum ceiling heights of 2.75 meters in living rooms, higher than standard apartments, create a sense of spaciousness even at the same floor area.
"This is the last golden opportunity to avoid the 'second wave' of construction cost and presale price increases expected starting next year," a Gwacheon real estate agent said. "Beyond simple price protection, the development offers rare high-end features like direct station access and multi-balconies. We're receiving many inquiries from Seoul and other areas, and expect the presale to proceed smoothly."
