## Featured rationale

Sustained tenant demand and scarce new supply may continue supporting Gangnam rents, while forthcoming CBD completions could redirect leasing activity between districts.

## AI summary

Gangnam became Seoul’s most expensive prime office market for the first time, with Q2 2026 rents rising 6.3% to KRW136,200 per pyeong.

Q2 rents increased by 6.3% in the Gangnam Business District.

After six years without new prime office completions, Seoul's central business district (CBD) welcomed two new developments in the second quarter, while Gangnam Business District (GBD) overtook the CBD as the city's most expensive prime office market for the first time, according to Savills.

Savills said G1 Seoul, comprising 143,432 square metres, and Rene Square, with 60,387 square metres, were completed during Q2 2026. However, neither building was included in the latest vacancy analysis as active leasing is expected to begin next quarter.

According to Savills, G1 Seoul is being actively marketed to prospective tenants, while Rene Square is set to become the headquarters of the Serious Crimes Investigation Agency and its Seoul branch from October. Eul Tower is expected to complete by the end of 2026, with no additional prime office supply forecast for 2027.

Savills reported that average face rents across Seoul's prime office market rose to KRW131,300 per pyeong in Q2, representing annual growth of 4.9%.

The GBD recorded average rents of KRW136,200 per pyeong, narrowly surpassing the CBD at KRW135,200 per pyeong for the first time since Savills began tracking the market in 1997. Savills attributed the milestone to sustained tenant demand and a prolonged shortage of new supply. The Yeouido Business District (YBD) recorded average rents of KRW115,500 per pyeong, with rental growth accelerating as recently completed buildings continued leasing and stabilisation. Savills added that rents increased 4.5% in the CBD, 6.3% in the GBD, and 3.6% in the YBD.

Average maintenance fees also increased 3.0% year-on-year to KRW49,000 per pyeong, with Savills noting growth remained broadly in line with inflation.

### 江南租金首次超越CBD，成为首尔写字楼市场之最

在六年无新增核心写字楼竣工后，首尔中央商务区（CBD）在第二季度迎来两座新项目，而江南

第二季度江南商务区租金上涨6.3%。

据第一太平戴维斯（Savills）称，在六年无新增核心写字楼竣工后，首尔中央商务区（CBD）在第二季度迎来两座新项目，而江南商务区（GBD）首次超越CBD，成为全市最昂贵的核心写字楼市场。

第一太平戴维斯表示，建筑面积达143,432平方米的G1 Seoul，以及60,387平方米的Rene Square于2026年第二季度竣工。不过，由于预计下季度才开始积极招租，两座楼宇均未纳入最新空置分析。

据第一太平戴维斯称，G1 Seoul正积极向潜在租户推介，而Rene Square拟自10月起成为重案调查厅（Serious Crimes Investigation Agency）及其首尔分部的总部。Eul Tower预计于2026年底竣工，2027年暂无额外核心写字楼供应预测。

第一太平戴维斯报告称，第二季度首尔核心写字楼市场平均表面租金升至每坪131,300韩元，同比上涨4.9%。

GBD录得平均租金每坪136,200韩元，首次自第一太平戴维斯1997年开始追踪该市场以来，以微弱优势超越CBD的每坪135,200韩元。第一太平戴维斯将这一里程碑归因于持续的租户需求与长期新供应短缺。汝矣岛商务区（YBD）录得平均租金每坪115,500韩元，随着近期竣工楼宇持续出租并趋于稳定，租金增长加快。第一太平戴维斯补充称，CBD租金上涨4.5%，GBD上涨6.3%，YBD上涨3.6%。

平均管理费亦同比上涨3.0%至每坪49,000韩元，第一太平戴维斯指出增幅大体与通胀同步。
