Rising costs push up payments for Seoul redevelopment owners
Owners in several Seoul apartment redevelopment projects are being told to expect much higher extra payments to receive homes in the rebuilt complexes.
At Eunma apartment in Gangnam, the estimated payment for an owner choosing the same-size home rose from 180 million won to 430 million won in a year.
Similar increases have been reported in areas including Apgujeong, Yeouido and Gaepo.
Construction costs are rising because of more expensive materials and labor, as well as competition to add higher-end designs and facilities.
Longer construction schedules also increase financing costs, while limits on adding homes can make it harder for projects to raise money through sales.
The Korea Institute of Civil Engineering and Building Technology's construction cost index reached 138.74 in August, up 5.98% from a year earlier.
Payments may continue to rise before construction begins, making redevelopment less likely to bring owners a profit.
Additional payments by members of major Seoul redevelopment projects have risen by hundreds of millions of won in a year, driven by higher construction and financing costs.
At Eunma Apartment, the estimated payment for an owner choosing a unit of the same size rose from 180 million won in September last year to 430 million won last month.
Costs have also climbed in projects in Apgujeong, Yeouido and other parts of Seoul.
The construction cost index reached 138.74 in August, up 5.98% from a year earlier.
Experts cited rising material and labor costs, longer construction periods and competition to add premium features as factors behind the increases.

What people are saying
External factors such as construction cost increases and the gap between sale prices and presale prices will cause additional payments to continue to rise.
Loans are unavailable, while additional payments and taxes are rising, so the burden is heavy.
It is almost meaningless to calculate current estimates.
With the 52-hour workweek and stronger safety standards, construction periods are getting longer and financing costs are increasing.
