Detached house construction cost calculator

This guide translates the Korean detached-house construction cost model for structure type, pyeong area, contract cost, ancillary work, design, permit, utilities, VAT, and original acquisition tax.

Construction unit costs

Light steel is referenced at KRW 5.2 million to KRW 8.7 million per pyeong. RC is referenced at KRW 7.0 million to KRW 12.0 million per pyeong in the Korean guide.

The calculator distinguishes advertised cost per pyeong from effective total cost per pyeong because design, ground work, utilities, demolition, exterior, and taxes can make the real cash need much higher.

Design, tax, and VAT

Design fee around 4 percent, minimum KRW 4 million, is used as a planning reference. Original acquisition tax 2.8 percent is modeled with related surtaxes when applicable.

VAT 10 percent can apply to construction service cost. National housing scale 85 sqm, about 25.7 pyeong, VAT exempt is treated separately in the Korean model.

Planning use

Use this estimate before comparing contractor quotes. Land cost, financing cost, retaining walls, road work, difficult ground, design changes, and owner-selected finishes can move the final budget beyond the initial unit-cost range.
