Semi-Detached vs Townhouse — What's the Difference and Which to Pick

Walking show units, many buyers cannot tell semi-detached from townhouse — similar looks, similar prices. Lived in, the privacy and space gap is clear.

The real difference

A semi-detached shares just one wall, leaving three sides open for parking or a small garden. A townhouse sits in a row; middle units share both side walls, open only front and back.

Trade-off

Aspect	Semi-detached	Townhouse
Privacy	More	Less
Surrounding space	Has sides	Front/back only
Price	Slightly higher	Better value
Typical location	Suburban	Closer in

Which to pick

Value privacy, multiple cars or greenery? Semi-detached, often for a small premium. Tight budget and want a central location? Townhouses give more space per baht. Choose by how you actually live.
